Shut up and drive! Let’s GO! To iPXE and Beyond

hardware 3x Super Micro Server + 1 NUC NUC with 16 GB RAM Running all Server Roles + Crap Network Emulator 1x 6 Core with 128 RAM 1x 8 Core with 128 RAM 1x 16 Core with 128GB RAM Johan’s two Pelican cases with 15 Dell’s with 32GB of RAM Each Totalling ~1.5 TB of RAM

Infrastructure at a glance 1x Server VLAN 1x Active Directory DC 1x 1702 Current Branch ConfigMgr on Server 2016 DP Locally iPXE Anywhere Solution BranchCache for OSD Toolkit StifleR Enterprise 1.5 1x Server 2008 with Network Emulator for Windows Toolkit (Yeah, its a GUI) Set to 15Mb/s and half % packet loss – Can be much slower, just time consuming 1x Client VLAN 100 Hyper-V Gen2 VM’s with 3GB of RAM each + Johans 300 Set to PXE Boot on startup

Network DIagram

The ”only” challange in this demo Spread the load over 60-75 minutes Bandwidth – Not so much CPU – BranchCache & Image Disk IO With real HW, this is not an issue…

Ipxe – Network booting awesomeness Boot from the DP or IIS servers with HTTP Why is it bad to have local boot images? Security – Who protects the boot images? Slow – Need to distribute them first! Doh!

Getting started with ipxe & sccm http://ipxe.org/howto/sccm http://www.thesccm.com/ipxe-sccm/ http://www.dell.com/support/article/us/en/19/HOW12285 /how-to-configure-pxe-booting-over-uefi-on-a- poweredge-without-using-server-2012-and-windows- deployment-services?lang=EN

WinPE: BranchCache for OSD

Scripted Startup – What can go wrong? #1 startup then boot to PXE –> iPXE -> should reach WinPE in ~5 mins #1 starts TS -> pulls down WinPE again (to serve others) ~ 5 mins #1 starts on install.wim #2-5 starts after 10 minutes at the same time #6-25 starts after 15 minutes #26-100 starts after 20 minutes All complete caching 60mins into session Hammertime + Apply OS Machine 101 – 401 Boots with 10sec interval

Bare metal Issues IP Helper or DHCP? The more UDP the higher risk Get 100+ iPXE boot files @200KB over TFTP (works great!) Get 100+ wimboot.efi files over HTTP Get 100+ BranchCache V2 hashes @250KB (iPXE Timeout) Get 100+ Policy Items for ConfigMgr over HTTP (Timeout?)
