  • 60 to 110 pounds (27 to 45 kg), depending on configuration
  1. For hard drive capacity measurements, 1GB = 1 billion bytes and 1TB = 1 trillion bytes; actual formatted capacity less. Usable capacity depends on drive configuration and RAID level.
  2. Actual rates will vary depending on configuration and RAID level.
  3. Host operating system limitations apply.
  4. Automatic rebuild requires a designated hot spare; not available for RAID level 0.
  5. A separate AppleCare Premium Service and Support Plan must be purchased for each Xserve RAID system to be covered. To qualify, your Xserve RAID system must be within its one-year hardware warranty. Coverage ends three years after date of Xserve RAID purchase. Actual onsite response time and availability of onsite service depend on location; see www.apple.com/support/products/premium for details. Local telephone fees may apply; telephone numbers may vary and are subject to change.
