Deploying ESXi to a local hard drive
Use these procedures to deploy VMware ESXi 5.5 to a locally installed hard drive on a Flex System x240 Compute Node. It illustrates how to learn a server pattern from an existing server, modify the extended UEFI-settings category pattern for that server pattern, and how to install VMware ESXi.
VMware ESXi 5.5 requires memory-mapped I/O (MMIO) space to be configured within the initial 4 GB of the system. Depending on the configuration, certain systems attempt to use memory higher than 4 GB, which might cause a failure. To resolve the issue, you can increase the value of the MM Config option to 3 GB through the Setup utility for each server on which VMware ESXi 5.5 is going to be installed.
An alternative is to deploy a server pattern that contains one of the predefined extended UEFI category patterns that is related to virtualization, which sets the MM Config option and disables the PCI 64-bit resource allocation.
