The total IO writes is obtained
by summing up IO writes of The total IO writes of all the
LDEVs created in a specified Total IO Writes – Frontend
all the LDEVS for the given
host group. RAID group for the given
Host group over the entire
data collection interval.
The total IO reads is obtained
by summing up IO reads of The total IO reads of all the
LDEVs created in a specified Total IO Reads – Frontend
all the LDEVS for the given
host group. RAID group for the given
Host group over the entire
data collection interval.
The total IO Miss is obtained
by summing up IO miss of all The total IO miss of all the
LDEVs created in a specified Total IO Miss – Frontend
the LDEVS for the given host
group. RAID group for the given
Host group over the entire
data collection interval.
Each RAID group value is the
sum of the LDEVs in the RAID
group. The sum total of the frontend
I/Os on all the LDEVs
created in a RAID group. RAID Group Total IO –

The frontend sequential read
I/Os on all the LDEVs
created in a RAID group. RAID Group Sequential
Reads – Frontend
The number of sequential
frontend read I/Os serviced RAID Group Sequential
Reads Cache Hits – Frontend
from the cache in terms of
