LLDP (Link Layer Discovery Protocol) must be configured on the ToR switch to enable automated discovery of VxRail nodes during deployment.

Only a new VxRail-managed vCenter Server platform supports the built-in vCenter HA capability required for high availability in VxRail environments.

Assigning resource-intensive networks like vSAN to the higher speed uplinks ensures that critical traffic benefits from the best available network performance, optimizing throughput and maintaining security by separating traffic types appropriately.

When deploying VxRail with an existing customer-managed vCenter, the Cluster Object must be preconfigured to provide a container for the new VxRail nodes and resources during deployment.

The Site Planning Guide provides detailed information on power and rack space requirements to ensure proper physical infrastructure planning for VxRail deployments.

For proper network resolution in a VxRail deployment using external DNS, valid lookup records are required for vCenter Server, ESXi hosts, and discovery addresses to ensure all critical components can be located and communicate correctly.

For erasure coding with a Failure to Tolerate (FTT) of 2 in a vSAN ESA cluster, a minimum of 5 nodes is required to provide the necessary redundancy and data protection.

The Pre-deployment Checklist from the VxRail Configuration Portal is used to validate site readiness by ensuring all necessary prerequisites and environment conditions are met before deployment.

Selecting 1 failure tolerance with RAID 5 (Erasure Coding) causes each front-end write to generate 4 backend I/Os due to the parity calculations and data striping involved, impacting storage performance accordingly.

The witness appliance is the same for both vSAN ESA and OSA architectures, providing consistency across deployments.

The witness can be managed by a separate vCenter server than the one managing the VxRail cluster, allowing flexible management options.

The VxRail Solution Summary report provides a concise overview of the configured solution, serving as an input for Sales Ordering tools to facilitate procurement and deployment.

To maintain compatibility in a vSAN OSA cluster, node types that match the existing architecture, such as E660N and E660, can be added, ensuring consistent hardware and software support.
