Hoping someone can give me an idea of what it takes to do this. I am starting off with a 4 x 73 GB 10K SAS drives. I will be configuring them in RAID 10. In the future I plan to upgrade these to larger SAS disks. My question is when upgrading, is it possible to just hot swap them one a time giving time for them to replicate, or do I have to ghost an image of them, then restore the image once I have the new drives installed?
