Click on the calculator icon in the upper left corner. Refer to the exhibit. 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 “N:\”. You
have decided on RAID-5 protected 15,000 RPM drives for the new SQL database and
RAID-1 for the transaction log. 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 87 GB worth
of data. Following EMC best practices, which discount can be taken from the overall write
IOPS, when calculating for the database writes?
