Procedure

Click [Setup Extreme Cache] in [Action].
•
Furthermore, when using EXC, note the following points:
-
If the PFM capacity in each CM for the ETERNUS DX500 S3/DX600 S3 does not match, the EXC memory
size that can be used for the relevant CM is reduced to the smallest capacity.
-
For the ETERNUS DX8700 S3/DX8900 S3, installing the same number of PFMs for each CM is not
required. By clicking the [Set] button, the PFM capacity that is installed in each CM is set as the
available EXC memory size.
-
When the performance monitoring process is started, the current PFM busy rate can be checked. Refer
to "Performance (PCIe Flash Module)" in "ETERNUS Web GUI User's Guide (Operation)" for details.
-
To enable or disable EXC for each volume, use ETERNUS CLI or ETERNUS SF Storage Cruiser.
-
EXCs can only be used when "Extreme Cache" is selected for "Cache Used" and EXC is enabled for the
volume.
•
Furthermore, when using EXCP, note the following points:
-
Enabling or disabling EXCP for each volume can be performed with ETERNUS Web GUI. Refer to
Modify Cache Parameters" (page 316)
for details.
-
EXCPs can only be used when "Extreme Cache Pool" is selected for "Cache Used" and EXCP is enabled
for the volume.
The target of the EXC setting is the ETERNUS DX500 S3/DX600 S3 and the ETERNUS DX8700 S3/DX8900 S3.
