KVM performance over a network When users access the HP IP Console Switch through a remote KVM console, the performance and bandwidth utilization will vary depending on several factors: • Type of connection (LAN or Internet) • Network utilization (size of a system and whether it is a dedicated management network or does double duty with main LAN) • Type and amount of hardware used for switching and routing • Video resolution and color depth • Number of screen refreshes required A remote KVM session requires minimum bandwidth since only screen changes, mouse movement, and keystrokes are transferred. However, because it is difficult to accurately predict KVM performance over a network, HP recommends that administrators do the following for KVM sessions: • Use a 100 Mbps (or faster) network. The latest HP IP Console Switches support operation on gigabit Ethernet networks. • Use standard video settings and color depth (1024 x 768 @ 256 colors). • Minimize screen refreshes by not running applications that display large windows and require frequent content changes or have significant dynamic information flowing in them. Session types Figure 9 shows an image of the HP IP Console Viewer 3.0 display when properly configured for use with an HP ProLiant server and EMS. As indicated by the arrows, three types of sessions-a KVM, iLO, and serial session-can be launched simultaneously to the selected server. Figure 9.
