CentOS_7 - Install Minimal Server +20151027

• This is a MINIMAL (CORE) installation intended solely for a FOG Server role
• The resulting image can be deployed to any virtual or physical hardware (hopefully)
• https://wiki.centos.org/FAQ/CentOS7

=-=-=-=-=-
For a Physical FOG Server

i.	Flash & Program System BIOS for ODD Boot
ii.	Install HDD #1 (120+ GiB & zeroed) on first controller port
iii.	Install ODD #1 on last controller port
iv.	Insert CentOS-7-x86_64-NetInstall-1503 CD

=-=-=-=-=-
For a Hyper-V Virtual FOG Server

i.	Create a New Virtual Machine: CentOS_7, Generation 1, 512MB Dynamic Memory, Onboard Network, Create a virtual hard disk
ii.	Boot from CD
iii.	Maximum RAM 2048MB
iv.	1 Virtual Processor
v.	DVD Drive Image File: "CentOS-7-x86_64-NetInstall-1503.iso"

Very nice. I suppose your virtualization server has a very high core speed for only one core to work smoothly.

My development Hyper-V server is a desktop i7 2600 and 16GB memory.

FOG is such a lightweight that I find the storage I/O and Ethernet to be the only bottlenecks.

My physical servers are all running on 2009 Lenovo M58 systems with Pentium E2220 and 2GB ; SATA-II and often 5900rpm at that.

Updated to include mastering for duplication.
