Technical Specifications
RAID controllers and cache memory	Dual independent controllers, each with environment management coprocessor for out-of-band remote management and monitoring 128MB of cache per controller (256MB total); support for up to 512MB per controller (1GB total) Cache Backup Battery Modules (sold separately) for over 72 hours of memory protection
RAID operation	Support for RAID levels 0, 1, 3, 5, 0+1,10, 30, 50 (10, 30, and 50 require host-based software RAID) Support for multiple RAID sets, multiple hosts, and LUN masking Background RAID set creation; automatic variable background rebuilding; global drive hot sparing (per RAID controller)
Fibre Channel storage-to-host connection	Dual 2Gb Fibre Channel ports (HSSDC2), 200MB/s throughput per channel with guaranteed bandwidth (400MB/s full duplex)² Host connectivity using 2Gb Apple Fibre Channel PCI Card (sold separately) or compatible third-party PCI card Support for point-to-point, loop, and fabric (switched) topologies Dual 10/100BASE-T Ethernet for remote management
Apple Fibre Channel PCI Card (sold separately)	64-bit, 66MHz card with dual SFP 2Gb Fibre Channel ports; compatible with 32-bit, 66MHz slots Two 2.9-meter Fibre Channel copper cables (SFP transceiver to HSSDC2); compatible with SFP fiber-optic cables and transceivers
Cooling	Redundant hot-swap cooling modules with self-regulating speeds and front-to-back cooling Environmental monitoring system for automatically maintaining optimal ambient temperature
Electrical requirements	Redundant load-sharing hot-swap power supplies (450W); universal input (90V to 264V AC), power factor corrected Maximum input current: 7.1A (90V to 132V) or 3.5A (180V to 264V) Power usage: 300W typical continuous power, 400W maximum continuous power Dual DB-9 serial ports for UPS systems Frequency: 47Hz to 63Hz, single phase
Environmental requirements	Operating temperature: 50° to 95° F (10° to 35° C) Storage temperature: –40° to 116° F (–40° to 47° C) Relative humidity: 5% to 95% noncondensing Maximum thermal output: 1365 BTUs per hour Maximum altitude: 10,000 feet FCC Class A approved
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.
