We are are a single site, single domain with 70 users. We still run our servers in house. I have a dedicated server running Exhange 2010. It's a Dell Powerdge T430 with 32GB RAM and 5 SAS disks on a single H710 controller card. One channel runs 2 x 136GB disks in a RAID 1 array that contains the OS, exchange program files and the logs. The other channel runs 3 x 300GB disks in a RAID 5 array that contains the information store.
The server is 4 years old now and i am planning to replace it in the next few weeks. When i get the new server i will be moving to exchange 2013. Why not Exchange 2016 i hear you ask? We only have CALS for 2013 and as this is probably the last exchange server we will have in house before moving over to the cloud it doesn't make sense to upgrade the licences.
I would appreciate some advice on the disk configuration...
