Dell PowerEdge 750 / RedHat 9 / e1000 Driver Network Issues
I currently have 30+ Dell PowerEdge 750 Servers all Running RedHat 9,
using the e1000 driver that comes with RedHat 9. On bootup I see that
I am currently using Driver 5.2.52 of the e1000 driver, also I see
that links up at 1000 Mbps Full Duplex however whenever I try to copy
a 500 meg file between the 2 Dell Servers I am lucky if i get 4 Megs/sec
which is not acceptable. I have tried also upgrading to the latest Intel
driver with no different results. I seriously need this issue resolved
as it is affecting my performance greatly.

Sometimes a driver is the issue. This is the latest Intel driver in a DKMS package provided by Dell.
ftp://ftp.dell.com/network/Intel_LAN_8.2_RHEL3_DKMS_A01.tar.gz
Other times it is a network problem. To test, I would connect to hosts using the driver above on a dedicated gigabit network using cat 5e or cat 6 cables, w/ nothing else on the network.

if you do an ifconfig you will see for every 3 packets 1 packet with crc error.
i think you are using the 'old' e1000 driver (before 6.2.15) this will cause the problems. so, go to the intel web site and download the latest e1000 driver (e1000-6.2.15.tar.gz) and compile it.
the new driver will speed up the network from 8MByte/min to 80MByte/sec, tested on mandrake 10.1 and fedora core 3 on a 750 running backupexec agent.
good luck
