Performance Graphs
The
Performance Graphs
pane displays the performance charts in real time.
The performance graphs include the Latency, IOPS, and Bandwidth graphs.
Latency:
The Latency graph displays the average time it takes the array to process a read,
write, or read+write I/O request. The
blue
line represents the average read time, measured
in milliseconds; it takes the array to perform a read I/O operation. The
green
line represents
the average write time, measured in milliseconds; it takes the array to perform a write I/O
operation. The dotted
gray
line represents the average read+write time, also measured in
milliseconds; it takes the array to perform a read+write I/O operation.
IOPS:
The IOPS (Input/output Operations Per Second) graph displays host I/O requests
processed per second by the array. The counts request per second, regardless of how much
data is transferred in each. The
blue
line represents the number of read requests processed
per second. The
green
line represents the number of write requests processed per second.
The dotted
gray
line represents total read+write requests processed per second.
