750GB Ultra ATA Drive Module
The Apple Drive Module (ADM) is a hot-pluggable Ultra ATA hard drive in a special drive carrier module designed for easy server and RAID upgradeability and maintenance. Apple Drive Modules are available in 250GB, 500GB, and 750GB sizes and operates at 7200 rpm. The 250GB and 500GB drives are equipped with 8MB of disk cache. The new 750GB drive uses perpendicular recording technology to achieve greater capacity while increasing performance and is equipped with 16MB disk cache. All drives are 24x7 enterprise-class rated and are ideal for applications needing capacity and great storage value with excellent performance.
Xserve RAID may be configured with up to fourteen drives, for up to 10.5 terabytes of storage. Unpopulated bays ship with a blank drive carrier which can be replaced with a drive module at any time — even if the server or RAID is running — so it’s easy to add storage capacity as your server and storage needs grow. Xserve RAID scales in performance and capacity with the addition of ADM hard drives.
Each ADM has two LED activity lights — one indicating drive activity and one indicating drive status. All Apple Drive Modules support SMART — Self Monitoring and Reporting Technology — allowing the hardware monitoring tools included with Xserve and Xserve RAID to monitor the status of each hard drive and report pre-failure warnings before problems occur.
RAID Management with Mac OS X Server and Xserve:
Management of Xserve RAID is provided through Apple RAID Admin, a powerful java-enabled management and monitoring tool. RAID admin allows you to securely setup and monitor Xserve RAID remotely across a local TCP/IP network or over the Internet.

RAID Set Expansion makes adding hard drives simple with no downtime. The enhanced utility also features testing and repair tools and an updated user interface.
RAID levels 0,1,3,5, and 0+1 are provided through dual hardware RAID controllers. Hardware RAID can be used in conjunction with Apple RAID software to achieve very high performance hybrid RAID levels 10, 30, and 50. Xserve RAID requires a minimum of four ADM hard drives.
Ultra ATA hard drives
Ultra ATA hard drives combine low cost with excellent performance. The drives have 8MB or 16MB of disk cache, operate at 7,200 revolutions per minute (rpm) and use a protocol that enables fast data transfer to and from the hard drive – 100 megabytes of data per second.
Apple Drive Module Ultra ATA Compatibility
These Ultra ATA drives are qualified for use with Xserve RAID only. For Xserve G5 or Intel-based products, use the Apple Drive Module with Serial ATA only.
System Requirements
Requires Mac OS X or Mac OS X Server v10.3.9 or later. Xserve RAID requires RAID Admin Update version 1.5.1 and firmware version 1.51b or later.
