Installation (Smart Setup) Guide, Windows Server 2008 R2, v6.5

Smart Update media after the OS installation, in order to obtain the latest HP value-added
software (drivers, tools, utilities, manageability agents) for HP Integrity Servers.
Installing Windows Server 2008 R2 on rx8640 and rx7640 Servers
On rx8640 and rx7640 servers, you must run the reconnect –r command at the EFI shell before
launching the Windows Server 2008 R2 installation. Failure to run this command can result in
the following error message during the installation:
Windows Setup cannot locate valid Hard Drive to store temporary
installation files. To install Windows create more free space on the
hard drive or add a new hard drive.
Install from IRC
If you are using the IRC to remotely install Windows Server 2008 R2 on servers with a graphics
console attached to the local VGA port, complete one of the following:
• Install the OS remotely from a headless console instead. See “Install from a Headless Console”
(page 29).
• Disconnect the local graphics console before you install Windows using IRC, and then
reconnect it afterwards. This method is easy and therefore recommended.
Installing a Windows Guest on an HPVM Host
NOTE: HPVM is not currently supported on Windows Server 2008 R2. It is only supported on
Windows Server 2003 and Windows Server 2008 with SP1 or SP2.
HPVM is a soft partitioning and virtualization technology that provides OS isolation with CPU
allocation and shared I/O. HPVM enables a single Integrity server to emulate multiple virtual
machines running distinct operating systems and environments. The Virtual Machines solution
consists of two components:
• A VM host (the physical system where the virtual machines reside)
• Virtual machines, also known as guests
Virtual machines, or guests, are abstractions of real, physical machines. They are fully loaded,
operational systems, complete with OS, system management utilities, applications, and networks,
all running in the virtual machine environment that you set up for them. You boot and manage
guests using the same storage media and procedures that you would if the guest OS was running
on its own dedicated physical hardware platform.
It is beyond the scope of this document to describe the installation and use of HPVM on Integrity
servers. These topics are covered in detail in HP Integrity Virtual Machines Installation, Configuration,
and Administration found here:
http://docs.hp.com/en/hplex.html#HP%20Integrity%20Virtual%20Machines
If you are interested in implementing HPVM, see this document first. It explains how to install
and configure the host OS, HPVM software, and guests.
Enabling Hyperthreading on HP Integrity Servers
HP Integrity servers now support Intel® Dual-Core Itanium processors. These processors, in
addition to providing two CPUs in the space previously occupied by one, support a new feature
called hyperthreading.
Hyperthreading enables each physical processor to present itself to the OS and applications as
two virtual processors. This means each processor can work on two or more sets of tasks
simultaneously. This feature makes use of resources that would otherwise sit idle, enabling your
HP Integrity server to perform more work in less time.
