A customer configured an EMC VNX to serve home directories to users. Users report intermittent
timeouts accessing the home directories. While troubleshooting, you observe you can
successfully connect to the file share, and can ping the VNX interfaces. What is the most likely
cause of this performance issue?

A customer asks you to design an EMC VNX for an Oracle database composed of 300 GB RAID 1
and 600 GB RAID 5 (4+1) drives. Which configuration provides maximum usable capacity
balanced with reasonable performance?

A healthcare company uses MirrorView replication between VNX located at their two data centers.
They use the Write Intent Log (WIL) feature on both VNX. There was an outage at the production
data center and production workload was transferred to the DR data center. When then
production workload was failed back to the production data center, the customer found all
MirrorView LUNs completed a full re-synchronization. What caused this situation?

A vSphere ESXi v5.0 administrator receives an alert that a VM (virtual machine) has been paused.

A client has a storage requirement for an object database. The application is expected to
generate random I/O requests. The I/O profile is:

– 70% random reads
– 30% random writes
– Total host I/O per second is 20,000
– Required usable capacity is 35 TB
The client is concerned about cost, so RAID 5 (8+1) data protection will be used.
What is the minimum number of 300 GB 15K SAS drives needed to meet the client’s performance
and storage requirements, including hot spares drives?
