You are designing the Symmetrix VMAX architecture for a DAS-to-SAN SQL Server migration.
Currently all user databases reside on a single locally attached disk enclosure, mounted to “M:\”.
You have decided on RAID-1 protected 15,000 RPM drives for the new SQL environment.
Last week, you configured Perfmon to record the current IOPS load of the databases during the 8-hour business day, Monday thru Friday as shown in the exhibit. During an average business day,
the transaction log processes 43 GB worth of data.
Following EMC best practices, which discount can be taken from the overall write IOPS, when
calculating for the database writes?

A.
392

B.
597
