Data Volume Protection

About data volume protection information on the Configure tab → Storage feature

Traditional Array Parity Linux MDRAID allows for up to two disk failures per array without loss of data. Rebuild times are proportional to disk size. Linux GridRAID or Declustered Parity facilitates faster rebuilds after disk failure. GridRAID also supports up to two (2) disk failures per array without loss of data. GridRAID enables significantly faster reconstruction of data redundancy after a disk failure, followed by rebalancing the layout to include a new disk.

Disk IO Integrity Guard Message

If the disks and IO controllers on a system support the ANSI T10 Protection Information (T10-PI) standard, then the system was installed with this option enabled. The Disk IO Integrity Guard message will indicate that the standard is supported. Using this standard protects data integrity during IO operations by adding extra information to verify each block when it is written to disk or read from disk. There is no loss of usable disk capacity, and there is negligible performance impact.
