Manufacturer-specific management only works with the servers and workstations built by that vendor. Many standard remote access control systems support a broad range of operating systems and hardware. Should the network fail, an out-of-band management system gives administrators much more control over emergencies. Out-of-band access control is a dedicated server that can be used to reboot servers, power them down, or take them out of sleep mode. Network-dependent remote access controllers work with corporate workstations and servers within the same office environment. Standard remote access controllers need the network and server machine functioning to support management, but integrated management provides a system for rebooting and managing servers during a network crisis. For example, a data center administrator might need to remotely reboot a critical server if the network fails in the middle of the night. Most environments use standard remote access controllers, but large enterprises use integrated remote access controllers for emergency support. Integration is embedded into the servers, and administrators can reboot servers and other hardware even after network failure. Because the network connection exists entirely for remote management, it’s more secure than standard remote control software where any user anywhere could attempt to access the remote machine. Integrated remote access controllers are out-of-band management platforms, meaning the controller’s network connection exists solely to support remote access and server management. What Is an Integrated Remote Access Controller? Administrators can have multiple remote control sessions open and transfer files to and from the remote server. The software sends keyboard and mouse commands to the remote machine so it appears to administrators that they’re working on their local workstation. How Does a Remote Access Controller Work?Ī remote access controller uses a client application located on the administrator’s workstation to connect to the server application located on the remote machine. Most administrators working in a large enterprise environment need remote access control to support users in different locations or servers located in a data center. Third-party software must be installed on all systems if you choose to use a different application from what is included with your operating system. No special hardware is needed for standard remote access controllers, but you need to install software or enable it if you choose to use the operating system’s embedded application. Operating systems contain remote access capabilities, but third-party software is also available. Any tool allowing for remote control of a server or a remote workstation could be considered a remote access controller. For example, Windows uses Remote Desktop Protocol (RDP) and Linux has Secure Socket Shell (SSH). Some operating systems include a remote access controller. If you plan to host a server in the cloud, chances are that you’ll need a remote access controller to configure it and install software from your workstation. Server administrators also use remote access controllers to manage servers in a data center or in the cloud. Some network administrators manage workstations across the globe, so they need a remote access controller to remotely authenticate and control a computer from their location.
