Xserve (Late 2006) Take Apart — Hard Drive Module
11
Apple Drive Module
Xserve (Late 2006) includes three hard drive bays on the front panel. Hard drives come as
modules, known as Apple drive modules (ADMs), attached to carriers; they are removed from or
installed in the Xserve as a unit. ADMs have been available from Apple in various capacities for
all Xserve and Xserve RAID models, and in multiple interface types. Xserve G4 and Xserve RAID
use parallel ATA (PATA) ADMs, and Xserve G5 uses serial ATA (SATA) ADMs. Xserve (Late 2006) can
use SATA ADMs, and ADMs with a new, third interface type known as serial attached SCSI (SAS).
It is important to understand ADM forward compatibility and backward compatibility with older
Xserve models, since some combinations of ADM and Xserve or RAID work properly while other
combinations do not. The following table summarizes this compatibility.

(Late 2006)
NO† NO† NO†† OK OK
* PATA connector is physically different from SATA connector so this ADM will not fit completely
into slot.
† PATA connector is physically different from SAS connector so this ADM will not fit completely
into slot.
†† Will fit completely into slot but ADM will not work or be recognized by the Xserve. Installing
the SAS ADM should not damage the drive, however.
Note: Blank drive carriers, which may fill some of the hard drive bays, follow the same take-apart
procedure as hard drives. If you are replacing a blank carrier with a drive module, instruct the
Xserve’s administrator to keep the blank for possible future use. Blank carriers must be installed in
all empty bays to maintain proper airflow through the Xserve.
