To ensure high availability (HA) of ACOS, you need to configure some parameters of the ESXi host in vCenter and deploy the I/O rerouting script in the SCVM.
I/O rerouting refers to the process of redirecting the I/O flow of a virtual machine that runs business applications to a remote SCVM for recovery in the event of a local SCVM failure, thereby ensuring high availability for business operations.
