PC Blade Virtualization Configuration Guide
The combination of ClearCube PC Blades and management software with industry-standard virtualization technology gives IT managers a new way to more efficiently use their computing assets. This guide outlines the various technical requirements and options to deploy virtualization solutions on PC Blades from ClearCube Technology. It describes the specific configurations required under various scenarios, and specifies the recommended vendor, purchase mechanism, configuration, and estimated costs of the required components.
This paper focuses on deployments used to host desktop interfaces for end users. It does not address requirements for virtualization of server-based applications.
What is Virtualization?
Virtualization is the division of a single physical computing resource (i.e. a server or PC Blade) into discrete components which, during interaction with outside systems, behave like individual physical devices. These devices, resident on an individual hardware device, are known as “virtual machines, and the division and ongoing performance of such a system is known as virtualization. Depending on the technology used, virtualized hardware can emulate almost any type of device/operating system combination. Administrators often use server virtualization to allow them to replace multiple physical machines with fewer servers for better asset utilization. Delivered properly, desktop virtualization is a powerful technical concept which allows users to benefit from high performance centralized systems, while reducing the management load of administrators and almost eliminating downtime for end users.
Overview
Desktop virtualization has several required components: the centralized hardware, the host operating system, the virtualization layer, the end user computing device and the user management software. These components are deployed and function together as a complete system.

CONFIGURATION GUIDE
Component Details
A basic PC Virtualization deployment requires several discrete components:
Hardware Platform: ClearCube PC Blades are fully configurable for optimal user performance and are based on familiar PC components including Intel Pentium 4 processors, full-sized hard drives, standard memory, etc. For a four-user system ClearCube recommends Blades with 2 GB of memory for optimal performance.
Host Operating System: The host operating system runs directly on the physical computing hardware. Options for the host operating system include Microsoft Windows Server 2003, Linux (various
distributions), or a hypervisor that is built into the virtualization software (e.g. VMware ESX).
Virtualization Software: This specialized software allows administrators to create “virtual machines” that have specified behavior and characteristics. These virtual machines can be made to emulate a particular hardware device, which can then act as a platform for specific end user software.
User Operating System: This is the operating system presented through a remote connection to an end user device. This is typically Microsoft Windows XP Professional, although other operating systems (such as Linux) can also be made available to end users.
Access Device: With the Hardware Platform deployed in a central location away from the end user, some type of device is required to access the virtual machine / virtualization layer. An access device is typically an I/Port, but other devices can be used, including a tablet client, laptop, or even legacy desktop PC.

a platform for initiating and maintaining a communication session with the virtual machine. ClearCube sells I/Ports with either Microsoft Windows XP Embedded (XPe) or Linux. The essential function require of this access device OS is the ability to launch a session running Microsoft Remote Desktop Protocol (RDP), which is the protocol used to communicate back to the virtual machine.

connections between I/Ports, users and Virtual Machines. Administrators can also switch an I/Port user to a spare VM should they experience a problem. The Sentral I/Port agent presents the end-user with a login screen that automatically populates the target VM information configured in the Sentral management console. Auto discovery of I/Ports and VMs makes it easy to inventory and manage assets. In addition, an update feature deploys driver updates and new applications to I/Port groups.

Health of critical hardware components such as Blade and Chassis fans and power supplies as well as internal temperatures can be monitored to ensure uninterrupted operation of the whole system. Sentral’s powerful hardware remote control feature gives an administrator the capability to connect directly to any host Blade using ClearCube’s unique C/Port technology.

Administrators must be able to maintain full hardware and software control of the environment as users are not enabled to create and manage the virtual machines on their own.

CONFIGURATION GUIDE
Possible Adjustments from Recommended Options
These basic configurations can be adjusted depending on end user requirements. These adjustments include:
Increased Users per Blade: Depending on customer requirements, administrators may deploy more than
the standard four users per blade. With higher numbers of users per blade performance levels must be monitored to ensure customer satisfaction. Fortunately, administrators may easily reconfigure the number of users that may connect to PC blades as needed.
Conversion to non-virtualized users: For power users, 1:1 configurations allow users to customize their
PC blade with unique applications or data which is not required by other users. Unlike PC blades, servers cannot economically be presented to users in a 1:1 fashion.
