What is the best method to achieve the desired objectives?
A customer owns a CX340 SAN for their Microsoft application environment. In the course of a SnapView implementation, you discover that the Microsoft file systems are misaligned on the production LUNs. The file systems need to be aligned prior to implementing SnapView for these hosts. Host downtime needs to be kept to a minimum.

Based on the information you have gathered, which solution should you recommend?
A manufacturing customer has decided to consolidate storage onto a CLARiiON. The customer uses a mix of Windows and UNIX workstations during the product design process. One of the customer’s goals is to use pointintime copies of data to make backups easier. In addition, they would like to have the ability to use the pointintime copies to perform a fast recovery in the event of accidental file deletion. The cost of the solution is important.
Your survey of the environment shows that the read/write ratio of the application is 3:1. The application appears to be insensitive to disk response times.
Based on the information you have gathered, which solution should you recommend?
Where should you look for an indication of the source of the problem?
In an interview with your customer’s backup administrator, you learn that the Exchange backups are failing frequently. You believe physical database corruption (1018 errors) is the root cause.

Which feature can be incorporated in the DMX4 to reduce the disk count and still satisfy the application’
A customer’s OLTP environment resides on a DMX2000 with 30 146 GB 15k drives to satisfy the IOPS requirement of the application. The customer is about to refresh the storage environment and deploy a DMX4.
Which feature can be incorporated in the DMX4 to reduce the disk count and still satisfy the application’s IOPS requirement?
What is the most likely design attribute that is responsible for this behavior?
A customer has a DMX3 with an application workload that is experiencing long response times with write operations during monthend batch processing. The customer has observed that other applications on the same DMX are experiencing long read response times during this same time period.
What is the most likely design attribute that is responsible for this behavior?
From a performance point of view, what is the minimum number of 2 Gb array ports that can handle both the work
A customer has four applications (A, B, C, and D) that run daily as follows:
Application A has its consistent peak workload of 25 K IOPS with an average 8 KB blocksize for 3 hours from 10 A.M.
Application B has its consistent peak workload of 25 K IOPS with an average 4 KB blocksize for 4 hours from Noon
Application C has its consistent peak workload of 45 K IOPS with an average 4 KB blocksize for 3 hours from 1 P.M.
Application D has its consistent peak workload of 15 K IOPS with an average 4 KB blocksize for 4 hours from 11 A.M.
From a performance point of view, what is the minimum number of 2 Gb array ports that can handle both the workload and 25% growth into a single array?
What is the likely reason for this performance issue?
During a proof of concept, a customer who is using a CLARiiON array with four Windows servers notices I/O performance problems on a specific server. Looking at Navisphere Analyzer data for the LUNs in question and comparing the statistics with the System Monitor (PerfMon) I/O counters for the same Windows physical disks, the I/O statistics in Navisphere Analyzer are significantly higher than the System Monitor shows.

Which EMC Avamar design feature addresses the customer’s question?
A customer has a large number of remote clients that they would like to back up to a centralized server at their data center. Many of these remote clients do not have the required bandwidth to perform traditional backups. The customer is looking at various deduplicationbased backup applications and has asked you to explain what makes EMC Avamar a better fit for their environment.

What are some security issues that you should discuss with the customer?
A customer is deploying EMC ControlCenter as part of their SRM solution. The customer has indicated that they will provide their own hardware and OS platform.

Which solution presents the best option for Exchange recoverability?
You have a prospective customer with two SQL servers, one Exchange server, and two file servers.
They have requested a bid for a Fibre Channel SAN but due to budget constraints, your sales representative wants to show them an iSCSI alternative.
Capacity requirements total approximately 4 TB. Exchange recoverability is a chief concern for the prospect. Which solution presents the best option for Exchange recoverability?
