I am encountering network performance issues, which I believe may be related to network drivers. I am observing an unresponsive network configuration on a Sol 10 host configured with 3 whole root zones. Outside connections to global and non-global zones are demonstrating 'lag' time when connecting with ssh, telnet, or remote dtlogin. Internal connections from any zone to another are equally impacted. In a current configuration, pings from zones are dropped. What makes this a bit more confusing is that different hardware platforms display a wide range of performance charactoristics, from no issues with lag time observed to extremely long response times.
I've configured three servers, ( a v240, a 220R, and a v880), with very similar whole root zone configurations and each displays different network responsiveness. The configuration involves initial installation and patching, a single shared interface, all zone ip addresses on same subnet, and all zones have netmasks, default router, and dns configured. Each system has a very light load because of early stages of installation. The 220R with its internal hme port is very responsive, no problem at all. I can ping each zone internally, I can remote dtlogin from global zone to non-global zones, ssh and telnet work as expected. The v240 with its bge port configured is significantly worse. remote dtlogin from global zone connectivity is intermittant requiring several attempts to login. ping, ssh, and telnet display a 'lag' time. The v880 non-global zones, with the eri port is very unresponsive and almost unusable. telnet and ssh demonstrate significant lag time. remote dtlogin from global zone is impossible. I've found references to bge driver issues and bge driver patch, but nothing for the eri driver. I'd like to collect information but would need suggestions on DTrace scripts that would shed light on the issues. Any suggestions? _______________________________________________ opensolaris-help mailing list [email protected]
