Refer to the exhibit. A customer has a three-site configuration, where Site-A is running
critical production applications, Site-B receives data from Site-A in SRDF/S mode and is
used exclusively for disaster recovery. Site-C is a new location designed to receive data
from Site-B using Cascaded SRDF. During the initial establish of data between Site-B and
Site-C, significant performance issues were encountered at Site-A. What action should be
taken to improve Site-A performance?

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 “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?

Refer to the exhibit. A company plans to deploy a two engine Symmetrix VMAX array in
their VMware vSphere environment. The ESXi hosts will be connected to the VMAX array
over a FC SAN. What is the recommended best practice when zoning an ESXi host with two
HBAs to the VMAX?

Refer to the exhibit. A customer has a Symmetrix VMAX storage array which had a capacity
add completed after one year of service. Performance for a specific host application with
large block I/O has not achieved expected levels of performance. The customer requests a
performance review and determination of the problem. You determine that FA processors
are running 52% busy, FA ports have an average of 30 MB/s and disks in the thin storage
pool are 28% utilized. Which cost effective solution should be suggested?

Refer to the exhibit. A customer has been performing VLUN Migrations between identical
pools and noticed the migration times have varied from minutes to hours. What would
explain the variations in the rate of migration?
