Re: [Veritas-bu] Sun GigaSwift (ce) cards
On the Sol10 network inquiry. They have rearchitected the stack so that UDP and TCP are not separate STREAMS between IP. They have combined them to improve on efficiency by about 20% on network transactions. Lots of info here: http://www.sun.com/bigadmin/content/networkperf/ Has anyone used jumbo frames? We are thinking about doing this on our backup network but I believe that ALL the clients that use that network would have to be configured for jumbo frames. Does anyone know this for sure? Everyone on the LAN should be configured for jumbo frames. One way around this would be to create a separate subnet/vlan that uses jumbos. I'm not sure that routers can handle different MTUs on different VLANs on the same interface. I couldn't figure out how to do it on my Juniper M10 but have not really investigated fully. You should get improved performance with jumbos. Whether you'll notice any actual application-level improvement or not of course depends on where the bottleneck in your network is. ___ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
Re: [Veritas-bu] Sun GigaSwift (ce) cards
We use them and there is some tuning. I'm not near a system with them, but I do know we used the Sun documentation on these cards and set the TCP high watermarks to 65535. Some changes that used to go in /etc/system for 100Mb cards now go in a separate file for the ce cards. These in /etc/system: set sq_max_size=100 set tcp:tcp_conn_hash_size=8192 By the definition of GbE, auto-negotiation must be left enabled. Found this, but we've not followed it all yet: http://www.csie.ntu.edu.tw/~hungsh/2001%20SUPerG.pdf What we have not done is a proper experiment.

RE: [Veritas-bu] Sun GigaSwift (ce) cards
Thanks. I set the hiwat, then came across this: http://seer.support.veritas.com/docs/273288.htm Doesn't seem to affect me, so. Will look at the others. Clicking on the link http://www.csie.ntu.edu.tw/~hungsh/2001%20SUPerG.pdf didn't work, but going to http://www.csie.ntu.edu.tw/~hungsh/ and following from there, didwierd.

I am using a couple in Solaris 9 master/media servers.

RE: [Veritas-bu] Sun GigaSwift (ce) cards
I am using these cards with little tuning, but I am also using these to create a trunk (cisco etherchannel) with them for our backup network. The backup servers have a 4 x 1gig trunk to the backup network. This works very well . . . I also just found out that the trunk software is free to use on solaris 10 (we normally pay about $1500 for anything other than sol10). I was also told that sol10 has big performance gains for the networking, but I am not sure specifically what those gains are, I will try to find out from one of our sun guys. Has anyone used jumbo frames? We are thinking about doing this on our backup network but I believe that ALL the clients that use that network would have to be configured for jumbo frames. Does anyone know this for sure?
