Our Server admin and i have been trying to figure something out. We currently have a IBM H series bladecenter with 6 bladeservers that have two NICs. We have two of the CIGSM switches in the chassis. Each server NIC connects to the two switches individually. We're looking to add two additional NICs using the Ethernet Expansion Card for bladeservers. If i add two more NICs (4 total) will i need 4 of the CIGSM switches in the chassis? One switch to every NIC? I know this more of an IBM question but we can't seem to find any answers to this.
Solved! Go to Solution.
By default each IBM blade comes with 2 NICS and if you want to have 4 NICs in each blade, then you need to add an expantion card to each IBM blade. This way you will get 4 NICs and you can etherchannel all of them together. we have this exact configuration in our data center
but each NIC connects directly to a seperate Cisco switch. How can you configure an etherchannel on a bladesever that connects several seperate switches?
I'd like to bring this topic back up again. We've decided to move forward with purchasing an additional 6 Cisco 3012s
in addition to the 2 we currently have, so a total of 8 3012s. That means all 8 of our Bladeservers willl
have 8 NICs as well. You said I could configure an etherchannel on the 3012s using LACP. We are running vSphere 4 on our chassis. Could you give me some more details on the design with VM Ware involved? Right now we have 2 NICs per bladeserver w/ 2 3012s. in VM Ware, each NIC/Uplink is configured in Active/Standby mode. How would we configure this for Active/Active?
Could someone elaborate on this a little more? I can't find any information ANYWHERE about having active/active NICs in vmware on a IBM BC with cisco 3012s. We have now installed 8 nics per bladeserver and 8 cisco 3012s in our BC. Each pair of NICs/switches are configured for Active/Standby. To my knowledge you can't team them because you can't have the same ether channel going to two seperate switches. Can someonme confirm?
