When adding VxRail nodes based on a different chipset (e.g., AMD vs. Intel) to an existing cluster, it is necessary to enable VMware Enhanced vMotion Compatibility (EVC) mode. EVC ensures CPU compatibility for vMotion by masking certain CPU features, making it possible to add nodes with different processors to the same cluster without causing compatibility issues.

Steps:

Enable VMware EVC mode on the existing cluster.

Ensure all cluster nodes meet the EVC requirements.

Add the new AMD-based nodes to the existing cluster.

The vSphere integrated component that must be installed on the VxRail cluster to run containers is VMware Tanzu. VMware Tanzu enables Kubernetes container orchestration within a VMware environment, integrating with vSphere to provide a platform for managing containers alongside virtual machines. This allows administrators to deploy and manage containerized applications using the same tools and processes they use for VMs.

The recommended vSAN automatic rebalancing threshold by VMware is 20%. This threshold ensures that vSAN automatically initiates rebalancing operations when the storage utilization across the disks in the vSAN datastore becomes uneven beyond this threshold, maintaining optimal performance and storage efficiency.

The maximum number of remote vSAN data stores a client cluster can mount using vSAN HCI Mesh is 6. VMware vSAN HCI Mesh allows for the mounting of remote vSAN datastores to provide flexible storage solutions and scalability. This feature enables multiple clusters to share storage resources efficiently.

Dell VxRail Technical Guide

When a VM is configured with hard disks totaling 100 GB and uses a RAID 5 vSAN Storage Policy, the total space consumed on the vSAN Datastore is approximately 133 GB. RAID 5 in vSAN requires additional space for parity, which is typically about 1.33 times the original data size. This means that for 100 GB of allocated space, the actual consumed space will be around 133 GB, accounting for the data and parity overhead.

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.
