RE: Experience with Acopia

Thanks everyone for replying.. From what I heard and have seen the product at customer locations is its reliable and fast...

I think some of the pros that you ignore or don't mention are: 1. virtualizes your NFS/CIFS storage so you can move/manage/upgrade that backend without user downtime or them even noticing. I like to think of it as VxVM for NFS/CIFS. In my case, we're looking at it strictly from an NFS point of view. 2. Allows you to do HSM style management. Files which aren't accessed in a certain amount of time can be migrated transparently between backend storage pools. 3. It's not trying to pass through the NFS traffic, it's both a server and client and does it's own translation. This is unlike the Rainfinity box which sat in the middle of the stream and played games with what the clients saw. 4. It's an appliance. I don't have to setup an OS and then applications and get it all configured to make it run. It's pretty much plug and play. Just like NetApps. Jonathan> 1..

If absolute raw performance is so darn important, why are you using NFS in the first place? Have you looked at how much overhead VxVM puts into a system versus just accessing the disk directly? I never see any complaints there, and I suspect (no real numbers) that VxVM puts some measureable overhead into the loop. But the benefits outweigh the costs by a large margin. Also, if I were setting up an Acopia, I would have my clients connecting via the public LAN, and the Acopia and the backend storage all talking over their own dedicated LAN.

Another namespace question.
by Alex Bochannek 20 May '05

20 May '05

Since there has been a lot of discussion about namespace virtualization lately, I thought I'd throw in a question. Nightly, an application creates a fairly large number of files, makes a new directory on an R200, and then dumps the data to it. For a number of reasons, the volume this data is on is 5TB in size and it's currently half full (or half empty, depending on your way of looking at things). The R200 is running 6.5.3P4 and has plenty of space for additional volumes. >From the perspective of the application generating the data as well as from the perspective of the users accessing it, the volume is expected to be accessible under one particular name. The obvious question is: What do I do when /vol/foo runs out of space and I need /vol/foo2? Usually, I'd play automounter tricks since the directories under the volumes are all uniquely named, but I'd rather not. This is NFS-only and the clients are all sorts of different UNIXish systems. Any suggestions? Thanks! Alex.

RE: Experience with Acopia
by Kennedy, Jeffrey 19 May '05

I don't know about the pro's but the con's you cite are not accurate in most cases. 1) pretty much the case 2) how do you figure? They use CIFS and NFS just like every other network client. They just happen to be the only client to your servers and the only server to you clients if you go all the way with them. But you don't have to go all the way if you choose not to. You can have just certain file systems under Acopia control. 3) They have owned up to a .5% latency insertion which, given their architecture, I can believe. We'll be looking to verify that claim in our testing. 4) Not hardly, at least not in the NFS world. Since this becomes the mount point for all your clients there's no way someone who needed something like this would be able to tell all the clients "stop doing stuff while I remount all the hosts". This is a put-in-place-and-leave-it-forever appliance. 5) Again, how do you figure? This appliance allows you to mount multiple NFS or CIFS shares from existing servers, aggregate them together into a single view, all the while increasing performance by turning the backend into a storage grid. Are you sure you're talking about Acopia? 6) No idea about that one, but I would use NetApp as the backend of this appliance for certain. The basic idea, given a compute farm and NAS shop (NetApp specifically in this case), is to have the Acopia import however many qtrees you see fit to make up a single file system for the world. Then have it present all of those qtrees as a single file system and mount point. Depending on your policies you can have file writes round robin or do latency based file placement. This is the basic concept of a storage grid, spreading storage IO across multiple systems while still presenting a coherent file system and view. Other people accomplish the same idea in different ways (Ibix, Panasas, Isilon, Lustre, etc..). Acopia is unique in that it puts that capability in the network (switch) rather than in a server appliance or software. I'm not saying that's better, just unique. There are other functions the Acopia can do besides the storage grid but everyone has their own requirements and goals. As to VFM for global namespace, fine if you are a CIFS only shop. They're NFS support is sorely lacking and basically a hack of automounter. They have other functions also, like data replication and site failover, but if you're a mixed environment don't bet on them just yet. ~JK ________________________________ From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Jonathan Cragle Sent: Wednesday, May 18, 2005 9:22 PM To: Venkat Appineni; toasters(a)mathworks.com Subject: Re: Experience with Acopia Pros: 1.

You can either have just 1 card that you will need to remove from the machine with the hardware problem and place into another server or in our case we just got 2 cards and we can configure 2 separate machines to boot off the same lun. You just need to make sure that they are not trying to do it at the same time. Only one machine should be up on one lun at a time.

We are testing the Qlogic 4004 card and it works well. It's pretty easy to setup. You have it point to a lun and then boot off a CD and install Windows on that new iSCSI drive. I personally think it's a great way to get much higer availability without the added complexities of a full cluster. We have spare servers standby. With iSCSI booting, if we run into hardware problem, the operator can shutdown the server, boot another one in place and be up and running in less than 5 minutes.

best backup for netapps
by Constantin Bogomolnyi 17 May '05

17 May '05

Hello, I'm wondering what is the best backup system for saving big netapps we have tried alot of solutions , but we finished by running 3 sets of netapp in snapmirror so A(master) replicates to B and C (slaves) all have now raid_dp enabled and spare around . So we have realtime B and C backups (we may cluster A and B) . But as its quite expensive "backup" i'm looking for some classic backup with tapes for example but i know from the past that tapes can be big pain to manage (specialy as we have around 2.5T of data on A) Anybody have some "tape backup" that realy works ? sub question : anybody have tried to attach a cheap ide raid shelf to scsi port of the netapp and use it as backup ? today its cheap to have 14x300 gig ide disk array with scsi port , so it could be better than tapes if its directly attached to the netapp , nan ?

RE: best backup for netapps

Probably the best question is what exactly do you want these backups for? To be able to restore files people mistakenly delete/corrupt? For full-on disaster recovery? For long-term archiving? I think for the first one, various online or near-offline solutions like you've mentioned (ndmp to another server, etc) are probably fine, but then you could probably do just as well by just relying on snapshots and keep it simple. My personal opinion, which others might disagree with, is that for disaster recovery and *especially* for long-term archiving, you really need good offline storage like tapes. Something you can have shipped to a storage facility buried in a mountain somewhere. With enough money you could have multiple netapps around the country/world with snapmirror or somesuch replicating between them, which is great for DR too, but in the end I'm just not comfortable without something offline to fall back on. Imo the best solution is good backup software and a large automated tape library, but it's not going to be cheap. Even just the tapes can be a huge expense. We're still doing backups over NFS here, largely because when we tried doing NDMP a few years ago it just did not seem ready for prime time, we had too many problems. I'm very much interested in trying NDMP again though, as backing up over NFS is not the most efficient solution. I admit though, I've been in this business a long time and I'm a bit old-fashioned. Other people might be more comfortable than I am with relying entirely on hard drives for disaster recovery. -- Michael W.

13 May '05

Dear Sir, I am Yuri Krakov, I represent a top company executive in Russia. I have a very sensitive and private brief from this top executive to ask for your partnership to re-profile funds over 15,000,000.00 euros. I will give the details, but in summary, the funds are coming via a bank in Western Europe, and this is a legitimate transaction. You will be paid 10% for your "management fees", if I am able to reach terms with you. If you are interested, please write back by email prestroika(a)mail15.com and provide me with your confidential telephone number, and email address and I will provide further details. Please keep this close to your chest as much as possible; we cannot afford any political problems. Write me back. I look forward to it. Regards, Yuri Krakov.

We been running a FAS960 for about a year. Upgraded to on OnTap 6.5 last fall IIRC. All our volumes are DP (Dual Parity). Don't worry 'bout stability. Using DP results in an increase in fault tolerance.

RE: Snapmirror and locked files
by Umerov, Mark 12 May '05

As I understand it, when the block level transfer of the blocks that changed between last transfer and the time the new snapshot was taken on source is completed, Netapp makes this just transferred snapshot on the target the active file system and removes previous snapshot from the source - the target at that point is synchronized with the source at the time of the last snapshot. When the snapshot on target volume becomes the active file system, what happens to files that reside on data blocks that changed in case these files happen to be locked by clients? Does the question make sense? If it does not make any sense, let me try to ask it differently... Unlike typical NFS, when CIFS clients read the file, the file is actually locked until read operation completes. In other words, other processes cannot update the file while the file is being read. What happens in case of Netapp if CIFS clients read the file from the snapmirrored volume and the snapmirror transfer completes *while* the file is being read? thanks again, Mark -----Original Message----- From: Eric Kimminau [mailto:ekimminau@rainfinity.com] Sent: Wednesday, May 11, 2005 12:40 PM To: Umerov, Mark Cc: toasters(a)mathworks.com Subject: RE: Snapmirror and locked files Hi! I know that snapmirror is a block level solution, which, to my knowledge, has no real knowledge of the files using those blocks. Therefore I don't believe that it has no knowledge of file related locks. Then again I could be completely wrong. I would be very interested in hearing if you hear anything other that what I have below. From the iSCSI best practices paper: http://www.netapp.com/tech_library/3250.html 3.9. File Systems That Are Not Capable of Snapshots Applications that are implemented on top of file systems that are not capable of Snapshots, such as NTFS, represent the simplest scenario from a backup and recovery perspective. When backing up these applications, applications must be first quiesced, or taken offline, in order to avoid open files or files changing during the backup operation. Then, file system caches must be first committed before the backup operation commences. The application remains quiesced, or offline, until the backup is completed, at which point normal application operation can resume. This can result in a significant period of unavailability for the application. Some applications have a built-in hot backup mode, allowing a backup to occur while the application operates at a reduced efficiency and often, limited capabilities. This type of mode is typical in messaging and database applications such as Microsoft Exchange and OracleR. It will result in higher overall application availability than not using hot backup mode. However, it can potentially still result in a long interval of reduced efficiency and limited performance. One final alternative is to use an open file manager from a backup software vendor. These applications are designed to handle backup operations on files that are still locked by an application. They work well for simple applications, such as home directories and shared documents. However, they should be avoided with complex applications, such as messaging applications or databases. ================================================================= This of course assumes that snapmirror does not use the SecureShare methodology described in this paper which handles multi-protocol opportunistic locks but I don't know if snapmirror interacts in any way: http://66.102.7.104/search?q=cache:QtaPZkw0OCwJ:www.nluug.nl/events/vj99 /papers/pawlowski.ps+snapmirror+locked+files&hl=en&client=firefox-a Data integrity A thorny problem in the multiprotocol file access space is managing shared access to data in the face ofrestrictions imposed by client locking. The technology in Network Appliance filers that accomplishes this is called SecureShare, and is described in [Borr98]. SecureShare enables UNIX and Windows based applications to concurrently access and update sharedfiles, with the integrity and cache coherency of the shared data being protected by system-enforced locking and file-open semantics. The locking semantics between Windows NT and UNIX differsignificantly. Heuristics control simultaneous access to a file by both UNIX and Windows NT. Simultaneous access in a multiprotocol environment might compromise the data integrity of a file(when locked against unwanted modification by other clients) if not properly managed. UNIX clients have rather lax standards of locking compared to the more restrictive lock semantics of Windows NT. SecureShare also implements a multiprotocol extrapolation of the Windows networking performanceoptimization known as "opportunistic locks" (oplocks). Oplocks allow a Windows NT client to aggressively cache data and lock state in the absence of sharing. A Windows NT server will extend anoplock to a Windows NT client when no other client is sharing a file. When another client attempts access to a file on which an oplock is held, a Winndows NT server will "break the oplock" forcing allmodified data and lock state back to the server, and the server will then negotiate file access between clients engaged in data sharing. The SecureShare implementation of oplocks provides Windows-basedapplications the performance benefits of aggressive client-side caching and the assurance that the same "oplock break" protocol occurs in the event a UNIX-based application attempts to access an oplockedfile. ---------1---------2---------3---------4---------5---------6---------7 Eric Kimminau Email: ekimminau(a)rainfinity.com Senior Sales Engineer Office:248.766.9921 Rainfinity Fax: 248.393.8037 www.rainfinity.com ________________________________ From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Umerov, Mark Sent: Wednesday, May 11, 2005 2:58 PM To: toasters(a)mathworks.com Subject: Snapmirror and locked files greetings, Does Netapp allow locking of files on snapmirrored (read-only) volumes?
