And sufficiently different that our Ray 2 can be made to function where our Ray 1 packet loss is 15% or more (as reported by utcapture). This list has suggested that our problems are possibly duplex mismatch and also to run "pingplotter" or "mtr". Networking says the Cisco switches appear to be fine. For the Rays in this report, there is only a single (Cisco) switch stack between server and client. To use the Ray 2, we moved the server (X4200 running Solaris 10) to a 100 Mb/s line. There are many posts on this very issue, including problems noted by Sun with Gb-to-100Mb downsizing, with the blame sometimes going to switches for dropping UDP packets. The arrangement vastly improves packet loss on the Ray 2, but does not help the Ray 1. To be fair, the Ray 1 functions perfectly if we wire directly to the server via a $50 Netgear GS108 switch. We also have very good performance if we wire through a router (an ordinary Pentium III with two 3com 905 interfaces), even though this routes over the same wire where we have packet loss when connected directly. --Darrel Hankerson _______________________________________________ SunRay-Users mailing list [email protected] http://node1.filibeto.org/mailman/listinfo/sunray-users
