Regionwide Scheduler
Regionwide Scheduler is available from SANcentral>Tools> Performance.
Regionwide Scheduler allows you to see total polls and productive polls per second for the region. The poller driver polls all of the channel boards on a storage server in a round robin scheme for I/O requests. A productive poll occurs when there is an I/O waiting to be taken from this board. An unproductive poll is when no I/O is available from the board. The left pane of the display indicates the percentage of productive polls to all polls per storage server. The right pane indicates the rate at which we are polling the boards per second per storage server.
