84 DOMINION KX USER G UIDEEthernet and IP NetworkingQUESTION ANSWERHow much bandwidthdoes Dominion KXrequire?Dominion KX offers integrated IP-Reach technology – the very bestvideo compression available. Raritan has received numerous technicalawards confirming its high video quality transmissions and the lowbandwidth utilization.Raritan pioneered the KVM Over IP functionality that allows users totailor their video parameters to conserve network bandwidth. Forinstance, when connecting to Dominion KX through a dial-up modemconnection, video transmissions can be scaled to grayscale – allowingyou to be fully productive while ensuring high performance.With that in mind, the following data refers to Dominion KX at itsdefault video settings – again, these settings can be tailored to yourenvironment. They can be increased to provide even higher qualityvideo (color depth), or decreased to optimize for low-speedconnections.As a general rule, a conservative estimate for bandwidth utilization (atDominion KX’s default settings) is approximately 0.5Mbit/seconds peractive KVM user (connected to and using a server), with veryoccasional spikes up to 2MBit/seconds. This is a very conservativeestimate because bandwidth utilization will typically be even lower.Bandwidth required by each video transmission depends on what task isbeing performed on the managed server. The more the screen changes,the more bandwidth is utilized. The table below summarizes some usecases and the required bandwidth utilization at Dominion KX’s defaultsettings on a 10Mbit/s network:Idle Windows Desktop 0 MbpsMove Cursor Around Desktop 0.18MbpsMove Static 400x600Window/Dialog Box0.35MbpsNavigate Start Menu 0.49MbpsScroll an Entire Page of Text 1.23MbpsRun 3D Maze Screensaver 1.55MbpsWhat is the slowestconnection (lowestbandwidth) over whichDominion KX canoperate?33Kbps or above is recommended for acceptable KX performance overa modem connection.What is the speed ofDominion KX’sEthernet interfaces?Dominion KX offers two 10/100 speed Ethernet interfaces, withconfigurable speed and duplex settings (either auto-detected ormanually set). Dominion KX does not require a gigabit Ethernetinterface because its output (see above question) would never evencome close to exceeding the 100Mbit/sec limit of 10/100 Ethernetnetworking.Can I access DominionKX over a wirelessconnection?Yes. Dominion KX not only utilizes standard Ethernet, but also usesvery conservative bandwidth with very high quality video. Thus, if youhave a wireless client with network connectivity to Dominion KX, youcan configure and manage your servers at BIOS-level wirelessly.
