D-VXR-DS-00 Dell VxRail Design Questions and Answers

VD-4510 with 3 NVMe SSDs and 25 GbE networking is a valid ESA node configuration optimized for performance with NVMe storage and higher bandwidth.

E660N with 3 NVMe SSDs and 10 GbE networking also qualifies as a valid ESA node configuration balancing NVMe storage with 10 GbE network connectivity.

Predefined network profiles for vSphere Distributed Switch in VxRail typically include configurations such as 2x10 GbE integrated NICs, 2x25 GbE PCIe NICs, and 4x25 GbE integrated NICs to accommodate various performance and connectivity requirements.

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.

The cluster is replacing an existing infrastructure, which aligns with a Technology Refresh purpose, and supporting Hadoop and Tableau workloads fits the Big Data use case in the VxRail Sizing Tool.

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

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 vSAN witness virtual appliance requires connectivity to the Management network for administrative access and the dedicated vSAN witness network to handle witness traffic for cluster quorum.

The two types of port groups on a vSphere Distributed Switch are Virtual Machine port groups (for VM traffic) and VMkernel port groups (for host management, vSAN, vMotion, etc.).

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.
