Subnet mask Optional address Gateway Primary DNS Root password Optional Optional Based on IP address and subnet mask Based on IP address and subnet mask IP address, subnet mask, gateway, and DNS network settings can be changed after installation. Secondary DNS server can also be defined. Optional None Must contain 6 64 characters 14-8
Installing ESXi You must have the ESXi 5.1 ISO file on CD, DVD, or USB flash drive media. Boot from the media to start the ESXi installer. Make sure that you select a disk that is not formatted with VMware vsphere VMFS. Choose a volume that has not been formatted with VMFS. 14-9
Booting from SAN ESXi can be booted from SAN: Supported for Fibre Channel SAN Supported for iscsi and Fibre Channel over SAN for certain qualified storage adapters SAN connections must be made through a switched topology unless the array is certified for direct-connect. The ESXi host must have exclusive access to its own boot LUN. Use different LUNs for VMFS datastores and boot partitions. ESXi boot LUN 14-10

Key Points vcenter Linked Mode enables a single vsphere Client to view and manage the inventories of multiple vcenter Server systems. ESXi installation requires little configuration during installation. vcenter Server installed on Windows operating systems can run on physical machines or virtual machines. The vcenter Server Appliance provides the user with a Linux-based solution for managing the virtual infrastructure. Image Builder enables the administrator to create customized ESXi boot images. Auto Deploy is a new method for deploying ESXi hosts, where the ESXi host s state and configuration run entirely in memory. Questions? 14-43
