Need optimal RAID configuration for existing hardware for Exchange 2010 install
Posted on 2011-09-19
I have (2) new Dell R510 servers to be used for Exchange 2010. I will have the mailbox, CAS and HT installed on both servers and will configure DAG. Currently have about 750 mailboxes at a total size of under 100GB. Each server has (2) 146GB 15k SAS drives and (10) 1TB 7.2k SAS drives. I know I will use the (2) 15k drives in RAID 1 for the OS/Exchange, however I want recommedations on the optimal configuration for the rest of the setup. Should I put the logs on this 15k RAID 1 as well? Should I do multiple RAID 1's and put the DB/Logs on them together, breaking the mailboxes up into 4 or 5 different DB's? Should I do 1 large or 2 smaller RAID 10's? Should I keep some of them for hotspares and not use all 10?
Experts, please provide your optimal setup with this existing hardware.
