Overview of Disk Drives
The NonStop S-series server supports:
•
External Disk Drives
•
Internal SCSI Disk Drives
•
M8xxx Fibre Channel Disk Drives
•
Enterprise Storage System (ESS) Disks
A system enclosure can contain different types of disk drives. However, both disk
drives in a mirrored volume must always be the same type of drive.
External Disk Drives
External disk drives connect to a NonStop S-series server using fiber-optic connections
provided either by a 6760 ServerNet device adapter (ServerNet/DA) or a Fibre
Channel ServerNet adapter (FCSA). For more information about ServerNet/DA, refer
to Section 7, ServerNet/DA: Monitoring and Recovery. For more information about
FCSA, refer to Section 8, Fibre Channel ServerNet Adapter: Monitoring and Recovery.
Enterprise Storage Systems (ESS) are supported externally through FCSAs.
Internal SCSI Disk Drives
Internal disk drives are housed in disk drive CRUs installed behind the door on the
appearance side of a system enclosure. (See Figure 9-1.) Each system enclosure
contains slots for up to 16 internal disk drive CRUs, arranged in two rows. The slots
are numbered 01 through 08 in the upper row and 11 through 18 in the lower row.
