Network question for new Vsphere 5.1 Datacenter

Hi guys,

I hope you can give me some advise for a active/active network concept.

Each physical datacenter will get 2 ESX Hosts, 1 NetApp 3220 Filer and 2 stacks of each 2 Cisco 3750 switches

(one stack for the storage network, one stack for the clients).

The hosts are diskless, they have 2 sd-card slots for the esx hypervisor. The scratch disk is on the NetApp.

Here is what I have in mind:

- 4 physical nics for the connection of the client network (VLAN 50)

- 4 physical nics for vmotion, NFS and ISCSI (VLAN 100)

- 2 physical nics for the management network and service console (VLAN 101)

What are your thoughts?

Thanks!
