Power 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.
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.

Interoperability
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.
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 1-15
for more information.

Fibre 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.
