Greetings everyone, I'd like to know if it is possible and advisable in my current Exchange Server 2007 SP1 with CCR technology to consolidate the following: 10x Storage Groups Replicated which each consists of: 10 Drives for each Mailbox Database - RAID 5 @ 150 GB 10 Drives for each Mailbox Transaction Log - RAID 10 @ 60 GB into just: 1 Drives for new Mailbox Database - RAID 5 @ 2 TB GB 1 Drives for new Mailbox Transaction Log - RAID 10 @ 1 TB The total number of mailboxes is 700+ users, so what is the implication and caveats in consolidating into the new proposed scenario ? Any kind of advice would be gretly appreciated. Thanks,/* Server Support Specialist */

Hi! It all comes down to the amount of IOPS you are going to chase through these disks. Remember that having a RAID 5 array, requires you to have at least 3 drives. For RAID 10, you at least need 4... Is it possible? Yes; but that depends on the type of hardware and the load you're going to put on it. You said 700+ mailboxes? Is that around 700 or potentially even 1000? Also, take into account that larger databases take longer to backup/restore. Having a 2TB Database doesn't really strike me like a good idea either...

Michael, Thanks for the explanation, yes you are right, I guess the reason it is better to be divided among 10 Storage Groups and each individual Drives is for the backup reason. /* Server Support Specialist */

Hello Albert, As Michael mentioned the answer to you question will be yes, But the important is your IOPS and disk Performance to handle the load. you can also have a look at the Storage Requirements Calculator Exchange 2007 Mailbox Server Role Storage Requirements Calculator http://blogs.technet.com/b/exchange/archive/2007/01/15/3397742.aspx Please let us know if you have any questions.
