We are upgrading a 3 host VMWare setup (ESXi 5.5) from Essentials to Essentials Plus which gives us the added benefit of vMotion etc. Due to the limited number of 10Gbps NIC's I am unsure where to put vMotion?
Based on the attached network diagram I am considering the following options,
1. Put vMotion on the two aggregated 1Gb NICs that are also used for Management traffic (green).
2. Put vMotion on one of the ports on the Dual port 10Gbps NIC's (yellow) with the other as a failover adapter (purple).
My concern with option 1 is that vMotion failover/migration won't be as quick as option 2.
My concern with option 2 is that vMotion traffic will negatively impact iSCSI traffic.
Which option would you recommend and why?
Note: iSCSI between ESXi Hosts the High Availability Storage Cluster uses MPIO Round-Robin.
