You have 1000 users for an application that reads and writes files averaging between one and four
MB in size. Each user requires 24 MB of RAM. You want to add another 1000 users for this
application, and in preparation for them, you run the isi statistics command. You discover that the
average CPU utilization is 20%; aggregate throughput averages 700 MB/s and the disk QueueD
average is 1.5. Your cluster currently has five X200 (12 GB RAM, 1 TB drive) nodes, uses N+2:1
protection and 1 GigE networking.
What should you do to accommodate the next 1000 users?

A.
Add five additional X200 (12 GB, 1 TB drive) nodes

B.
Upgrade each X200 node to a total of 24 GB of RAM.

C.
Upgrade two of the 1 GigE NICs to 10 GigE on each node.

D.
Add five A100 (24 GB RAM) accelerator nodes.
