Vmware vCenter datastores and hosts design

I am working on a new vCenter environment with 6 hosts and a Cluseted NAS storage (24 TBs) with a 20Gig backplane.  This storage will only be used for VMs.

My basic design is to have 3 datastores, each datastore dedicated to a pair of clustered hosts. As we add on more hosts in the future they will be add to one of the 3 host clusters.

Host 1 & 2
Datastore 1
VMs - Windows Applications Servers (File Servers, Terminal Servers, etc.)

Host 3 & 4
Datastore 2
VMs - Windows Servers (DC, DNS, etc)

Host 5 & 6
Datastore 3
VMs - Windows SQL Servers

I would like some best practice advice or recommendations on designing the datastores with the current hosts.  Should I create two datastores per host cluster or will one be sufficient. Is there anything I need to consider regarding vMotion or host cluster design?

Any help will be greatly appreciated.

Thank you.

This seems like a waste of resources if you ask me. For the hosts I would reccomend putting all 6 into the same cluster then enabling the HA settings. This way you will have redundancy if there is ever an issue.

If you really wanted to set certain guests to run on certain hosts you can do this with affinity and still maintain better HA with a 6 host cluster.

For the datastores I would present all 3 of them to all of the hosts and possibly create a storage pool depending on the RAID config, drive types that comprise your datastore.

Vmware is very good at resource allocation I would say to let it handle it whenever possible.

Thank you! I see I was definitely planning a short sighted VMware infrastructure. Great suggestions!
