Re: SCSI Question

The disks should generally be the same size(and also the same speed, etc.), though you can add a disk that is larger without issue - you'll simply lose the extra space on that additional disk.

Should you have a disk failure, you simply pop out the old disk and pop in the replacement. HOWEVER, during the rebuild time, your server will be significantly slower as the array gets rebuilt. This is especially true in a RAID5 array.

Whether your controller supports hot spare will depend on the particular controller. Most do. That spare will not provide redundancy until the rebuild is complete, but the process should start automatically upon failure of a disk in the current array.

I have SBS 2003 installed across 5 disks. It is a Dell server 2600 whose Perc controller / configuration created a stripe / RAID 5 array across these disks.

Question:
---------

(1) If one of the disks goes bad, do I just replace the disk? Or is there are option to create a hot spare BEFORE creating the RAID 5 stripe - so I could just replace the disk?

(2) Do the disks have to be the same size? In what instance does it need to the same size?
