You have been working with a customer to size a new Isilon cluster for their environment. You
recently determined that a cluster with three X400 nodes with 1TB drives and 48 GB RAM would
be a perfect starting point for their workflow, but will have extra capacity. The customer just
informed you that they have decided to also use the cluster for a small home directory
environment and implement SmartQuotas.
Which configuration changes should you consider?

A.
Increase the memory and add SSDs to the configuration.

B.
Add an additional X400-Series node to the configuration.

C.
Add three NL-Series nodes with 1 TB drives with 48GB RAM, and use SmartPools.

D.
Add three S-Series nodes with 300GB drives with 48GB RAM, and use SmartPools.
