Manage Level-2 Storage
PrimoCache implements a feature named level-2 cache. With this feature, PrimoCache is able to use solid-state drives or flash drives as cache for mechanical hard disks. Before using level-2 cache, a level-2 storage volume needs to be created first. It is a dedicated partition that is not recognized by operating systems, storing cache index and content. Each level-2 storage volume is able to provide cache storage for up to 16 cache tasks. Cache contents stored in level-2 storage are persistent and not deleted across computer restarts.
To create a level-2 storage volume, click on the icon button in the command toolbar. PrimoCache will pop up a dialog as below.
Click the Create Level-2 Storage button in this dialog to pop up the format dialog.
Select the partition that you want to be formatted to a level-2 storage volume. Usually it is a partition of solid-state drive or flash drive which is much faster than normal mechanical hard disks. If you haven't partitioned the SSD or flash drive yet, you need to create a partition first, by using Windows Disk Management or other partitioning tools.
Type the label to identify this new level-2 storage volume, if you don't like the default label name.
Now click the Format button to convert the selected partition to a level-2 storage volume. WARNING: The format process will cause all data in the selected partition to be lost and unrecoverable!
When successful, the new created level-2 storage volume will be listed in the management dialog.
You can view and manage existing level-2 storage volumes by clicking on the icon button in the command toolbar. In the popped-up dialog, select the level-2 storage volume to view the status of its partitions and free space. A partition of the level-2 storage volume refers to a continuous space area for one cache task. The column Cache indicates the index number of the cache task to which the partition belongs. PrimoCache automatically manages the partitions of level-2 storage volumes. If level-2 cache is specified when creating a cache task, PrimoCache allocates and creates a partition for the new cache task. When this cache task is stopped, PrimoCache deletes the partition accordingly.
There are two ways to change a level-2 storage volume back to a normal volume. One is using the PrimoCache level-2 storage management, and the other is using Windows Disk Management.
