-Packet monitoring on a dual port intel gigE addon controller. -occasional Cifs/LDAP/http traffic on embedded port 0. -MTA on embedded port 1. -Custom TCP app on embedded port 2. -Custom app via lighttp server (https) on embedded port 3. -Occasion heavy cpu and disk activity on system. (load average will hit 8+ for several minutes.) Most of the network traffic is fairly moderate with occasional heavy spikes. We're generally not in the GigE range unless we are spiking. > 2. whether or not the problem can be reproduced with the NIC > drivers > from support.dell.com. Never thought to look at the driver as we were up to date with Red Hat. A non-distro driver is hardly maintainable long term. We'd end up recompiling the drivers for every Red Hat kernel errata update, and hope that the driver keeps working. Really how many customers in this day and age expect to need to go to the support site, download, figure out what you need to do, setup a box able to build the rpm (we only use RHEL on servers, and servers don't compile things), and build the rpm. I'm also wondering obvious disconnect between Dell, RH, and the mainline kernel with the bnx2 driver version. -Dell support site ones are version 1.8.7b -Red Hat's kernel 1.7.9-1. -linux-2.6.30.1 2.0.1 That said there are some interesting things in RELEASE.bnx2.TXT, but nothing that jumps out as the fix. > 3. whether or not the problem occurs if the bnx2 module is > loaded with > the disable_msi=1 option. > 4. the iDRAC settings for the options "iDRAC6 LAN" and "NIC > Selection". In any case of the R710 systems I have. The "slow" cpu box is in pieces, and the "fast" (X5570 cpus) system is back in testing with 3 intel dual port controllers. It will take a long while to test these due to the length of time the issue takes to reproduce. (Plus I need to steal some nics from other systems or buy more...) As far as the IDRAC settings. Is there any way to get that info without a reboot? _______________________________________________ Linux-PowerEdge mailing list [email protected] https://lists.us.dell.com/mailman/listinfo/linux-poweredge Please read the FAQ at http://lists.us.dell.com/faq
