Question 6

An experienced system administrator reports near maximum MPB utilization with VSP G400 arrays operating in a GAD pair. Each array is supporting 100K IOPS with a 50% read workload. The MPBs should be capable of supporting more than 200K IOPS with this profile according to the basic array sizing tools.
Which two statements are correct in this scenario? (Choose two.)

A. The internal array queue management scheme for GAD write operations causes MPB utilization to be doubled. B. Cache mirroring between the two G400 arrays generates an extra MPB load which is not recorded in Hitachi Tuning Manager. C. The duplex GAD writes are changing the overall read/write I/O profile and the extra parity operations are causing the high MPB utilization. D. Each G400 array is also processing 50K duplex write IOPS from the other G400.
