| Size and weight |
- 5.25 inches (13.3 cm) high by 17 inches (43.2 cm) wide by 18.4 inches (46.7 cm) deep
- Fits EIA-310-D–compliant, industry-standard 19-inch-wide four-post racks from 24 to 36 inches deep; deeper racks require third-party extender
- 60 to 110 pounds (27 to 45 kg), depending on configuration
|
- 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.
- Actual rates will vary depending on configuration and RAID level.
- Host operating system limitations apply.
- Automatic rebuild requires a designated hot spare; not available for RAID level 0.
- 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.
