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. 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.
B. 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.
C. Isilon nodes have more drives per rack unit so fewer shelves are required.
Proactive hot sparing eliminates most drive rebuilds.
