The document discusses the architecture of the HP Blade Workstation Solution. It consists of three core components: the HP ProLiant xw460c Blade Workstation located in the data center, a client access device located at the user's desktop, and HP Remote Graphics Software. The blade workstation executes applications and includes high-performance processors, memory, and graphics. HP RGS transmits the desktop image to the client access device and captures user input. The client access device can range from a thin client to a workstation. HP RGS allows the client access devices to be located remotely while providing a local experience.

1. 1 The HP Blade Workstation Solution
Architecture
1-1 Introduction
The HP Blade Workstation Solution featuring the HP ProLiant xw460c Blade Workstation
represents a new paradigm in workstation computing. Rather than placingInstead of housing
the computing power of the workstation’s computing power at on the user’s desktop, the
computing power, in the form of blade workstations, is moved to the data center where the
workstations can be more easily, securely, and inexpensively managed. Only a client device—a
small- form- factor boxcomputer, displaysmonitor, mouse, and keyboard—is leftremains on the
user’s desktop.
The data center can be nearby geographically close to the user, or, for business continuity
reasons, more distant. Standard networking technology connects the blade workstations to the
client access devices. At a conceptual level, the network can be viewed as a long set of
keyboard, mouse, and video cables.
The HP blade workstation solution consists of three core components: The HP ProLiant xw460c
Blade Workstation, the a client access device, and HP Remote Graphics Software (HP RGS).
as shown in See Figure 2-1.
Figure 2-1 The HP Blade Workstation Solution core components
The blade workstation, which executes the user’s applications, is designed for maximum
performance, and can be configured with one or two high- speed Intel® Xeon® processors.
The blade workstation also includes high- speed memory and a dedicated graphics adapter that
generates the interactive desktop image.
Comment [SDT1]: Should be Chaper 2, with
all the subsections renumbered to 2-x.
Comment [SDT2]: How about just titling this
chapter “Architecture”? The book title already
includes the product name. In addition, you
won’t have the redundancy with subsection
titles like, “1-2 Architecture of the blade
workstation solution.”
Comment [SDT3]: Should only be one space
after the period at the end of a sentence.
Comment [SDT4]: Avoid forming the
possessive of generic nouns and inanimate
objects.
Comment [SDT5]: Would be better as a
bullet list for readability.
Comment [SDT6]: Use Figure Title font.
GLOBAL COMMENT. NOT MARKED AGAIN.
Comment [SDT7]: Change “user’s” to
“user.” Hyphenate client-access device.
Comment [SDT8]: What is the colorful
squiggly line with the number 1 in this figure?
Might be good to call that out.

2. Using HP RGS, the desktop image is transmitted over the network to the user’s client- access
device, which displays the desktop image locally. HP RGS was designed to provide extremely
fast capture, compression, and transmission of the desktop image over standard TCP/IP
networks. HP RGS is also used to capture the user’s keyboard & and mouse inputs, and
send them to the blade workstation for processing by Windows and the applications running on
the blade workstation.
The client- access device is typically a small- form- factor computer, and can be anything
range from a thin client, to a desktop computer, to a workstation. The HP dc72 Blade
Workstation Client is the newest client- access device for the HP’s blade workstation solution.
To minimize cost and maintenance, the HP dc72 Blade Workstation Client is based on
embedded Linux, which is installed on a solid- state disk. To improve data security, there
arethe HP dc72 is not equipped with no floppy diskette drives or optical drives.
Comment [SDT9]: Based on the SDT3
comment, I would consider moving this just
underneath the figure as a legend (or ahead
of the figure, if it relates to multiple figures,
maybe as a note)
Comment [SDT10]: Avoid using subjective
modifiers.
Comment [SDT11]: Do not use an
ampersand for the word and (unless it is part
of a company name).
Comment [SDT12]: Do not use an
apostrophe with the company name. Instead,
use "HP" as an adjective. Also, do not use
an apostrophe to form the possessive of
product, program, or service names.

3. Because of the performance and features ofThe HP RGS enables, the client- access devices
can to be located anywhere, from being proximateeither close to the data center to beingor at
a remote sites, while still providing a “just like local” experience for the user. Additionally,
HP RGS supports remote collaboration by permitting enabling the desktop images from a single
blade workstation to be sent to multiple client- access devices. Figure 2-2 shows how the
blade workstations in the data center can be allocated to users at multiple sites.
Figure 2-2 Connectingion of blade workstations to client- access devices at multiple sites
Comment [SDT13]: Hyphenate “client-access
devices.” Lowercase “data center” in the
description. Also, “the” is kind of overused in
the description. Would be less cumbersome to
say, “HP RGS is used over standard TCP/IP
networking to connect remote client-access
devices to blade workstations in the data
center.”
Comment [SDT14]: Gerund form is
preferable, less passive.
Comment [SDT15]: Figure title should be
before the figure.

4. 1-2 Architecture of the blade workstation solution
1-2-1 Blade Workstation Architecture
At the heart of the HP Blade Workstation Solution is the HP ProLiant xw460c Blade
Workstation. The block diagram of the blade workstation is shown in Figure 2-3.
Figure 2-3 Block diagram of the HP ProLiant xw460c Blade Workstation
The HP ProLiant xw460c Blade Workstation is optimized for performance, including with the
following components:
 One or two Intel Xeon dual core processors running at clock ratesspeeds up to 2.66
GHz.
 The NVIDIA Quadro FX high- performance graphics adapter.
 Up to 16 GBytes of error- correcting, Double Data Rate 2 (DDR2), 667-MHz
memory running at 667 MHz
. Note: that Windows XP can only access the first 4 GBytes of memory.
 Two Broadcom Ethernet ports, NIC1 and NIC2, providing data rates up to 1
Gbits/sec.
 One or two high- speed Sserial- Aattached SCSI disk drives.
The blade workstation has two video controllers:, the an ATI video controller (ATI RN50)
video controller (“ATI video controller”), and the a high-performance graphics adapter (NVIDIA
Quadro FX) graphics adapter (“NVIDIA graphics adapter”). The function of the two video
controllers is described in the next section.
On the front panel of the blade workstation is the Llocal I/O Cconnector, which provides a
video signal (originating from the ATI video controller), two USB ports, and a serial (RS-
232) lineconnector. By connecting a displaymonitor, keyboard, and & mouse to the Llocal

“Integrated Lights-Out, version 2” to “iLO 2”
(don’t need to call out in figure, you’re
already calling out in body text)
Please note that the capitalization between
figures is not consistent. Here there is a lot of
initial-cap usage, where previous figures used
all lowercase. This needs to be made
consistent.
Comment [SDT18]: Use Note format.
Comment [SDT19]: It would be best to
cross-reference the actual section title here, in
case for some reason the sections are moved
around. Example: See the section titled "HP
RGS" in Section 1-4.
Comment [SDT20]: Always use a comma
before the last item in a series (example:
one, two, and three).

Windows console). The serial line connector is for trained personnel to perform advanced
diagnostics by connecting to connect a null modem serial cable. and perform advanced
diagnostic procedures.
The Integrated Lights-Out version 2 (iLO 2) management processor is HP’s industry-leading
a remote, out-of-band management technology widely used in HP ProLiant and HP Integrity
servers. The iLO 2 technology has been integrated into the blade workstation to provide the
same industry-leading remote management capabilities. The iLO 2 management processor
implements uses a web server, allowing you to access the remote management capabilities of
the blade workstation’s remote management capabilities simply by pointing your browser (using
HTTPS) to the IP address of iLO 2.
Comment [SDT21]: Marketing jargon not
appropriate for this type of content.
Comment [SDT22]: Try not to start a
sentence with an acronym.

6. 1-2-2 The Remote Console Mode BIOS setting
Operation of the two blade workstation’s two video controllers is governed by the user-settable
defined BIOS parameter, Remote Console Mode, which has three possible configurable settings:
1. Admin Mode
2. User Mode
3. Setup Mode
The next fourfollowing sections discuss describe how to configure how to set Remote Console
Mode settings, and how these settings affects the Windows console display of the Windows
console.
Setting Remote Console Mode
The Remote Console Mode can be set by the user during a Windows boot.booting of
Windows. During bootingWhen Windows boots, the boot console is generated by the ATI
video controller independent of the Remote Console Mode (seeas shown in Figure 2-4).
The NVIDIA graphics adapter is detected during boot,ing but is not used.
Figure 2-4 Boot console generation by the ATI video controller boot-console generation
As shown abovein Figure 2-4, the boot console can be viewed in two ways:
1. On Using the Llocal I/O Cconnector’s video- output signal.
2. The boot console can also be viewed throughUsing the iLO 2 networking port (by pointing
a browser to the iLO 2 IP address).
Comment [SDT23]: Add cross references to
the subsection that describes each mode.
Comment [SDT24]: Should be a bullet list.
Also, it doesn’t appear the proper style has
been applied (bullet list). The font should be
9 pt instead of 10 pt.
Comment [SDT25]: Please change all
occurances of the following in the figure:
“USB x2” to “USB x 2”
“Mbytes” to “MB”
“Integrated Lights-Out, version 2” to “iLO 2”
Comment [SDT26]: Should be bullet list.

7. To set Remote Console Mode, press the F9 key on your keyboard when prompted during
boot,ing and then select the desireda mode (see as shown in Figure 2-5).

Formatted: Font: Futura Bk, Font color: Black
Comment [SDT27]: Don’t really think the
procedural recap is necessary in the figure, but
if you’re going to use it, please change to
something like, “To set the Remote Console
Mode (User Mode, Admin Mode, or Setup
Mode), press the F9 key during boot.” This
changes the instruction from passive voice to
active voice.

8. Admin Mode
If When the Remote Console Mode is set to Admin Mode, the ATI video controller, which
previously generated the boot console, will then generates the Windows console (seeas shown
in Figure 2-6). In Admin Mode, the NVIDIA graphics adapter is not visible to the Windows
operating system and is not used.
Figure 2-6 Generation of the Windows console by the ATI video controller in Admin Mode
As shown in Figure 2-6, in Admin Mode, the Windows console can be viewed in three ways:
in Admin Mode:
1. On Using the Llocal I/O Cconnector’s video signal.
2. Through Using iLO 2 in from a browser window.
3. Using HP RGS through one of thefrom the network ports selected previously for use by
HP RGS, (NIC1 or NIC2), whichever network port is selected for use by HP RGS.
NOTE: 1Because the NVIDIA graphics adapter is faster than the ATI video controller, is not as fast as the
NVIDIA graphics adapter, remote performance using HP RGS will beis slower in Admin Mode. For best
remote performance, the NVIDIA graphics adapter should always be used for remote graphics as described
in the next section.

numbered. GLOBAL COMMENT. NOT MARKED
AGAIN.
Comment [SDT31]: Use specific subsection
title cross reference, if possible.

9. User Mode
When Remote Console Mode is set to User Mode, the NVIDIA graphics adapter will generates
the Windows console as shown in Figure 2-7. In this mode, the Windows console can only
be viewed using HP RGS through NIC1 or NIC2. Because the ATI video controller is
inactive, no Windows console is available on the Llocal I/O Cconnector or through iLO 2.

Comment [SDT32]: See SDT25 comment.
Also, remove “This” from “This ATI controller
is not…”

10. Setup Mode
Setup Mode is similar to Admin Mode in that the ATI video controller generates the Windows
console (as shown insee Figure 2-8). In Setup Mode, the NVIDIA graphics adapter
(,although even though it isn’t used), is visible to the operating system. This visibility allows
the operating system to install the NVIDIA graphics driver the first time the blade workstation is
booted. For more information about the initial blade workstation boot, see Chapter X,
“XXX.”Refer to the Installation and power-on chapter for information about the initial booting of
the blade workstation.
Figure 2-8 In Setup Mode, both video controllers are visible to the operating system
As with Admin Mode, in Setup Mode the Windows console can be viewed in three ways in
Setup Mode:
1. On Using the Llocal I/O Cconnector’s video signal.
2. Through Using iLO 2 infrom a browser window.
3. Using HP RGS from the network port selected previously for use by HP RGS (NIC1 or
NIC2)
5. Using HP RGS through one of the network ports, NIC1 or NIC2, whichever network port is
selected for use by HP RGS.

11. 1-2-3 Interacting with the blade workstation
Above we showed the different ways that the boot console and Windows console can be
viewed based on the three Remote Console Mode settings. Now let’s extend this further by
discussing how the user can interact with the boot console and the Windows console based on
the different ways they can be viewed.
Local I/O Cconnector
Whenever the boot console or Windows console appears on the Llocal I/O Cconnector, the
user can plug inconnect thea Llocal I/O Ccable. Then connect a monitor, keyboard, and
mouse and connect a display, keyboard & mouse to the cable to, allowing the user to
interact with the boot console and the Windows console.
iLO 2 Remote Console
Whenever the boot console or Windows console appears on iLO 2, the user can view & and
interact with the two consoles using by pointing a web browser to the iLO 2 IP address,
selecting the Remote Console tab, and then selecting a specific Remote Console. Figure
2-9 shows the boot console being viewed through the iLO 2’s Integrated Remote Console.
Figure 2-9 Viewing of the boot console using with the iLO 2’s Integrated Remote Console
capability.
HP RGS
Whenever the Windows console is generated by the NVIDIA graphics adapter, you the user can
interact with the blade workstation using HP RGS from a remote client computer.
Comment [SDT36]: This doesn’t seem to be
a very accurate title. Wouldn’t “Viewing the
Windows and boot consoles ” be more
appropriate?
Comment [SDT37]: This whole paragraph is
really not necessary. You could just say,
“There are three ways to view the Windows
console and the boot console. The following
sections describe each method.”
Comment [SDT38]: Should be Head 4.
Comment [SDT39]: The console can’t appear
“on” a connector. Need to reword.
Comment [SDT40]: Can you really connect
KVM to a cable?
Comment [SDT41]: Should be Head 4.
Comment [SDT42]: The console can’t appear
“on” iLO 2. Need to reword.
Formatted: Font: Futura Hv
Comment [SDT43]: This really should be a
three-step procedure.
Comment [SDT44]: Need figure title on top.
Comment [SDT45]: Should be Head 4.
Comment [SDT46]: Don’t we need to tell
them more about how to do this? We did in
the preceding sections.

12. 1-2-4 Blade workstation sleep-state support of sleep
states
The blade workstation supports only two sleep states supported by the blade workstation are
S0 (fully on) and S5 (off, but connected to power) sleep states. From S5, Wake-on-LAN
(WOL) is supported by both built-in Broadcom NICs.
Comment [SDT47]: “Only two” makes the
reader want to say, “that’s it?” Have
rephrased positively.
Comment [SDT48]: Use “embedded” or
“integrated” instead.

13. 1-3 Using HP RGS
HP Remote Graphics Software is a high-performance desktop remote- display technology,. It
which consists of three core elementsprimary parts: The RGS Sender, the RGS Receiver, and
RGS Enterprise Directory Service.
The RGS Sender runs on the HP ProLiant xw460c Blade Workstation and works with the
NVIDIA graphics adapter to capture the display image from the graphics adapter’s frame buffer
at the pixel level. Highly efficient, and visually lossless compression algorithms are applied to
the image, which is sent via through TCP/IP networking to the client- access device for
display. Audio is also captured and sent to the client for playback. Mouse, keyboard, and
USB inputs from the client- access device are forwarded to the Windows operating system on
the blade workstation to be processed.
NOTE: 2The RGS Sender is not pre-installed on the HP ProLiant xw460c Blade Workstation. in the factory
software pre-load. The RGS Sender must be installed by an administrator usingfrom the HP Remote
Graphics Software CD that is shippedincluded with the blade workstation.
The RGS Receiver runs on the client- access device, uncompressing and displaying the images
and playing the audio from the RGS Sender. The RGS Receiver collects mouse and
keyboard inputs for return to the RGS Sender, and provides a remote interface for selected
USB devices. The RGS Sender and Receiver operate in an tightly coupled integrated loop
that provides a highly interactive “just like local” user experience.
The RGS Enterprise Directory Service is an optional component of HP RGS that allows the
administrator to assign blade workstations to specific users, and to save RGS &and blade
workstation client preferences. for the user. RGS Enterprise Directory Service is intended for
large installations deployments to provide an automated, and consistent end-user experience.
For more information on about HP RGS, refer tosee the HP Remote Graphics User’s Guide,
available on the HP Remote Graphics Software CD that is included with your the HP ProLiant
xw460c Blade Workstation.
1-4 Blade workstation infrastructure
This section discusses describes the blade workstation infrastructure, including the HP
BladeSystem c7000 enclosure, and the network devices which that can be installed in the
interconnect module bays in the back of the enclosure.
1-4-1 The HP BladeSystem c7000 Eenclosure
As shown in Figure 2-10, uUp to 16 blade workstations can be installed in an HP
BladeSystem c7000 enclosure (see Figure 2-10). The height of the enclosure is 10U,
enabling Because the enclosure is 10U high, four enclosures (containing up to 64 blade
workstations) can to be installed in a standard 42U high rack.
Comment [SDT49]: Jargon.
Comment [SDT50]: “uncompressing” or
“decompressing” (don’t know about the
pressure connotation there)
Comment [SDT51]: “discusses” implies a
back-and-forth dialogue-type thing. “Describes”
or “details” is more appropriate.

14. Figure 2-10 Up to 16 blade workstations can be installed in the HP BladeSystem c7000
Eenclosure and four c7000 enclosures can be installed in a 42U high rack.
Comment [SDT52]: Already said this in
preceding paragraph.
Comment [SDT53]: Move figure title on top
of figure.

15. While the power supplies for the previous-generation HP ProLiant xw25p Blade Workstation are
external to its enclosure, tThe c7000 enclosure incorporates the power supplies necessary to
power the HP ProLiant cw460c Blade Workstations installed in the enclosure as shown in
Figure 2-11. From one to six power supplies can be installed.
Figure 2-11 Location of the power supplies in the c7000 enclosure
Comment [SDT54]: Probably don’t need to
point this out. You can just say that the
c7000 integrates the PSs into the enclosure.
Comment [SDT55]: Suggested rewrite: “The
c7000 has six power-supply bays integrated
into the enclosure to meet the power
requirements of up to 16 blade workstations
(see Figure 2-11). The number of power
supplies needed depends on the number of
blades installed and the power requirements of
each.”
Comment [SDT56]: Don’t really need the
description in this graphic, since this has
already been said in previous paragraph, but if
you’re going to use it, you should change
“From one to six…” to “Up to six…” and
change “their power requirements” to “the
power requirements of each”

16. 1-4-2 Network connections
The HP Blade Workstation Solution supports these fourthe following network interconnect devices:
1. HP 1Gb Ethernet Pass-Thru Module
2. Cisco Catalyst Blade Switch 3020
3. HP GbE2c Ethernet Blade Switch
4. HP 1/10Gb Virtual Connect Ethernet Module
The interconnect devices are must be installed in interconnect module bay 1 and interconnect
module bay 2 in at the rear back of the c7000 enclosure (seeas shown in Figure 2-12).
The interconnect devices can only be installed in interconnect module bay 1 and interconnect
module bay 2. Interconnect module bays 3 through-8 are not used by the blade workstation
and should remain empty.
Figure 2-12 Location of interconnect module bay1 and interconnect module bay 2
As shown in the blade workstation block diagram in Figure 2-3, blade networking is provided
by NIC1 and NIC2. Each of the 16 NIC1 signals from the enclosure’s 16 device bays is
connected to interconnect module bay 1 in the enclosure. Likewise, each of the 16 NIC2
signals from the 16 device bays is connected to interconnect module bay 2.
Redundancy can beis provided by installing the same interconnect devices in both bay 1 and
bay 2. For example, if NIC1 fails on one of the blades, networking can be re-configured to
utilize use NIC2 on the same blade. Whereas the failed NIC1 signal was available through
the interconnect device in bay 1, the NIC2 signal is available through the interconnect device in
bay 2. This allows network connectivity to be maintained if a particular NIC or interconnect
device fails. or if an interconnect device fails.
Comment [SDT57]: Should be bullet list.
Comment [SDT58]: Really shouldn’t show
OA modules until we’ve talked about them in
the text. Can we delete the OA module
reference from this figure, and then use the
same figure AFTER we talk about OA
modules, but delete the reference to
interconnect bays?
Comment [SDT59]: Change “rear of
enclosure” to “back view of c7000 enclosure.”

17. 1-4-3 The Onboard Administrator Module
The Onboard Administrator module is a management controller that resideslocated below the
interconnect module bays (seeas shown in Figure 2-12). The Onboard Administrator
controller communicates with the iLO 2 management processors on each server blade to form
the core of the management architecture for the blade enclosure. Customers have the option
of installingYou can also install a second Onboard Administrator module in the c7000 enclosure
to act as a completely redundant controller in an active-standby mode. Administrators You
can access the Onboard Administrator through the LCD display (Insight Display) on the c7000
enclosure’s LCD display (the Insight Display – (see Figure 2-13), or through a web browser,
or through a command-line interface.
Figure 2-13 The Onboard Administrator’s Insight Display.

The features of the HP dc72 Blade Workstation Client are features:
1. Intel Celeron 3.06-GHz processor
2. 512 MBbytes of RAM
3. 512 MBbytes SATA solid- state Disk-On-Memory (DOM)
4. No floppy diskette drive, hard drive, or optical drive
5. Quad display support
6. NVIDIA Quadro NVS 285 (PCI-Express)
7. NVIDIA Quadro NVS 280 (PCI)
8. Blade Workstation Embedded OS
9. Pre-installed HP RGS Receiver
Comment [SDT60]: This is phrased in the
negative. Makes it sound like their not getting
something. Might want to rephrase to say why
that’s an advantage (i.e., security).
Comment [SDT61]: Should be bullet list.
