Hi,

I'm currently running Exchange 2007 SP3 on Windows 2003 so I'm starting the process of migrating to Exchange 2013. Our current Exchange 2007 configuration is very small with 31 users and an Exchange mailbox size of around 100 GB right now.  Our current Exchange 2007 box has a Xeon CPU with hyper-threading so I've got two CPUs and it has 6 GB of memory. I've got two Raided drives for the C and D with the Exchange 2007 software and mailbox on the D drive. The performance of this server is adequate though it's beginning to get a little slow.  We also have an SCR replica server that is virtualized.

So I'm trying to figure out what would be an appropriate new server size should be and I've looked at all the server sizing information and looked at the Microsoft provided sizing calculator workbook but even the smallest example is for a server with 1000 users which is clearly way more than what I have.

Given what I've read, I was going to go with the following hardware:

- New very fast Xeon CPU with at least 8 cores

- 16 GB of memory, possibly 24 GB

- Raided drives for the C, and D, and possibly an E drive to separate the database and log files. Probably 250 GB for the OS and 1 TB each for the data drives.

Any thoughts on this?  Also if anyone has any links for sizing that are a little more specific to smaller deployments that would be very helpful.

Thanks

Nick

Nike,

CUP & Memory (24GB) should be good as you only have very few users to handle.

On the Disk, Make sure they are Fast & The recommended RAID configuration for mailbox drive is RAID-1/0 

I would recommend you to take a look at the below links

Hi Shekhar,

Thanks for the reply.  I'm going with RAID 1 for the OS drive and then RAID 10 for the mailbox drives.

let me know if you need any more help

Ok thanks I'll check it out.

Pretty much decided on a Dell T320 with 24 GB of memory, 8 core CPU and RAID 10 drive setup for the mailbox drives. Given our current hardware and Exchange performance this should be more than adequate and give us some room to grow if we need to.

Create Raid 1 for logs

Really RAID 1 for the logs?
