APPENDIX B: F REQUENTLY ASKED Q UESTIONS 55Ethernet NetworkingQ UESTION A NSWERHow much bandwidth doesDominion KX require?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 – allowing youto be fully productive while ensuring high performance.With that in mind, the following data refers to Dominion KX at its defaultvideo settings – again, these settings can be tailored to your environment.They can be increased to provide even higher quality video (color depth),or decreased to optimize for low-speed connections.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 very occasionalspikes up to 2MBit/seconds. This is a very conservative estimate becausebandwidth 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, themore bandwidth is utilized. The table below summarizes some use casesand the required bandwidth utilization at Dominion KX’s default settingson a 10Mbit/s network:Idle Windows Desktop 0 Mbit/sMove Cursor Around Desktop 0.18Mbit/sMove Static 400x600Window/Dialog Box0.35Mbit/sNavigate Start Menu 0.49Mbit/sScroll an Entire Page of Text 1.23Mbit/sRun 3D Maze Screensaver 1.55Mbit/sWhat is the slowestconnection (lowestbandwidth) over whichDominion KX can operate?The slowest connection is 20kbits per second (a slow dial-up modem).What is the speed ofDominion KX’s Ethernetinterfaces?Dominion KX offers two 10/100 speed Ethernet interfaces, withconfigurable speed and duplex settings (either auto-detected or manuallyset). Dominion KX does not require a gigabit Ethernet interface becauseits output (see above question) would never even come close to exceedingthe 100Mbit/sec limit of 10/100 Ethernet networking.Can I access Dominion KXover a wirelessconnection?Yes. Dominion KX not only utilizes standard Ethernet, but also uses veryconservative bandwidth with very high quality video. Thus, if you have awireless client with network connectivity to Dominion KX, you canconfigure and manage your servers at BIOS-level wirelessly.Can Dominion KX usedover the WAN (Internet),or just over the corporateLAN?Yes. Whether via a fast corporate LAN, the less predictable WAN(Internet), a cable modem, or dial-up modem, Dominion KX’s KVMOver IP technology can accommodate your connection. Raritan’s IP-Reach KVM Over IP technology is integrated into every Dominion KXunit. Raritan pioneered configurable video compression technology,leading the industry by years, as evidenced by its awards.
