CIFS spec.org benchmark
by Todd C. Merrill 17 Feb '09

17 Feb '09

http://www.spec.org/sfs2008/results/sfs2008.html Oooo..."SPECsfs2008_cifs". How about some CIFS benchmarks, NetApp? (Yeah, yeah, save the griping about how benchmarks stink and all that. I know.)

7.3 and MacOSX
by Todd C. Merrill 17 Feb '09

17 Feb '09

After a recent upgrade to 7.3, we have noticed all/many of our MacOSX clients banging the crap out of the filer that hosts their home directories (over NFS). (The ops are 75% NFS v3 lookups and 25% access calls.) Anybody else seen anything similar? It's definitely SpotLight that is the cause, but other than the filer OS change, the Mac clients have not changed one bit. It's almost as if the Macs think they have an entirely new volume/filesystem to catalog. Until next time...

7.2 -> 7.3 performance improvements: did you measure?
by Todd C. Merrill 17 Feb '09

17 Feb '09

Folks, We beat our 6000's pretty hard. We were hoping the upgrade to 7.3 would really help the throughput of these group of filers due to the threading improvements, but our results were less than spectacular. If anyone has characterized their usage before and after an upgrade to 7.3, I'd like to hear about it and share some thoughts/charts/graphs/etc. Until next time...

slow NIS push with filer as NIS slave
by David N. Blank-Edelman 13 Feb '09

13 Feb '09

Hi- I was thinking of contacting support, but before I do I was curious if anyone else has encountered the following situation: We're still (sigh, but this is changing as we migrate off of it) using NIS. We thought it made sense to use the built-in functionality to make the filer (a 3020) act as one of our NIS slaves for redundancy and performance reasons (so it wouldn't have to query off box). That seems to work fine, but for some reason the yppush of the data from our master takes a much, much longer time to return from the filer than any other of our nis slaves. Has anyone else encountered this issue and dealt with it? I realize that we could go the vaudeville route ("Patient: Doctor, my arm hurts when I move it this way. Doctor: so don't move it that way." but I was wondering if there are other solutions (options, etc) that we should try first? Thanks! -- dNb

Weird perms issue
by David McWilliams 13 Feb '09

13 Feb '09

One of our Windows admins tried to 'fix' what he thought was a perms problem on one of our mixed qtrees. I've spent most of the day working on it and it looks to be solved, apart from an error we get while using a particular CAD application - Ideas from Siemens running on Solaris 10. We can save files, etc. I did a truss -f on the script that starts the process and i get the following output.

Re: NFS and VMFS on a single ESX host
by John Sellens 13 Feb '09

13 Feb '09

| Looking to run NFS and VMFS ESX data stores on a single ESX host. | | Anybody else doing it? | | Gotchas? We do it (total of 15 or so ESX hosts, 4 filers), though most of our ESX datastores are VMFS on LUNs from the filers. Works just as expected. I haven't looked closely at relative performance, but we have a number of low use VMs where disk performance is almost irrelevant, and tend to put them on NFS datastores. I like using NFS datastores: - snapshots let us mount old .vmdk files for "easy" file restores - doing it with a lun seems more of a pain - easy to adjust the size of a datastore on the filer - easier to create a machine - we lean towards LUN per VM, which means creating a new VM is more annoying One inconvenience of NFS datastores is that they need to be added separately on each ESX host. I don't know if adding a datastore can be done from the service console shell, but we use the VI client, which is tedious. With LUNs, we configure them once on the filer, and then our ESX rescan scripts result in the storage being visible everywhere. Hope that helps - cheers! John

RE: SSD. What's about?
by Kennedy, Jeffrey 13 Feb '09

13 Feb '09

Right, but the question was what's it all about. The SSD stuff is fairly robust, at least in the last couple of years. Burn-out is a concern but that's why you raid it; run mirror'd SSD Lun's. It's expensive for sure but if performance is everything you can get it in spades. For several years now you could get this kind of performance elsewhere; Sun comes to mind immediately. So if availability was less of a concern and you were a speed-freak, Sun owned Netapp by very large margins. And with other vendors pushing the availability envelop and creeping into Netapp's sweetspot, along with all the other features they've been using to entice buyers, Netapp had to do something. I think it's a great move. The capability is probably needed by only a small portion of the population but that portion has a lot of money to burn on performance.

Re: RE: Avamar VS SMVI
by hollandwl＠gmail.com 10 Feb '09

Snapvault is not EOL. The next version of SMVI will be including snapvault support. In the interim, Matt Robinson of NetApp has written SV SMVI (Snapvault for Snapmanager for Virtual Infrastructure). I've tried it in our development lab and it seems to work really well. Take a look at it at http://communities.netapp.com/docs/DOC-1868;jsessionid=A4775C7EF68BD0E628BE… The S550 is being discontinued and therefore snapvault primary for it is EOL. However, snapvault for the FAS series is not EOL.
