Booting from SAN in vSphere 6.0

Would like to know how to set up Booting from SAN in vSphere 6.0.   Is there any specific advantage if we use this method compared to  booting from physical ESXi Hosts.    The current Storage Array I am working is  HP 3PAR and HP Left Hand.   Would appreciate a step by step guide.

It's often used with blades, that have no storage, and has been replaced by installing ESXi "embedded" onto an SD card or USB Flash drive.

and even the latest blades have options for mirrored SD cards, or small SSD for ESXi host OS.

SAN storage has been seen as expensive to install an ESXi OS, when it's normal use is for VMs.


The majority of the work required is physical you need to create a LUN on your SAN (a small LUN, 500GB etc) this is for the ESXi OS.

You then need to change the hardware settings on the HOST, to ensure it can BOOT from SAN and LUN0, this is in the settings of the HBA on the host server.

and then Just BOOT ESXi OS, and select this "drive" at installation, rather than local hard drive or SD card.
