RE: nas storage

Mike: You can also upgrade to the newer quad ethernet card, a single port is about a 1.5x speed increase, and a four port VIF will bump you about 1.7x performance. That should help a lot of your bottleneck issues. Sean has some data I sent him..that you can grab. Sorry..but when I bought the 760's you have there, thats the only card they offered. -----Original Message----- From: Michael S.

I am required to stick with it for a while yet. Solaris 2.6 run against F760s with ONTAP 5.3.4 performs more slowly local storage would. If you can refute this, then tell me how to fix my installation. I _must_ run NFSv2 to get decent performance, and ONTAP limits NFSv2 packets to 8K. So I must suffer with small transfers. I don't yet have enough storage on these filers to build another test system with Solaris 7 that can handle the load. I'm stuck in the middle without resources to test adequately that Solaris 7 would handle the load better. You make a blanket statement without supporting facts.

The routing table is built primarily in 3 ways. Static routes (like the default route and interface routes), ICMP redirects, and if used routing protocols like RIP. The filer will look at the routing table to decide the first hop for the reply. To views your route table, try netstat -rn.

RE: Solaris 7 & NFS2/NFS3/TCP/UDP....
by Rainchik, Aleksandr (MED, Non GE) 22 Mar '00

http://www-viz.tamu.edu/~sgi-faq/faq/html/admin/69.html "[NFS3].... is not supported by the automounter." You can mount it as NFS3 manually, or from /etc/fstab, or using AutoFS, but not via automount (which we use). I've tried to use -vers=3 in automount map, no luck :( I was very surprised... -----Original Message----- From: Keith Brown [mailto:keith@netapp.com] Sent: Wednesday, March 22, 2000 5:35 PM To: Rainchik, Aleksandr (MED, Non GE) Cc: toasters(a)mathworks.com Subject: Re: Solaris 7 & NFS2/NFS3/TCP/UDP.... The usual drill for NFS mounting when no options are specified, as defined by Sun/Solaris (if you accept Sun/Solaris as a definer here?), is to mount using the highest revision of the NFS protocol available on both the client and the server, and the first connection oriented protocol available (usually TCP), falling back to the first connectionless protocol (usually UDP). So if the IRIX folk were paying any attention to the Solaris folk when they put their implementation together, as long as you have: filer> options nfs.v3.enable on filer> options nfs.tcp.enable off set on the filer, you would be in with a fighting chance of getting your 32K/NFSv3/UDP aspirations satisfied, even without specifying any mount options (32K xfer sizes are the default for NFSv3).

Solaris 7 & NFS2/NFS3/TCP/UDP....
by Rainchik, Aleksandr (MED, Non GE) 22 Mar '00

22 Mar '00

Hi, We have brand new E450 running Solaris 7 and NetApp Release 5.3.4R3 and we are planning to use NetApp as a ClearCase VOB storage. Both are on 100mb/full switched fast Ethernet. I was trying to play with Postmark to identify what is best for performance, like NFS2 or NFS3? TCP or UDP? What values for rsize or wsize? r/wsize TPS read write -------------------------------------- NFS3 UDP 8K 38 223.42 720.64 NFS2 UDP 8K 3 13.81 44.53 NFS3 TCP 32K 2 12.67 40.86 NFS2 TCP 8K 2 13.14 42.39 a) For some reason, the best results I've got was with -o vers=3,proto=udp. NFS2, or NFS over TCP looks like a joke... It's like 20 times slower. b) There is no way to use w/rsize=32768 with NetApp with NFS3 over UDP. Why? I can do it when mounting from Solaris. Any comments? Thank you.

RE: NAS Storage
by Kirschner, Lewis 22 Mar '00

My apologies to everyone on this forum. The statement below was an overreaction to a legitimate issue that was raised with regard to performance on our filers. My general comment is that if the performance of the filer seems inadequate for your application, we'd be interested in getting the specifics so we can either address the issue, or explain how to tune things so you can get the performance you need. There's a tremendous amount of variation depending on the workload, network configuration, etc. etc., which makes it difficult to make blanket statements about the relative performance. In general, we have the expectation that the filer should perform similarly to local disk. Sometimes faster, and there may be situations where it's slower.

The minicore file is not currently controlled separately from the Autosupport. I have opened a RFE (23389) for consideration of a new feature to provide the ability to control the sending of the minicore email separately from the Autosupport email. A separate option to turn on/off minicore email and a separate list of recipients.
