HP Integrated Lights-Out 2 - Manual (Page 95)

Use the following client and browser settings to optimize performance:
•
Display Properties
Select an option greater than 256 colors. —
— Select a greater screen resolution than the screen resolution of the remote server.
— Linux X Display Properties—On the X Preferences screen, set the font size to 12.
•
Remote Console
For Remote Console speed, HP recommends using a 700-MHz or faster client with 128
MB or more of memory. —
— For the Remote Console Java applet execution, HP recommends using a single processor
client.
•
Mouse Properties
Set the Mouse Pointer speed to the middle setting. —
— Set the Mouse Pointer Acceleration to low or disable the pointer acceleration.
Recommended server settings
The following is a list of recommended server settings based on the operating system used.
NOTE: To display the entire host server screen on the client Remote Console applet, set the
server display resolution less than or equal to that of the client.
Microsoft Windows Server 2003 settings
To optimize performance, set the server Display Properties to plain background (no wallpaper
pattern) and set the Server Mouse Properties to Disable Pointer Trails.
Red Hat Linux and SUSE Linux server settings
To optimize performance, set the server Mouse Properties>Pointer Acceleration to 1x. For KDE,
access the Control Center, select Peripherals/Mouse, then select the Advanced tab.
Text-based remote console overview
iLO and its predecessors support a true text-based remote console. Video information is obtained
from the server and the contents of the video memory are sent to the management processor,
compressed, encrypted, and forwarded to the management client application. iLO uses a
screen-frame buffer, which detects changes in text information, encrypts the changes, and sends
the characters (including screen positioning information) to text-based client applications. This
method provides compatibility with standard text-based clients, good performance, and simplicity.
However, you cannot display non-ASCII or graphical information, and screen positioning information
(displayed characters) might be sent out of order.
The Remote Console uses Virtual KVM and does not provide a true text-based console. iLO 2 uses
the video adapter DVO port to access video memory directly. This method significantly increases
iLO 2 performance. However, the digital video stream does not contain useful text data. Data
obtained from the DVO port represents graphical data (non-character-based), and is not
comprehensible ASCII or text data. This video data cannot be rendered by a text-based client
application such as Telnet or SSH.
Text-based console during POST
The standard iLO 2 text-based remote console remains available on iLO 2 until the operating system
POST is complete. iLO 2 standard firmware continues to use the virtualized serial-port functionality
of the management processor. On the iLO 2 firmware, the virtual serial port was renamed Remote
Serial Console. iLO 2 uses the Remote Serial Console to access a pre-operating system, text-based
