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?
