Click on the calculator icon in the upper left corner. A new storage request is submitted for
the production instance of an new application from development. The request is for 3 x
200GB LUNs on a recently purchased VMAX array. While discussing the request with the
application team they mention that performance of their test environment has been poor
during load testing on an existing DMX-4 array. You check Performance Manager statistics
for the DMX-4 and discover that they are using 3 x 100GB LUNs for testing and they are
sometimes reaching Device Write Pending. What will best avoid the Write Pending issue in
production?

A.
Allocate 3 x 4-way striped meta devices using 50GB hypers

B.
Allocate 3 x 4-way striped meta devices using 200GB hypers

C.
Allocate 3 x 200GB devices and reduce the System Write Pending limit to 70%

D.
Allocate 3 x 200GB devices and increase the Device Write Pending limit to 10%
