Best use for network cards

Hey guys

We are gearing up to deploy a new VMWare environment. Until now, i have always used physical boxes and NICs have not been a problem and I've mainly played with the free versions....

This time were going paid.

We have Dell blades to use with pass through modules, with 5 network cards per blade, all Broadcoms running at 1GB pass through to 2 physical HP switches (no switches in the blade chassis).

I'm trying to work out the best use of the network cards

We will have 3 hypervisors with a iSCSI SAN.

I was thinking:

2 NICS (Active / passive 1 to each of the 2 switches) for storage

2 NICS (active / passive 1 to each of the 2 switches) for VM Network and management

1 NIC vMotion

I could add a 6th NIC in to allow 2 NICS to each service (active / passive to each of the above)

I would love your thoughts on my idea, as i can see a few ways to do it, and im not sure what would be the best

Thanks!

For those that stumble across this

We ended up doing

2 NICs to data

3 NICs to management / vmotion / SAN

Using 3 way multipathing for the SAN on the NICs favouring the NICs in different needs

We used distributed switches
