Uplink ports should all be configured to use PortFast.
Both the storage uplink ports and the virtual switch used for storage should be configured to use Jumbo Frames by specifying an MTU of 9000.
In this design trunking should be configured on all uplinks. Trunking at the physical switch will enable the definition of multiple allowable VLANs at the virtual switch layer.
It is assumed that each host has a dual port internal NIC and quad port expansion card. So vmnic0 and vmnic1 are inbuilt and vmnic2 through vmnic5 are PCI-X.
* 1 - Distributed virtual switches require Enterprise Plus licenses. If you do not have Ent+ then replace these switches with standard virtual switches.
* 2 - 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.
* 3 - VLAN tagging for the storage network is not required as it is isolated but is still a good idea as it keeps networking configuration consistent and is not very hard to implement.
* 4 - VLAN 30 is reserved in the event of Fault Tolerance being added to the design at a latter stage. Always reserve VLANs that may be used in the future as this will save you time and effort later on.
* 5 - 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.
