A customer with a virtualized environment has asked you to architect a new VNX storage solution utilizing their many NFS datastores. They are also deploying a new Cisco Unified Computing System as their compute base. However, they believe that virtualizing their critical servers may cause network performance concerns because these servers have a very high transaction rate with a CPU bound application.

How would you respond to your customer's concerns?

A. Deploy their environment as architected, and enable DirectPath I/O for their servers.

B. Deploy their environment as architected, with CNA configured for Jumbo frame support, end- to-end.

C. Their environment will not be compromised by virtualization; it can be deployed as architected.

D. Their environment will not be compromised by virtualization, but it requires pNFS on the ESXi and VNX systems.

Your customer is operating a payment processing application on a Windows Server cluster with the back- end Oracle databases running on Oracle Enterprise Linux (OEL). Both the application and database environments have been presented storage from the customer's VNX solution.

Your customer reports less than optimal performance for their online payment processing application. While utilizing IOSTAT, utlbstat and utlestat, a high load on the buffer cache and I/O system performance issues are found on the database servers.

What is the most likely problem?

A. Redo logs are too small

B. High Amounts of Recursive (SYS) SQL

C. Long Full Table Scans

D. Shortage of rollback segments

A customer is considering purchasing a new VNX with MCx. Performance of the application is the top priority. What would you recommend the customer consider before proceeding with this design?

A. overhead associated with tracking the metadata of a Thin LUN and detriment to performance as the LUN grows.

B. The benefits of FAST Cache with regard to improving LUN performance

C. FAST VP and the improved granularity of the data slices

D. Classic LUN

A customer recently added a large number of new users to their VNX for Block storage system. They now notice that the system is slow. You have been asked to fix this problem. Their configuration uses only Classic LUNs. They have some

unused Flash drives. Analysis shows that several LUNs have skew rates of 90% or higher.

Which technology would you implement to solve their performance problem?

A. FAST Cache

B. FAST VP

C. Flash RG

D. Pool LUNs

The customer wants to display File System statistics data in Unisphere. What is the default polling interval (Minutes) for Statistics Logging?

A. 10

B. 5

C. 15 D. 20
