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. 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.
• B. 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.
• C. 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.
• 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.

A healthcare services provider is implementing an X-Series cluster. Currently they have approximately 200 customers and they are growing at 30% per year. They have 200 TB of storage utilized. Health Insurance Portability and Accountability Act (HIPAA) regulations require they keep all patient data for seven (7) years. They would like to keep all genomic sequencing data stored with N+3 protection, not to exceed 75% utilization.
What is the minimum initial configuration you would recommend?

• A. 13 X200 nodes; 3 TB drives
• B. 6 X400 nodes; 4 TB drives
• C. 7 X400 nodes; 1 TB drives
• D. 13 X400 nodes; 1 TB drives
