ESXI 8.0 over view and Installation Requirements

Updated: Oct 28

In this blog we will see the ESXi 8.0 installation requirements.


An image for esxi 8.0 will have following partitioning.


ESXi System Storage

The ESXi 8.0 system storage layout consists of four partitions:

ESXi Hardware Requirements

1) Supported server platform . http://www.vmware.com/resources/compatibility

2) ESXi 8.0 supports a broad range of multi-core of 64-bit x86 processors. For a complete list of supported processors, see the VMware compatibility guide at http://www.vmware.com/ resources/compatibility.

3) ESXi 8.0 requires the NX/XD bit to be enabled for the CPU in the BIOS. VMware ESXi Installation and Setup VMware, Inc. 16

4) ESXi 8.0 requires a minimum of 8 GB of physical RAM. Provide at least 12 GB of RAM to run virtual machines in typical production environments.

5) To support 64-bit virtual machines, support for hardware virtualization (Intel VT-x or AMD RVI) must be enabled on x64 CPUs. n One or more Gigabit or faster Ethernet controllers. For a list of supported network adapter models, see the VMware Compatibility Guide at http://www.vmware.com/resources/ compatibility.

6) ESXi 8.0 requires a boot disk of at least 32 GB of persistent storage such as HDD, SSD, or NVMe. A boot device must not be shared between ESXi hosts.

7) SCSI disk or a local, non-network, RAID LUN with unpartitioned space for the virtual machines.

8) For Serial ATA (SATA), a disk connected through supported SAS controllers or supported on-board SATA controllers. SATA disks are considered remote, not local. These disks are not used as a scratch partition by default because they are seen as remote. Note You cannot connect a SATA CD-ROM device to a virtual machine on an ESXi host. To use the SATA CD-ROM device, you must use IDE emulation mode.



ESXi Booting Requirements

In vSphere 8.0, support for legacy BIOS is limited and booting ESXi hosts from the Unified Extensible Firmware Interface (UEFI) is recommended. With UEFI, you can boot systems from hard drives, CD-ROM drives, or USB media. vSphere Auto Deploy supports network booting and provisioning of ESXi hosts with UEFI. If your system has supported data processing units (DPU), you can only use UEFI to install and boot ESXi on the DPUs.
