Running local Disks means your Blades are personalised and you are loosing a lot of options you have in Bladecenters. If a Blade HW running funny, just bring down the Blade, change the Server-Profil to a new Blade, that's it. So the installation is only one part of best using Blades in a Bladecenter and we running a big number of ESXi Hosts during the last 15 years and all are running on Storage-Luns as a Boot-Lun. The point is how to automate this better/easier and here we are looking around for other solutions, or we get confirmed to still doing this in the next time.
