The correct answer is A. Latency is less than 1 ms for all large I/O sizes, deduplication with compression, and scales. Storage capacity and performance scale linearly, such that two X-Bricks supply twice the IOPS, four X-Bricks supply four times the IOPS, six X-Bricks supply six times the IOPS and eight X- Bricks supply eight times the IOPS of the single X-Brick configuration. However, the…

Question

A customer is considering XtremIO storage for their current Virtual Desktop Infrastructure (VDI) deployment. The customer wants information on the benefits of an XtremIO solution. What are the benefits of an XtremIO solution for this environment?

Options

  • ALatency is less than 1 ms for all large I/O sizes, deduplication with compression, and scales
  • BLatency is less than 1 ms for large I/O sizes, deduplication and compression, and no reduction in
  • CLatency is less than 1 ms for small I/O sizes, scales linearly, and slightly higher cost/IOP/GB than
  • DLatency is less than 1 ms for small I/O sizes, deduplication and compression, and scales linearly

Explanation

Storage capacity and performance scale linearly, such that two X-Bricks supply twice the IOPS, four X-Bricks supply four times the IOPS, six X-Bricks supply six times the IOPS and eight X- Bricks supply eight times the IOPS of the single X-Brick configuration. However, the latency remains consistently low (less than 1ms) as the system scales out. The sub-millisecond latency is validated by actual test results, and is determined according to the worst-case scenario.
