P4000 management using 2910al's?

[Paul Hutchings]

I'm going to be putting six P4000 nodes into a stretch cluster over the next month or so.

I have 2 2910al switches, one for each location, which are to be dedicated for iSCSI traffic (and perhaps vMotion too).

I don't want to sacrifice 50% of my NIC count on management NICs to plug into my production LAN, but I would like to be able to manage the P4000 via CMC from my production LAN.

One option is to have a management VM which has NICs on both networks.

Another option is to use VLAN's and IP routing on the 2910's, but I'm not sure if there is any inherent danger in routing between networks - I'm not sure if the 2910 will let me do ACL's to only allow management PC's through.

Could I get some advice on the recommended way of doing this please as there doesn't seem a "right" answer, it almost comes down to "what do most people do in this situation".
