Back on the Kernel list after a long hiatis. Need some experienced
optinions.

Current Setup:

Linux Legato Backup server  (E1000 nic)   Linux-2.4.19-pre4
5xLinux NFS servers         (E1000 nic)   Linux-2.4.19-pre4

Legato mounts the NFS shares over a Gig ether and uses them as backup media for non-offsite/non-longterm. This works very well when NFS behaves.

The probems is that every now and then the network/nfs just hang up for a while and gets VERY slow. Some research has been done and it seems that the PCI latency is part of the problem, especially when IDE Raid hits the disks hard, this can overrun the buffers on the GigE card.

I've got a test NFS server coming in and will look at upgrading the kernel to 2.4.19-pre11 as there were some bugs associated with E1000 and NFS I saw in pre-[7-9] area. I'm also considering trying to use Network Block Device instead of NFS. Has anyone tried this?

Any suggestions that doesn't involve hitting up a non-existant budget?

Robert

D-Link dfe-580tx (nic of doom)

......So did anyone ever get this 4 port nic to go under linux?
I booted it up with a fresh copy of RH 8 this morning and still no joy. I even tried to compile the newest version of the sundance code, but no fun (couldn't even get the darn thing to compile). Can someone point me in the right direction (working binary rpm would be nice) or give me a quick run down on how to get this thing going????

You need the latest driver, patch attached.

Have you increased the e1000 Rx and Tx descriptors?

Could try the e1000 NAPI patch as well...
