EMC Symmetrix Array Performance

Table: EMC Symmetrix Array Performance

Metric

Description

Host IOs

The number of host I/O operations per second by all Symmetrix volumes. This includes random and sequential reads, and writes to the volume.

Host MBs

The total requests per second (from all front-end directors) that were satisfied from cache.

Host MBs Read

The number of MB per second read by all Symmetrix volumes.

Host MBs Written

The number of MB per second written by all Symmetrix volumes.

BE Reqs

The number of a read or write data transfers between cache and the back-end director.

WP Count

The number of system cache slots that are write-pending.

Percent Cache WP

The % of system cache that is write-pending.

Avg Fall Thru Time

The average time it takes a cache slot in LRU0 to be freed up. This value represents the average time from the first use of the contents to its reuse by another address.
