The total IO/s (reads and
writes) on that port over
a given duration. This
port in turn connects to
the host group through
which the I/Os reach the
port.
Total IO/s – Frontend
The total IO is obtained by
summing up all the IO of
all the LDEVS for the given
host group.
The total IO of all the
LDEVs created in a spe-
cified RAID group for the
given Host group over the
entire data collection inter-
val.
Total IO – Frontend
The total IO writes is ob-
tained by summing up IO
writes of all the LDEVS for
the given host group.
The total IO writes of all
the LDEVs created in a
specified RAID group for
the given Host group over
the entire data collection
interval.
Total IO Writes– Frontend
The total IO reads is ob-
tained by summing up IO
reads of all the LDEVS for
the given host group.
The total IO reads of all
the LDEVs created in a
specified RAID group for
the given Host group over
the entire data collection
interval.
Total IO Reads– Frontend
The total IO Miss is ob-
tained by summing up IO
miss of all the LDEVS for
the given host group.
The total IO miss of all the
LDEVs created in a spe-
cified RAID group for the
given Host group over the
entire data collection inter-
val.
Total IO Miss– Frontend
Each RAID group value is
the sum of the LDEVs in the
RAID group.
The sum total of the fron-
tend I/Os on all the
LDEVs created in a RAID
group.
RAID Group Total IO –

The sum total of the fron-
tend random I/Os on all
the LDEVs created in a
RAID group.

dom IO – Frontend
The frontend random read
I/Os on all the LDEVs
created in a RAID group.
RAID Group Random
Reads – Frontend
Out of the sum total of
frontend random read
I/Os on all the LDEVs
created in a given RAID
group, the number of
random reads available
in the cache.
