We have an Exchange 2003 server running on Server 2003 STD SP2. It is running out of disk space on the current RAID array. The array is on an Adaptec 2130S SCSI controller, all drives are 300GB.
Drives 0&1 are mirrored for the OS
Drives 2-5 are in a RAID 10 for the stores (558GB total 33GB free)
What we want to accomplish is build a new array on a new controller (Adaptec 5805Z & Seagate Cheetah 15K.7 SAS-2 drives) and restore the OS and Stores using Acronis. I have done this several time in the past to upgrade RAID configurations with much success. My question is is this process possible with Exchange 2003 since we used the Diskpar utility on the current drives/array? Does anyone know if the disk backup and restore process keeps this disk alignment? We definitly do not want to degrade the performance of our Exchange server by upgrading the RAID controller and drives. Or does anyone know a better way of doing this with Exchange?
