A Potential Customer Requires 4 PB of Usable Capacity to Store

question 326

Multiple Choice

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. N+3 and N+4 Protection Levels exceed traditional RAID6 availability. Data redistribution runs faster with more nodes in the cluster.
• B) Proactive hot sparing eliminates most drive rebuilds. Endurant Cache reduces the overhead for write operations.
• C) Data recovery is consistent, taking the same amount of time regardless of cluster size. Isilon 'short strokes' 4TB drives to reduce rebuild time.
• D) Isilon nodes have more drives per rack unit so fewer shelves are required.

Egg Cell

The female gamete or reproductive cell involved in sexual reproduction, which when fertilized by a sperm, develops into a new organism.

Sperm Cell

A cell produced by the male reproductive system for the purpose of fertilization, carrying half of the genetic information required to form a new organism.
