You Have Been Working with a Customer to Size a New

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.
