VMware vCenter Cluster multiple ESXi CPU, memory, and storage managed.

A VMware vCenter Cluster is a logical grouping of multiple ESXi hosts managed as a single system by vCenter Server, pooling their CPU, memory, and storage resources to provide high availability, load balancing, and efficient resource management for virtual machines (VMs) through features like vSphere DRS, vSphere HA, and vSAN. It acts as a "single pane of glass" for managing these shared resources, allowing VMs to move seamlessly and remain available even if a physical host fails. || Key Concepts __Resource Pooling: Combines CPU and memory from multiple physical servers (hosts) into one large pool, managed centrally by vCenter Server. __Centralized Management: vCenter Server allows administrators to manage all hosts and VMs within the cluster as a single object, simplifying operations. __High Availability (HA): If a host fails, VMs automatically restart on other available hosts in the cluster, minimizing downtime. __Distributed Resource Scheduler (DRS): Automatically balances workloads across hosts by migrating VMs to the most optimal host based on resource utilization, ensuring performance. __vSphere Cluster Services (vCLS): Lightweight agent VMs deployed within the cluster (starting vSphere 7.0 Update 1) that ensure core cluster services like DRS and HA remain available, even if vCenter Server becomes temporarily unavailable. || Benefits __Improved Uptime: vSphere HA ensures continuous operation of critical workloads. __Optimal Performance: DRS dynamically adjusts VM placement for balanced resource use. Simplified Administration: Manage many hosts and VMs from one interface. __Scalability: Easily add more hosts to increase overall capacity. || How it Works __Create a Cluster: In vCenter, you create a cluster object within a data center. Add Hosts: You add ESXi hosts to the cluster, pooling their resources. __Enable Services: You enable features like DRS, HA, and vSAN on the cluster. __Deploy VMs: Virtual machines are deployed onto the cluster, utilizing the combined resources. __vCenter Manages: vCenter, using vCLS, monitors resource usage and host health, orchestrating VM placement and failover.
