So I've gotten link aggregation working on the server and one of the clients (had a small adventure recovering an older Linksys SRW2008 switch). The performance actually dropped a bit on the one client. (the easiest way to test this is to just unplumb and replumb the various combinations of card

So this is a good call all around. I finally figured out (once again, thanks to another helpful post on this board) about how to benchmark with DD. Doing the direct reads and writes to a non-deduped, non-compressed filesystem over NFS, I get about 110 MB/sec reading, and writing, which is very c

Thanks for the tips. I'll check out Wireshark. A second question: how do you assess performance within the box itself? I'm using iostat -x, but there's also bonnie (which I've never used). If I want to figure out if the network is the limiting factor, I should also figure out the limiting hard-

I think the benefit of link aggregation in OSOL is when multiple clients connect to the single server. Because link agg in OSOL is based on L2, L3, or L4, even at L4 you would have to use different ports/protocols to see any improvement on a single client. Plus, I'm not sure a single workstation

Thanks, guys. I actually have two ethernet ports on the server, so in principle I should be able to use automatic link-aggregation in OSOL to do this, right? If I understand correctly, the two adapters get teamed, and only require a single IP address, right? Of course, then to see any improvem

I use lacp with two NICs on my server, and during seq writes, can nearly fill the pipes, 200mbps. This is with two clients. I have not seen packet loss, but I'm not looking either :). You can specify the load balancing policy with opensolaris, and I use L4. This way, two clients using the same

Thanks to the help from many people on this board, I finally got my OpenSolaris-based NAS box up and running. I have a Dell T410 with a Xeon E5504 2.0 GHz (Nehalem) quad-core processor, 8 GB of RAM. I have six 2TB Hitachi Deskstar (HD32000IDK/7K) SATA drives, set up as stripes across three mirr
