Supports remote authentication through third party CA certificate, RADIUS, LDAP, LDAPS, MS, and other Active Directories. Typically at least 128-bit data encryption using SSL. Dual-Power, Dual-Network, and Remote Reboot support. Designed for quick intuitive access to multiple computers. Remote Desktop has not been designed for quick access to multiple computers. Requires disconnecting and reconnecting to the Remote Desktop window. Compression - loss of screen quality and false colors. Supports SSH and Telnet, Modem (Dial-Up, Cellular), and ISDN Link. Access via Web Browser, VNC Viewer, or Serial Console. Access via Web Browser or proprietary client. In a fail-safe dual-AC system, if the primary power source becomes unavailable, the device will seamlessly source power to the secondary source without interrupting critical loads. 1ĭual input power redundancy (Dual-AC) is a critical component of any mission critical system. 2 One of the most common causes for downtime is power outages. 1 In a recent data center survey, 95% of participants said they experienced one or more unplanned outages in the past 24 months - with the average incident lasting between 86 minutes and 119 minutes. The mean cost of unplanned data center downtime is $8,851 per minute across industries. KVM switches with Dual NIC (otherwise known as Dual Ethernet) include two network input ports - if the primary network source becomes unavailable, the device will seamlessly switch to the secondary source. One of the benefits of KVM Over IP switches compared to remote access software is reliable 24/7 access to computers and servers, regardless of the state of the connected devices. Some IP KVMs such as the Raritan Dominion KX3 also offer native a multi monitor 'follow' mode, which automatically opens up all the relevant displays when connecting to a server. Multi monitor support can be achieved by using a separate port for each of attached displays, and then opening those in separate sessions - For example, a 32 port KVM would offer support for 16 devices with dual monitors. While there are some Dual-monitor IP KVM solutions are available, KVM Over IP switches also generally offer unrestricted multi monitor support for any number of monitors. Unlike with standard local KVM switches, you do not need to consider what signal your monitor supports because you will be connecting to the IP KVM through a separate PC. The main thing to consider for the type of video your KVM Over IP switch needs to support is what type of video do your servers / PCs output, and what type of video will any future servers / PCs output. Video support is dependent on the switch - some IP KVMs offer support for VGA, DVI, HDMI, and DP simultaneously, while others may only support VGA.ĭigital Video Cables: DVI-I, DVI-D, HDMI, DisplayPortĪnalog Video Cables: VGA, DVI-I, DVI-A, DisplayPort-A KVM Over IP switches can support a variety of Digital and Analog video connector types. However multiple users can still typically view and take turns controlling the same PC. Please note: Due to limitations in Win, MAC, Linux, and SUN systems, only one person can control the keyboard and mouse of an individual PC at a time. Please refer to KVM Over IP Security for more on user settings. Security settings can be set individually for each user, or globally for all the users. Multi user IP KVMs allow non-blocking access for multiple users to any of the attached devices. One of the most important questions when considering a IP KVM switch is how many users need to be able access any of the connected servers / PCs at once. We typically suggest to oversize your KVM as it is cheaper than getting a new switch. When choosing the amount of ports, it is advised to consider any future expansion plans. Please note, in some cases a device port is used for each cascaded KVM switch that is added. Some switches allow you to remote into all the chained KVMs from one designated 'master' KVM. Cascading typically requires KVMs to be from the same product family, or to be the same unit. Most IP KVMs offer the ability to expand the amount of connected devices by chaining two or more KVM switches together (known as Cascading or Daisy Chaining).
