RAID levels are numbered from 0 through 6; a higher RAID level does not necessarily indicate a higher level of performance or fault tolerance. The RAID controllers support RAID levels that have proven to be the most useful for RAID applications: RAID 0, 1, 10, 3, 5, 50, and 6. You can use Non-RAID - HP StorageWorks MSA2012fc | HP StorageWorks 2000 Modular Smart Array Reference G - Page 250
than that of a RAID 0 virtual disk, because write operations involve calculating and writing new parity data as well as writing the new user data. 250 HP StorageWorks 2000 Family Modular Smart Array reference guide • August 2008 - HP StorageWorks MSA2012fc | HP StorageWorks 2000 Modular Smart Array Reference G - Page 251
RAID 50 RAID 50 virtual disks are made up of two or more RAID 5 virtual disks, across which data is striped. RAID 50 virtual disks contain redundant information in the form of parity data, which is calculated block-by-block for all user data. As in a RAID 5 virtual disk, the parity information is - HP StorageWorks MSA2012fc | HP StorageWorks 2000 Modular Smart Array Reference G - Page 252
