Introduction
Foreground initialization
Foreground initialization will zero-out all data on the array. The array is not accessible
by the operating system until initialization is complete.
Background initialization
Background initialization allows the array to be used immediately. For RAID1 arrays,
initialization will results in data being duplicated identically to the mirror pair.
Note: An un-initialized RAID1 array can still provide redundancy in case of a disk
failure.
Online Capacity Expansion (OCE)
This feature allows disks to be added to existing RAID arrays, in order to increase the
array's capacity, without fear of data loss. Any number of disks can be added to an
array, at any time. Data can be accessed and utilized even while being redistributed.
Online RAID Level Migration
This term describes the ability to change one type of array (RAID level), into a
different type of array. Data is still accessible during the migration process.
Legacy disk
Disks attached to the RocketRAID 1720 that contain valid partition tables will be
identified as legacy disks. A legacy disk attached to the RocketRAID 1720 can be
accessed by the operating system, but cannot be used to create RAID arrays. A
legacy disk must be initialized before assigning it to an array.
