We recently purchased a Dell PowerEdge M1000e Blade Server with 4 Cisco 3032 Blade Switches.
We have 2 4507 core switches.
The Blade Servers will have multiple NICs that may or may not be on separate VLANs. For example:
Server-1 NIC-1 will have IP of 172.17.4.20 NIC-2 will have IP of 172.17.5.20 and NIC-3 will have IP of 172.17.102.5
Server-2 All NICs will have IP in 172.17.100.0 255.255.252.0 netowrk
Server-3 NIC-1 will have IP of 172.17.4.30 NIC-2 will have IP of 172.17.6.00 and NIC-3 will have IP of 172.17.102.20
I have a total of 4 Cisco 3032 Blade Switches that I want to trunk and channel to the 4507's in a failover design that if I lose 1 of the 4507's or a 3032 I will not lose connectivity to any of the Blade Servers.
Would appreciate a discussion on the best design for this.
There's a good whitepaper on Cisco blade switches and the Dell enclosure here:
