“Key Features
Massive storage capacity.
Fourteen drive bays hold up to 10.5TB of storage. Independent Ultra ATA drive channels eliminate interdrive dependencies to maximize bandwidth and availability.
High-speed throughput.
The dual independent 2Gb Fibre Channel host interface transfers terabytes of data at up to 1600MB/s fast enough for demanding HD video editing applications.
Superior data protection.
A high-availability architecture and dual independent RAID controllers support RAID levels 0, 1, 3, 5, and 0+1.
Maximum uptime.
Xserve RAID keeps running with redundant load-sharing power supplies and cooling modules. These field- replaceable modules enable service without tools or downtime.
Remote management and monitoring.
The included RAID Admin application makes it easy to set up, manage, and monitor Xserve RAID systems.
Server-class support products.
Resolve problems quickly with the AppleCare Premium Service and Support Plan and AppleCare Service Parts Kits.
Raid Levels
RAID 0: Striping.
Lays down data in stripes across an array of drives for exceptional I/O performance, but with no data protection.
RAID 1: Mirroring.
Writes identical copies of data on a pair of disks for total redundancy, but with limited performance and inefficient use of drives.
RAID 3: Striping with parity.
Stripes data across two or more drives and stores parity data on a dedicated drive, providing data redundancy and performance that’s faster than that of a single drive.
RAID 5: Striping with distributed parity.
Distributes data and parity information across an array for high throughput, good redundancy, and efficient use of drives.
RAID 0+1: Striping over mirroring.
Stripes data across pairs of mirrored drives for a mix of performance and redundancy.
RAID 10, 30, and 50: Striping over RAID 1, 3, and 5.
Uses hardware RAID to create two or more sets in RAID level 1, 3, or 5, and software RAID to stripe across the sets. This creates a single data volume with the best balance of performance and data protection.
