PAM II cache

[ Edited ]

HI,

 

How do i find, which physical devices are consuming the PAM cache on the storage devices ?

 

Even after i use PAM still im facing read latency issue.

 

Thanks

Re: PAM II cache

Hi CP and welcome to the Communities!

PAM II (a.k.a. Flash Cache) will be beneficial for only certain types of workloads, namely when your hosts frequently read the same data again & again. If your read pattern is different, then PAM II will not help. Also be sure to 'warm up' the cache (fill with data) before doing any testing.

Here is a bunch of documents explaining all this in much greater detail:
