Select a workstation that has Gb NIC and connect it to a Gb port on the switch. Stop all traffic into/out of the blade server and the workstation. scp a Linux DVD iso file to/from the blade server and the workstation and watch the xfer rate; it should be close to 120 - 125 MB/s (1000 Mbps/8). I don't have a Gb switch; on a 100 Mbps switch, I get close 12 MB/s xfer when I do a similar test as above. You can also install iftop on the workstation and watch the xfer rate there as well.
