RAIDXpert2 Feature
Description
Multiple RAID Levels per
Disk
Support for multiple array levels per disk allows the administrator to
create arrays of different RAID levels using the same disks.
Native Command Queuing
(NCQ)
Native Command Queuing is a command protocol of disks that are
supported by RAIDXpert2. NCQ enables individual disks to internally
optimize the order in which Read and Write commands are executed.
RAIDXpert2 permits a queue depth of up to 32 read/write commands per
disk.
Online Capacity Expansion
(OCE)
OCE is a process that allows the user to add storage capacity to an
existing array, without taking the system offline. OCE enables the user to
increase the total storage capacity of an array by integrating unused
storage into the array.
Data can be accessed while the disks are added and while data on the
array is being redistributed.
Note: This feature is not available with all license levels. See Table 5.
Online RAID Level Migration
(ORLM)
With online RAID level migration, users can easily move an array from
one RAID level to another. While the migration is taking place, data is
accessible and protected to the lowest protection of either the source
RAID level or the destination RAID level.
Note: This feature is not available with all license levels. See Table 5.
RAID Level Support
RAIDXpert2 supports RAID levels 0, 1, 5, 10, Volume, and RAIDABLE.
Note: RAID5, and RAIDABLE are not supported by all license levels. See
Table 5.
Note: The ability to create RAID10 or RAIDABLE arrays may not be
available on your system.
Self-Monitoring Analysis and
Reporting Technology
(SMART)
SMART is a hard-disk-drive (HDD) capability which allows reporting of
reliability information. If a drive anticipates there is a high likelihood of
future failure it triggers a SMART error condition. RAIDXpert2 presents
this error condition so the drive can be replaced before the predicted
failure occurs.
