Disk Support

The preponderance of SATA (Serial ATA) drives and their penetration into the server market means that most 1U servers are equipped with SATA by default. SCSI--the other choice--has strong supporters and strong detractors. However, the performance and reliability differences between SATA and SCSI aren't as many as you might believe. SATA drives are great for your system if your business data is on remote disks and you have many nondatabase applications. But for high-volume work, SCSI performs better. On the other hand, SCSI is more expensive. Don't pay for that technology unless you are certain you need the speed.

If you decide on SATA, you'll need RAID support. SATA works best in a RAID 5 environment. With SATA and RAID, you may no longer care about the SCSI-versus-the-world issue, but if you do, ask about support for SCSI also.


There haven't been many changes in memory technology lately, at least not in mainstream servers. As a general rule, make sure there's at least one empty slot when you purchase the machine. This will give you some room to expand without having to completely replace existing chips.
