cpqFcaAccelReadCache
Module: CPQFCA-MIB
OID (symbolic): CPQFCA-MIB::cpqFcaAccelReadCache
OID (numeric): 1.3.6.1.4.1.232.16.2.2.2.1.11
Node type: OBJECT-TYPE
Type: INTEGER

Description: Read Cache Memory.
This shows the amount of memory allocated for the read cache in megabytes.
What is cpqFcaAccelReadCache?
This integer reports, in megabytes, how much of the array accelerator's cache memory is currently allocated for read caching. An administrator checks it to confirm the controller's read-ahead cache is sized as expected, since a low or zero value on a controller that should have a large accelerator board could point to a misconfiguration or a failed board. For example, seeing 128 on a controller expected to report 256 would prompt the admin to reseat or reconfigure the array accelerator.
