Question
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?
Options
- AIsilon does not perform rebuilds - data reprotection is typically 2x-3x faster than traditional RAID
- BN+3 and N+4 Protection Levels exceed traditional RAID6 availability.
- CIsilon does not perform rebuilds - data reprotection is typically 2x-3x faster than traditional RAID
- DIsilon nodes have more drives per rack unit so fewer shelves are required.
