A single disk failure is the most common failure affecting storage systems today. To assess both resiliency and performance impacts during a disk failure scenarios, both cache and capacity disk failures were induced on the VxRail node. The resulting data resync was monitored with effect to write bandwidth. There was no video data loss during vSAN resync.
- Cache disk failure
- Disk Group is marked as failed and all components present on it will rebuild on another Disk Group.
- Capacity disk failure (Dedupe and Compression OFF)
- Disk marked as failed and all components present on it will rebuild on another disk.
