I saw a Serial SCSI on a HP Proliant server, what is this exactly? Is this the server's Hard disk or some sort of external storage device?

Hi Aspire, serial scsi is the technology that replaced the old parallel scsi standard that we are all used to. Most commonly serial scsi is used in server’s serial attached scsi drives, also known as SAS drives. These hard drives are very common in brand new servers. Serial scsi is a standard for data transfer just like parallel scsi was. It is considered the norm now and the standard is getting faster and faster. You can read a bit about it at this link.

    I believe what you are seeing is a RAID 5 configuration. Remembering that the actual usable value of an HDD is somewhat less than the stated capacity (i.e. a 73GB drive may give you 68 - 69GB (+/-) of formatted capacity), and that in a RAID 5 configuration, the total capacity of one member drive is lost, 68 * 3 -68 = 136. You want to leave this setup just the way it is.....
