A company has a VMware vSphere ESXi 5.0 host. They have been noticing performance issues
when they receive bursts of heavy I/O workloads after a relatively low period of CPU utilization.
Which measure could be taken in the VM configuration to alleviate this issue?

An SRDF/Star customer wants to move their production from the current workload site to one of
the target sites. Which operational step is necessary before executing the symstar halt command?

You have been requested to design a Symmetrix VMAX FAST-VP storage solution. When
considering skew, what is a primary performance metric that should be used during the design
process?

A customer is implementing a new ESXi cluster and will be provisioning 50TB of storage from
Symmetrix Pool Storage. The size of the LUNS being presented is 150GB. Based on EMC Best
Practices, on how many storage ports should LUNS be presented?

A Symmetrix VMAX storage array is designed for performance with the following configuration:
4 engines
128 GB cache per engine
1152 FC 15K drives
Workloads will be segregated
What will be the limiting factor for performance?

A customer has several Solaris 10 hosts that they will connect via FC to an EMC VMAX. The
hosts are all dual-pathed with PowerPath installed. Each host will be assigned 5 volumes on the
VMAX. Each volume will be an 8-member metavolume.
What is the actual throttle depth for each Solaris host?

A large customer has a formal Capacity and Performance Management (CPM) department. This
customer’s business users describe the environment as both good and challenged. They are
acutely aware when there are performance short-falls or insufficient storage resources available.

How would you categorize this Performance Management style?

Click on the calculator icon in the upper left corner. A customer is implementing an Exchange
2010 environment for 500 users on an EMC Symmetrix VMAX and has the following requirements.
– 1 GB mailbox quota per user.
– Each user sends and receives approximately 125 messages per day.
– The average message size is 65 KB.
– Deleted items will be retained for 14 days.
What is the minimum capacity recommended for each mailbox?

A customer has a new four engine Symmetrix VMAX storage array installed at their site. The array
will be the target for a consolidation of three Symmetrix DMX storage arrays. The customer has
concerns about required performance for a specific application that currently uses logical volumes
from two of the source arrays. All applications that use this storage will have different peak usage
times during the day.

How can the customer configure the new VMAX cache to guarantee the best level of service to the
specific application?

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?
