Drive Array Benefits
Using drive arrays with the Smart Array 3200 Controller has several important benefits:
■Data Protection
■Performance Enhancement
■Capacity Changes
■Data Reliability
Data Protection
The Smart Array 3200 Controller provides several options to produce data redundancy for a more reliable system including distributing data, fault- tolerance methods, assigning online spares, and rebuilding data.
Fault-Tolerance (RAID) Options
During configuration, you will make RAID (Redundant Arrays of Independent Disks) level choices. RAID is the term used for an array technology that provides data redundancy to increase system reliability and performance.
RAID levels range from
■RAID 5 - distributed data guarding
■RAID 4 - data guarding
■RAID 1 - drive mirroring (also RAID 0+1, or RAID 10)
■RAID 0 - no fault tolerance (data striping only)
