A server providing streaming video to clients is configured with storage from an EMC Symmetrix VMAX array. The data on this server is static and does not change. The file system for the videos is on a 600 GB striped metavolume made up from 8 x 75 GB standard RAID 5 devices.
The storage administrator is baselining the performance of the system using Performance Manager. The administrator notices that the "seq reads per sec" metric is much lower than expected for a heavy sequential read application.
What is the most likely reason for this situation?
A. Prefetch algorithm skews the sequential read statistics for heavy sequential workloads
B. There is not enough cache in the array to handle a heavy sequential read workload
C. Prefetch is disabled for this metavolume
D. Metavolume should have been concatenated
