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, what is the minimum number of spindles that must be allocated for optimal transaction log performance?

A customer engaged technical support for a performance issue with their application. The exhibit shows IOPS for the four FA processors utilized to connect the HPUX host to the storage. The FA processors are dedicated to the application. All logical volumes, ports and storage are part of a single masking view. What should the customer change to enhance performance of the host?

A customer has a VMAX 1 Engine with 128 GB of cache. The disks are configured in RAID 1 and SRDF is not implemented. The applications on the VMAX perform heavy writes with a ratio of 20/80 (Reads/Writes). Due to continuous rate of writes, the VMAX reaches the Device Write Pending Limit.
What is the most cost effective way to address the problem?
