Click on the calculator icon in the upper left corner. A new storage request is submitted for
the production instance of an new application from development. The request is for 3 x
200GB LUNs on a recently purchased VMAX array. While discussing the request with the
application team they mention that performance of their test environment has been poor
during load testing on an existing DMX-4 array. You check Performance Manager statistics
for the DMX-4 and discover that they are using 3 x 100GB LUNs for testing and they are
sometimes reaching Device Write Pending. What will best avoid the Write Pending issue in
production?

What allows VMkernel to reduce memory duplication in the virtual machine’s memory?

You are planning a migration for 20 VMware ESXi 5.0 servers from a DMX-4 to a new EMC
VMAX array. Each server uses VMFS volumes and hosts more than 50 VMs. The customer
reports their environment workload tends to be low outside of normal business hours but
their service level agreement only permits one 4-hour offline window per quarter. Which tool
do you recommend be used to migrate the ESXi servers to the VMAX?

A company is investigating memory issues with a VMware vSphere implementation. How
would the company determine if there are memory issues at the host level when monitoring
through a vSphere vCenter Server?

Which database workload is suitable for EFD configuration?

You are designing a Symmetrix VMAX Virtual Provisioning solution for a VMware vSphere
environment. Storage allocation must be guaranteed for some mission critical virtual
machines. What format should you recommend when creating virtual disks for these
mission critical virtual machines?

You are designing a boot from SAN solution for VMware ESXi servers connected to a
Symmetrix VMAX storage array. What is a consideration?

A customer has a Symmetrix VMAX array shared between several different business
groups. Each of the hosts has Solutions Enabler installed to support TimeFinder operations.
There is a requirement that each business group can only manage its assigned LUNs.
Which security technology would enable that requirement?

A new data warehouse will be hosted on an existing 4-engine VMAX array. The database
server has 4 HBAs connected at 4Gb/s. Due to limited SAN switch ports only port 0 on each
VMAX FA is connected – also at 4Gb/s. The workload is expected to require at least
2300MB/s of reads at 128KB I/O size and must maintain performance in case of any major
component failure in the host, switch or array. Assume that the existing workload on the
VMAX does not exceed 100MB/s per port and assume that the ports can sustain up to
300MB/s without exceeding 70% utilization. What is the minimum number of FA ports
needed to spread the workload evenly across all 4 VMAX engines and meet the above
performance requirements?

A customer has a Symmetrix VMAX attached to 12 UNIX servers through a SAN fabric.
They would like to prevent unauthorized access at the port level. Which Symmetrix security
feature would satisfy that requirement?
