General Description
The StorCase ® Technology InfoStation ® intelligent rack-mount expansion chassis is
designed to support the latest high-density, high-speed SCSI disk drive technologies for use
in network server, fault-tolerant and/or mission-critical applications. The InfoStation is
designed to support 3.5" form factor, low profile (1" high) SCSI Ultra320 devices.
The InfoStation 12-bay enclosure is designed to support twelve (12) low-profile single-
connect SCA SCSI devices in addition to one (1) 5.25" full-height or two (2) half-height SCSI
devices (such as a RAID or NAS canister-type controller, or a full-height tape drive). Each
chassis is constructed of rugged steel and lightweight aluminum, and is equipped with two
(2) hot-swappable power supply/blower modules, each containing one (1) load-sharing, load-
balancing 450W power supply and two (2) high-pressure, variable-speed blowers. A User
Interface module on the back of the chassis provides a visual indication of chassis
configurations and communication statuses, in addition to an RS-232 connection for system
environmental monitoring, configuration, and control.
The InfoStation SCSI backplane interface supports dual host interfaces, and is available with
integrated Ultra320 I/O repeaters (for daisy-chaining Ultra320 applications) or integrated
Ultra320 I/O modules.
The InfoStation also incorporates "Soft Start" circuitry which eliminates in-rush current to each
of the installed drives during spin-up, as well as avoid power arcing during drive insertion.
