2 Blade workstation video subsystem This chapter describes the blade workstation video subsystem. Because the blade workstation contains two types of video controllers, it is important to understand their functionality and operating modes. The two types of video controllers are: • ATI RN50 video controller ("ATI video controller")-The ATI Video controller is built-into the blade workstation. • NVIDIA Quadro FX graphics adapter ("NVIDIA graphics adapter")-The xw460c blade workstation supports a number of NVIDIA graphics adapters, either in single-card configurations or dual-card configurations. See the document Hardware and Software Supported by HP ProLiant Blade Workstations for a description of the NVIDIA graphics adapters supported by the xw460c blade workstation, as well as whether they are supported in single-card or dual-card configurations. The xw2x220c blade workstation supports only a single type of NVIDIA graphics adapter; again, see the document Hardware and Software Supported by HP ProLiant Blade Workstations for a description of the NVIDIA graphics adapter supported by the xw2x220c blade workstation In September 2008, HP began offering the HP Graphics Expansion Blade ("expansion blade"), which attaches to the xw460c blade workstation only. The expansion blade supports the installation of certain PCI-Express NVIDIA Quadro FX graphics adapters. Again, see Hardware and Software Supported by HP ProLiant Blade Workstations for a description of the PCI-Express NVIDIA graphics adapters that can be installed in the expansion blade (as well as the NVIDIA graphics adapters that can be installed internal to the blade workstation). Note that the expansion blade does not currently support dual graphics-that is, only one PCI-Express graphics adapter can be installed in the expansion blade. NOTE: NVIDIA graphics adapters are installed internal to the xw460c blade workstation if an expansion blade is not attached to the blade workstation. If an expansion blade is attached, graphics adapters can only be installed in the expansion blade, not internal to the blade workstation. Unless otherwise noted, no distinction is made in this chapter based on where the graphics adapter(s) are installed-internal to the xw460c blade workstation or in the expansion blade-because their installation location is invisible to Windows. Figure 2-1 shows the blade workstation video subsystem architecture, and lists the three operating modes.
