asked on using RAID 5 or RAID 6 for Large Exchange 2013 Mailbox LUN
Hi Folks,
For the Mailbox Server role in Exchange Server 2013, which RAID is best to be used ?
RAID 5 or RAID 6 ? I will provision 1.5 TB for holding 750 Mailboxes.
This will be implemented as VMDK (VMware) not a physical RDM presented to the Virtual Machine.
My assumption is that the Data and Logs are hosted on top of this RAID type but on different Virtual SCSI controller (pvSCSI).

Why RAID vmdk disks?

well the RAID 5 or 6 is the question here, which one should I choose over speed ?
I know that the new version of Exchange does not need to be deployed on top of RAID10 or SAS disk due to the lower I/O requirement.

Do you want to be protected by 1 (RAID 5) or 2 (RAID 6) disks failing?

Well if that is the case I can just deploy it on RAID 5 because the mailbox server is clustered with DR sites As VM :-)

As usual, the Exchange 2013 Mailbox server role is deployed with Database Availability Group between Production and DR site.
