Disk areal density: Not a constant, consistent platter

Nate Amsden
Bronze badge

Re: Doesn't everyone who works in storage know this?

Maybe I'm missing something here but one revolution of a platter on the outside tracks will pass over a ton more bits than the inside tracks(more surface area), I don't think it has much to do with how dense it is, I suppose density could play a role if the inner tracks were much more dense than outer but the gist from the article I get is they don't have that much control over it, some tracks are dense others are not sounds kind of random.

I lay my 3PAR storage out the opposite way, new data goes to the inner tracks and work their way out, to sort of ease the burden of a system as it fills up, or something.

Hate sf

SF sucks. Well I guess all big cities suck to me anyway. I live near SF airport and have been to SF 3 times this year (two of which were to meet people from out of country). I hate every aspect of the city. Though SF is not alone same goes for Seattle(lived near there for a decade). Theres two places I like in seattle, hate the rest.

I cant think of a single place worth visiting in SF that would make up for the otherwise horrible experience being there.

I drove to orange county this mornin just missed the rain. My UPS said I had a 21 min outage this mornin but the batteries held up.

just look at the DSL market

for an example of the title 2 stuff right.. Lots of folks seem to want title 2 applied to cable companies, when they already have title 2 providers in their area in the form of DSL. But DSL is "too slow" so they don't want to use it.

I suspect the same will happen to cable(over time) if they go that route.

I don't care too much either way myself my internet usage is pretty minimal these days.

GTA V is a blast

I haven't been much into games in nearly 15 years, but GTA V caught my eye last year (had never really played any GTA before), I really liked the open world it seemed to portray. When I saw that an enhanced version was coming for the next gen consoles it was enough for me to buy a GTA V+PS4 bundle a couple weeks ago. It's been quite fun to play. The flexibility is pretty amazing to me anyway, the visuals are stunning.

I still suck badly at the game, but have had a lot of fun exploring and causing mayhem.

Also got the PS4 for that game demo P.T. which I heard was pretty good. though when I tried it I got a headache pretty quick and had to stop, maybe the motion wasn't smooth enough, and/or I'm old. Tried playing my old FPS games like original Unreal Tournament a couple years ago and had to stop after a few minutes because of headaches, used to be able to play them for hours on end w/o issue.

Another lick of Lollipop: Google updates latest Android to 5.0.1

Nate Amsden

eh

I've kept wifi off on my note 3 to prevent it from getting the latest kitkat update from AT&T. I'm too afraid it's going to break shit(especially since restoring from backup or rolling the update back seems non trivial if not impossible unless the device is rooted etc which mine is not). for 5.0 I see absolutely nothing remotely interesting to me.

OS updates on mobile seem so hit and miss. Really there was nothing worthwhile in the android 4.3->4.4 update for me anyway on Note 3. Maybe I'm just getting old.

POP3 can be configured to leave mail on a server, likewise IMAP4 I believe can be configured to delete mail from a server too(though this use case is probably really rare).

Feds dig up law from 1789 to demand Apple, Google decrypt smartphones, slabs

still have a backdoor though right?

for IOS anyways from what I've read it seems the contents on the phone are encrypted, but contents stored in icloud are not encrypted in the same manor so if the data happens to be in icloud (or in google equivalent) then perhaps apple/google could provide *that* data, just not the data on the handset itself..

me, I don't plan to encrypt, hell I'm still pissed off I have to assign a pass code to unlock my phone in order to install a SSL CA for one of my personal services. Have never lost or had a phone stolen, and worst case there really isn't too much of value/secrets on my phone. Oh maybe you can use my corporate email, big whoop! I could have IT change my password pretty quick.

Much more important to me is more the work it would take to get a new phone, put my data back on it, customize it etc....

Re: Differences from virtualisation?

one major one in my experience is networking. In my experience deploying LXC it seemed not practical to have multiple network segments (and thus routing tables) existing on a host that has LXC. So for example we have our nonproduction VMs on one VLAN and production on another, both have different default gateways(IPs on the switches). In my testing I was not able to have both co-exist on a single LXC host. I read that it *might* be possible at the time(6 months ago on Ubuntu 12.04) but highly experimental and complex, so I decided to not even bother as those two things are not something I am interested in trying to support.

Another difference is fully abstracted isolation in a VM vs container which gives you things like VM mobility between storage and servers w/o downtime - at least I haven't seen this happen with containers of any type.

We have deployed 6 containers(across 3 LXC hosts) for a very specific production workload (all are load balanced running the same application stack). I could see us expanding container support in very specific production workloads in the future to better leverage the hardware, though I don't see a point in using it for non production stuff as it is not flexible enough(routing tables) and our non production stuff isn't redundant since it is non prod, so a failure would be more of a pain to deal with if it can't be transparently recovered, also scheduled downtime(e.g. kernel update since there is only 1 kernel across all containers on a given host) would be a pain as well for the same reason.

I also do not like how I cannot query CPU/memory usage on a per container basis using regular linux tools they are not container aware (there may be tools that can get this info I haven't seen them myself). Same goes for network traffic - if I query SNMP on a linux container for network data I get 0 data. Also do not like how the LXC "parent" host shows all of the PIDs from all of the containers, makes it very difficult to sort through things. For us it is manageable since the workloads are very specific but I wouldn't want to deploy a dozen different random containers on a host that weren't tightly controlled for this reason too.

Since deploying containers, aside from the annoying things from a management perspective they have been flawless and have served their original purpose - unlock a massive amount of CPU(24 cores (48 threads) x Xeon E5-2695v2 per host) for our main e-commerce platform in production that comes with a $15k/server/year license. Average CPU went from ~40% to about 3%(new systems have much more horsepower than previous VMs). Peak CPU hasn't gone above about 25%, so these have a good 2 or 3 years of growth for them I bet, which was the plan. Massively under subscribed most of the time but that's fine - the cost of the license alone justifies that easily, as does knowing we'll not run out of capacity on that application for a VERY long time under any circumstances.

Unlike some orgs we are not one of the ones that likes to destroy and re-create resources on a regular basis. These containers will have a life span measured in years, like our VMs, ideally anyway.

don't trust mobile period

I don't do any online banking, any e-commerce transactions (outside of google play store for a few apps, no movies/music/whatever else they have) on my mobile devices (all Android Samsung Note 3 and Toshiba tablet though I wouldn't do it on IOS either).

I am very very cautious not to install any privacy invading applications either.

anything that needs security gets done on my linux laptop.

exception is I do occasionally login to work VPN from my phone.

in general I think the risk is quite low for me, but I don't do it anyway. There's never been a time where I felt "I have to do this *now* (and can't wait till I get to my own computer)"

also maybe goes without saying I don't use public wifi hotspots (except the very occasional hotel but that is rare I prefer to use my phone's mifi which I pay $50/mo for already).

729 teraflops, 71,000-core Super cost just US$5,500 to build

absolutely, nail on the head there.

this "super computer" didn't cost $5,500 to build, it cost $5,500 to rent. big difference(duh). Obviously 99.9%+ of the workloads out there aren't suited to one off runs of a few hours never to be needed again..

You've been able to "rent" super computer time for a long time, no news here.

This is one of the very very few good use cases of public cloud computing (IaaS anyway - SaaS is a good model, PaaS not sold on either).

Russian internet traffic detours through China's Frankfurt outpost

Nate Amsden
Bronze badge

Re: Not that uncommon

this is my own personal favorite traceroute - from just over 10 years ago, ISPs claimed a fiber broke in the eastern US which caused routes to fail over and opened a hole in which russian ISP(s) were able to advertise for our IP space(no idea if intentional or not), resulting in some ISPs routing to russia before getting to us resulting in excess of 95% packet loss. Sometimes the routes would bounce back to normal.

Took AT&T (our ISP) and friends a good 8-9 hours to get it fixed(I assume by installing route filters or something). Due to the packet loss we had to shut our website down for several hours.

As soon as the packets hit Russian routers the packet loss went from around 0 to more than 40% and higher from there.

http://elreg.nateamsden.com/funkyroute.txt

That is a traceroute that in theory only should go about 30 miles from source to destination(my apartment to my company's colo), instead - 32 hops, 200ms+ and 98% packet loss.

Wipro uses Nexenta to blast its way out of the hardware prison

Nate Amsden
Bronze badge

purchase price is not the full cost

Of course, having used Nexenta for the past couple of years in a very limited role I would never ever deploy it to true mission critical, wouldn't even consider it.

Big IT firms buy things lightly all the time, they have the budget to do so, they can buy something, have it work or not work,toss it out and go to something else.

As for data integrity on ZFS - it probably works great when there are no issues, once you get data corruption(as I had several times with Nexenta - due to their clustering software messing up) you are SOL. The diagnostic/repair tools for zfs for such a situation are basically useless. Even something as simple as say "zero out the corrupt data and fsck the file system so at least it mounts cleanly without panicing the Opensolaris kernel resulting in an automatic reboot" (something I've done with linux on one or two occasions w/ease) wasn't possible at the time (about 1.5 years ago). Support said "restore from backup". I didn't care too much about the data that was lost I just didn't want to have to rebuild the entire file systems, there didn't seem to be a way around it though. I spent hours with the zfs repair tools to no avail (at some points it seemed like it would work then after some time it would panic again).

Nexenta also tries to do too much for a small company, too many features makes me nervous in general. For us we were using only a few of the most basic ones(mainly I was using it as a NFS platform(for under 1TB of data) because it supported snapshots and high availability -- until we turned the HA off to stabilize the system). Oh and don't try to click on the snapshots in the GUI, it will spin for about 75 minutes before timing out because it is iterating through each and every snapshot on the system in serial to get info on it (yes the Nexenta software we have is old, I refuse to update it until we are migrated off out of fear it will break more, at least the issues we have now are known and I can fix them if they come up - support was useless)

Nexenta is not much more than a toy for white box system builders to be able to say "hey we do storage cheaper than the big guys!". For that they do it well, not a solution I'm in the market for anyway.

I'm sure it can work for some folks, I feel sorry for anyone being forced into using it for an important project though - you get what you (don't) pay for. Storage is complicated, storage is generally pretty fragile (unlike networking which is generally stateless), it's hard to get right, it's not cheap to get right. Cutting corners will likely cost you more in the end (or maybe you'll be lucky and not be impacted).

HP gives StoreServ a speed boost with flashy cachey spit'n'polish

Nate Amsden
Bronze badge

Re: Avoid at all costs

I just got my 7450 installed last week and upgraded to 3.2.1 MU1 (as far as I can tell that is the first release that supports dedupe and it is *brand* new (the ISO on HP's ftp site is dated Oct 30).

http://h20565.www2.hp.com/portal/site/hpsc/template.BINARYPORTLET/public/kb/docDisplay/resource.process/?spf_p.tpst=kbDocDisplay_ws_BI&spf_p.rid_kbDocDisplay=docDisplayResURL&javax.portlet.begCacheTok=com.vignette.cachetoken&spf_p.rst_kbDocDisplay=wsrp-resourceState%3DdocId%253Demr_na-c04491766-1%257CdocLocale%253Den_US&javax.portlet.endCacheTok=com.vignette.cachetoken

from the PDF

"After upgrading to HP 3PAR OS 3.2.1 MU1, customers with an SSD CPG can provision TDVVs(Thinly Deduped Virtual Volume)."

the 3.2.1 release notes don't mention dedupe, only 3.2.1 MU1 (above link has release notes for both versions in one PDF)

So find it kind of hard to believe you've had much time to test dedupe at this point. Dedupe would obviously get it's best value on something like VDI (never used VDI myself and don't foresee that changing anytime soon).

As a customer since 2006 I have been very happy, even more so to have such a mature platform offering all flash and dedupe etc.. The initial footprint of our 7450 (4-node) can fit almost 200TB of raw flash alone (that is assuming they don't release larger drives in the future which I'm sure they will have larger drives). Cost was really good too. Even if there is no dedupe it will pay for itself quite easily in performance and scalability.

I exchanged a couple emails with a friend of mine who works at Pure Storage (who used to work at 3PAR) and he said they do get beaten by 3PAR on price (not on data reduction - 3PAR doesn't support compression yet). Just hearing 3PAR beating someone (esp a smaller player) on price is just foreign to me. Most of it comes down to the very large SSDs and how they can get much lower $/GB as a result.

I don't have anything yet connected to my 7450, been busy configuring new vmware servers and other things -- but in the next few days will be storage vmotioning 1-200 VMs over to it. I don't expect much savings from dedupe until we move some databases over. Short term it's just playing around with it, see how it runs, probably won't have time to move much production stuff on it until our holiday "freeze" starts at the end of next week.

I have never used AO -- never really liked the concept of sub LUN tiering(on any platform was never sold on it), I always wanted to see a real array-based flash cache(that can cache writes), and it seems now after 5+ years of me pleading for it they are getting closer.. caching reads on a 90% write workload isn't going to do shit for me.

Re: New partner?

seems like a fairly typical article. I don't see any opinion in it saying "oh go buy this it is better than the rest". They are just reporting on what the vendor is announcing, El reg has been doing that for as long as I can remember (been a reader for about 14 years now though my memory doesn't go that far back).

El reg does seem to favor sponsors though I suppose is understandable. One vendor I use for networking doesn't get mentioned much here in articles, after speaking with the vendor's PR folks (who do send info out to network oriented sites) speculated it is because they do not advertise on el reg.

Fujitsu's ETERNUS CD10000: Better Ceph than sorry?

Nate Amsden
Bronze badge

why

why would you want to risk storage by running workloads on a storage system? It's not like your going to benefit from ultra low latency on such a system it's distributed object storage. Even if you did benefit, spend the extra $ and get dedicated compute hardware, keep them separate.

my VAR has latched onto the idea of Cleversafe back end + Avere front end(NAS + tiering/caching) which seems to be an interesting combination. I have warned him against Ceph, not mature enough for most customers out there. (Not sure how much better Cleversafe is but they do seem to be the market leader so that says something at least). I believe Ceph has NAS as well but that's another thing I wouldn't put much trust in at this stage of their game.

I'm not in the market for such a system and don't imagine that changing in the next 2-3 years anyway.

Re: US will still get your data

Even if they do win, the threat of having future rulings overturned etc will probably always be there. So if your concerned about such a thing, no point in even considering such a cloud company. You can encrypt a lot of your data, but obviously most active data has to be in a decrypted state in some form to be read(I suppose one exception is if your doing nothing but storing and retrieving encrypted data and decrypting it off of the cloud for reading -- in which case this new data center buys you nothing new from a security standpoint)

Re: VM Migration

I remember about 4 years ago I met with the head of EC2 and their chief scientist (the head of EC2 was the brother of the CEO of the company I was at at the time). We vented our frustrations with their platform (it wasn't the first time my boss met with them to say how unhappy he was as a customer). And they acknowledged the problems (but never fixed most of them likely to this day).

ANYWAY the topic of vmotion came up in the discussion and they said "oh well when you move a VM you get a spike in latency for a few seconds, we don't want our customers to endure that so we don't have it" (I think that was more of a cheap excuse because they probably weren't technically able to do it due to the outdated and hacked Xen that they had(and probably still have).

As a customer I'd be more than happy to endure some latency during a VM migration if it means avoiding hard downtime of that VM, easy choice to make.

Moved my company out of ec2 cloud about 3 years ago, I couldn't help but laugh when about a year afterwards a developer was doing something and I asked them why (I forget what they were doing) and they said they were doing that in case we had to rebuild a server (not too uncommon in public cloud). I laughed, to this day 3 years later we have not had to rebuild a server for any reason.

lots of apps have single points of failure, not everything is a stateless web server. One of my big arguments against such cloud providers is just that -- most developers don't build for that, even dozens of ones I have worked with who built their apps from the ground up in cloud environments. It's simply not a priority. It makes sense to me anyway, you have to choose building features for the users or making the app really robust, I'd wager greater than 95% of orgs choose the former(in all of the "web" startups I've worked at the past 15 years that number is 100%). Only when the latter becomes really really painful do most orgs invest in that(yet to work for a company that did this) because it's quite complicated to get right, and in many cases it is simpler/more cost effective to provide higher levels of availability in the infrastructure than it is in the app (that usually flips around when you get to really large scale (systems numbering in the thousands at least) -- but most orgs aren't at that scale and never will be).

most management types see cloud and think of it as a utility that it'll never go down, some magical thing that just works.... there's a ton of work that has to be done to leverage such cloud providers properly and most folks never get around to doing it. Certainly was never, and is not worth the effort for my org, or any company I have worked for in the past, the return on the effort is simply not worth it with all the other compromises (both in cost and tech) that must be made to make things work.

There are 1.6TB SSDs in the enterprise space (seem to be starting in the $2-3k range)

I imagine 2TB SSDs will come when they are more cost effective for the consumer space. Right now it seems a 1TB runs well north of $500 it seems like, so perhaps when 2TB can be sold in that price band it will come.

for one supply and demand, if flash was so cheap people would be buying flash and not disk, and there is not enough capacity in the world to come close to being able to satisfy anything remotely resembling that demand.

two, the cost of spinning rust has always been going down and continues to do so. I don't understand the logic behind flash is getting cheaper so it should be cheaper than spinning rust(which is getting cheaper too).

Flash has a lot of precision involved as well, just look to the massive quality issues on many of the lesser brands over recent years. Just ask Samsung how much it cost them to develop their 3D NAND technology, probably wasn't cheap (my laptop has a 850 Pro in it, so far averaging 1TB/writes/month over the first two months of usage).

None of the companies ive worked at the past 15 years were in a position to do such a move. VMs or server lives are measured in years. It is not difficult to repair a failed one. In fact we have not had to rebuild a single VM since we left amazons shit cloud 3 years ago. VM failures are very rare. Ive seen maybe 4 in 3 years all fixed with power cycling the VM (kernel panic or something). One VM host panic in 8 years of using ESX.

Cloud is mostly hype the amount of effort required to do it right is absolutely huge, and for most orgs a waste of time because they arent to that kind of scale and probably will never be (be realistic!).

Sure it sounds cool, but ill argue till im purple that utility computing fits the needs better than true cloud in greater than 90% of orgs. But utility computing is not hip.

All of the companies I have worked at have been web style startups. Current one and prev one built on cloud (badly). First one collapsed. Current one moved out 3 years ago and even if you toss out the cost savings the improved functionality flexibility performance and avaulability reign supreme.

Greedy datagrabs, crap security will KILL the Internet of Thingies

i don't care about IoT

I'm more concerned about the "smart grid".

IoT is easy to secure, just don't connect the damn things(i.e. don't use them), smart grid is likely to be forced upon us whether we want it or not (at least that seems to be the trend anyway). I am not concerned about someone "hacking" into the power in my apartment, much more concerned, no matter how "secure" the technology claims to be that bad stuff can feed back to the power sources or distribution centers and get them to shut down(or worse).

'I went from a two-hour commute to a 10-min scooter ride by the sea'

Nate Amsden

expensive I think

One of my friends lived there and worked there for some time(and is 1/3rd bermudian or whatever they are called), one bit he gave me is assume each bag of groceries will cost you $100. The salary one gig there was offering me seemed tempting until my friend told me about the cost of living.

My commute is a 20 minute walk (used to be 10 minutes before the company moved further away, new office has a long lease so won't be going anywhere anytime soon) in the bay area. One company I was at four years ago(in WA state) the walk was literally about 500 feet(across the street). I had co-workers who parked further away than I lived. I was so overjoyed when they said come in to the interview and it wasn't until that point that I realized how close they actually were to me (I knew they were close, just not across the street!)

Some people have asked me if I get called all the time because I am so close, I have not. Perhaps twice in the past 3 years.

It's nice to be able to work from home in the morning and then get to the office around noon (I only go to the office because I want to, not because I need/have to).

It's one of the reasons I don't even talk to the companies that try to recruit me(seems like 2-3x/week), quality of life is too high, I don't want to be in a pressure situation where some other company is trying to pressure me to leave because I went down the interview path with them etc.. Nice to feel loved though :)

I had a 1+ hr commute once 14 years ago, lasted about two months before I moved closer to work (down to a 3 minute drive in that situation). Just can't put up with that kind of shit, I suppose maybe I could if it was just driving a long distance w/no traffic.

Iron out the kinks and all-flash servers just might have a future

Nate Amsden

not sure

I understand the point of this article. The kinks are in large part why my systems still run SAN (and disk less -- boot form SAN too). I don't see this changing in the next 1-2 years anyway.

Lots of companies out there have been trying to integrate the server side end with arrays, it's not easy to do, and gets almost exponentially harder when dealing with writes and clustering. That's a lot of logic required, a lot of complexity.

I was pretty excited when Qlogic announced their Mt Rainier technology mainly because they said they were going to offer cached writes too. My workload is 90% write from a storage perspective, so stuffing ssds in the systems for read caches isn't going to do crap.

For a while at least my talks with QL didn't get too far and they did not have the write caching ready yet (with no ETA at the time this was 1-2 years ago). Looking now it's hard to tell if that is done yet or not(they still talk about it in their documentation), and in any case I'd feel most comfortable deploying something like that if it had support from the SAN vendor as well (array based snapshots data consistency etc).

But for me, at least for now it is a moot point, my all flash 3PAR 7450 arrives in a couple of weeks and that will allow our systems to scale nicely, without having to worry about complex sophisticated clustering software on the hosts to offset the performance penalty of using spinning rust. Our data sets are small and are not growing very quickly.

So, people have been working on this for years already.....

No tiles, no NAP – next Windows for data centre looks promising

hate powershell

Haven't used it much but dislike the object oriented-ness behind it. I understand it's mainly because windows is just a big bunch of binaries...

"Growing up" in the linux world for the past 20 years I latched on to the "strings" based approach for scripting, never had much/any interest in object level stuff. Totally different line of thinking. I have a few scripts that use really basic objects but if you look at the 10s of thousands of lines of scripts I've written less than probably 0.1% of them have anything to do with objects. I don't see that changing, so I don't see myself ever really using powershell. Not that it is a big deal since windows is not an area of interest to me.

Of course with Linux with some things you can work with objects if you please (perl etc), though likely most underlying system components still are string based (maybe with systemd that will change, haven't looked at systemd, trying not to think about it, likely won't have to deal with it for another couple of years).

As a very casual user of windows (I manage about 15 windows servers and around 600 linux systems) I am not fond of the new UI in windows 2012 (I've yet to use windows 8, and maybe if I'm lucky I never will, windows 7 works ok). Once I install classic shell it is a bit better.. Our usage of windows is pretty unsophisticated so I'm sure we are not leveraging any of the new fancy features of 2012 (outside of 2012 storage server clustering which is our new low end NAS platform which I have been fighting with known MS bugs for the past 4 months working with HP support on, they basically say known issue, MS is not going to fix it and even if they did it'll take forever so use this workaround instead).

The thing I dislike most about the UI in 2012 anyway(other than metro) is how the automatic update prompt just consumes the whole screen, like it's punching you in the face to read the message, really terrible. Maybe for a consumer OS, not for a server OS. Keep it to the system tray, and maybe have a little bubble pop up out of the system tray icon to remind you.

An EMC-HP Borg cube will totally ANNIHILATE its storage worlds

Re: Misunderstanding

While StoreAll is a scale out filer it does not compete with Isilon. HP re positioned it as an archive platform. Its not geared towards the same market as Isilon (HP used to try to sell it that way but it didn't work).

StoreEasy may be their scale out filer for transactional workloads. Up to 8 controllers I believe and windows 2012 storage server software. Having used it for the past few months I am not too fond of it.

StoreAll is also what powers they underlying storage of StoreOnce.

HP offers helion openstack (downloadable) for the virtualization standpoint.

I think hp data protector should go on that list perhaps next to avamar.

HP arcsight and tipping point are both security products
