Verifying the capacity saving effect with Storage Navigator or Command Control Interface
You can verify the capacity saving effect for each pool.
The following table shows items indicating of the saving effect.

Capacity |
Used |
raidcom get pool -key fmd |
(Not Available) |
Pool used capacity. As for CCI, a free capacity (ACT_AV(MB)) is displayed. |
|
Used (%) |
U(%) |
Pool used capacity rate | ||
|
Data Volumes Used Capacity |
(None) |
raidcom get pool -key total_saving |
DATAVOL_USED(BLK) |
Total used capacity of DP-VOLs |
|
Saving Effect (Capacity saving effected by both of the capacity saving function and accelerated compression function.) |
Saving Ratio |
SES(%) |
Ratio of the pool used capacity (#1) against the total used capacity of DP-VOLs (#3). | |
|
Saving |
SE_SAVING(BLK) |
Saved capacity (= the total used capacity of DP-VOLs (#3) - the pool used capacity (#1)) | ||
|
Software Saving (Saving effected by the capacity saving function) |
Saving Ratio |
raidcom get pool -key software_saving |
PLS(%) |
The saved ratio with the capacity saving function. |
|
Compression Ratio |
(Not Available) |
The saved ratio with the compression function. As for CCI, a data capacity before compression (PRE_CMP_USED(BLK)) is displayed. | ||
|
Deduplication Ratio |
The deduplication ratio with the deduplication function. As for CCI, a data capacity before deduplication (PRE_DDP_USED(BLK)) is displayed. | |||
|
Saving |
PL_SAVING(BLK) |
The saved capacity with the capacity saving function. (=Compression (#10) + Deduplication (#11) + Reclaim (#12) - System Data (#13)) | ||
|
Compression |
CMP(BLK) |
The saved capacity with the compression function. | ||
|
Deduplication |
DDP(BLK) |
Deduplicated capacity | ||
|
Reclaim |
RECLAIM(BLK) |
The reclaimed capacity. | ||
|
System Data |
SYSTEM(BLK) |
The system data capacity (= Meta data capacity + Garbage data capacity). | ||
|
Used (Pre Processed Data) |
PL_PRE_USED(BLK) |
The data capacity before performing of the capacity saving function. | ||
|
FMD Saving (Saving effected by the accelerated compression function) |
Compression Ratio |
raidcom get pool -key fmd |
(Not Available) |
The saved ratio with the accelerated compression function. As for CCI, a zero pages reclaimed data capacity before performing of the accelerated compression function deduplication (FMD_LOG_USED(BLK)) is displayed. |
|
Saving |
The saved capacity with the accelerated compression function. | |||

|
FMD Capacity |
Used |
FMD_ACT_USED(BLK) |
The used capacity after compressed with FMD. | |
|
Logical FMD Capacity |
FMD_PLV_USED(BLK) |
The used capacity before compressed with FMD. | ||
