Do any one know, what is data follow if a cache memory DIMM failed in USPV?
Does it turn on write through mode ?
If Single Cache DIMM failed on a cluster it wont turn on write through mode
My USPV has 02 cache DIMMs failed. -> Does it turn on write through mode ?
No it wont write through mode. You can even check the IOPS on the cache
After cache dimm failed, could you tell me the system status like delayed host response time delay or reduced IOPS?
Find manual about SOM685.
You can find you want.
For default setting of USPV, cache module fault does not occur write-through mode.
When maintenance procedure for replacement cache module, write-through mode occur.
For SOM685 ON, the situation change.
It depends about SOM685, Cache PCB number and Microcode Version.
