Overview of Disk Drives

The Integrity NonStop NS-series server supports three types of disk drives:

•

•

•

Internal SCSI Disk Drives

M8xxx Fibre Channel Disk Drives

Enterprise Storage System (ESS) Disks

Internal SCSI Disk Drives

Internal SCSI disk drives are installed in NonStop S-series I/O enclosures.
