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 VxRail Sizing Tool validates that the recommended model can accommodate the VDI workload, helping ensure the proposed configuration meets performance requirements even with limited initial information.

In the VxRail Sizing Tool, when enabling compression on VxRail vSAN, the default Compression Filter ratio is set to 2:1. This means that the tool assumes a 2:1 data reduction ratio due to compression, effectively halving the storage requirements for the specified workload. This default setting helps in estimating the storage capacity needed for the deployment, though actual compression ratios may vary based on the specific data characteristics.

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.).

A single Shared Witness Appliance can support up to 64 VxRail 2-node clusters, enabling efficient management and resource consolidation in multi-cluster 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.

Live Optics collects and provides detailed virtualization, storage, and network workload metrics that can be imported into the VxRail Sizing Tool to inform accurate sizing and planning.

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 Sizing Tool focuses on the specific workload requirements provided, sizing the cluster based on single or combined workload profiles rather than price considerations.

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.
