CAUTION:
SSD cache function is not support when the system memory is under 8GB
per controller.

SSD Cache Pool Architecture
A SSD cache pool is grouped to provide capacity for SSD cache usage of a dedicated
storage pool. The maximum SSD cache pool quantity per system (either dual controller or
single controller) is 4. The following is the storage architecture of SSD cache pool.
Figure 10-2
Storage Architecture of SSD Cache Pool
Take an example of SSD read cache; one or more SSDs with NRAID+ (which is described in
the next section) are grouped into the “SSD Cache Pool 1” and assigned to the “Pool 1” for
use. The maximum SSD quantity in an SSD cache pool is 8. When the SSD read cache is
performing, the capacity of the SSD cache can be increased by adding an SSD or decreased
by removing an SSD.
Another example of SSD read-write cache; two SSDs with NRAID 1+ (which is also described
in the next section) are grouped into an SSD group. One or more SSD groups combine to the
“SSD Cache Pool 2” and assigned to the “Pool 2” for use. When the SSD read-write cache is
performing, the capacity of the SSD cache can be increased only by adding an SSD group
with two SSDs at a time. The SSD read-write cache pool can be set SSDs as dedicated hot
spares. The maximum dedicated spare SSD quantity in an SSD cache pool is 4.
