1.2.5Power and Fan Modules

Note – The SATA arrays can only be ordered in an AC configuration. However, DC power supplies can be ordered in an x-option kit, and the SATA arrays can be reconfigured using the DC power supplies. For details, refer to the SANnet II Family FRU Installation Guide.

Each array contains two redundant power and fan modules. Each module contains a 420-watt power supply and two radial 52-cubic-feet-per-minute (CFM) fans. Power module autoranging capabilities range from 90 volts alternating current (VAC) to 264 VAC for AC power supplies, and from –36 volts direct current (VDC) to –72 VDC for DC power supplies.

A single power and fan module can sustain an array.

1.3Interoperability

The array is designed for heterogeneous operation and supports multiple host operating systems. Refer to the SANnet II 200 FC, SATA, and SATA SE Array Release Notes to see the current list of supported hosts, operating systems, and application software.

The array does not require any host-based software for configuration, management, and monitoring, which can be handled through the built-in firmware application. The console window can be accessed via the DB9 communications (COM) port using the Solaris tip command or equivalent means for other operating systems, or with the Ethernet port using the telnet command. Management and monitoring software is available and shipped with the array. See “Additional Software Tools” on page 1-15for more information.

1.4Fibre Channel Technology Overview

As a device protocol capable of high data transfer rates, Fibre Channel simplifies data bus sharing and supports not only greater speed than SCSI, but also more devices on the same bus. Fibre Channel can be used over both copper wire and optical cable. It can be used for concurrent communications among multiple workstations, servers, storage systems, and other peripherals using SCSI and IP protocols. When a Fibre Channel hub or fabric switch is employed, it provides flexible topologies for interconnections.
