You review a Unisphere Analyzer report from a customer’s EMC VNX. You observe that disk read
activity is higher than can be accounted for from host reads and normal pre-fetch activity.
What is the likely cause?

A.
Writes on the array are reasonably sequential, but there is not enough data in cache to fill each
stripe.

B.
Individual writes are being requested and sequenced until the entire stripe is cached and parity
is calculated before being written.

C.
Disk crossings and stripe crossings are normal events where large I/O is involved.

D.
The Unisphere Analyzer report was run against the wrong storage processor.
