You are designing a VNX storage solution for an Oracle database implementation. The VNX is populated with Flash, SAS and NL-SAS drives. The customer has asked you to recommend the optimal disk layout for the Oracle Automated Storage Manager instance disk group.
Which recommendation best conforms to EMC best practices?
A VMware v4 customer is considering consolidation of their environment to support their cloud IAAS (Infrastructure as a Service) initiative on VNX storage. They have a number of customers interested in deploying clustered application servers, across many varied application environments, onto this new infrastructure.
What advice would you give your customer to help them formulate their new environment and minimize their administrative overhead?

A customer is seeking insight about the data access profile on LUN 500, and has provided you the output shown in the exhibit. The Average Seek Distance (GB) parameter from Unisphere Analyzer shows a high value relative to the size of the disks that make up the RAID Group on which LUN 500 resides.
What can you determine about the data access profile of LUN 500?
A customer has implemented a VNX array that hosts multiple SQL database applications, but there are significant performance issues with some of the applications.

Click the calculator icon in the upper left-hand corner. A customer is building out a VDI environment of 1000 light users and 50 heavy users. They plan to use Boot from SAN for all VDI users. They are preparing a complete HA environment. If boot requires 6300 I/Os, with 5700 write I/Os and 20 seconds to complete. How many I/Os will occur during an HA failover in this environment?
