Book course: 6-23 Fibre Channel SAN Components Using SAN switches, you can set up path redundancy to address any path failures from host server to switch, or from storage array to switch. 6-25 Multipathing with Fibre Channel By default, ESXi hosts use only one path from a host to a given LUN at any one time. If the path actively being used by the ESXi host fails, the server selects another available path.

The trigger that can be used to quickly identify the issue and alert the administrator so that the issue can be resolved is:

Lost Storage Connectivity

This alert is triggered when an ESXi host loses connectivity to storage devices. In this case, it would alert the administrator to the inconsistent connectivity states of the Fibre Channel adapter12.

When configuring vCenter High Availability (HA), two of the requirements for the active, passive, and witness nodes are that network latency must be less than 10 milliseconds, which ensures reliable communication between them; and they must have a minimum of a 1 Gbps network adapter, which provides sufficient bandwidth for data replication.
