Two failure events that cause vSAN to start rebuilding components immediately on the VxRail system are:

ESXi host failure

Capacity device failure

When an ESXi host fails, vSAN detects the loss of the host and initiates the rebuilding of the affected components to maintain data availability and integrity. Similarly, when a capacity device (such as an SSD or HDD) fails, vSAN starts the rebuild process to ensure that data remains protected and accessible.

When deploying a VxRail Cluster with an existing customer-supplied vCenter Server, two key considerations are:

Supports Enhanced Link Mode with other VxRail-managed vCenter Servers: This allows the existing vCenter Server to link with other VxRail-managed vCenter Servers, providing a unified management interface across multiple vCenter instances, enabling seamless operations and better scalability.

Uses customer-defined procedures for vCenter LCM (Lifecycle Management): Since the vCenter Server is customer-supplied, the procedures for upgrading and maintaining it are defined and managed by the customer, rather than being automatically handled by VxRail's built-in lifecycle management tools.

The deployment architecture used for these clusters, where there is only one vSphere Distributed Switch object for both clusters in vCenter, is "External vCenter Server with external DNS." This setup allows for centralized management of multiple clusters and network resources using a single vSphere Distributed Switch, facilitated by an external vCenter Server and DNS configuration.
