A potential customer requires 800 TB of usable capacity to store medical images for their network
of health clinics. The IT department has limited staff and currently manages four storage arrays
from other vendors. During a meeting with the Director of IT you learn that the company is
considering a solution from a competitor of EMC using two of the existing arrays and two new
arrays.
Which Isilon capabilities would show a better ROI for the customer?

A.
Isilon has 6%-12% less filesystem overhead than traditional clustered filesystem solutions.
With a single filesystem and virtual capacity for drive and node failures, Isilon utilization is typically
80% or higher.
Isilon utilization is typically 80% or higher due to use of a single filesystem and virtual capacity for
drive and node failures.

B.
With a single filesystem and virtual capacity for drive and node failures, Isilon utilization is
typically 80% or higher.
OneFS compression results in higher effective capacity within the cluster.
Traditional clustered filesystems require 4%-10% internal overhead compared to Isilon virtual
capacity.

C.
Forward Error Correction overhead is 7% lower than traditional RAID.
Isilon has 6%-12% less filesystem overhead than traditional clustered filesystem solutions.
According to an IDC study, Isilon improves IT productivity by nearly 50% compared to traditional
competitors.

D.
Isilon has 15%-20% less overhead than traditional clustered filesystems.
According to an IDC study, Isilon utilization is nearly 50% higher than traditional competitors.
Isilon QOS headroom and multiple node pools ensures consistent performance up to 80%
utilization.
