cpqCrPartitionRAIDLevel

Logical Drive RAID Level.
              
This shows the RAID level of the logical drive.
To change the RAID level, run the CR3500 Array
Configuration Utility.
              
The following values are valid for the logical drive RAID
Level:
              
JBOD (2)
   Just a Bunch of Drives. Fault tolerance is not enabled. This
   logicl drive is made up of one device. Does not provide extended data
   redundancy, availability or protection, and does not use striping
   for performance enhancements.
   Good for applications requiring high device capacity. Requires one
   and only one device.
              
RAID0 (3)
   A logical drive using device striping and write-back caching.
   Data is spread across many devices, offering faster read/write
   performance than a single device. Does not provide extended data
   redundancy, availability or protection. Good for applications with
   large files needing high I/O performance. Requires a minimum of
   two devices.
              
RAID1 (4)
   A logical drive using device mirroring. Any time data is written to
   a device, a duplicate write is also made to a second device. Reading
   from multiple devices is usually faster than reading from a single
   device. Provides extended data redundancy, availability and
   protection. Good for read-intensive applications needing high
   availability. Requires a minimum of two devices.
              
RAID0PLUS1 (5)
   A logical drive where data is striped across devices and duplicated
   on an equivalent number of devies. Provides extended data
   redundancy, availability and protection. Good for applications
   requiring high availability, high performance and capacity.
   Requires an even number of devices, and a minimum of four devices.
              
RAID4 (6)
   A logical drive using device striping, with one device assigned for
   parity. Provides extended data redundancy, availability and
   protection. Good for applications such as graphics and imaging that
   call for writing huge, sequential blocks of data. Requires a minimum
   of three devices.
              
RAID5(7)
   A logical drive using device striping, with parity distributed across
   devices. Provides extended data redundancy, availability and
   protection. Good for transaction processing, applications requiring
   many, small I/O operations scattered randomly and widely across the
   devices. Requires a minimum of three devices.
