Hot Pluggable SATA or SAS Drives

Xserve (Late 2006) includes three hard drive bays at the front of the Xserve. All bays support hot-pluggable Apple Serial ATA (SATA) or Serial Attached SCSI (SAS) drive modules.

In the Xserve (Late 2006), drive bays are numbered 1-3,beginning with the far left bay. The bay in which a drive is installed determines its master/slave position, thereby eliminating the need for jumpers or special drive configuration. The drive installed in bay 1 is the master drive and should have the operating system installed on it.

Xserve Drive

You can replace or install hard drives while the Xserve is running; you do not need to shut down or open the Xserve first, but you may need to dismount the drive from the Xserve OS beforehand. A status light on the front of each drive indicates when it is safe to remove the drive without losing data. For more information, see "Hard Drive Module" in the Take Apart chapter.

FB-DIMM Memory

The Xserve (Late 2006) has 8 memory slots. The systems come with at least 1 gigabyte (GB) of memory on two fully-buffered dual inline memory modules (FB-DIMMs). To improve performance and capacity, you can install additional DIMMs for a total of up to 32 GB of memory. The 8 memory slots are labeled DIMM 1 through DIMM 8.

You can use the following memory in the Xserve (Late 2006):

  • 667 MHz DDR2 ECC FB-DIMMs
  • 512 MB, 1 GB, 2 GB, or 4 GB in matching pairs (optimal, 4 or 8 identical DIMMs)
  • 36 devices per DIMM, maximum
  • Error-correcting code (ECC)

Important: Apple recommends that you use Apple-approved FB-DIMMS. Other FB-DIMMs might degrade the performance of the Xserve. DIMMs from older Xserve systems are not compatible with this Xserve.

Note: Before you purchase DIMMs other than those recommended by Apple, make sure that the memory manufacturer conforms to the Joint Electronic Device Engineering Council (JEDEC) specification. Make sure that the DIMMs support the correct timing modes and that the Serial Presence Detect (SPD) feature has been implemented in accordance with the JEDEC specification. To check DIMM compatibility, see the Macintosh Products Guide on Apple's website at www. You can purchase Apple-approved memory online from the Apple Store at
