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

DISCLAIMER:
These are MY OPINIONS ALONE. I speak for no-one else.
FYI:
perl -e 'print $i=pack(c5,(41*2),sqrt(7056),(unpack(c,H)-2),oct(115),10);'
......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????

Have you increased the e1000 Rx and Tx descriptors?
Could try the e1000 NAPI patch as well...
