Yes, it is a lot fantasy. It is a Bonkers test lab, after all. But the stuff I detailed in Part 1 is realistic and achievable. The Kingston Hyper-X array should also be realistically achievable for most, if the "high speed storage" part of the equation appeals to you.
The 10Gbit network with added WTF was built as much to see "can it be done" as anything. My hope is that having such a test lab lying around will allow me to do better reviews on more relevant equipment for The Register than I would otherwise be able to do.
Do we want to limit ourselves to reviews of the latest iPhone or consumer home NAS? Or do we want to occasionally tear apart some bit of midsize gear or even enterprise kit? If we do want to be able to throw that more powerful equipment on the bench and give it a run for its money, someone is going to have to build a bonkers test lab. So I did.
My testlab will ultimately run Windows, VMware, Openstack, Cloudstack, various flavours of Linux and several BSD disties that I am playing with. Don't worry though, I'm totally a paid shill for [corporation_you_hate] as well as a religious freetard while simultainiously lacking any understanding of anything because I don't do what [commenter_1] says AND what [commenters2-n] say, despite the fact that they all completely disagree.
I write things on the internet, getting on 3 years now. After a time, it's all déjà moo. The handles attached to the blocks of text may vary, but the level and stinkyness of the bullshit contained in that text does not.
That said, the chief grand poohbah around here gave me a gold commenttard badge, and that is a great thing. It comes with an ignore button. The SNR has increased dramatically since I started using it.
Re: 2.5" bays for 5.25" holes.
Seriously; we had the Icy Docks on order at the local computer retailer. They were all set to arrive...then didn't. Oh, but they'll arrive! They'll be here in time for your review! Nope. Really should have bought from an etailier instead of waiting for the local retailer to get kit in, but ya can't win 'em all...
Re: Bypassing the usual flamewars...
Are you asking about the UPS from the dark ages, or the terrible IBM rack? Or the built-like-a-tank-will-never-ever-ever-ever-ever-die orange chair of doom?
Don't question the chair. The chair is indestructible. (And it has an equipment seatbelt.)
For the record though, we spent all night racking stuff last night...
There has been a lot of questions about this. I have put it on my list, I promise you. :)
I did; but I couldn't get anyone to send me Infiniband gear, nor are there local suppliers that offer it cheap. So if I did invest, it would a) be stupid expensive and b) I would be in deep ca-ca-poo-poo if anything whet splor and I needed a spare ASAP.
I call this my "test lab," but I should point out that my "live" corprate VMs occupy 1/5th of this particular setup at any given time. (Actually, they fit just fine in a single Eris 1 node, but that's a whole other story...)
I would love to test, review and otherwise learn about infiniband. With luck, some will show up on my doorstep one day.

Re: Weekend disinfecting Linux?
The Mac was infected via Java. *sigh*.
I have no idea what got the Ubuntu; it was rooted and compromised beyond my ability to repair, I ended up pulling the data and burnign the system. The Fedora was compromised becuase some twunt refused to update the system, and the dude walked in through an SSH bug. (Easy to guess user password +running SSH on default port makes me sad.)
Re: Eadon's Tough New Security Plan
Having spent the majority of my weekend disinfecting two Linux VMs - one Fedora Core 12, the other Ubuntu 8.4 - as well as a Mac (Leopard) ...
...fuck you, sir. Those platforms do indeed need anti-malware. More to the point, they need anti malware that doesn't suck. Windows needs it more urgently, but all platforms are suffering.
Oh, and I personally got hit by that Internet Explorer 0-day on Saturday too. I use IE once in 3 months...BAM! Sirefef. Well thanks, Microsoft. And a great pick "up yer jacksies" to whatever assclown wrote the damned viruses in the first place, too.
VMware is an example of a company that just bet the farm on Flex; their new interface is entirely Flex, and I doubt they have all that much interest in porting. (In fact, I seem to recall one of them discussing at length that HTML5 was not remotely close to as capable as Flex for rich applications like the vSphere management tools.)
You can call that "a company with a vested interest" in keeping Flex alive if you want; but it's a Big Player and I suspect it won't let Flex just die.

Re: that "dangerous" bit about augmented reality
Oh, there are many - many - dangers underlying augmented reality. Before we even begin to get into information overload, overreliance on search engines (lack of learning the fundamentals!) and other such things, let's stick to the easiest and most basic:
Augmented reality is to the entire rest of your life what texting is to driving. Don't compute and walk; you'll only enrichen the lawyers. Mine's the one with the "suing for whiplash for dummies" in the pocket...
@Stevie I use Windows every day. I use Linux every day. I bash (and praise) both as I see fit. I qualify as loud.
@JDX Linux can go toe-to-toe on many things...but I honestly think MS pipped Linux on the storage front this go-round. And Hyper-V is more or less a match for anything Linux can offer...but with far superior management tools available from both Microsoft and third parties.
Really, the question is: do you manage everything from the command line, read all reports encoded, as text or as HTML...or do you have your staff doing more than just one task? If your staff do more than just the one thing (virtualisation admin, storage admin, network admin, etc) then the reality of the world is that they won't have time to memorise all the commandline details that would be required to do their jobs efficiently using that interface.
Chances are then that a GUI for day-to-day monitoring, maintenance and minor changes are better suited for these individuals, with scripting automating the bulk of the regular work. (Scripting used solely for automation can be done with the textbook beside you, it doesn't require rote memorisation of all the commands.)
In the latter case, good management tools matter. It is here that Microsoft has consistently been ahead of Linux. Is the commandline – and specifically the Linux commandline – better than Microsoft's offerings? Hell fucking yes. If you live and breathe commandline for administration of your daily tasks, accept no substitutes!
But there are rather a lot of admins out there who don't be narrowly focused experts. For them, good management – and monitoring – tools matter. MS did a good job on that here. (RSAT, SCVMM, SCOM, etc.) Credit where it's due.
Want, want, want. Want, want. Want.

Re: @Trevor_Pott - Still not getting it
@Steve Todd; the same deals are very likely available to everyone. Assuming they sit down to the negotiating table. But all negotiations start at the same place. That's FRAND.
The standards bodies knew exactly what Moto charged for those patents when they chose them. Moto has been remarkably consistent about their patent licensing for ages. This isn't some new change on their part. It is Apple, Microsoft et all choosing to litigate as a means of attempting to restrict competition rather than bothering to negotiate, licence and compete on a level playing field.
Apple, Microsoft et al are basically trying to turn FRAND patents into something worthless. Nobody is going to bother to put forth a patent to a FRAND pool – or even participate in a standards process – if FRAND patents basically mean "nobody has to pay anything, because they can simply refuse to negotiate and then outspend you." Instead, companies that actually do the real innovation – making the products and technologies that should be in FRAND in the first place – will bide their time, not announce that thye have relevant patents to the standards process, then whack everyone after the patent is settled. (By not having taken part, they aren't subject to the "call for patents" and certainly can whack people who use similar-enough items to those which they hold patents on.)
I suspect that Microsoft and Apple are trying very hard to kill the standardisation process. It is part of a wider anticompetitive strategy no different than their wailing and gnashing of teeth about Google's supposed "abuse of search monopoly" which was rightly stepped on. (Or blowing up Google's dropping of the ball regarding Windows Phone and maps, which isn't – and wasn't – nearly the scandal Microsoft's PR folks tried to make it into.)
If you wanted to complain about someone committing to a patent pool at a given rate with a FRAND patent, then changing their mind…go right ahead. That isn't what Moto is doing. Moto is charging an outrageous sum for the FRAND patents they hold; but it is the same sum they ask of everyone, and they have been asking it for a good long while.
Apple and Microsoft are not even the first to get right uppity about it, though Apple's "we're not going to negotiate, we're just going to go straight to the judge and whine like a blinkered bitch" is a novel approach to the whole process.
So really, we can go round on this. You seem to be under the impression that Moto can't ask "a ludicrously large sack of money" up front. I am trying to tell you that is bullshit: they can. They simply have to ask for the same amount from all. They do not have to be cheap. They ideally should be, however nothing compells them to be. And that, as they say, is get of my goddamned lawn.
Re: @Trevor_Pott - Still not getting it
@Steve Todd you are completely incorrect.
The whole point of FRAND is to level the playing field. As long as the same stating offer is made to all players, then the amount can be negotiated lower. They only have to prove they started negotiations at the same point. There is no requirement to prove that others were required to pay that starting request. (Which, IIRC, they actually have proven in court as part of Apple's discovery at least once.)
Again; you are basically saying that the value of cross licensing is zero. All that matters is the "sticker price." That is A) bullshit and B) not upheld by current law. Sorry.
@Doogie1 if you approached FRAND with no biases and preconceptions you would realise that the licenceing concept as defined and as in use by most companies today is actually quite open ended and subject to a lot of interpretation. It isn't defined law but rather more of an industry-wide "gentleman's agreement" that pretty much everyone pisses on when they feel like it. From the licensors to the (especially in mobile) the licences.
They are all pretty much shit in the mobile game. Apple, Moto, Microsoft and more. Not a bloody one of them has the moral high ground here. That said, nobody has been able to present any evidence that Moto breached the letter of the "agreement" that is FRAND. They offered Apple the same deal they offer everyone. The fact that Apple - and some commenters - don't like that deal isn't relevant at all. It is the point from which negotiations are supposed to start. The same point everyone starts from.
Even the $30,000 car manufacturer. (And yes, people have entered negotiations with car manufacturers from a "% of the MSRP of the shipping unit" standpoint.)
That is what FRAND is. Not "cheap" but rather "level playing field."
Re: @Steve Todd
I don't think that means what you think it means. Certainly in the context of FRAND. FRAND is nothing to do with not discriminating based on device. It has everything to do with not discriminating based on company. FRAND is about offering potential licensees equal access to the patents; everyone playing by the same rules.
Nowhere does it state that it must be a flat rate per device. In fact there are many FRAND devices that discriminate quite directly per device; X amount per DVD player, Y amount per desktop, Z amount per mobile and so forth. The critical bit is that if 5 mobile companies all come to you and say "I want to use your patents in my device" you tell them "it will cost you X per device," and X will be the same. There is nothing in FRAND rules about a % versus a fixed amount. Both have been used by various companies at various times.
Even if you want to go about it from a moral perspective, you can easily argue the "fairness" and "non-discriminatory" nature of a % versus a fixed amount. It all depends on which biases and preconceptions you approach the argument with. In the case of FRAND, the only real issue is "the same standards are applied to all licences."
FRAND != cheap. FRAND = "level playing field."
Why should Motorola divulge the rates that other companies have negotiated, especially when those rates likely include cross-licensing agreements which will affect the price. All Motorola has to do is demonstrate that its beginning negotiations positions has always been 2.5% to all players, a position which - from there - it generally negotiates.
2.5% of the value of the device is the value Motorola intends to see for it's patents. That does not have to be in raw cash. It is often largely compensated for by cross-licenceing, with a little bit of cash on the side. That is fair, reasonable and non discriminatory. Note that FRAND does not mean cheap. It means "everyone who wants access to these patents must be able to licence them" and "everyone who wants access to them has to play by roughly the same rules."
Moto offered Apple a licence, under the same terms it has offered every other company who wanted access to those patents. Rather than negotiate from this starting position, Apple said "up yours" and ran to court, the ITC, and every other body it could.
"Mommy said no, so I am going to ask Daddy."
Spoilt child, sirrah. Naught but a spoilt child.
Re: Same same
Prove that Moto is trying to discriminate. Seems to me they offer everyone the same terms. Where is your evidence?
Can I run adblock plus on that?
@Mark C Casey
Absolute Rubbish. The single greatest episode of Star Trek ever is "The Void," Voyager 7x15. It defines the "why" behind the Federation, and explains the underlying ethics that came to mean so much to trekkies everywhere.
In The Pale Moonlight is a great example of cynicism and "the need of the many." The Void reminds us that some principles are worth sacrificing everything for. It is for this reason that I prefer Star Trek to Babylon 5 and other such "dark" shows. Even DS9 – dark and gritty by Trek standards – maintained the core values and ethics of the Federation. Call me a dreamer if you must, but I believe in those ideals. "The Void" is, to me, an illustration of why.

Re: Trevor, you need to move in to a first world country away from Canada...
Also - and I double checked - there was a whole damned paragraph about "10GbE on the motherboard." In fact, it was followed by a discussion about the difference between LOM and switch PHY pricing and availability.
Dude, les Q?
Re: Cisco has competition
From experience, you can *flatten* a Supermicro 24-port 10GbE switch, flooding each port with traffic and the damned thing doesn't blink. (Review on that, and a Dell 10GbE switch coming *very* soon.) I know I'll catch hell from a bunch of dark-age scratching-shit-on-walls-with-sticks types, but...
Maybe the make great core switches for people who need to move around terabits at internet cores. I wouldn't know; I don't play there. But damned if I can see a use for them in my datacenter. Give me Dell or Supermicro any day. That's before we even get into arguments about Cisco switches and their world-endingly shitty multicast performance!
Bring on openflow, ladies and gentlemen. It's time to relegate the proprietary switching solutions to the niche they belong to. Cisco may built "better" gear - for specific values of "better - but most people don't need "0 jitter, ultra-low latency, blah, blah, blah." And if they did, they'd buy Arista anyways. Most people just need cheap, bulk throughput.
For that, you need people selling solid non-blocking switches. Not Cisco's cruft. Let the upvotes fly, folks! You know you want to. Your CCNA training demands it!
That depends on a number of things. There is a war brewing between several vendors on 10GbE pricing. It could happen tomorrow. It likely won't happen until Haswell drops. Expect Haswell to ship with 10GbE on the desktop and 1Gbit LOMs on servers to become nonexsistant.
40GbE switching silicon is coming down to the point where you can make serious margin off of it, and QSFP cables are dropping to reasonable rates as well. Switching manufacturers are going to be forced to drop 10GbE prices around the Haswell timeframe – probably with no more than a 6 month lag – if they don't want shops to bulk ignore 10GbE and move directly to 40GbE.
That would be rather disastrous for switch manufacturers, and yields on 100GbE PHYs are still dismal; if everyone moves to 40GbE switch ports, then demand for 100GbE trunking interconnects will skyrocket. They won't be able to meet demand, and can only jack up the price so high before seeing massive pushback.
Until 28nm fab capacity becomes a lot more available – and that is at least 3 years out – then we can't crank out 100GbE switching at the rate we're doing 40GbE today. It just won't be economically feasible.
That means that we need to migrate people to 10GbE sever --> switch interconnects in a big way, leaving 40GbE for top of rack --> core and 100GbE for "folks with more money than sense."
Unfortunately, nobody wants to the first to take a bath on 10GbE margins. The prices are somewhat stable right now, and demand for 10GbE is growing at a fantastic rate. Eventually, someone will cave – my guess is Supermicro – and take the margin hit to drive to cost of 10GbE into the floor. Dell and other vendors won't have any choice but to follow. Intel will drop the silicon prices down to "pittance" levels and Dlink/Netgear/etc will block-shift to 10GbE overnight.
Everyone is leery of 10GbE prices crashing, but they are *far* more afraid of someone dropping 40GbE. The cost of 10GbE silicon is so low right now that they can afford a price war on 10GbE. A price war on 40GbE would cost the entire industry their margins for the next decade.
So…2014 is my guess. I expect that the price war will hit end of this year, beginning of next. By June 2014, we should be able to go out and buy $750 24-port 10Gbase-T Dlink switches. A year after that, we should be seeing 48-port 10Gbase-T switches drop below $1000.

Re: iSCSI not so hard on Linux.
@Simon Hobson as is well known, I disagree with the CLI uber alles crowd. I believe a GUI is agreat for administering. A CLI is great for automating. I administer a test lab, where I change things "to se what happens." I automate production, where it should do Only Pre-Tested Things.
Re: iSCSI not so hard on Linux.
@Rim_Block Interesting thoughts. I note you suggest Intel boards. I've had a miserable history with Intel boards; do you have any direst experience with those models? I suspect there are plenty of good boards that would make a reasonable underpinning for a testlab; gods know I can't have tried them all!
Re; iSCSI on Linux..."easy" is relative. I don't have a lot of trouble with it...but I work with Linux every day. That…and I wrote all the commands I needed down in a text file. :)
I could point you at several Windows sysadmins that do run in to trouble with it. *shrug* There is no good GUI; it holds a lot of folks back. Enough that I would worry about junior admins raised on nothing but Microsoft being able to reliably use the thing.
If, however, you know your Linux…go hard! The iSCSI targets for Linux are mature and stable. Maybe at some point I should do a "how to" for iSCSI on CentOS 6.2. Hmm...
Re: Do your customers mind?....
Slowly coming to an end...I got a whole 9 hours last night!

@Chz My initial response may well have been on the hasty side. (To err is human. To err a lot is what happens when the coffee runs out.) I've reread it again, and I still see him as attempting to berate yours truly into submission. But if I am going to be a douche on the internets, I am going to be a verbose douche that explains himself so you can judge the totality of my douchiness with all the relevant context.
I am, however, sad that the conversation re: "is the expectation of professionalism on the internet a one-way street wherein those who write are expected to maintain a superhuman level of stoicism and those who comment are encouraged to be soulless self-respect stripping piranha-harpies" never got born. I think it has a real impact on what we – as readers of this fine ball of redtop satire – want this site to ultimately be.
Ah well, that's my problem though, eh? I actually worry about the underlying philosophical issues and long term results that are the inevitably born from the choices we make (good and bad) in our interactions with one another today. Ah well, off to write other things…
Re: Do your customers mind?....
@keithpeter totally ad hoc. And we've had a few "disasters." (I.E. primary system caught fire, dead disks, power outage, fibre provider + backhoe, you name it.) In ten years, I've seen a bit of everything.
Fortunately, I am wildly paranoid. Wildly, world-endingly, crazy-like-a-fox paranoid. My file servers are specced and configured to run double duty (in an emergency) as virtual hosts. I have replicated and backed up traffic offsite here, there, everywhere. Certain endpoint systems are bought specifically to match the hardware of the servers in use so that A) the end user has a bitching system as they need for their job and B) in an emergency I can cannibalize it to get a more-critical system up and running.
When I build personal PCs - or PCs for friends/family/etc - they are build to similar specification as those systems built for my customers. That way as these people upgrade their systems - which occurs on a more rapid schedule, generally - I have a steady influx of gently-used parts that can be recertified and put on the shelf as spares for those brown-pants moments.
Every single thing I design or build is designed so that it can – in a pinch – serve any of a half dozen roles. Everything is tested to serve those roles before the first generation hits the ground and some of these systems will be torn out of use (for example as servers) and repurposed (for example as desktops.)
It isn't "proper." It isn't "best practices." But for many of these clients it is the difference between "being able to run a business and not being able to run a business." Doing things according to a whitepaper would bankrupt some of these organisations just to do the upfront costs, that's before we even get into the whole "refresh when the hardware warrantee runs out, or Microsoft releases Yet Another Version."
I sure catch a lot of crap from commenters for talking about such things. (It's blasphemy.) There are a lot of assumptions that because I am forced – yes, forced by necessity, something people can never seem to understand – to work with next to no budget for hardware or software that nothing is redundant or backed up. I think that these folks would be shocked to see exactly how far you can push modern equipment, and exactly how many layers of redundancy you can build into your network just by ensuring that your equipment can serve dual roles if absolutely need be.
I really like the ones who presume I must prefer things this way, or that I am somehow choosing this course. It is s simple matter of "presenting the arguments for more money" they claim; argue and you will get budget. It's not the case. I am generally privy to enough of the financials of these businesses that I know damned well how much money is coming in, where it is going and why.
My job is to make do with what's there until the money is available. It is to reassess the situation every so often and inform the business how close to the red line we are. What is the worst-case scenario? How do we recover from that? What are the risks of the various scenarios coming to pass? What downtime will occur whilst implementing backup plans?
The owners of the company then weigh the options and make the call about who gets how much money that year. So by necessity, everything for these types of folks is ad hoc. It isn't good for one's sanity, maybe…but you do learn rather a lot, very quickly.
And you learn very quickly to understand concepts like "return on investment," "total cost of ownership," "capital expenditure," "operational expenditure" and "operational paranoia" at a truly intuitive level. Every single choice and decision goes through cost, risk analysis, "how many layers of redundancies can we build for that" and many more filters.
It is ad hoc, but a carefully considered, meticulously constructed sort of ad hoc. Layers and layers of it, all interconnected and highly redundant. Fortunately, there looks to be only a couple more years of it until I am finally, mercifully free of the last of it. I can't wait.
Re: I've seen...
"On an unrelated note, scary is seeing a refrigerator-sized core router (with about a mil or two worth of line cards installed in it) being held to the rack by four screws instead of the 8-10 that it preferred. :)"
I am still trying to get pas "a mil or two worth of line cards." Alas...
I don't have a "problem" with IOPS at all. I simply didn't feel it was as relevant in this particular context as it was in others. You'll note that IOPS figures were included and discussed in the Hyper-X review because I felt that in that context, they mattered.
I ran lots of bench marks because I was personally curious. I simply threw things at the unit, collected data and then sat down at the end of it and decided what would make a good article that would appeal to the majority of my intended audience.
That said, for future reference – and as an item I hope you take the time to reflect on – you will not get a writer to "include [x] in their articles" with borderline ad homenim posts. If you take the time to read my interactions with other readers, I think you'll find that I am open to providing information as I can, and even work to include the better suggestions into my articles. (Or write articles on requested topics.)
Most writers don't take well to attempts to berate them into subservience, no matter the technical ability of the individual typing the comments.
I don't disagree that with you at all that the things you talk about are important. You are elucidating critically vital information to convey to the readers, however I believe that the context is inappropriate. The topic at hand is completely inappropriate to include as part of the review of this device; it should be a feature unto itself. "Here be the basics of storage: learn it, motherfuckers" or some such.
I think it is an important topic, and despite the animosity of the presentation, I believe it is worth pitching the features editor for an article later in the year. I will add it to the list.
Re: Trevor.. these are nice boxes, but..
To be honest; it worries me...but less so than it probably should, were I a "proper" storage wonk. The truth is that I don't trust "dual controller" systems as the be-all and end-all of high availability either. Dual PSU, dual controller…but that still leaves a mobo, CPU, RAM and other widgets inside those boxes that are single points of failure.
The lack of real-time block-level replication is the thing that ultimately makes me twitchy.
Even if I were to go out and buy an expensive storage array from EMC, Netapp or otherwise, I wouldn't sleep at night unless everything was backed up. Ultimately, that means block-level replication between two storage devices bonded in a cluster using MPIO against at least two switches into two separate controllers on each relevant host.
And then I will still take backups with something like a Unitrends box. (HA is not backup!)
So what does the lack of a second controller in this circumstance really mean? If it fails you are down. That's a bummer. It is swappable; you can always keep a spare on hand. You could also keep a spare Drobo on hand, and just swap the disks, but that's getting into "byzantine" territory.
So my take on this is "do no use the Drobo for anything that requires HA storage." Also: "make sure you buy a second controller card and keep it on the shelf." For the majority of my workloads, I don't need HA storage. A half-hour's downtime – even at the height of the year – isn't the end of the world. I also keep backups of everything, so even if the whole thing were to vanish in a puff of smoke – a possibility for any storage array, no matter the vendor – I can recover.
I don't have a problem rolling this out to client sites to prove "scratch space" LUNs for creatives. I also have one going into service as the "volume shadow copy" LUN provider for a pair of physical servers on a client site. (That one has no SSDs; it's just a giant box of storage.)
Like any storage, it is a question of fitness for purpose. The lack of a second controller wouldn't bother me if Drobo were to add block-level replication; I'd rather have two completely separate units in lock-step than I would a single unit with various "redundant" bits.
The dual controller part would take Drobo doing some reengineering to solve. Block-level replication could be done with a software update. Until Drobo make that choice, I feel they are locking themselves out of a wider market that would otherwise give them serious consideration.
Re: Windows file copy screen grab
That particular screenie was - I think - pulled from a system doing a "bulk transfer" from a LUN on my Hyper-X array (which goes zoom!) to a LUN on the Drobo. If I read the notes correctly that I took down for that screenie, it was taken as part of a larger test in which - at the time - I was moving 25 VMs from one LUN to the other, and wanted to see how this would affect the stability of the file transfer.
Basically, it tanked the throughput - from 100MB/sec to 35MB/sec – and the throughput became "unstable," fluctuating between 30MB/sec and 50MB/sec. Windows file copy couldn't figure out what to do about judging transfer time on that and flopped around like a fish out of water.
Ultimately, however, it averaged 32Mb/sec over the course of the transfer – measurement taken with a stopwatch and some basic maths – despite the serious hammering the VM nodes were putting the unit through. (I think that 3 of the VMs in the transfer group were undergoing Windows Updates - .net and MSRT – while another one was performing an integrity check on a financials database. I turned Windows' caching off for the test.

@kiethpeter there are several customers using my corporate infrastructure, and yes…most of them are pro bono. I'm not a complete asshole; I try to provide charities, churches, friends, family and so forth with capacity (and even services) when and where I can. The tradeoff is that these services are provided on a "best effort" basis. I am continually attempting to acquire new hardware, software and expertise to ensure that "best effort" is better next week than it was the last.
My infrastructure is also (sometimes) shared by my largest customer; the customer in question reads does in fact read The Register. It isn't always black and white though; when I say they have zero money for IT spend and I mean it. Staffing is covered, but capital spend requires making some tough choices.
Do you refresh your servers/desktops/etc which seem to be doing the job and could be stretched out another two years or do you buy another $industry_specific_widget that could increase your production capacity 10% for the next 2 years, paying itself off and the new IT gear you need, if you can only baby the existing stuff along that little bit farther?
The customer in question chose the second route. I have reservations about it, but ultimately gave the thumbs up as "doable" largely because the IT equipment for my consulting company lives in their datacenter. If the brown stuff hits the rotating air circulation mechanism, then I can spot them spare capacity for long enough to see them though whatever issues arise.
(Does that make me a cloud provider? What kind of cloud? What if it's just "I have spare servers and light things up on hardware? Labels, categories and names, oh my!)
My relationship with the customer is solid; they aren't going to screw me and I am committed to making sure that they have what they need to get the job done. They provide me a rack's worth of space – and the fibre optic internet that goes with it – in their datacenter. In exchange, I make sure that if something goes wrong with their aging, finicky infrastructure it will get fixed, ASAP, even if that means putting my own equipment into play.
The datacenter is 20 ft from my office. Work is 15 minutes (8 at night) from my house. For now, it'll do.
I did a lot more than what ended up in the review. I had the thing for a month and ran a whole barrage of tests. Not all of them were properly recorded, screenshot, etc. (Though many more were than ended up in the article.) A lot of tests - at least initially - were to see where the bottlenecks were, what performance was like...basically to "get a feel for the unit."
The majority of my benchmarking work was done with iometer, sqlio, vdbench, crystal disk mark, passmark's performance test, hdtune pro and window's resource monitor. What came out of the benchmarks was that this device wasn't going to win any IOPS contests.
When writing the article I felt that taking up a page or so with a pile of statistics that can be boiled down to "the performance is okay for the disk loadout, but ultimately is rather middling, and heavily reliant on the tiering to make up the IOPS on the transactional side" was not really a great plan. It wouldn't let me address the other aspects of the unit or discuss the tiering in depth.
I decided that I would include the bits of performance info on the Drobo that I felt most admins likely to buy a Drobo would care about: throughput, not IOPS. My theory – and obviously I was quite wrong about this – was that if anyone was interested in more info, they'd ask. That's what normally happens; people ask questions about extended information in the comments and – assuming I have it – I provide it.
Well, apparently when I am wrong, I am spectacularly wrong.
So what results is ultimately a clash of perception. I perceived – and still do, frankly – Lusty's comments to border on ad homeniem, with a soupcon of "ultimately, you need to buy X product." I didn't – and, rereading his comments I still don't – get "wants to be helpful/educate" from his words. Then again, I am human, I can be – and at least once a day I am – wrong. If so, then Lusty, I apologise.
I don't mind being challenged. I do mind being attacked. There is a difference between a friendly challenge and an ad homenim; my interpretation places Lusty on the wrong side of that line.
My response – while somewhat irritable – was not meant to be "attacking" Lusty in any way. I certainly did – and do – want to explain why things get written as they do, what the choices made were and why they were made. I also wanted to find out what he wanted, what info I could provide him.
So no, I have no problems with someone who wants more information, or would prefer I included X information in an article. Criticism - and believe it or not, I do consider Lusty's comments valid criticism, not mere opinion – helps me determine what to put in future articles. Or, in this case, is putting more emphasis on my need to get a secondary site up where I can post "raw numbers" details for such reviews that I can then link to from a main article.
How one goes about expressing their desires for such information, however, will determine how your requests and thoughts are received by the individual you are addressing. Collectively, we internet denizens seem to have an arrogant opinion of ourselves and a sense of opinionated entitlement that is patently unreal. We demand the #deity-given right to attack writers on the internet personally and professionally yet we take notable umbrage when those same writers should dare to ask "so who exactly are you, and what do you want?"
The writer, we say, should serve as a psychic sink for our own narcissism and desire for personal recognition; they must accept beratement and chastisement from any and all quarters without questioning those who question them. They should accept us – anonymous blobs of text – as experts on all subject matters, especially when we disagree.
Agree with me, we demand, not him or her or them! Be polite to me, writer man, even if I am utter trash to you. This, we call behaving like a professional; a one sided concept as soon as the internet is involved. To be professional on the internet, you see, is to treat even the vilest of anonymous commenters with respect, patience and – preferably – even some fawning adoration. It is – apparently – deeply unprofessional to respond to someone in kind; never challenge the assumptions, motives or tone of the anonymous block of text!
The worst part is…both sides of that particular argument are right. If you bend over backwards and mollycoddle every douchebag on the internets you're going to end up wasting a lot of time and quite possibly killing yourself in a drunken, depressed stupor. The internet is a cyclone of shrieking trolls; many of whom take great delight wasting your time and ruining your day.
By the same token, you do want to be polite, respectful and – dare I say it – professional to as many of these folks as you can. Many of them are decent, hardworking types who are looking to make a contribution to the world and hoping you'll help them do so.
Sorting the shrieking troll (who ultimately is going to be a net drain on your psyche and time) from the indelicate nerd (who ultimately would be a great guy to know personally) is hard. Hard enough that we all get it wrong from time to time.
Reading people, interacting professionally, negotiating, helping and basically doing that "transfer of information in a social context" thing is a hell of a lot easier in person (or even over the phone) than it is in text. You get queues there that you don't in text form. So how things are presented in text makes a huge difference.
Most writers – especially tech writers – refuse to interact with commenters. They won't read the comments to heir own articles and they certainly won't respond. General douchiness of commenters is the biggest cited reason, but "inability to tell if serious, trolling or just horribly socially inept" is the second most frequent one I've heard.
Thus far, I've chosen not to be one of those folks. I've had such positive feedback from many of my readers about the fact that I take the time to answer questions and interact that I have chosen to maintain the practice. It could be that I was wrong to make that choice; I will be giving it serious reconsideration.
I have always taken a "give as good as I get" approach to comments. I have felt that anything else would generally lead to insanity. Commenters are right to expect some respect – and maybe even the benefit of the doubt – from writers. There seems to be distinct disagreement here over whether or not a writer has the "right" to expect the same of their commenters or not.
Is professionalism a one-way street on the internet? If so, then the other tech writers are correct and I have been wrong all this time: I should never answer comments at all. Nobody can reasonably be expected to maintain absolute decorum while being the psychic whipping boy for 7 million readers who are not held – externally or by the community to which they belong – to any similar standard.
The whole topic is – obviously – something I've given a lot of thought to. Beyond the traditional commenttard "you've got problems" response - trotted out by the internet's most brilliant minds whenever something is discussed in depth - I am interested in the thoughts and feedback of all and sundry regarding the above.
Re: Linux is scalable performance wise and also financially
Do you have much experience with open source "clouds?" I have some (limited) experience with KVM, and have been tasked to explore both Openstack and Cloudstack this year. I have never delved into open source virtualisation that wasn't a bought-and-paid-for KVM setup with the RH managment tools. (Almost always managed by Puppet.) Most of my "cloud" experience thus far is Microsoft and VMware, with a smattering of Citrix.
Are there thoughts/experiences/considerations beyond what you've posted already you could share wiht those of us who are taking a nose-first plunge into this in 2013?
Thanks in advance...
Re: Linux is scalable performance wise and also financially
Eadon; I can't say I particularly disagree with your comment...but I wonder at it's applicability? Yes, licensing regarding virtualisation and "cloud" sucks. We could have whole long wankfest about how much we mutually think Microsoft is screwing the pooch on VDI licensing, as one example.
That said, I don't see how "open source' is a solution to "need to form a group of specialists into a team that actually works together instead of trying to shank eachother." Even with open source blue crystals, you need storage admins, VM admins, general OS admins, app admins and so forth. Nobody can know "all of IT." Not proprietary, nor open source.
So is your comment simply a result of "see cloud in article, post licensing rant" – perfectly understandable if so – or are you attempting to say that open source somehow mitigates (or eliminates?) the need for specialists working in a team?
Honestly curious as to your meaning. If the latter intent, do you know of any individuals practicing as "open source cloud generalists" at anything other than hobby scale? Where they do "all the things?" If so, please get them to e-mail me. I want to interview them. And learn. Lots.

"irony flying past your head"
Irony. Flying. Flying irony. Well, if it flies, I would presume it could do so over my head. But how does irony fly?
I am confused.
@07:38 Funny, I seem to get along fine with folks that actually say things which are constructive. It's the ones who just want to emote and self-promote that I rather enjoy mixing it up with. Constructive is good; plenty of them around here I rather like.
