SATA Drives on Backup Server

I need to replace our current backup server.   The corporate sever spces contain a server which will work for the backup server.  The only thing which has me concerned is that they have specified I have to use SATA drives instead of SAS.  

I will be running Backup Exec on WIndows Server 2008 and using it to backup remote servers to tape.   Will the SATA drives on the backup server make a difference in the  throughput of remote servers?

Yes, it will make a difference.  SATA disks aren't dual-ported like SAS drives.  They don't have nearly the queue depth or random I/O performance that SAS drives generally have, and many don't compare with SATA drives when it comes to data integrity and the # of ECC bits.

There are some enterprise class SATA disks, but due to these other limits, you should question the wisdom of choosing SATA drives.  Backup systems need to run enterprise class disks and the correct firmware QUALIFIED for the RAID controller you are running.   If/when something gets lost or munged in the temporary pools before getting streamed to tape then it will likely be your job on the line.  

Frankly, I'd have a polite talk with whomever said to just use SATA drives and get their reasoning .. only reason I can see somebody wanting to use them for a backup server is if they wanted to back up old IRS records that need to disappear ;)
