vSphere 5 Host Network Design - 10 NICs Segmented Networks
An isolated storage network is still my preferred option in almost every environment. Isolating storage to a different physical network would allow up to 12 hosts to be connected across 2 x 48 port switches.
It is assumed that you will be using a separate management cluster for vCenter and associated database or that your vCenter server and database are located on physical servers.
* 1 - Distributed virtual switches require Enterprise Plus licenses. This design really calls for Ent+ licensing as the fail over policies are quite complex and manually configuring these across multiple hosts is almost guaranteed to misconfigured. I would not recommend this design for organizations that do not have access to distributed virtual switches.
* 2 - This vMotion port can be used as shown in the design or if you need a greater number of FT protected VMs then simply change this port to a FT port. Make sure to configure load balancing policies so that FT traffic does not interferer with the Management network.
* 3 - Route based on physical NIC load is a policy only available in a dvSwitch. If you do not have Ent+ then use the default policy instead.
* 4 - Datastore path selection policy is typically best set at Round Robin, but always consult the storage vendor documentation to confirm the best type to use.
