ESXi Frequently Asked Questions

 

What is the minimum RAM required to install VMware ESXi on Dell PowerEdge servers?

The minimum RAM required for installing ESXi on Dell PowerEdge servers is 8 GB.

VMware recommends a minimum of 4 GB RAM to install ESXi. However, if you install ESXi on Dell PowerEdge systems with 4 GB RAM, the installation may fail due to insufficient memory. This is because, a part of the RAM is occupied by the BIOS.

Why are network adapters not detected during ESXi installation on PowerEdge servers?

Cause:

This issue occurs due to one of the following reasons:

  • The ESXi image does not contain the latest version of network drivers, for Network Daughter Cards (NDCs) or network adapters used in Dell servers.
  • PowerEdge server does not have an NDC installed.
  • The NDC installed on the PowerEdge server is faulty.
  • PowerEdge server has an NDC installed, but the NDC setting is disabled in the BIOS/UEFI.

Resolution:

  1. Use the latest available Dell customized ESXi image, which contains drivers for all NDC or network adapters supported on Dell PowerEdge servers.
    Note: For more information about downloading the Dell customized ESXi image, see WMware ESXi Deployment Guide.
  2. Check if the NDC is working correctly.
  3. Check if the NDC setting is enabled in BIOS/UEFI. Note: For more information about installing and configuring the NDC on a PowerEdge server, see Dell PowerEdge hardware Owner’s Manual at dell.com/poweredgemanuals.

Why are target devices not available in the Disk Selection wizard of ESXi installer?

Cause:

This issue occurs due to one of the following reasons:

  1. There is no PowerEdge RAID controller or Internal Dual SD Module (IDSDM) installed on the server.
  2. There are no PowerEdge RAID controllers installed in the IDSDM.
  3. The drivers for the Storage controllers are not available in the ISO image.
  4. In the BIOS configuration utility, IDSDM is disabled.
  5. In the BIOS configuration utility, the Integrated RAID controller is disabled.
  6. If the Storage controller is set to RAID mode, and virtual disks are not created with the hard drives associated with the controller.

Resolution:

  1. Use the latest available Dell customized ESXi image, which contains drivers for all the supported storage controllers on Dell PowerEdge servers.
  2. Ensure that the SD card is installed in the IDSDM card before installing the IDSDM card on the server. In the BIOS configuration utility, set IDSDM to Enable.
  3. In the BIOS configuration utility, ensure that Integrated RAID Controller is set to Enable.
  4. While installing ESXi 5.x, ensure that the USB 3.0 option in the BIOS settings is set to Disable.
  5. If the Storage controller is set to RAID mode, ensure that the virtual disks are created with the hard drives associated with the controller.

Figure 3: Target devices not displayed

Why does ESXi 5.x display the number of processors incorrectly with the Intel Xeon processors in the Dell 13th generation BIOS settings?

Cause:

This issue occurs if the Snoop mode option is set to Cluster on Die in the BIOS Memory Settings screen of a dual processor system.

Resolution:

To display the accurate number of processors, ensure that the Snoop mode option is not set to Cluster on Die in the BIOS Memory Settings screen.

Why are keyboard inputs not received by ESXi 5.x installer?

Cause:

This issue occurs because ESXi 5.x does not have USB 3.0 drivers. When USB 3.0 option is enabled in the BIOS settings, keyboard inputs are not received by the ESXi 5.x installer due to lack of drivers. This results in an installation failure, as shown in Figure 4.

Resolution:

  1. While installing ESXi 5.x, ensure that the USB 3.0 option in the BIOS settings is set to Disable.
  2. Ensure that you use the ESXi version, which carries USB 3.0 enablement.
