You are planning the storage requirements for an Exchange Server 2003. The server supports
750 users in a single Exchange Storage Group (ESG) with five databases. You need to calculate
the capacity required for the ESG. The customer has indicated that the average user mailbox will
be 125MB. The anticipated growth is expected to be 20%. What other factors need to be
considered to calculate the required capacity?

You are a designer for ABC.com. ABC.com, who has a mix of Windows and UNIX workstations,
decides to consolidate its storage onto a Symmetrix. ABC.com wants one copy of data to be made
for creating backups each night. ABC.com also wants a second copy to be made during the day,
which will serve as a standby for executing a fast recovery in the event of data corruption. Your
primary assessment of ABC.com environment illustrates that the read/write ratio of its application

is 1:2 during the day and 5:1 at night. The application appears to be extremely sensitive to disk
response times during the day. Which initial solution do you consider?

ABC.comcontacts EMC after an extended outage of a mission-critical application that results in a
large financial loss. The application is SAP/ Oracle running on Solaris servers connected through
a SAN to a CX700 array, and is currently running 8ms response times. What information is vital for
designing the best possible disaster recovery solution?

You are a designer for ABC.com. ABC.com’s applications are running on HP-UX servers attached
to a CX700. These applications currently use 50GB CLARiiON metaLUNs. The applications
require more disk space. You have already proposed expansion of the CLARiiON metaLUNs to
100GB. What other information is vital to the success of this solution?

ABC.com’s environment consists of 35 UNIX servers and 15 Windows servers, all of which have
either internal storage or a combination of internal and direct attached storage. These servers are
used for file sharing, home directories, and databases. Your objective is to carry out a complete
technical evaluation of the environment and have already documented information regarding all of
the servers. What should you also document?

ABC.com DBA has just inadvertently dropped a database table from its Oracle database. The
customer is looking for ways to recover it quickly. ABC.com runs an Oracle 9i application on a Sun
E4800 connected to a DMX2000. Which recovery options should you recommend?

Why is it important to properly calculate the number of ISLs when designing a fabric?

You are a designer for ABC.com. ABC.com’s environment consists of 65 servers, all of which have
either internal storage or direct attached storage. These servers are used for file sharing, home
directories, and custom applications. ABC.com reports that server response time is slow. Thus far,
you have concentrated your data assembly on the servers. What other aspect must you consider
that could be linked to the performance problem?

ABC.com is planning a second data center 20 miles (30km) away. The second site will be a
Disaster Recovery (DR) site and will also be a second tier data repository for less important data.
During the process of gathering information, you conclude that ABC.com can tolerate up to 30
minutes of data loss. a total of 1000 LUNs will need to be replicated to this site. You have. The
following values are observed after assembling Performance Manager data for a normal working
day Write response time: 5msRead response time: 14msWrite/s: 400Reads/s: 700
Which is a solution that you would recommend for this situation?

A client requested that you provide the number of physical disks required to support its Microsoft
exchange 2003 Storage Groups. The company has 12,500 users at 1.2 IOPS. AT peak activity, up
to 10,000 users could be logged on to exchange. What other information is required to accurately
calculate the number of required disk spindles to meet the user IOPS requirements?
