What is the purpose of the Usermapper on VNX?

What is a characteristic of secmap?

Which VNX virtual device can be deployed independently of pre-existing customer Ethernet
configurations?

Which statement describes the Reserved LUN Pool?

You are trying to create a virtual network device in Unisphere. There are four physical network
connection devices on the Data Mover, but only two appear on the Unisphere device creation
page.
Why?

An environment contains five LUNs of 65 GB each, and five LUNs of 35 GB each. Each of the
LUNs will have a SnapView Snapshot created on it.
What is a recommended configuration of the Reserved LUN Pool?

An environment contains five LUNs of 160 GB each, and five LUNs of 140 GB each. Each of the
LUNs will have a SnapView Snapshot created on it.
What is the recommended configuration of the Reserved LUN Pool?

A customer has an environment consisting of 25 classic LUNs of 100 GB each that hold data from
a custom application, and 15 thick LUNs of 50 GB each that are used for a database application.
Free disk space on the system amounts to 800 GB.
The customer runs a scan of the classic LUNs each night to check for data corruption. The
application must be shut down in order to run the scan. Scans are taking too long to run, and
production is affected. The customer asks for a solution to the problem.
