質問 # 22
A potential customer has a requirement for 4 PB of usable capacity to store media files. Their data center has limited physical space, so efficient use of that space is important. However, the customer is concerned about using 3 TB or larger drives because of rebuild times.
How does an Isilon cluster address this customer's concern?
Response:
- A. OneFS protects data rather than rebuilding drivesSplitting drives into failure domains reduces risk
- B. Proactive hot sparing eliminates most drive rebuildsEndurant Cache reduces the overhead during drive rebuild operations
- C. Drive recovery takes the same amount of time regardless of drive sizeShort-stroking 4 TB drives to reduce drive seek and access time
- D. Nodes have more drives per rack unitProactive hot sparing eliminates most drive rebuilds

質問 # 37
We have been engaged by a research hospital to help upgrade their Isilon installation. They currently have 12 previous generation Isilon nodes with 200TB of capacity and run on a 1Gbps network. They currently have 6 IIlumina Hi-Seq Sequencers and an HPC cluster to process data.
They would like to expand Isilon to 2PB of active data and 1PB of archive dat a. They use a third party data and metadata management service (IRODs) to stage data for analysis. The Isilon cluster is mainly used for analysis work with the HPC cluster. The customer has a limited budget.

Response:
- A. 14 X-Series nodes with no SSD drives and 96GB of RAM
- B. 17 X-Series nodes with SSD drives and 48GB of RAM
