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

Both Layer 2 (L2) and Layer 3 (L3) site-to-site connectivity are supported for VxRail stretched clusters.

Configurations with two nodes plus a witness and four nodes plus a witness are supported cluster sizes for stretched clusters, providing fault tolerance across sites.

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.

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.

Validating the environment before deployment ensures readiness and reduces deployment issues.

Sharing configurations between project members facilitates collaboration and consistency.

Validating the configuration settings helps confirm correct setup prior to deployment.

VxRail Dynamic Nodes enable the use of vSAN storage from an existing VxRail cluster.

They support integration with existing supported external storage arrays.

They allow use of external storage alongside local vSAN for tiering and optimized storage management.

The PowerStore 5200T connected via NVMe/TCP supports integration with a VxRail-managed vCenter on the local cluster, enabling optimized storage performance and management within the VxRail ecosystem.

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

VxRail uses JSON-formatted configuration files to define the settings and parameters required to build and deploy a cluster, allowing for structured and machine-readable configurations.

The correct process is to sign up on the Live Optics website, download the collector, and deploy it on a suitable workstation or server in the environment to gather data without impacting the vCenter Server directly.
