RE: Netapp vs eva800 with Microsoft Windows Storage Server 2003
by Carter K. George 17 Feb '06

17 Feb '06

well, for serving up windows CIFS file shares, the windows storage server platform is pretty strong. when combined with hp's polyserve-based cluster services, it has client transparent failover, access to the same shares from multiple nodes at the same time, and snapshot integration with the eva8000. now if the workload is NFS, that's another matter. since an hp windows storage server cluster scales linearly as you add nodes, the performance can be tremendous with an eva8000 on the backend. we have test results on CIFS showing linear scaling up to 1,600 Megabytes per second (not Megabits) on an 8 node Windows cluster, with all nodes mounting, reading, writing, and exporting the same file systems from all nodes concurrently, with automatic load balancing of client CIFS connections across the nodes. carter ________________________________ From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Langborg Tom Sent: Tuesday, February 14, 2006 11:36 PM To: toasters(a)mathworks.com Subject: Netapp vs eva800 with Microsoft Windows Storage Server 2003 Hi I need some arguments for netapp vs Microsoft Windows Storage Server 2003 with eva8000.

R100 ggregate size limited to 8 TByte?
by Peter W. Osel 17 Feb '06

17 Feb '06

Hello fellow toasters, I plan to migrate my R100 (84 136 Gbyte disks) (yes I should upgrade to newer systems ;-), to flexible volumes, ideally I would create a single aggregate (12+12+12+12+12+11+11 disks leaving 2 HotSpares). Someone mentioned that this would not be possible, and that the R100 has a limit of 8 Tbyte for the aggregate size, thus I had to create two aggregates? Is this true? could not find any hint on the NOW site yet ... Cheers --pwo

Maildir + netapp performance tuning?
by Adam McDougall 17 Feb '06

17 Feb '06

Does anyone have any tips for tuning a netapp (and/or clients) for nfs access to Maildir email folders? I know people do it, and potentially the load on the server(s) could be less than mbox because you arent shovelling around huge files, but it seems like the netapp is a little slow with opening a larger number of files for reading one by one. By large I mean over a few thousand (three to 130 thousand I have tested with) and slow I mean between 200 and 500 headers read per second from nfs. It is only slow if the filer does not have it cached already, because followup folder opens get several thousand headers per second throughput, similar to mbox. I have not tried other nfs servers, but I have attempted to simulate the load from courier-imapd or dovecot using a shell script to read 2 dozen lines from each of several thousand mail files, and the delay seems to be the netapp. Additionally, if if is a fresh folder open (not cached anywhere), the first 2,000 or so message headers load quickly, it slows down to between 200-500/sec for the next few thousand, and if you let it get above several tens of thousands, it continues to slow even more, down to less than 100 headers per second. I am somewhat dissapointed that the NOW forums and documentation is pretty much devoid of any mention of Maildir, let alone tuning for it. I have a FAS940, not heavily loaded, and the clients for this are a small cluster of Dell Poweredge 2650 dual 2ghz xeons, running in pre-production environments of either Debian Linux or FreeBSD 6.x. The filer is running 7.0.3, and the files are stored in a flexvol in an aggregate spanning 3 DS14's full of disks (28x36, 14x72).
