B) Upgrade RAM on the nodes
C) Add Solid State Drives (SSDs) to the nodes
D) Add an A-Series Performance Accelerator node

2. You set up a meeting to gather information on a new project with the IT manager and plan to use a workflow profile assessment (WPA) to document the requirements.
Why is it recommended to talk to as many stakeholders as possible?

A) Helps downstream personnel, such as implementation and delivery, to have a clearer understanding of the requirements.
B) Using workflow profile enables sales to take this information to EMC consulting for review to validate the configuration.
C) Using the WPA tool will give you the best "big picture" to see things such as block size, de-dupe, file size and volumes.
D) Completing this document gives sales a list of who the stakeholders are at customer site.

3. You are working with a healthcare company that is interested in replacing all the backend storage for their PACS system.In general, how should the solution be presented to the customer?

They have a variety of workloads on each cluster and are in the process of determining which workloads belong on which cluster.

The database vendor has suggested limiting latency to 5ms or less to eliminate these timeouts.
How do you advise the customer?

A) Suggest the customer consider leveraging SSDs in the new nodes they purchase and GNA to boost the performance of each cluster.
B) Consider migrating data from Isilon to one of their SAN platforms or proposing a new solution to handle the performance requirements of SQL.
C) Recommend they increase the amount of DRAM in the cluster or consider an Accelerator node in order to increase the amount of cache in their cluster.
D) Merge the S-Series nodes and X-Series nodes into one cluster, upgrade the 1GbE to 10GbE, and leverage SmartPools to allow for the cluster to determine where data should reside.
