Your customer has an existing Isilon cluster comprised of five NL-Series nodes. They have a new
project that will quadruple their current throughput requirements. Upon reviewing reports in
InsightIQ, you see that the aggregate external network throughput is peaking at 600MB/s. The
customer states that data is only active for the first 7 days, but they keep it indefinitely.
Which recommendation best supports their growth requirements?

A.
Add X-Series nodes to the cluster, and use SmartPools to migrate inactive data to the NLSeries nodes.

B.
Use the Isilon Sizing Tool to determine GNA requirements, and add NL-Series nodes with SSD
to the cluster.

C.
Add a VNX Unified array for the new project, and use rsync to migrate data to the Isilon cluster
for archiving.

D.
Add A-Series nodes to the cluster to boost combined network performance.
