A vSphere cluster is a collection of ESXi hosts that work together to provide better performance, high availability, and resource optimization. Clustering allows multiple hosts to work as a unified system, providing a pool of resources that can be dynamically allocated to virtual machines as needed.

vSphere HA (High Availability): vSphere HA is a key feature of clustering that ensures virtual machines (VMs) are automatically restarted on other hosts in the cluster in case of a host failure. This minimizes downtime by quickly recovering from hardware or software failures. Learning how to configure HA settings, such as admission control policies and VM restart priorities, will be essential for ensuring minimal disruption in production environments.
vSphere DRS (Distributed Resource Scheduler): DRS is another vital feature that helps optimize resource allocation within a cluster. It automatically balances the workloads of virtual machines across ESXi hosts based on available resources such as CPU and memory. You will need to become familiar with DRS affinity rules, which dictate how VMs are placed or moved within a cluster based on policies you define (e.g., keeping specific VMs together or apart).

Understanding Resource Pools

Resource pools allow you to allocate and manage resources such as CPU and memory more efficiently in a clustered environment. Resource pools can be created at both the host and virtual machine levels, giving you granular control over resource distribution. This is particularly important in large environments where you need to prioritize certain workloads or ensure that critical VMs always have the resources they need.

Configuring resource pools and understanding how vSphere handles resource allocation is essential for maintaining a stable environment. With resource pools, administrators can define limits, shares, and reservations for CPU and memory resources, ensuring that virtual machines within the pool receive the necessary resources for their workloads.

There are several key concepts to understand when configuring vSphere HA:

Host Failure Detection: vSphere HA monitors the health of ESXi hosts and automatically triggers failover if a host becomes unresponsive. It can use datastore heartbeats and host isolation detection to determine if a host is down or isolated from the network.
Admission Control: This is a critical setting in vSphere HA that ensures sufficient resources are available to restart virtual machines in case of a host failure. By configuring admission control, you can ensure that the cluster can always handle failovers.

In addition to HA, you should be familiar with the vSphere HA advanced options, such as VM restart priority, which determines the order in which virtual machines are restarted after a host failure. You should also explore VM monitoring options, which allow you to automatically restart virtual machines if they become unresponsive due to a problem within the VM.

Fault Tolerance (FT)

VMware Fault Tolerance provides continuous availability for virtual machines by creating a live shadow copy of the VM on another host. Unlike HA, which involves restarting a VM after a failure, FT ensures that the virtual machine continues running without any downtime during host failures.

FT works by using a concept known as primary and secondary VMs, where the primary VM runs on one host, and the secondary VM runs on another. The secondary VM receives a real-time copy of all CPU and memory operations from the primary VM, ensuring that both VMs are synchronized. If the primary VM fails, the secondary VM immediately takes over without any interruption.

Monitoring the vSphere Environment

Proactive monitoring of your vSphere environment is crucial to detect potential issues before they cause downtime or performance degradation. Tools like vRealize Operations Manager (vROps) or vSphere Performance Charts can help you track the performance of various components in the VMware infrastructure, including ESXi hosts, virtual machines, storage systems, and networks.
