I am in the process of planning the virtualization of my infrastructure (better late than never).
My servers consist of
- Domain Controllers
- Exchange Servers
- SQL Servers
- File Servers
- Anti-Virus Servers
- SharePoint Servers
The new environment will consist of a 3 node Hyper-V cluster connected to an iSCSI Dell SAN.
My question is about how to configure the SAN in terms of Best Practices.
1.
Should I split the SAN into equal LUNs e.g. 10 x 200GB and present them all from the onset. Or should I only create LUNs for the storage I need now e.g. 5 x 200GB, and leave the remainder capacity unallocated?
2.
Should I create different RAID types and store the VHDs according to requirements e.g.
LUN 1 : RAID 1 : store File Server OS VHD
LUN 2 : RAID 5 : stores File Server DATA VHD
or should a VMs VHDs all be stored on the same LUN and/or same RAID type (RAID 10 perhaps?)
3.
Is it beneficial to create numerous smaller LUNs and present several CSVs to the Hyper-V hosts or should I create a single larger LUN and present one CSV for all virtual machines?
4.
I plan to leave the virtual Domain Controller on local storage as my understanding is to not cluster it.
5.
Any other Best Practice tips for Hyper-V SAN configuration.
