Your customer would like to add a NAS head (NS700G) to their existing CX700 CLARiiON array. The utilization of all of the disks in the array is roughly 50%. Navisphere Analyzer reports that the read throughput is typically equal to the cache hits/sec. No forced flushing is occurring. The workload on the hosts that are using the array is large, sequential read I/O.
You are asked what the performance implications would be of adding the NAS device to the exiting SAN.

What is your response?

A.
Since forced flushing is not occurring, and the current applications are sequential in nature, the NAS head should not degrade performance.

B.
The NS700G will not degrade the performance of the existing SAN since a typical NAS workload consists of 80% sequential I/O, and 20% random I/O.

C.
In general, if the utilization of the disks is less than 85%, the addition of the NAS head should not degrade performance.

D.
A typical NAS workload could severely disrupt a sequential workload. You would recommend only if the NAS and SAN workloads could be placed on separate spindles.
