A potential customer requires 4 PB of usable capacity to store media files. The workloads are a combination of streaming video delivery and long term archive of video assets.
There is very little space available in the customer's datacenter, so physical density is very important. The customer is concerned about performance impact and potential data loss when using 3 TB or larger drives.
What Isilon capabilities can address the customer's concerns?

• A.Isilon does not perform rebuilds - data reprotection is typically 2x-3x faster than traditional RAID
  rebuilds.
  Data recovery is consistent, taking the same amount of time regardless of cluster size.
  Isilon 'short strokes' 4TB drives to reduce rebuild time.
• B.Isilon nodes have more drives per rack unit so fewer shelves are required.
  Proactive hot sparing eliminates most drive rebuilds.
  N+3 and N+4 Protection Levels exceed traditional RAID6 availability.
• C.Isilon does not perform rebuilds - data reprotection is typically 2x-3x faster than traditional RAID
  rebuilds.
  N+3 and N+4 Protection Levels exceed traditional RAID6 availability.
  Data redistribution runs faster with more nodes in the cluster.
• D.N+3 and N+4 Protection Levels exceed traditional RAID6 availability.
  Proactive hot sparing eliminates most drive rebuilds.
  Endurant Cache reduces the overhead for write operations.

Your customer is moving from a Restaurant/Bar business model to a Restaurant/Casino business model. You are helping architect the upgrade of a current 4-node X200 48 TB Isilon cluster, with 50% utilized for their video surveillance operations.
They want to upgrade from 15 FPS (NTSC) in H.264 codec, with a 15 days retention policy to 30 FPS (NTSC) in H.264 codec, with a 30 days retention policy.
How many nodes of the same type will you need to add in order to meet the required changes and not exceed
70% raw capacity?

• A.8 nodes
• B.16 nodes
• C.4 nodes
• D.12 nodes
