PFA reports
The PFA monitoring program enables SM2 to record monitored data on the use of various
caches. These caches can be served by the products DAB and PCA.
DAB supports the caches in main memory, expanded storage and global storage. PCA
supports the caches in the 3419, 3421, 3860 and SYMMETRIX controllers.

If PFA serves the cache via DAB and the DAB monitoring program is activated, DAB
monitored data will be supplied in addition to PFA monitored data and output in the DAB
reports. If PFA serves the caches of 3419/21 controllers via PCA and the PCA monitoring
program is activated, PCA monitored data will be supplied and output in the PCA reports.
When serving the caches of SYMMETRIX controllers, you need only activate the PFA
monitoring program in order to output monitored data in the SYMMETRIX reports.

When serving the caches of SYMMETRIX controllers, you need only activate the PFA

Unlike other SM2 monitoring programs, the information recorded by PCA is not host-
specific, rather refers globally to a controller. This must be taken into account particularly
when interpreting the data.

when interpreting the data.
The PFA CACHE report provides a non-product-specific overview of the use of all caches.
The PFA CONTROLLER report supplies controller-specific monitored data on a PFA cache
served by PCA and whose devices can be assigned to different controllers.
