eth0 goes to fabric A1 eth1 goes to fabric A2 You need to verify which riser your 10Gbit NIC is in. The blade has 2 PCIe riser slots; B and C. B goes to the B fabric and C to the C fabric. If you put the card into the B slot, but your M8024 is in the C-fabric, you wouldn't get much use out of it. Also; do I understand you are looping your passthrough ports to the switch in the B-fabric? It's possible, but it makes little sense to me; I'd plug the passthrough ports into a rack switch.
Hi there I'm trying to configure Ubuntu 11.10 on a M710HD which is in a 16 slot (half height) PowerEdge M1000e rack enclosure. The rack enclosure has 1Gb pass through module in Fabric A, and as I understand it each port on tis module maps to a slot in the enclosure. Fabric C is filled with 10Gb M8024 switches, that connected to 8024F switches where our Equallogic SAN is also connected. Finally Fabric B contains M6348 switches. On the Ubuntu side, I can see four network devices - eth0 and eth1 are on the same PCI bus address and both identify as NetXtreme II BCM5709S Gigabit Ethernet. eth0 is then the pass-though 1Gb (which connects to one of the M6348 switches and then onwards to our LAN). I'm not sure what that second port on the Gigabit Ethernet is meant to be (eth1) - would that be connected if we had a second pass through module in Fabric A? Then eth2 and eth3 identify has 82599EB 10 Gigabit Dual Port Backplane Connection. If I run a tcpdump on them, I can see some STP traffic initiated from the device's ethernet address, but nothing else, and more importantly, I cannot seem to ping any of the other devices that I know are on the 10Gb network that we have installed. So, I'm presuming that the network topology is as follows: M710HD 10Gb <-> (internal port) M8024 switch (fibre)  <-> 8024F switch (fibre) <-> SAN Is this correct? And if it is, then any idea why I can't seem to connect to other devices? My next step is going to be to install Ubuntu on a second blade and see if the two blades can see each other, so I have an idea at which point the problem is occurring. In the meantime, however, if anyone has advice, I'm all ears! Thanks! Peter
