ESXi is one of the primary components in the VMware infrastructure software suite. ESXi is a Type 1 hypervisor, meaning it runs directly on system hardware without the need for an OS. Type 1 hypervisors are also referred to as bare-metal hypervisors because they run directly on hardware.VMware ESXi and NSX-V Hardware Requirements
Hardware Requirements
RAM
At least 8GB
Disk Space
At least 84GB shared (FC, iSCSI, NFS, or FCoE) or locally attached storage (PATA, SATA, SCSI) Note: Increase the disk space depending on the configuration load requirements for the given GigaVUE-FM instance.
An ESXi hypervisor is provided as a part of VMware vSphere which, in turn, comes with different licensing options for each edition. Each VMware vSphere edition has its own price but VMware also provides a free version of ESXi.
What does VMware ESXi run on : bare metal
ESX runs on bare metal (without running an operating system) unlike other VMware products. It includes its own kernel. In the historic VMware ESX, a Linux kernel was started first and then used to load a variety of specialized virtualization components, including ESX, which is otherwise known as the vmkernel component.
Do hypervisors require an OS
A type 1 hypervisor acts like a lightweight operating system and runs directly on the host's hardware, while a type 2 hypervisor runs as a software layer on an operating system, like other computer programs.
Is VMware an OS or not : VMware ESXi is an operating system-independent hypervisor based on the VMkernel operating system that interfaces with agents that run on top of it. ESXi stands for Elastic Sky X Integrated. ESXi is a type-1 hypervisor, meaning it runs directly on system hardware without the need for an operating system (OS).
ESXi excels for large enterprises needing maximum uptime, performance, and scalability to run demanding workloads. Proxmox suits small to mid-sized organizations requiring virtualization on a budget, with enough power and flexibility for most workloads. Secure Boot for ESXi requires support from the firmware and requires that all ESXi kernel modules, drivers, and vSphere Installation Bundles (VIBs) be signed by VMware or a partner subordinate. Secure Boot is enabled in the BIOS of the ESXi physical server and supported by the hypervisor boot loader.
Is ESXi still free in 2024
Free ESXi (Discontinued) vs.
The free version used the same installation method, meaning you got the enterprise solution with certain features locked out. However, the free version was discontinued in 2024. Here's a comparison of the feature differences between the old free version and the paid version.Run Windows, Linux and other virtual machines with VMware Workstation Pro for Windows and Linux or VMware Fusion for Mac, the industry standard desktop hypervisors.Each virtual machine runs its own operating system and functions separately from the other VMs, even when they are all running on the same host. type 2 hypervisor
In contrast, the type 2 hypervisor is an application installed on the host operating system. It's also known as a hosted or embedded hypervisor.
What is esx vs ESXi : Functionality for both ESX and ESXi is very similar, with the key difference being architecture and management. ESXi is considered the superior product due to its smaller footprint, improved security, and simplified management. vSphere, a suite of virtualization products from VMware, includes ESXi.
Why is ESXi so slow : Slow performance can be caused by misconfigured local storage or SAN array. This article provides steps to determine if the storage for your ESX/ESXi host is properly configured. Symptoms: Slow performance when copying files between Shared VMFS Storage (fibre-channel SAN) and local VMFS storage.
What is better than ESXi
Leading Alternatives to ESXi
Proxmox VE stands out for its web-based management interface, which simplifies the administration of virtual resources, high availability clusters, and backup/restoration processes. Its support for both VMs and containers allows for efficient resource utilization and application deployment. As VMware transitions from ESX to ESXi (and away from the general purpose OS running the COS), the need to run Antivirus/Anti Malware solutions to protect the hypervisor is even further diminished. For more information on the transition from ESX to ESXi, see the VMware ESXi and ESX Info Center.If you're wondering, “Is ESXi free for commercial use” the answer is yes, but with limitations. It's a viable option for running non-critical applications or setting up a virtual lab environment.
Is ESXi going away : Along with the termination of perpetual licensing, Broadcom has also decided to discontinue the Free ESXi Hypervisor, marking it as EOGA (End of General Availability).
