A single disk in a vSAN disk group suffers from an unrecoverable hardware failure. This causes vSAN to set the health status for all disks in the group to Permanent disk loss, indicating disk failure.
Assuming all other disks have not suffered from a hardware failure, why would vSAN mark all disks in the group as failed?
The vSAN disk management service has failed.
The affected vSphere host is offline.
The key management server is offline.
Deduplication and compression are enabled on the vSAN cluster.
Correct answer: A
Question 2
A storage administrator discovers vSAN is rebalancing components across a cluster randomly and faces degraded performance on the applications.
What should be done to avoid these issues?
Size at least two disk groups on each node
Maintain a minimum of 10 percent unused capacity
Keep total storage consumption <70 percent
Ensure there is sufficient queue depth on the I/O Controller
