VMWare vSphere Hypervisor or ESXi is a powerful operating system that is widely used in data centers and is the de facto market leader for operating systems based on Virtualization Technology. Although advanced features are only available on VMWare vSphere with a commercial license, VMWare also provides the ESXi Hypervisor for free. ESXi Hypervisor is an engine for server virtualization technology based on VMWare vSphere.
Berikut beberapa fitur-fiturnya :
- ESXi scalability, supports clustering up to 64hosts, can run 8000 VMs per cluster, 480 Logical CPUs, 12TB RAM per host, 1024 VMs, 128 CPUs per VM, and 4TB RAM per VM, and also supports hot-add RAM, USB 3.
- Supports Nvidia GRID technology (vGPU and vDGA), which is a technology where VMs can use Nvidia VGA directly to hardware without going through the Hypervisor.
- vCenter scalability, supports up to 1000 hosts and 10,000 VMs. And also supports PostgreSQL database.
- There is vSphere App HA (High Availability).
- There is a vSphere Web Client, which can manage vCenter or ESXi via a web client.
- There is vMotion which can migrate VMs directly via virtual switches, vCenter, and over a distance of up to 150ms RTT.
- There is vSphere Replication which can backup VMs in the event of a disaster.
