Hit Ratio
Description
The frontend I/Os for the sequential
write requests for all the RAID
Groups managed by the ACP pair.
The total frontend I/Os made on an
external volume.
The total random frontend I/Os rate
on this external volume during the
entire collection interval.
The total random frontend reads
rate on this external volume during
the entire collection interval.
Out of the total random frontend
reads rate on this external volume,
the number of random reads
available in the cache.
The total random frontend writes
rate on this external volume during
the entire collection interval.
The total sequential frontend I/Os
rate on this external volume over
an entire collection interval.
The total sequential frontend I/Os
rate on this external volume for a
given range of time.
The number of sequential frontend
reads serviced from the cache in
terms of the I/Os rate on this
external volume.
The total sequential frontend write
rate for this external volume over a
given time interval.
It is the ratio of the total frontend
I/Os occurring on a ThP pool
versus the total backend tracks
associated with a ThP pool.
Each External RAID
Group value is the sum
of all the LDEVs in all
the Ext-RAID Groups in
the array.
