Technology Overview

Xserve RAID

Convenient replacement modules

Problem resolution is fast with the

AppleCare Service Parts Kits for Xserve

RAID (sold separately). Each kit has an

Apple Drive Module, power supply

module, cooling module, and RAID

controller module.

RAID controller modules. Two independent storage processor units manage RAID

functions, data transfers, and failure protection for each set of seven drives. The

environment management coprocessor in each controller simplies conguration

and management of RAID sets.

Serial ports. Standard DB-9 serial ports allow connection to UPS units for protection

from brownout or over-voltage conditions.

Ethernet ports. The 10/100BASE-T Ethernet interfaces allow you to manage, monitor,

and diagnose Xserve RAID systems over TCP/IP.

Fibre Channel ports. Each RAID processor connects to the host system via a 2Gb

Fibre Channel interface with throughput of up to 200MB/s per port.

Throughput

is assured, which means bandwidth remains constant, even as more devices are

added in a fabric conguration. Industry-standard SFP connectors support both

optical and copper infrastructures.

Optional batteries. Cache Backup Battery Modules can provide more than 72 hours

of backup power to protect the integrity of data in the RAID controller cache during

a power outage.

Power supply modules. Either of the redundant, load-sharing power supplies can

power Xserve RAID should the other one fail. A failed power supply can be replaced

in seconds without tools and without shutting down the system.

Cooling modules. Redundant, hot-swappable cooling modules provide automatic

front-to-rear cooling for rack environments.
