A Potential Customer Requires 800 TB of Usable Capacity to Store

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) 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. 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.
