All four ports are coming up as Intel e1000 ports. Is there any way of telling from inside the OS which exact port eth0,1,2,3 actually are? Ive seen RHEL change port around before, and I was just wondering how to check which interface corresponds to which physical port, as this will probably be important when we implement it.

I want to compare the read/write speed of local vs SAN storage, while the machines are in use. However the chances of getting to do it in the live environment are zero. If I can keep the memory usage at about 85% [cpu load is about .4 so is pretty negligible] I would have some data to look at.

MAC addresses mate. You will be able to tell from the BIOS which cards
have which MAC addresses, then lspci, ifconfig and udev are your friends
to make sure that
you don't run into the NIC enumeration issue.

I can send you my udev rules later if you like, busy right now :-)
