Xen sticks pin in bug behind Rackspace GLOBAL CLOUD REBOOT

Re: I can see why you would simply patch the VM

because these public clouds suck ass & do not support live migration in many cases even though the tech has been available for over a decade now (just checked VMware vmotion anyway came out no later than 2004)

Balls of destruction CRUSH your fancy new storage systems ... better get used to it

Nate Amsden

design it right

And you may not have an issue. HP recently came out and claimed there has never been a software update that required data migration on 3PAR ever. I do recall being told there have been I believe two 3PAR updates (a looooong time ago certainly before I was a customer in 2006) which required some degree of hard downtime, but no data loss/migration. The end to end virtualization of the platform means data migrations, if needed should be able to be done on the fly. You're not dealing with disks after all but virtualized chunklets. Simply replicate from one format to another and flip the switch (this technology has already been on the platform for many years it's how they convert between RAID levels and move volumes between tiers - totally non disruptive).

On the topic of upgrades, just about 3 weeks ago I did a minor software upgrade on my dual controller 3PAR platform - first node upgraded fine, 2nd node failed halfway through (internal disk on the controller failed). System was in a degraded state for a long time, as support struggled to try to get the new controller to join with the existing one with mismatched code revs. Eventually once I got the case escalated to engineering they figured out a way to do it. Performance was not good during this time of course, made worse by our 90% write workload. I had been trying to get a 4-controller system in for many years but they company didn't want to pay for it originally. Our new all SSD platform which I just submitted the order to yesterday is 4 controller though (nothing to do with recent upgrade this was approved 10 months ago). So, will be nice to be on a 4-node 3PAR platform once again. It doesn't solve world hunger but really makes me not want to even consider an architecture that can't go beyond 2 nodes in a unified cluster (e.g. I don't view NetApp clustering as real clustering it's more like a workgroup of systems that you can move volumes inbetween similar to how you can move VMs between vmware hosts, but you can't have a single VM span more than one VM host)

http://www.techopsguys.com/wp-content/uploads/2010/08/cache-degraded.png

(unlike many 3PAR software features that one is included at no charge)

Public cloud migrations are of course generally far, far worse. They would often go something like "you have 30 days to move your data before we delete it - oh yeah and we don't offer you support or help you should know how to do this".

Oracle crashes all-flash bash: Behold, our hybrid FS1 arrays

Nate Amsden
Bronze badge

maybe someone will actually buy this

I was told a while back that a former Pillar sales rep was brought back to Oracle -- to sell Pillar to internal Oracle users/groups. NOBODY wanted the tech, not even inside Oracle themselves!

On paper this seems ok, but really don't see any reason to give Oracle consideration for serious storage (outside I guess of their engineered systems if I was in the market for such a system). The capabilities of this new system seem like they are playing catch up for the past ~6+ years of being MIA - which is fine, but just means more than anything else the platform is not mature, and won't be for a while.

Re: ODMs.

I don't know about you but I was running linux in a mission critical role (RHEL AS 2.1 if I recall right and before that it was "Red Hat 7" I want to say, before RHEL existed RHEL 2.1 was a simple migration basically the same software if I remember right) back in 2003 in a datacenter for mobile e-commerce transactions(easily a half million $/day I think in sales in the early days). Wasn't native linux code but rather a combination of Tomcat, BEA Weblogic on Linux, and Oracle back end on HPUX (PA-RISC then Itanium) with EMC then HDS storage at the time.

I don't miss having to hack kickstart install discs to get compatible network drivers inserted into them so we could install our systems, stupid broadcom. Though a few years later intel e1000 went down the tubes(drivers changing constantly in incompatible ways) too.

I remember deploying my first VMware in production (GSX 3.0 if I recall right) I want to say in 2004, same application stack. Was an interesting weekend, last minute deployment to try to save the company's reputation because of bugs in their software. After working 50 hours over 3 days (most of that configuring the in house application stack) it worked, and everyone loved it.

ODMs do well for cloud folks I suppose but the lack of support/poor quality makes them a poor choice for most folks out there. Not everyone has the time to babysit the systems and write custom code to keep the HW running. I did one fairly decent scale white box deployment back in 2005(cost was the main driving factor), and well I was glad when I got to use HP Proliant again. You certainly do pay more, but you get a lot more too. I love ILO4 (even more than ILO3) - the KVM remote console is SO FAST now, email alerting for system events/failures/etc.

Firmware updates are painless too. My personal supermicro server's remote KVM management card has been offline for months because the last update required I wipe it's configuration and I haven't gone back on site to re-configure it yet. Yeah - not for serious business use. OK for personal use.

Oracle: What's the X4-4? In-memory monster slams jaws down on 3TB, for starters

Nate Amsden
Bronze badge

but how fast is it?

and how scalable I suppose..

Last week HP Vertica was boasting how facebook uses their platform to ingest 35 TB/hour (15GBytes/sec) of new data in a 4PB rolling data set, all without losing more than 20% of query performance for the clients.

Vertica architecture says SSDs don't really help performance since their sequential data rates aren't much more than spinning media.

Is your data growing too big to handle?

Nate Amsden
Bronze badge

ceph is not an alternative

object based storage has it's use cases, but low latency transactional workloads is not one of them.

"Another interesting way to deal with the problem is to stop thinking about hot-spare hard drives and start thinking about hot-spare reserved disk capacity"

As a 3PAR customer for 8 years now, having said 'distributed RAID' and 'hot spare capacity per disk' for 8 years now, "start thinking" seems kind of late !

"That is because when you spread the data over a large number of disk drives, it becomes statistically more likely that another participating disk will fail during the rebuild."

I suppose that really depends on the architecture. I don't believe this is the case in 3PAR, I'd say there is far less chance of a 2nd disk failure impacting the system given the short rebuild times. If your rebuild time is taking many hours (or days) then the risk is much higher, if taking only a few hours, not so much.

I wrote more on this topic four years ago here: http://www.techopsguys.com/2010/08/13/do-you-really-need-raid-6/

Of course that mainly applies to "sudden" disk failures which are typically rare in fancy storage systems that have abilities to proactively detect if a disk is going bad and stop using it. There is one disk in one of my arrays that has had 3 errors on it, if it gets to a 4th the system will stop using it (data from the 3 errors has been relocated elsewhere), it's been at 3 for several months now though.

and while I'm here, showing 81,000 micro raid arrays on a storage system I had at the time: http://www.techopsguys.com/2009/11/24/81000-raid-arrays/

DDN has built a lot of their systems to assume you can take hard downtime for system maintenance, not something I'd pick for high availability. Good for batch jobs HPC type things where there are periods when the cluster is in between jobs and the storage can be taken offline.

My new all-flash system has 4 storage controllers, so performance doesn't degrade (nearly as much) as if it only had two (90%+ of the cache on the controllers are dedicated to optimizing writes to the back end SSDs, so cache mirroring is still very much a factor in the all SSD world if you want optimal performance and efficient operation).

Hackers thrash Bash Shellshock bug: World races to cover hole

Nate Amsden
Bronze badge

overblown

as usual, same as heartbleed. The article is written as if every system that runs bash has cgi scripts (or other) that call bash. I'm sure there is a bunch, but really in general overblown.

Wake me up perhaps when the tcp/ip stack of linux is remotely exploitable somehow with some weird packets? The way this article was written it is like the world was coming to an end. Maybe I'm just getting old but I don't see it happening, at least not with this security issue, for the most part this is script kiddie stuff.

Those that are most vulnerable are probably the ones least likely to upgrade (unmaintained/unmanaged servers etc).

SQL Slammer was pretty neat in that after what 4-6 hours it had spread around the internet?

I upgraded my bash anyway but struggle hard to think of anything in my environments that would call it in a vulnerable way.

Linux? Bah! Red Hat has its eye on the CLOUD – and it wants to own it

Nate Amsden
Bronze badge

HP disagrees

Maybe not officially I suppose but some folks I talked to on the side said while Red Hat wants to be the leader, Openstack is a different beast from Linux, and they don't believe at least that Red Hat has the resources to do it (right) in part because there's a lot of integration work needed at the hardware level.

I remember when Red hat touted they were the #1 contributor to openstack (and had recently suprassed Rackspace at the time I believe - a year or 18 months ago I forget), now HP is the #1 contributor, though you could say almost neck and neck with redhat (http://stackalytics.com/). I don't track Openstack closely just had to look it up.

HP thinks they will remain the king of open stack, I suppose time will tell.

What's this 'pay as you go' cloud crap? Dunno about you, but my apps don't work that way

Nate Amsden
Bronze badge

I don't know how

with a straight face you can reccomend someone develop something on top of amazon while at the same time saying "pay for what you provision" is bad. Amazon practically created that whole thing, and it's been a disaster from the start. Their model is so incredibly broken it's sickening. There are some services they offer that are pay for what you use (S3 and a few others that I can't name off the top of my head). But their EC2/RDS/etc type services are all not only functionally terrible, but the pay for provision model is just bad bad bad.

I can't speak to google/azure services I have never used them.

There was a video presentation I saw of a guy at a conference a few months ago:

http://vimeo.com/95066828

He talked about all sorts of concepts whether it was cloud, nosql, security etc. On the clould front he said there were two types of people:

1) people that have actually implemented cloud services

and

2) other

It is quite funny and he manages to nail so many good points while keeping the audience entertained, it's hard to get me to laugh out loud but he did it on all of the times I have re-watched that video.

NetApp's running with the big dogs: All-flash FlashRay hits the street

Nate Amsden
Bronze badge

seems like they were forced

to release it before it was ready, kind of sad I suppose. Given it took them what 4-5 years to integrate the spinmaker(?) stuff might it take a similar amount of time to make a bulletproof all SSD platform? Obviously an all-SSD Ontap platform doesn't cut it or they wouldn't of built Flashray. I mean even a soft launch with only one controller is just shocking. I can imagine beta testers etc using 1 controller but it is shocking to do any sort of public release controlled or not that doesn't even have dual controllers.

This and the recent EMC upgrade issues with XtremeIO makes me happy I stuck with 3PAR 7450 for my all flash workload - low cost, high performance, and bulletproof (normally you're only supposed to be able to pick two of any three!). My 7450 is just a bare bones system though it has 27TB raw flash just to start, expandable to over 180TB raw flash with current SSD sizes without adding any disk shelves, or roughly 500T flash with adding some shelves.

No way in hell would I trust Skyera for my mission critical several hundred million dollar/year transactional businesses - not for a good while anyway. Their tech looks interesting, they need a lot more time to demonstrate they have a solid/stable platform though (same applies to any storage startup not them specifically).

A SCORCHIO fatboy SSD: Samsung SSD850 PRO 3D V-NAND

Nate Amsden
Bronze badge

have had this for about a month now

a 512GB 850 Pro, only complaint is it lacks power fail protection like the enterprise drives do (I was very close to buying the Intel 730 for this reason - it wasn't until after I ordered it that I realized it lacked this feature hopefully I will not need it - it is in my laptop, not concerned about losing power as much as I am system crashing or hanging which for me is pretty rare).

It seems pretty fast, given this is a 4 year old i7 laptop with SATA 2 no real point in benchmarking it, but it got rid of the lag experienced in firefox when downloading lots of things at once, running VMs is quicker too. I wouldn't say it's revolutionary compared to the Seagate Momentus XT hybrid I was using before but that may be because my workload generally isn't I/O intensive at all.

Also "upgraded" from Ubuntu 10.04 to Mint 17 at the same time(and on the windows side of dual boot XP->7), managed to keep 99% of my GNOME 2 user interface which makes me happy.

With the 10 year warranty I can imagine I'll probably be transplanting this drive into my next machine whenever that comes round.

Re: Not as big a problem as it looks

I don't agree with that myself. Even as a 18-year linux veteran I still have not even tried to root my Note 3, yet alone even consider replacing the operating system (I'd wager the s-pen wouldn't work well etc). If you choose your phone carefully based on Cyanogenmod support then maybe yes but obviously not many do that.

For me it's not too critical I just don't use any app that needs too much permissions. I do hope that future android versions fix this as it seems to be becoming an ever bigger problem.

Samsung keeps pestering me to accept a new license agreement on my phone and I keep declining.

Only been using Android since December so still somewhat of a newbie (was WebOS before that)

Re: Huh?

yeah.. no I don't think so. Bluray is not the future, tape was around before blu ray and it will be around after blu ray is a memory.

blu ray made it into facebook because there were folks there (probably still are) that hated tape(maybe their QIC 80 drives back in the 90s gave them some trouble so they figured tape was dead)

There was over 6,400 Petabytes of tape capacity shipped in Q1 of 2014 - 24% year over year growth and an all time record.

Ex Red Hat CTO installs self as Google Cloud boss

slow news day

I like Red Hat but I really don't care about exec changes, how is this anyone's business other than the person involved and perhaps the people they work with? Can't imagine anyone else caring (nothing specific to this CTO it applies to exec changes in general, or changes in general, no point in news stories about "oh this person is now over at this company!"

I can certainly understand caring if you know the person but otherwise, don't care. Even big wigs like Microsoft getting a new CEO - again I can understand if your going to be impacted by that change if you work at MS, other than that don't care who is CEO.

VMware updates vSphere, recommends new security fixes

Nate Amsden
Bronze badge

web client sucks

I remember having sort of high hopes when word first came out that a web client was coming, but it's just been crap. As a linux user for 18 years I'd rather use windows and the .NET client (normally interface with vCenter through Citrix XenApp + .NET client on windows because the vmware client on Linux Xenapp client doesn't work very well).

I know that the latest VM hardware version 12 requires the web client so for the 4 VMs (windows 2012) that need this hardware version I'm forced to use the web client when making configuration changes. It's painful. It sucks (I've only tried it on windows). I have a pair of ESXi 5.5 hosts (about to add a few more) the rest of the servers are ESX 4.1U3 (good 'ol thick ESX I like that much more than ESXi).

Fortunately even today I hardly ever have to touch the web client. Maybe by the time I have to regularly interact with it they will have it fixed, yeah probably not.

I read somewhere recently that vmware was (or perhaps has) turned the web client into an .exe instead of a browser plugin based interface.

I do this all the time.

White box switches out-sell Brocade, Arista in the data centre

Nate Amsden
Bronze badge

only 50%?

Last I heard Cisco's market share was up in the 70-75% range, with HP about 10-15% and most of the rest of the vendors sub 5% each. I seem to recall Juniper being in the 6% range (at one point in the past year or so anyway), Extreme was in the ~3% range until they bought Entarasys and doubled their market share to 6% (they were something like within 0.2% of Juniper's market share at the time they said). Brocade was in the 3-4% range as well, not sure on Arista.

If Cisco is down to 50% that is quite a hit.

Not so ESXi? Open sourcery could help VMware win... virtually

Nate Amsden

Re: VMware is probably screwed

I had a conversation with my former boss who has been using OpenStack for almost a year now (he is building a platform based on it for his new company's technology stack for customers). I quote him "Openstack sucks, but I know it". Something along those lines anyway. Openstack is not ready for prime time unless you have significant internal resources to keep it going or have a support partner like HP to help. A quote from HP "The easiest thing about Openstack is installing it, most organizations spend the bulk of their time simply keeping it running". You're in an endless upgrade cycle because the support cycles are so short both with community and with the enterprise editions from the likes of HP and Red Hat.

The storage on Openstack is even worse from what I'm told, a lot of organizations are finding that out the hard way and deploying enterprise storage behind it. The networking in Openstack sucks too, again quoting HP "after about 50 nodes neutron falls apart".

You can certainly make it work, I am told ebay has something like 200 engineers working on openstack there, most organizations don't have the time/money/resources to devote anything remotely resembling that to running stuff.

Openstack has a bright future, but it will be years(still!) until it's ready to be a product that you can install, support and be stable for 3-5 years without constant hacking/fixing/patching/upgrading.

A sign that it is getting stable will be when the likes of Red Hat and HP begin offering 3-5 year support agreements on Openstack, right now both are at 18 months. In HP's case the last 6 of those 18 months are dedicated to assisting migrating to the next version of Openstack which they emphasize is not trivial.

ESXi is not cheap to be sure (though the price you quote above seems pretty cheap perhaps that is not enterprise plus or maybe you have good bulk discount licenses). For me I compensate as much as I can by getting the most powerful processors I can to better utilize the license(which for us w/enterprise plus and 3 years production support comes to about $5k/socket without any fancy vmware addons none of which I need).

The value is still there for me, the stability and performance of vSphere and compatibility across operating systems (not likely many Linux shops are going to deploy Hyper-V). I had my first vSphere crash(PSOD) in 8 years of using it back in June (support believes it was a rare condition that was fixed by a firmware update released in May).

I don't understand the article's author though they seem to think that open source is the answer to everything when it is not. (I say that as a Linux user for 18 years now in personal and professional use, and have been a Linux user on the desktop for 16 of those years including right now).

If you want an open source hypervisor there are at least two of them out there. What was that? They suck? (Why else are you asking for VMware to opensource vsphere?) Well you get what you (don't) pay for.

Meanwhile my vSphere 4.1 clusters keep humming along running our ~550 or so Linux VMs.

Community chest: Storage firms need to pay open-source debts

Nate Amsden
Bronze badge

Re: Half of the Story

You have the option to participate in open source true. The reality for probably 98% of orgs out there is even with that prospect they do not participate because they don't have the skills/etc to do so.

I've seen countless companies including every one I've worked for use open source stuff for various things and pretty much never contribute back. If they found problems with some open source package the solution was typically not to use that package and try something else, rather than spend time beyond basic community mailing lists to get help resolving it.

Many folks see open source not as freedom but as "don't have to buy something". Which in some cases creates many more problems than going out and actually buying something that may work better.

(Linux user for 18 years, 16 of those spent supporting it and other open source tech along side commercial tech, so not a MS fanboy by any stretch!)

If your a Linux user and want to support open source, use a commercial distribution like Red Hat. You get quality software, and you know you are supporting a lot of open source projects at the same time. It's a much easier sell to management then saying they should donate $$ or hire some developers to contribute code back.

Hey FCC, Comcast-TWC merger is bad news for Netflix, says Netflix

Nate Amsden
Bronze badge

how does the merger impact broadband consumer choice

Since cable orgs are generally granted monopolies over their areas, there should be little to no overlap between the two, so consumers don't have a choice between comcast and time warner in a given market.

I'm against the merger myself as well since I think they would be too big, and I like the concept of separating content creation (NBC Universal etc) from distribution. But anyway I don't see the reasoning behind broadband competition.

I do find it somewhat amusing some folks though they whine and complain about lack of competition when often enough there is multiple broadband providers in their area whether it is DSL, mobile internet, sattelite or something like that. Then they say "oh yeah well all those suck, they are too slow". Which basically means cable companies are doing a good job at providing competitive service.

Some folks (I was one at one point) want the cable isps to be regulated like common carriers. But again look at the state of the DSL market -- you're likely to see the cable internet market go the way of that if they are regulated in a similar manor.

For me - I use cable internet from I guess what you could call a "municipal" provider - they serve the city I'm in of ~41k people only (and I'm spitting distance practically from Youtube's HQ, I walk by it on the way to work). Other ISPs in my area include AT&T Uverse, and a couple others. The broadband offered by this small cable provider is somewhat on par with what I got with Comcast before I moved here, though there is no business class offering(that I know of anyway) that can give me faster upload speeds (I have a server at a local colo and it would be nice to have faster upload to it - as-is I get about 2Mbit - if I paid more the most I could get is about 5Mbit upload).

I won't do Uverse at least in part because last I checked(just now actually) it was not compatible with my Tivo S3 or S4, and I have no interest in using their DVRs in place of Tivo, even if Uverse was free. That doesn't stop them from sending me stuff in the mail to sign up at least once a week seems like.

VMware EMC partner Cisco inks reselling deal... with Simplivity

isn't

scale computing bigger than Simplivity at least? I've never used any of them myself but

http://www.theregister.co.uk/2014/08/14/scale_computing_scales_sales_up/

"It has amassed more than 900 customers who use more than 3,500 HC3 appliances, "surpassing the number of customers of its closest competitor by a wide margin.""

From your own article and yet you seem to forget so quickly.

Hell I don't know why I remembered, I don't even really care.

Forrester says it's time to give up on physical storage arrays

Nate Amsden

cheap is relative

What is cheap x86 servers? My fairly loaded HP DL380Gen8s (24 core/48 thread 192GB 4x10G 2x8G FC w/4 hour onsite support) and vSphere enterprise plus are around $30k each. The cost hasn't changed too much since we bought our DL385 G7s 3 years ago (other than the systems are about 2x faster than our 3 year old boxes in the same power envelope)

Maybe to some that is cheap, maybe to others it is not. To me it's reasonable with the ability to get good consolidation ratios out of them, and they have been *extremely* reliable.

Though HP 3PAR has done pretty amazingly well at being a low cost leader in all flash systems recently(relative to their main competition anyway)

HP lets the SAN shine: StoreVirtual now bigger, flashier, OpenStack-ier

I think

the 7200 designation for that array is incorrect in the article, at least it's not the number I heard it was going to be called. The 7200 is an entry level system that was released in December 2012. I would not expect HP to re-use that number for a brand new system that would not be smart. But I will confirm with 3PAR. Not that you can't equip a 7200 with all SSDs if you wanted.

Linux Foundation says many Linux admins and engineers are certifiable

Nate Amsden

Re: Way too simple.

honestly I probably couldn't (quickly) do multiple of those things without referring to previous examples I have used in the past. I feel I am adept at Linux having used it for almost 18 years now and well I just know I'm very good. I also know where to draw the line, I'm not going to go out on a half baked expedition to try to get some obscure open source project to work when I can get a commercial solution that does the job just fine (I used to do this back in the 90s, then I learned that was a bad approach oh how I remember the struggles of configuring linux to be a PPP dialup server what a pain that was).

But (like many I suppose) I don't have every little bit memorized (esp detailed configurations) if I'm not doing that every day (last time I really configured postfix was probably 3 years ago, it's just run since then). But I have all my docs, all my config examples. I also actively avoid doing things like rewrite rules in apache as well because they are PITA (prefer to do it at my real load balancers it's far easier).

And don't get me started on squid, that thing is a PITA. Always has been, I've set it up maybe 3 times in the past 14 years. Even with docs and examples it's a major PITA.

So I honestly, very honestly would probably not do so hot on this test, but I absolutely know that I am very good with Linux (having been tech lead on every project I've been involved with more or less since 2003) and have employers falling head over heels constantly trying to hire me (sorry, not interested I am happy where I am at now).

I've never put any faith in certs, generally they are not worth a whole lot. When I look at candidates I generally rank them lower the more certs they have, especially if they have really stupid ones like A+ type stuff. To-date my intuition on that has been accurate, generally candidates that have a lot of certs don't tend to know a whole lot. Same goes for candidates that have long resumes, the longer the resume the less they seem to know.

I never recall anyone ever asking me for a cert. I think it is more common if I was a dedicated network engineer. I do networking whether it's L2-L3 switching, or L4-L7 load balancing, (no dynamic routing), no certs though.

I suppose the biggest reason I don't recall every nitty bitty configuration detail, is really I have more valuable things to store in my brain.

Microsoft, Google link arms on browser vid chat

MS has been doing a great job

of breaking their own skype clients recently. Whether it is the older linux clients, killing off support for windows phone 7, or whatever..seems like a bad idea. Earlier today I noticed someone try to invite someone into a group chat (text chat, not voice/video) and skype said in the chat "(username) needs to update Skype to participate in this chat. Help by sending them to Skype.com/downloads. Learn more about new group chat."

stupid.

VMware buys CloudVolumes to speed app installations

Nate Amsden
Bronze badge

so

how is this different from something like XenApp ? I am certainly not an expert in either but have used XenApp a bit over the past few years(handy for thick management apps like vCenter over a WAN connection), and it makes apps look and feel like they are local, and drive letters are mapped automatically so you can get data from local drives and put it up to the hosted app, and I think it does printers and stuff too.

aws is a f*cking chore to use

it's so limited in it's features/capabilities it's maddening. Those who don't understand that haven't done any infrastructure work in the past 15 years because that's how far back in time you gotta go (if not further).

Object storage bods Exablox: RAID is dead, baby. RAID is dead

Nate Amsden
Bronze badge

seems kind of limited

They only support SMB (CIFS) ? Really? I think most would argue that NFS is a far more commonly deployed protocol amongst servers anyway.

I suspect these guys are not using RAID as in mirroring whole drives, they are probably mirroring (or more likely triple mirroring) objects across systems. So if a drive fails the objects are mirrored elsewhere, you don't need to wait on that drive or a hot spare or something to kick in. They may be using RAID for the operating system disk(s) on their controllers (or perhaps just a small SSD).

3PAR has a nice RAID system too which is similar, breaking the drives up into 1GB (as of a few years ago before that 256MB) so rebuilds are very fast and the design is quite scalable. You can even yank a drive out of an array and the system will go into "logging" mode writing data that would go to that drive to other locations for up to something like 7 minutes at which point the system assumes the drive is dead and rebuilds. You can gracefully evacuate drives as well for seamless maintenance.

IBM's XIV does something similar too I believe but last I checked they still limited themselves to 7.2k RPM disks and RAID 1 only (I suspect their CPUs can't keep up with the calculations for RAID 5/6 at that level, with 3PAR that is handled by their ASIC).

XIO (assuming that's what they are called now) does RAID across drive platters, which I thought was quite creative too, they can fail individual platters in drives and not have to replace the disk (system ships with enough spare capacity that you don't take a capacity hit over the 5-8 years or so of the system warranty).

It's not uncommon for a 3PAR array to have more than 50,000 RAID arrays on it with just a few hundred spindles(much more for those on systems older than current generation since the size of the chunklets is smaller).

Nexenta reckons it has Edge in squeezing your object storage BLOB

Nate Amsden
Bronze badge

also competing

I'm sure there is more but DDN comes to mind(absolutely massive object scale with 1 trillion objects/cluster), as does Red Hat storage server(which is software only). I think NetApp has object storage too though last I saw it was quite limited in scale (relative to say DDN anyway).

I think the potential market for this stuff is pretty small, much of the object storage systems I suspect will be in the service providers and well there's only so many of those.

Most small orgs don't need object storage, NAS is more than sufficient (say up to and including a few PB).

Re: i can't patch

LDS - I don't know. I don't tend to skip patches I just let the system patch whatever it wants. I looked and indeed I do not have KB2929437, I'll take a snapshot of my VM and see if I can get that one to install(faster to recover with vmware than with windows system restore for me)
