About Internal Disk Drives

The Sun Enterprise 220R server supports up to two internal, hot-pluggable UltraSCSI disk drives. Drives are 3.5-inches wide and 1-inch high (8.89-cm x 2.54-cm).

The drives are supported by the 40-Mbyte per second UltraSCSI interface on the system’s main logic board. Both drives plug in to the two-disk backplane, which mounts to the back of the system’s disk cage.

On the right side of each installed disk drive is a green indicator LED. These LEDs indicate the operating status associated with each disk drive. For additional information about disk drive LEDs, see “Disk LEDs” on page 142.

The following figure shows the system’s two internal disk drives and LEDs. Disk drives are numbered 0 and 1, with the 0 drive the default system disk.

The Solstice DiskSuite software supplied with the Solaris server media kit lets you use internal disk drives in three RAID configurations: RAID 0 (striping), RAID 1 (mirroring), and RAID 0+1 (striping plus mirroring). You can also configure drives as “hot-spares.” For more information on all supported RAID configurations, see “About Disk Array Configurations and Concepts” on page 70.

The hot-plugfeature of the system’s internal disk drives allows the removal and installation of drives while the system is operational. This capability significantly reduces system down-time associated with disk drive replacement.
