8 Observing latencies and high I/O data
Various metrics central to the APLB behavior (such as array latencies and breakdown of data classified as
high, medium, and low I/O) are displayed using SAN HeadQuarters. These metrics are part of the I/O
subsection of each Group and can be readily observed for Groups, pool and the individual members within a
pool. Observing this information can be helpful in understanding the operation of the APLB. For more
information on SAN HQ, please consult the product documentation or Dell EMC document, Analyzing PS
Series Storage with SAN HeadQuarters.
