Server connectivity options for Storage

[nayanpanchal]

Dear Gurus,

We have existing servers in our environment with HBAs and NICs. We are not planning to use Unified fabric (CNA etc) based architecture. We want our storage network to be separated from IP network.

However, can I connect HBA of my servers to FC SFP in FEX or Nexus 5Ks. If yes, how would be the subsequent connectivity towards SAN switch.

Any pointer would be greatly appreciated. Thanks in advance.

N5K can be configured to work as a pure Ethernet, pure FC, or hybrid FC/Ethernet switch support native FC.

see eg. https://supportforums.cisco.com/thread/2236539

FEX doesn't support native FC !

From N5k, you can create ISL links to a FC fabric, be it MDS,.....

Here a list of N5k FC features; what is not supported is IVR ! BB credits are 240 !
