For a VxRail environment where Fault Tolerance Method (FTM) is set to Erasure Coding and the Fault Tolerance Threshold (FTT) is set to 1, the minimum number of hosts required is 4. This is because Erasure Coding typically requires a minimum of 4 hosts to distribute the data and parity efficiently while ensuring fault tolerance. The specific setup of Erasure Coding (RAID 5/6) in VxRail environments necessitates this host count to maintain data protection and efficiency.
Starting with vSphere 7.0, the external Platform Services Controller (PSC) is deprecated. Therefore, the correct configuration must use an embedded PSC. Enhanced Linked Mode and vSAN Encryption are both supported with an embedded vCenter Server and embedded PSC.
The VxRail Manager is pre-installed on the first node of a newly shipped VxRail Model G410 system. This is a standard practice to streamline configuration and management processes once the system is powered up and initialized.
