Executive overview
The HP Blade Workstation Solution represents a new paradigm in workstation computing. Rather
than placing the workstation's computing power at the user's desk, 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. Centralizing an organization's workstations in the data
center provides many benefits, including.
1. Improved uptime and business continuity—The next-generation remote management capabilities
of the HP Blade Workstation Solution, along with its fault tolerant design and re-provisioning
capabilities, deliver outstanding uptime. To maximize business continuity and interagency
coordination, multi-site blade workstation installations can be created.
2. Enhanced data security—The HP Blade Workstation Solution ensures that your business-critical
data remains in the data center.
3. Reduced IT costs—By centralizing your organization's workstations into the data center and by
taking advantage of HP's robust set of remote management tools, your IT costs can be
significantly reduced.
This paper describes the industry-leading HP Blade Workstation Solution and how this solution
delivers the above benefits as well as many other important benefits. An overview of the solution is
presented first followed by a more detailed description.
HP Blade Workstation Solution overview
The HP Blade Workstation Solution consists of three primary components, as shown in Figure 1:
· The rack-mounted HP ProLiant xw460c Blade Workstation

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® dual-core
processors.1 The blade workstation also includes high-speed ECC memory and a dedicated
graphics card that computes and renders the interactive desktop image.
Using RGS, the desktop image is transmitted over the network to the user's client computer, which
displays the desktop image locally. RGS is designed to provide extremely fast capture,
compression, and transmission of the desktop image over standard TCP/IP networks. RGS is also
used to capture the user's keyboard and mouse inputs and send them to the blade workstation for
processing by the OS and the applications running on the blade workstation. For more information
on RGS, visit http://www.hp.com/go/rgs.
The client computer can range from a thin client to a multi-display desktop computer. The HP dc72
Blade Workstation Client, shown in Figure 2, supports up to four displays, providing the
performance and screen real estate for demanding, data-intensive applications. To minimize cost
and maintenance, the OS of the HP dc72 Blade Workstation Client is installed on a solid-state disk.
To improve data security, there are no floppy or optical drives.
Figure 2. The HP dc72 Blade Workstation Client supports up to four displays.
Because of the performance and features of RGS, client computers can be located anywhere, from
near the data center to remote locations, while still providing a highly-interactive experience for the
user. Additionally, RGS supports remote collaboration by permitting the desktop image from a
single blade workstation to be sent to multiple client computers.

Quad-Core and Dual-Core are new technologies designed to improve performance of multithreaded software products and hardware-aware
multitasking operating systems and may require appropriate operating system software for full benefits; check with software provider to
determine suitability; Not all customers or software applications will necessarily benefit from use of these technologies. 64-bit computing on
Intel architecture requires a computer system with a processor, chipset, BIOS, operating system, device drivers and applications enabled for
Intel® 64 architecture. Processors will not operate (including 32-bit operation) without an Intel 64 architecture-enabled BIOS. Performance will
vary depending on your hardware and software configurations. See www.intel.com/info/em64t for more information.

HP Session Allocation Manager (SAM) can be used to optimize your HP Blade Workstation
Solution deployment by automatically provisioning your blade workstation resources to users. SAM
provides the following capabilities with the blade workstation solution:
· Static and dynamic resource assignments—SAM supports two types of resource assignments:
o
Static resources—With static resources, a user and the user’s client computer are
connected to a pre-defined set of remote computing resources, even when the user
changes location.
o
Dynamic resources—With dynamic resources, users are assigned remote
computing resources from a pool of available computing resources.
These two types of resource assignments provide significant flexibility in meeting the needs of
your users.
· Single log in—SAM simplifies the user experience by allowing the user to log in just once, even if
the user is connecting to multiple blade workstations. Furthermore, with a multi-monitor client
computer, SAM will automatically position the user’s windows on the monitors connected to the
client computer based on pre-configured information. The net result is that logging into the blade
workstation solution is as simple as logging into a single workstation.
· Follow-me roaming—This feature enables users to move to a different location, and be
automatically re-connected to the computing resources they used previously. In doing so, SAM
automatically adapts to different monitor configurations. For example, let’s assume that a user has
four monitors in the office, each displaying the frame buffer from a different blade workstation. If
the user relocates to home, where there is only one monitor, SAM will re-connect to the live
6
sessions on the same four blade workstations as before, but will stack the four frame buffer
windows onto the single monitor for viewing. RGS can then be used to cycle between each of the
four windows.
· Automatic failover—SAM can be configured so that if a blade workstation fails, another blade
workstation will be automatically assigned to the task performed by the failed unit. This feature
works for both static and dynamic connections, maximizing the uptime of the blade workstation
solution and the user’s productivity.
· Automatic client aggregation—The blade workstation solution allows multiple client computers to
be aggregated together to form a single virtual client device, operated by a single keyboard and
mouse. SAM can be configured to perform client aggregation automatically, while ensuring that
each client computer connects to its pre-configured set of blade workstations.
· Ease of administration—SAM provides a web interface that allows all parameters of SAM
operation to be easily monitored and changed from a central location. This is much more efficient
than configuring the blade workstation solution by separately logging into each solution
component.

The HP Blade Workstation Solution contains extensive built-in management capabilities, most of
which are accessible over the network. For example, as shown in Figure 2, the blade workstation
contains the Integrated Lights-Out 2 (iLO 2) management processor, which provides an independent
means of monitoring and controlling each blade. Furthermore, the blade enclosure contains the HP
BladeSystem Onboard Administrator, which allows IT personnel to collectively monitor and manage
the blades installed in an enclosure, such as viewing the operating status of each blade. Figure 7
shows two example management screens for the blade workstation solution.
Figure 7. HP's blade workstations provide industry-leading remote management capabilities.

The blade workstation's remote management capabilities are critical to providing superior uptime
and reducing IT costs by allowing support personnel to quickly detect, diagnose, and resolve
problems. For example, if a user experiences a blade failure, IT personnel can quickly and remotely
assign a new blade to the user from a spare pool, reducing the user's total downtime to minutes.

RGS is more than just a mechanism for sending the blade workstation's desktop image to the client
access device—RGS is a full-function, real-time collaboration tool. In Figure 8, the desktop image is
shared with three remote users, all of whom can interact with the same application running on the
blade workstation.

The HP Blade Workstation Solution ensures that your application data never leaves the data
center—only the desktop image is exported to the users via RGS. Furthermore, the pixels in the
desktop image are encrypted for added security. The interactivity and security provided by RGS
make it ideal for uses such as:
· Financial trading—stream video, market data, and financial trading applications from multiple
workstations to a multi-display trading desk, remote office, or disaster recovery site.
· Classified research and defense—enable highly-secure, high-performance access to sensitive data
and applications.
· Command and control centers—enable a highly-secure, continuous-operation environment by
providing multi-location access to blade workstation resources located in redundant data centers.
· Mobile professionals—enable professionals to efficiently work locally or remotely so they can live
where they choose and work conveniently through an Internet connection.
· Scientific research and visualization—interact with high-performance compute and visualization
simulations from an office and collaborate with colleagues in real-time.
· Support—provide application support to end users by connecting to existing user sessions with
system administrator rights to troubleshoot and resolve issues.
· Classroom training—share live training sessions with one or many students at local or remote
campuses.
