QUESTION NO: 1
A customer has two sites, with a VNX system at each site. The local site has four application LUNs of 256 GB each. They are replicated to the remote site with MirrorView/S. The linkbetween the sites has an effective bandwidth of 100 MB/s. The application generates 800 random IOPS of 8 kB with a 3:1 R/W ratio on each of the LUNs. The link fails for 15 minutes.
How much data is copied to the secondary LUNs as part of the resynchronization process?

You implement FAST VP on an existing EMC VNX. The Extreme Performance pool holds 5% of usable storage, the Performance pool holds 20%, and the Capacity pool holds 75%. The Tiering Policy is set to Auto.
The attached hosts run several applications. Some applications access data frequently, while others are write-once read-never. Twenty minutes after tiering is started, the customer reports there is no performance improvement. How should you respond?

A DBA wants to create a replicated, recoverable copy of an Oracle 11g database environment that will reside on a number of EMC VNX target drives.
The DBA performs the following:
-Puts the required tablespaces in hot backup mode
-Issues a checkpoint to the database
-Synchronizes and fractures the Oracle device pairs
-Ends hot backup mode
-Brings the replicated copy online
What action must the DBA take to enable the copy to start up successfully?

QUESTION NO: 5
A customer is using VNX Replicator to replicate data from a single file system to a remote
location. They are planning to replicate more file systems, but monitoring tools are showing bursts of data on the link instead of a smooth and constant flow of data. They also notice that latency on the link is higher than expected.
What would you advise them to do to make more efficient use of the link?
