Network configuration with only 4 NICs

I have 3 HP Proliant servers DL360 with 4 nic interfaces each.  Planning to use Hyper-V servers 2012 R2 as hosts and HP VSA as shared storage for some of the VM's.


Solution needs 8 NIC's for best reliability and perfomance, but i have only 4. My plan is:

2 NICs for VSA and iSCSI. Using Hyper-v VSwitch i'll create two virtual NICS - VSA and iSCSI on each of two physical interfaces. VSA and iSCSI would be on separate VLANs, but on same physical NICs.

2 NICs for everything else (VM's LANs, management, migration) separated by VLANs.


Each server would be connected to two physical switches for redurancy.


Or should i use:

1 NIC for VSA

1 NIC for iscsi

1 NIC for VM's

1 NIC for migration?

Without redurancy on switch and ethernet ports level, but simpler. I could add network adapter later.


In first case should i use HP Network teaming to combine two physical NICs, or i should use any other technology?

What are the best practices both for 4 NIC's and for 8 NIC's cases. There is a network plan on page 16 of best practices guide but i'm not sure if i do understand figure 11 and figure 12 right.
