A VMware 5 customer is planning to upgrade their networking environment to 10 Gb Ethernet. They would also like to use real time vMotion to ensure balanced application load distribution throughout their environment. They are also currently running their VMware environment on 64bit, dual core processors.

What advice would you give to your customer to assist them with the upgrade of their environment?

A. Upgrade their servers to quad core CPUs or greater and ensure all servers have access to the datastores.

B. Configure NIC teaming on their servers and ensure that all VMs on each ESXi server are configured for FT.

C. Ensure all servers have multiple paths to all arrays to support VM file movement and all VMs are configured for HA.

D. Ensure that all vMotion sessions are configured for core 0 (zero) affinity and enable Direct Path I/O.

A customer's database resides on a RAID 5 Pool with SAS drives.

Which best practice should be followed to optimize Reserved LUN Pool disk performance?

B. Use equal size thin LUNs from the same Pool as the database

C. Use only SAS disks on dedicated RAID Groups

D. Use only NL-SAS II drives on dedicated RAID Groups

You are currently investigating a SQL performance issue on a VNX array. You narrow down the RAID group where the log file resides. You find that the disk response time is 12 ms.
