362 IBM eX5 Implementation Guide Create a drive RAID array before installation. The ServeRAID management interface isaccessible via UEFI settings, by selecting System Settings Adapters and UEFIDrivers. When running the ESXi hypervisor from a USB flash drive, plug it in to the internal USBslot to prevent physical disruption. The internal USB slot is located on the x8 low profilePCI riser card. ESXi formats all local disks in the server when it is initially booted. Remove any local andSAN-attached disks from the system if they contain important data. If ESXi is installed to a USB flash drive, you must add USB Storage to the system bootoption. Placing it on the top of the boot order list decreases system boot time. VMware vSphere 4.1 offers no support for UEFI and therefore is categorized as LegacyOS. Moving Legacy Only up in the boot order list decreases system boot time. If a USB keyboard stops functioning at any time during the ESXi installation, try plugging itin to a separate USB port. You can access more information about the VMware vSphere installation andconfiguration at the following website:http://www.vmware.com/support/pubs/7.9.6 VMware vSphere ESX 4.1The installation of VMware vSphere ESX 4.1 on an x3690 X5 with an attached MAX5 requiresthe installation media of the OS and an available logical drive. Unlike the ESXi with its smallfootprint, you typically install the ESX on a RAID disk array.An x3690 X5 that is attached to MAX5 allows the use of interleaved NUMA nodes. To bootand run ESX on this system, you must enable the allowInterleavedNUMAnodes boot option.Use the following steps to install ESX 4.1 on the x3690 X5 server scaled with MAX5:1. Boot the host from the ESX installation media.2. Press F2 when the installation options panel displays, as shown in Figure 7-58 onpage 363.
