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?

Two weeks after configuring FAST-VP on a new VMAX array with EFD, FC and SATA tiers you
notice that FAST-VP is no longer moving data to the SATA tier which is 82% full. The active
FAST-VP policy lists 100% for the SATA tier. What is preventing more data moving to the SATA
tier?

A company plans to lay out their Oracle 11g OLTP database across four Symmetrix VMAX LUNs.
Which Oracle component can be co-located with the Control Files without impacting performance?

A customer implemented an Oracle application on a VMAX with a mix of Enterprise Flash Drives
(EFD) and FC 15K drives. EFD are configured in RAID 5 and FC 15K both in RAID 5 and RAID 1.
The application is random read intensive. The customer has decided to place a portion of the
database in each tier.
Which Oracle database files are suitable to be placed on EFD drives?

When setting up Symmetrix Access Control, what must be completed before all hosts have been
granted Access Control rights (via the Unknown Group)?

A customer needs to collect performance data from the HP-UX hosts in the environment. Which
collection utility is used?

For a 2 engine VMAX, what is the minimum number of Enterprise Flash Drives required to ensure
balanced performance across the backend excluding hot spares?

An existing 2-engine VMAX array has 192 x 450GB 15K Fibre Channel drives in a single Virtual
Provisioning pool. Two Linux database hosts are connected to the array and both are running
PowerPath.

Host oradb01 is connected to the E0 FA ports on each director and is meeting the customer
performance SLA. Host oradb02 is connected to the G0 FA ports on each director – and for the
past 3 days this host has been experiencing poor performance during peak activity in the
afternoons.
What steps do you take to identify likely bottlenecks?
