VMware vSphere Update Manager

VMware vSphereUpdate Manager automates patch management and eliminates manual tracking and patching of vSphere hosts and virtual machines. It compares the state of vSphere hosts with baselines, then updates and patches to enforce compliance.

Step 1: Install update manager into vCenter Server

VMware vSphere Distributed Resource Scheduler

VMware DRS dynamically balances computing capacity across a collection of hardware resources aggregated into logical resource pools, continuously monitoring utilization across resource pools and intelligently allocating available resources among the virtual machines based on pre-defined rules that reflect business needs and changing priorities. When a virtual machine experiences an increased load, VMware DRS automatically allocates additional resources by redistributing virtual machines among the physical servers in the resource pool.

VMware vSphere Fault Tolerance

VMware vSphere Fault Tolerance (FT) provides continuous availability for applications in the event of server failures by creating a live shadow instance of a virtual machine that is always up-to-date with the primary virtual machine. In the event of a hardware outage, vSphere FT automatically triggers failover—ensuring zero downtime and preventing data loss.
After failover, vSphere FT automatically creates a new, secondary virtual machine to deliver continuous protection for the application.

Step 1: Prepare VM

Using VMware vSphere High Availability (HA)

VMware HA will works on a cluster that running at least two ESXi hosts in a situation host failure, without failing VMs that runs on that Host. (Depend on the available cluster resources after a host failure will not run all the VMs, therefore you can priorities most impotent VMs that should run in a situation like this)

Step 1: Setup a Cluster

Migrating Virtual Machines (VMware Vmotion)

VMware vSphere live migration allows you to move an entire running virtual machine from one physical server to another, without downtime. The virtual machine retains its network identity and connections, ensuring a seamless migration process.

Transfer the virtual machine’s active memory and precise execution state over a high-speed network, allowing the virtual machine to switch from running on the source vSphere host to the destination vSphere host. This entire process takes less than two seconds on a gigabit Ethernet network.

  • Automatically optimize virtual machines within resource pools.
  • Perform hardware maintenance without scheduling downtime or disrupting business operations.
  • Move virtual machines away from failing or underperforming servers.vmw-dgrm-vsphere-087b-lg
