You have had several meetings with an existing EMC VMAX customer. They have agreed that they would like to review an initial Isilon Solution for unstructured data used by the Product Development Team. All production is managed through a Global Enterprise Resource Planning system based in Germany. They require 600TiB of usable capacity. The File System must be accessible from Windows and Linux High-End Workstations. The files are generally not accessed after 120 days, and they would like automated tiering.

Which questions about architectural integration will impact the solution design?

A.

• What Enterprise Resource Planning platform are they using in manufacturing?• What is their Recovery Point Objective?• What is their Archival Strategy?

B.

• How many data centers do they have?• Will their Network Infrastructure support implementing Isilon?• What Enterprise Resource Planning platform are they using in manufacturing?

C.

• How many clients will access the File System?• Will their VDI clients access the Isilon Cluster?• What is the DR plan for the ERP System?

D.

• What non-sizing-specific factors in the customer’s environment could impede integration of the Isilon solution?• What applications are they using?• What are your priorities among performance, scalability, or availability?
