5.8 Understanding How Failures Impact vSAN
vSAN was built with a native ability to handle failures. It can handle transient failures, such as a network misconfiguration, or a full device failure, such as a hard drive failing. vSAN classifies failures in two distinct ways:
• Absent failures
• Degraded failures
The way that vSAN handles a failure depends on its type. The following sections describe these two types of failures.
