— Write Through: The controller sends a data transfer completion signal to the host when the virtual drive has
received all of the data and has completed the write transaction to the drive.
— Write Back: The controller sends a data transfer completion signal to the host when the controller cache has
received all of the data in a drive write transaction. Data is written to the virtual drive in accordance with
policies set up by the controller. These policies include the amount of dirty and clean cache lines, the number
of cache lines available, and the elapsed time from the last cache flush.
— Force Write Back.

Figure 70 View Drive Group Properties Window
A drive group is a logical grouping of drives attached to a RAID controller on which one or more virtual drives can be
created. Each virtual drive in the drive group must be configured with the same RAID level. This figure shows
information for one drive group.
In this window, the Capacity Allocation entry for each drive group displays associated virtual drives for the drive
group. The window also indicates whether the drive group is secured and protected. To see how much free space is
available in the drive group, highlight a Capacity Allocation field and press Enter. The information appears in a
popup window.
