RAIDXpert2 Feature Description Arrays (general information) RAIDXpert2 allows: • An array refers to data storage created by RAIDXpert2 from one or more disks. Although an array can be created from several disks, it is seen by the operating system as a single disk. • Creating arrays of different RAID levels using the same disks. • Creating different RAID level arrays on the same disk, to adapt each array to the I/O that it processes. • Creating an array from a mix of different type disks. For example, a RAID10 array can be created from a group of disks that contain two SATA II HDDs and two SATA SSDs or only on NVMe or group of SATA and NVMe disks. • Migrating an existing array to another RAID level, if the type of array being used is not the optimal type for the application. This function depends on the array capacity, redundancy level, RAIDXpert2 license level and capacity of the drive or free space available. Array Hiding An array can be hidden from the operating system so that neither the software nor users can see or access it. Array Recovery If a redundant array is accidentally deleted, it might be recovered by creating a new array with the same properties as the deleted array. (This can occur only if disk Write Access operations are not in-progress.) Background Array Initialization (BGI) The background initialization of a redundant array creates the redundant data that allows the array to survive a disk failure. Background initialization allows a redundant array to be used immediately. Data is not lost if a disk goes offline prior to completion of the BGI process. Cache Support for Arrays Various array-caching options are supported: No Cache, Read Ahead Cache, Write Back Cache, Read Ahead and Write Back Cache. |
