A customer wants to implement virtual provisioning on a new VMAX array and is concerned about efficient use of available storage and application performance.
The VMAX environment will have file system, database and document repository hosts. The customer reports the system hosts append data to the file system, the database hosts use auto-extend and the document repository hosts have low performance and growth requirements.
How should you recommend the host storage be provisioned on the VMAX array?
A. File system storage on traditionally provisioned volumes; database and document repository storage on thin volumes.
B. File system, database and document repository storage on thin volumes.
C. File system and database storage on thin volumes; document repository storage on traditionally provisioned volumes.
D. File system, database and document repository storage on traditionally provisioned volumes.

Q81. - (Topic 2)
A proposed SRDF/S solution was modeled with BCSD using host-based data.
.
The BCSD model assumed two engine VMAX arrays with SRDF Fibre ports.

What should you recommend?
A. Use three engine VMAX arrays
B. Provide more bandwidth
C. Turn off software compression on the remote adapters
D. Change the application layout
Answer: D
