Appendix A – Understanding WS460c Graphics Server Blade video modes

The WS460c Graphics Server Blade has an embedded graphics card as well as add-in high-end graphics card options. In
Gen8 or Gen9 WS460c blades, the embedded graphics chip is a Matrox G200. In earlier Gen6 blades, it was an ATI RN-50.
Depending on the configuration, it may be necessary to disable the embedded graphics so that the add-in graphics card
can run as primary without any conflicts. The WS460c has specific BIOS modes that control which graphics cards are
enabled and seen by the operating system. During system setup, all cards should be enabled (“Setup Mode”) and the
system is accessed from the iLO remote console or front dongle SUV connection. Once setup is complete, the embedded
controller is disabled and the system is booted to production mode where only the add-in card is enabled and primary
(“User Mode”). In this state, the system can only be accessed via a remoting protocol such as HP RGS, PCoIP (Horizon
View), or HDX 3D pro (Citrix XenDesktop).

WS460c G6 and Gen8 Graphics Server Blade graphics modes

User mode

In this mode, the add-in card is enabled and the embedded is disabled. The OS only sees the add-in card.

This mode is used when the installed operating system does not support using two different graphics
architectures, such as a Microsoft Server 2008 or Windows 7.

For a Gen8 WS460c, this is the primary production mode when the following operating systems are installed:
o
Microsoft Windows 7 or 8.1
o
Linux on bare metal
o
Windows Server 2008 running RemoteFX or XenApp.

In this mode, the iLO remote console and front SUV console are available during the POST, but when control is
passed to the OS, the console becomes inaccessible because the server uses the embedded video card to
generate video to the iLO/SUV console. In this mode the server console will show a message indicating it is in
User Mode:


In this mode, once the operating system is booted, the system can only be accessed via a remote protocol.

Setup mode

This mode enables all video cards but the add-in card is secondary and the embedded is primary.

This mode is used in the following configurations:
o
Full-production mode when the installed operating system supports using two different graphics
