A customer is in the design phase of their SQL server implementation. They request your guidance concerning the number of disk drives needed to properly configure the database for performance. The current utilization of the database is shown below:

80% reads and 20% writes

10K SAS disks

RAID 5

1150 IOPS

What is the minimum number of disk spindles required to service the random I/O requests during usage of the SQL Server database?

A. 12

B. 14

C. 18

D. 20

An application generates 500 random 8 KiB IOPS with a R/W ratio of 3:1. An asynchronous mirror is started on the application LUN. The update cycle is configured to be 30 minutes, and updates take 15 minutes to complete. Assume that the data rate is constant.

What is the minimum space that should be configured for the Reserved LUN Pool on the secondary VNX?

A. 879 MiB

B. 7,032 MiB

C. 14,064 MiB

D. 16,250 MiB

A customer is migrating an application to a virtualized environment. After the implementation is completed they realize that performance is below their expectations.

You are tasked to investigate and recommend an economical solution. Using VMware Tools and Analyzer on the VNX, you conclude that their application servers are experiencing CPU over- utilization and storage connection congestion.

What should be your first recommendation?

A. Ensure that VMware Paravirtual SCSI virtual adapter is configured

B. Move application to faster drives

C. Increase memory

D. Enable compression on the LUN

You are conducting an analysis of a Celerra system to migrate the data to a new VNX Unified storage system. You want to measure the current connections for the CIFS/NFS protocol. Which "server_stats" statistic type would you use to get the desired information?

A. Fact

B. Counter

C. Element

D. Correlated Set

Refer to the exhibit.

Which process is illustrated in the exhibit?

A. FAST Cache warmup

B. FAST VP slice relocation

C. FAST VP policy change

D. FAST Cache writeback

Refer to the exhibit.

You are proposing a storage solution using VNX to support a Microsoft Exchange 2010 virtual implementation on VMware ESXi. You have worked with the customer to understand the Exchange requirements, which are described in the exhibit. Based on availability, performance, and Exchange mailbox size requirements, you are recommending RAID 5 with 7.2K rpm NL/SAS drives.

Following EMC best practices, what is the minimum number of spindles that would be required for this environment?

A. 16

B. 26

C. 34

D. 48

In designing a disk layout with multiple disk types, which metric should be used for data locality?

A. Seek Distance

B. Queue Length

C. Response Time

D. Utilization

Click the calculator icon in the upper left-hand corner. A clone source LUN is 2 TB in size. It performs 450 random 16 kB IOPs with a 2:1 R/W ratio. As part of ongoing testing, the clone is fractured for five minutes and then resynchronized. The testing is performed every hour.

How much data (to the nearest GB) is read from the source LUN as part of the resynchronization process?

A. 6 GB

B. 22 GB

C. 44 GB

D. 88 GB

A Customer is planning to build a VDI environment on a VNX array. The customer is working to determine what type of VM replicas would be acceptable in their environment. It needs to have best performance. What could be recommended?

A. Full clones

B. Snap clones

C. Flash clones

D. Link clones

A customer is supporting 800 Exchange users on a VNX5700. The users are divided among four Exchange storage groups using a total of eight LUNs each for data and logs and two LUNs for a cluster quorum disk and MSDTC. The company purchased a VNX5300 for its remote site. The company is using MirrorView/A with consistency groups to ensure consistent point-in-time recovery. The Exchange LUNs have been added to the consistency group, but the administrator is having trouble adding the quorum and DTC LUNs.

What should the administrator do?

A. Create a second consistency group for the quorum and DTC LUNs

B. Evenly distribute all LUNs across both SPs before adding them to the consistency group

C. Create ten consistency groups (one for each LUN) and ensure that the update frequency is the same for all groups

D. Fracture all mirrors before adding them to the consistency group
