Heed all of the conditions in the WARNING statement under the RACK STABILITY subsection below when moving and servicing an HP product rack and its rack-mounted hardware components.
safety and support information safety warnings power distribution units (PDUs) A Power Distribution Unit (PDU) is equipment located in or near a computer room which breaks down electric power from a high-voltage source to appropriate levels of distribution to the central processing unit and peripheral devices of a computer system. Figure 1-1 shows an example PDU that is used with the HP product racks. This example is the HP E7674A 16 Amp 100-240VAC PDU (part number A5137AZ).
safety and support information safety warnings Figure 1-2 Cable and Plugs Between the PDU and the Wall Receptacle IEC309 L6-20P L6-30P IEC-320-C19 CEE7/7 Unterminated PDU leakage current WARNING 16 Due to the number of components that can be installed on one Power Distribution Unit (PDU), there may be a risk of high leakage current (>3.5mA). Reliable ground circuit continuity is vital for safe operation of such components.
safety and support information safety warnings PDU power limitations To reduce the risk of overload, do not exceed the rated load of any single PDU. In addition, do not load a single NEMA 5-15 (see Fig. 1-3) receptacle with more than 15 Amperes and any single IEC 320-1/C13 receptacle with more than 10 Amperes. In general, make sure that the power source circuits are able to safely provide the current that will be required by all components drawing power from them.
safety and support information safety warnings Although this problem is relatively rare, it may be an issue within your computer room. Since metallic contamination can cause permanent or intermittent failures on your electronic equipment, Hewlett-Packard strongly recommends that your site be evaluated for metallic particulate contamination before installation of electronic equipment.

installation and user information document purpose document purpose The purpose of this document is to provide information on installing, customizing and using hp visualization center sv6 systems. Because the workstations will arrive racked, pre-cabled and pre-configured, minimal information about hardware setup is included in this document. Sections of this document provide steps for setting up and configuring systems.
installation and user information document purpose Chapter 2 • Software Set-Up Specifications - Reference for the software that was pre-loaded on your system. • Updating Software - Explains how and when to do software and firmware updates. Keeping your graphics patches updated is essential for taking full advantage of this new technology. • Advanced Set-Up for Multiple Channels - Gives an overview of how to use multiple hp visualization center sv6 clusters to output across multiple display devices.
installation and user information product overview product overview The hp visualization center sv6 solution is a system developed to meet your visualization performance and image quality needs. The key attributes that make this system unique from existing scalable solutions include: • scalable rendering performance, image quality and resolution, • resources can be dynamically switched between performance and image quality, • use of standard SPU and graphics components.
installation and user information product overview Figure 2-1 hp visualization centers sv6 (j6700) and mini-sv6 (b2600) The hp visualization center sv6 is: • A scalable solution for OpenGL display list-based applications that provides geometry acceleration of aliased rendering that is greater than stand-alone hp workstation performance. • A solution that offers increased visual quality via anti-aliasing at stand-alone hp workstation performance rates, or better.
installation and user information product overview visualization center hp visualization center sv6 cluster is made up of one 2D master node and a supported number of 3D slave nodes. The 2D node is responsible for rendering the GUI and X11 rendering primitives. The 3D slave nodes, also called “pipes,” are responsible for rendering all or some part of the 3D scene. The video output from each node is then combined, or composited, to a single monitor.
installation and user information product overview Figure 2-2 16-pipe system configuration NOTE Arrangement of the hardware in the racks may vary. The 2D master system controls the rendering that happens on the 3D pipes. The output of each pipe is then fed into hardware called the Digital Compositor. The Compositor combines the inputs into a single output stream to the display. A local high-speed Gigabit Ethernet switch (hp ProCurve Switch) which connects the systems.
installation and user information product overview This driver communicates with the EtherLite-32 and makes the Digi switch’s serial connections appear as though they were direct serial connections to the master system. Thus, the master node communicates with the slave node via a serial port communications program, such as cu on HP-UX or the dinc program supplied with the Digi switch.
installation and user information product overview Figure 2-4 Multiple Display Channels For multiple displays (up to three displays) additional hp visualization center sv6 clusters can be added to increase screen real-estate. “Screen real estate” describes the expanded workspace created by spreading one continuous screen across several display devices.
installation and user information product overview hp visualization center sv6 architecture This section discusses a general overview of how the hardware is used by the hp visualization center sv6 architecture, using a 16-pipe system as an example: Figure 2-5 16-pipe System Architecture The 16-pipe system contains 16 hp workstations j6000 (A5990A) or j6700 (A7278A) which perform the 3D rendering. Each of these machines contain the hp fx10 Graphics Accelerator Card (A1299B).
installation and user information product overview The 17th hp workstation fulfills three roles: 1. Application Server: This is the machine on which the application runs. Graphics protocol based on OpenGL is sent to the 16 3D systems via high-speed Gigabit networking. 2. Xserver: In addition to running the application, this machine also renders the 2D X window system and responds to the keyboard and mouse. 3.
installation and user information product overview NOTE Each fraction of the screen is called a “screen rectangle.” Example: In a configuration with five workstations (one doing 2D rendering and four doing 3D rendering), each 3D workstation would output one of the four screen rectangle areas on the display. You can specify how the screen is dissected. The basic options are grid, vertical slice, horizontal slice and pane. See the /opt/graphics/OpenGL/sv/doc/README.setpipes file for more details.
installation and user information product overview Figure 2-8 Mixed Mode For example, with a 16-pipe hp visualization center sv6, each of the quadrants pictured above could be accumulated by N graphics-enabled workstations (N is equal to the number of samples to be jittered). If N=4, then you get four samples for accumulation on each section and since the screen has been split into four sections, you also get improved acceleration. To increase the rendering performance, use the Accelerate Mode.
installation and user information product overview Figure 2-9 Mixed Mode 16-Pipe Example supported configurations Each channel is driven by a set of workstations assigned to do 3D rendering (3D pipes) plus one to do 2D rendering (2D pipe). This table shows the hardware combinations that are supported.

To put it back to its original setting: unset HPOGL_DSM_DISABLE_FAST_ZOOM The environment variable HPOGL_OPT_CACHE_MATRICES can be used with any application, but has the most impact on applications that benefit from matrix caching.
installation and user information optimization glEnable(GL_SUPERSAMPLE_HP); glDisable(GL_SUPERSAMPLE_HP); CAUTION Depending upon application frame rates and window size, enabling scene anti-aliasing can impact performance significantly. With low frame rates and/or small windows, the performance impact is minor (5% or less). Also, when scene anti-aliasing is turned on, there is much less fx10 memory available for caching texture maps, so this can also impact rendering performance.
installation and user information optimization WARNING Do not add this environment variable to /etc/X11/X0screens. That would disable all scaling for everything rendered to the screen. By applying it only to the desired application, you can leave scaling enabled for everything else not inside the immediate mode application’s windows. In short, you should never set this variable so that it is applied to your user or system environment.
installation and user information optimization gamma value Another way to fine-tune the image quality is to adjust the gamma correction. Specify the default values to be used for 3D gamma correction. using the instructions in the /opt/graphics/OpenGL/sv/doc/README.gamma file. HPOGL_PUSH _ENVIRONMENT To override the default environment specified in the SlaveEnvironment section of the /etc/X11/X0screens file, have the application startup script set HPOGL_PUSH_ENVIRONMENT.

hp scalable visualization digital compositor compositor self-test sequence compositor self-test sequence introduction All compositor cards are assumed to be fully functional before they are installed in a compositor chassis. They are all individually and functionally tested at the manufacturer. Once they are installed in the compositor backplane, however, they could fail by not being seated properly or by having bent bus pins.

If the value does not match, two failing cards are identified, the one driving the test value and the one receiving the test value, as it is impossible to determine which of the two cards has the failing bus connection. testing output or input cards The test can have two results. One is success. The other is failure, along with a list of one or more cards that failed.

glossary accelerate mode - In this hp visualization center sv6 operating mode, each pipe renders only a fraction of the screen, thus speeding up rendering performance. accumulate mode - In this hp visualization center sv6 operating mode, image quality is improved. Each pipe generates the complete scene, jittered by sub-pixel values. These jittered images are then averaged together to get a better quality image.
glossary active stereo referred to as the anti-aliasing mode. The more graphics-enabled workstations you add, the more samples can be taken, and the better the image quality gets. active stereo - Standard stereo capability where glasses/emitter switch back and forth between the left and right eye to make an image appear to have depth on the z-axis of the screen. CAT 5 cable - Regular twisted pair LAN cable.
glossary screen master mode - This is the workstation where the master X server is run to control all other rendering via the workstations assigned to do 3D rendering (slave nodes). This system also does all of the 2D rendering for the entire screen. mixed mode - In this hp visualization center sv6 operating mode, the screen is divided among the 3D slaves for accelerate mode, but multiple workstations are assigned to render each subdivision for accumulate mode.
glossary screen real estate screen real estate - Describes the entire continuous screen space which can span multiple display devices. screen rectangle - A sub-division of the entire display. Each of the areas receives output from the group of 3D pipes assigned to render to it. Select a layout using /opt/graphics/OpenGL/sv/bin/setpipes or the GUI-based versions xsetpipes and xadvsetpipes. Also known as pipe rectangle. slave - 3D rendering node.
