question concerning disk quantity for 1400 mailbox users

[blade1000]

Hello-

I am to migrate 1400 users from nds to windows 2008 R2, -this I have no problem handling.

I then need to assess my quantity of disks needed for all 1400 users pertaining to 1400 mailbox servers.

Is there a better method other than using the Exchange 2010 storage calculator sheet for this?

I just need to know how disks I will need total if I need 1400 mailboxes, the drives will be 300GB each, 15k rpm fiber.

Is there a proper formula I could implement on paper just to give me my total # of disks needed?

thanks for any help here

You really need to use the storage calculator since we aren't concerned so much with space as with IOPS.

Theoretically if each mailbox was only 2GB you could fit all your users onto 1x300GB disk but the performance would be execrable.

Also depends whether you intend using RAID5 (not recommended), RAID10, JBOD (if using min. 3 node DAG) etc.

You could also use the HP Exchange 2010 calculator which asks for similar stuff but looks a bit nicer.

When properly planning with Exchange 2010, you should be neither capacity constrained nor performance constrained if you do it correctly. It should be fairly even.

As ntinlin says, you really should use the storage calculator.

Plan for performance, and capacity takes care of itself. Plan for capacity, and suffer poor performance.
