The “Primary Components” diagram on page 1-7illustrates the 6500 disk array primary components described below.

The standard 6500 enclosure consists of a front cover and an enclosure cabinet, built in a desktop configuration. (An optional rack-mounting kit is available.)

An air filter is located between the disk drives and the front of the enclosure. It must be periodically cleaned to ensure proper air flow.

The controller board is designed with a multiple local bus architecture. A master microprocessor commands the board's main processor bus and manages its operations, including command optimization and processing, failed drive processing, and high-level drive operations. The master processor communicates with each drive via an ATA controller circuit. Communications between the master processor and each drive occur on separate but identical drive channels.

Power Supply

The operator interface includes a two-line 32-character LCD display and six control switches.

9 ATA disk drives (8 data, one parity).

Two fans cool the array. A sensor mounted on the array’s controller board monitors the temperature inside the enclosure, and triggers an audio alarm if the temperature rises above the normal operating range. If excessive heat is detected (critical over-temperature), the array will shut down the drives.

The array’s power supply is switch-selectable for 115 or 230 VAC operation. A male connector attaches to the power source.

Caution Do not use female power connector.
