Question 990
On a service ticket for Harborworks, the team observes: A file server has two equal 2 TB disks and needs redundancy against one disk failure. The supporting record states that a proposed RAID 0 stripe provides speed but no copy of data on a second drive. The desired outcome is to choose RAID 1 when simple mirroring is the requirement. The customer requires a verified fix rather than a guess based on one symptom. How should the solution first be tested on an approved spare or pilot system?
- Create a small lab array of two mirrored pairs striped together
- Simulate a single disk failure in an isolated RAID 1 test array
- Benchmark random reads on approved test HDD and SATA SSD devices
- Model two drive failures on a disposable RAID 6 lab array
