I have a new server, that is running MS Server 2008 R2 and am preparing to deploy Exchange 2010 Standard on it. I have approximately 70 mailboxes. We don't do a lot of hiring so that number will stay steady with possibly a growth of maybe five mailboxes at maximum.
I will be migrating over our 2003 mailboxes once the 2010 server is up and running. The existing 2003 database is approximately 50 GB's and we have been running this server for about 2.5 years.
My new server has six hard drives, 2-146GB drives and 4-300GB drives. My plan is to RAID 1- 146GB drives, with two partitions, one for OS (75GB) and one for transaction logs (about 55GB).
For the 300GB drives, I plan on using 1 as a hot spare, and 3 for a RAID 5 array. On the RAID5 array there will be two partitions, about 200 GB for an IT share point, and the remainder about 600GB for the Exchange Database.
I would just like some input / reccomendations on my proposed partitions.
Also I would like some advise on setting up the transaction logs. Circular logging vs. Log Truncation. From my understanding the backup program we use (Barracudaware Server) has an Exchange agent which backs up the logs nightly after the changes have been commited. Can you please offer me a little more insight and advice on which logging method to use?
