ABC.com has approached EMC for a meeting to discuss storage consolidation. ABC.com’s
datacenter currently consists of several hundred Windows and UNIX servers. ABC.com’s
Windows environment consists of application servers, web servers, and file servers. ABC.com’s
UNIX systems are running Oracle ERM systems. Furthermore, ABC.com has two mainframes
running their inventory control system, as well as a mixture of DAS and SAN islands (Brocade
Silkworm 1GB switches) along with some old HDS connected to its mainframe that total
approximately 150TB. ABC.com is growing quickly and is searching for methods to bring
expenses under control. High availability has become a priority because of recent outages that
were caused by single points of failure in its storage infrastructure. Which components would be
most appropriate when designing the SAN?

ABC.com has An HP-UX 9000/800 host that currently uses multi-pathed storage provisioned from
a Symmetrix 8830. All LUNs are presented to the host application utilizing Veritas Volume
Manager. ABC.com is replacing the storage array with a DMX1000, and this will require a data
migration effort. The host is running numerous 24×7 applications and has to be online during the
migration. You are considered the following two approaches:host-based mirror/split of the Veritas
volumesarray-based SRDF What drawback does using host-based volume mirroring have for the
migration?

What is a benefit of port channeling in MDS-series switches/directors?

ABC.com will install CX-series CLARiiONs to store its development code, and plans to utilize
Clones for protection against data corruption. That unauthorized users might access the
CLARiiONs and make changes to the configuration, is a concern for ABC.com. Yet, they insist on
having only one storage administrator. How do you implement CLARiiON security at this site?

A software engineering firm has decided to implement shared networked storage to facilitate
project development. There are approximately 40 servers in the company with 25% Solaris and
75% Windows. It does not want to add any additional servers for storage. The company
anticipates no more than 30% growth over the next three years. The storage utilized for the

network file systems must be maintained on the most cost effective and easiest to manage
solution. However, storage must also be tracked so that required storage for project can be
charged back to the development teams. The network file system will also be used for non-project
related storage from other departments such as Human Resources (HR) and Accounting. Space
allocation for non-project files must be monitored and reports generated for management. Which
solution set best satisfies the customer’s criteria? All solutions will include Professional Services
Implementation.

You are a designer for ABC.com. ABC.com’s IT Manager asks you to calculate storage
performance on a Symmetrix DX800 that is thought to be performing poorly. During the analysis,
you find hotspots on backend devices related to the Oracle database layout. You then devise a
solution that includes reallocating storage volume copies on the backend. What technical
information will reinforce your solution with the IT Manager?

You are the head of the design team for ABC.com. Your team has completed the gathering and
analysis phases of the design. The solution you propose has the following advantages:

A reduction of capacity-related outages by 80% An increase in application uptime by 10% A solid
base for a multi-platform operational management system Which ABC.com role is affected by
these benefits the most?

ABC.com has two HBAs in its server. Of the following, which PowerPath algorithm would probably
cause IOPS to be equally distributed across HBAs?

You are a designer for ABC.com. ABC.com calls you into a meeting to discuss its Exchange
environment. ABC.com currently has a DMX1000 running its OLTP applications, which are
running on AIX hosts using 6 of DMX’s 10TB for storage. This leaves 4TB of available space
across DMX. ABC.com’s Exchange environment (10,000 seats) is currently running on six HP
servers with direct attached storage. The Exchange servers are using approximately 3TB of
space. The Exchange administrator reveals that he receives calls to restore emails that have been
deleted every day. ABC.com has had several disk hardware problems and would like to progress
to faster and more reliable storage. Which of the following would be a suitable preliminary design
for ABC.com’s Exchange environment?

ABC.com has a DMX 1000 at its production site. ABC.comis planning to purchase another DMX
1000 for its Disaster Recovery (DR) site 20 miles from the production site. While information
gathering, you conclude that its RPO is 30 minutes. ABC.com has a total of 30 LUNs that will need
to be replicated to the remote site via a T3 link. ABC.com’s application is sensitive to response
times. After using Performance Analyzer to collect data for a normal working day, you note the
following Analyzer values:
Write response time: 5msRead response time: 14msAverage I/O size: 4KBWrite/s: 400Reads/s:
700
Of the following, which solution would you recommend?
