8.2SCSI hard disk drives

The server is equipped with four ultra 3-wide U160 SCSI hard disk drives. Each of the SCSI hard disk drives are mounted in slide-in modules. The drives are externally accessible at the front side of the server and connect to the SCSI backplane via the SCA (single connector attachment) interface. This allows that the drives can simply be inserted or pulled out (hot-plug). As part of the hot-plug implementation, a drive slide-in module with integrate heat dissipation is required. The drives are mounted in the slide-in module with fasteners and the slide-in module snaps into the chassis with a locking mechanism.

The hard disk drives can be controlled either by the dual onboard SCSI controller (default) or by a RAID controller (add-in board in a PCI slot).

If a SCSI hard disk drive is operated on a RAID controller and belongs to a disk array operated with RAID level 1or 5, a hard disk drive can be swapped during operation (hot-swap). To swap a hard disk, you need a hard disk drive with the same or higher capacity. A rebuild on the new hard disk drive is performed automatically after the swap, provided the RAID controller is correctly configured. Refer to the information in the RAID controller manual.

IIf the hard disk drives are connected to the onboard-SCSI controller (default), the system must be turned off before exchanging a hard disk drive.

So that the storage capacity of the hard disk drive can be recognized at a glance when the hard disk drive is replaced, several prefabricated stickers with the storage capacities are provided with the server. Each hard disk drive (slide-in module) should bear a sticker indicating its capacity on the front. Should no suitable sticker be available, blank stickers for labeling are also provided. The stickers are color coded for easier identification.
