Disk Enclosure Features

The Model 4214 enclosure supports up to fourteen, 1-inch high, 3.5-inch form factor hard disk drives. This enclosure is available in either a rack mountable version (4214R) or in a tower (4214T). A rack (cabinet) mounted enclosure requires a RETMA 3U vertical opening (5.25-inches) where a “U” is 1.75-inches.

The enclosure provides several features, including:

Hot-pluggable drives, environmental monitoring unit (EMU), fans, and power supplies are replaceable without halting SCSI bus data transfers.

Pluggable I/O module and SCSI bus cables require quiescing the bus (that is, stopping all data transfers), but do not require removing power before replacing.

Depending upon the host controller, the I/O module is capable of supporting Wide-Ultra SCSI (LVD) or Wide-Ultra SCSI (SE) bus operations.

Depending upon the host-interface controller, an EMU may support the automatic monitoring of specific enclosure and drive functions.

The enclosure has guides that ensure the drives, EMU, I/O module, and power supplies (the enclosure elements) align and properly mate with the backplane connectors. A guide post on the fan ensures that the fan properly mates with the power supply. The elements and the metal enclosure provide electromagnetic interference (EMI) suppression and control airflow within the enclosure.
