VMware ESXi 5 installation Requirements

The following article would give you a brief overview of VMware ESXi Hpyervisor and describe the requirements and step by step guide to VMware ESXi 5 installation.

What is VMware ESXi

    • VMware ESXi is a type 1 Hypervisor which runs directly on your hardware
    • It is “the operating system”
    • Talks directly to your hardware including NIC and storage controller

 

Requirements:

    • 64-bit CPU with Intel VT or AMD-V enabled
    • 2098MB of RAM is the minimum but likely you’ll want 8GB+
    • Gig-E or 10Gig-Ethernet controller

 

  • vSphere 5.0 supports booting ESXi hosts from the Unified Extensible Firmware Interface (UEFI). With UEFI you can boot systems from hard drives, CD-ROM drives, or USB media.
  •  ESXi can boot from a disk larger than 2TB provided that the system firmware and the firmware on any addin card that you are using supports it.
  • Check hardware compatibility (HCL/HCG) at www.vmware.com/go/hcl
  • ESXi can be installed and run from VMware Workstation or Fusion (for testing purpose only)
  • VMware Fault Tolerance (FT) has more specific hardware requirements.
  • vSphere storage has it’s own set of requirements

 

What Happened to ESX Server?

  • ESX Server has been deprecated/discontinued
    • Redhat Linux-based service console required more frequent updates and had a larger attack surface
    • Maintaining two platforms didn’t make sense
    • Took longer to install and boot
    • Used more resources of the host

 

  • ESXi type-1 hypervisor
    • Thinner
    • Less updates needed
    • More secure as less codes to patch
    • Still has a very thin built-in local CLI
    • Loads and installs super-fast
    • Performs all the advanced features of ESX
