They typically connect to infrastructure devices via serial ports (hence their alternate names, serial consoles<\/a>, console servers, serial console routers, or serial switches). IT teams use terminal servers to consolidate remote device management and create an out-of-band (OOB) control plane for remote network infrastructure. Terminal servers offer several benefits over other remote management solutions, such as better performance, resilience, and security. This guide answers all your questions about terminal servers, discussing their uses and benefits before describing what to look for in the best terminal server solution.

      What is a terminal server?<\/h2>\n

      A terminal server is a networking device used to manage other equipment. It directly connects to servers, switches, routers, and other equipment using management ports, which are typically (but not always) serial ports. Network administrators remotely access the terminal server and use it to manage all connected devices in the data center rack or branch where it\u2019s installed.<\/p>\n

      What are the uses for terminal servers?<\/h2>\n

      Network teams use terminal servers for two primary functions: remote infrastructure management consolidation and out-of-band management.<\/p>\n

        \n
      1. Terminal servers unify management for all connected devices, so administrators don\u2019t need to log in to each separate solution individually. Terminal servers save significant time and effort, which reduces the risk of fatigue and human error that could take down the network.<\/li>\n
      2. Terminal servers provide remote out-of-band (OOB) management<\/a>, creating a separate, isolated network dedicated to infrastructure management and troubleshooting. OOB allows administrators to troubleshoot and recover remote infrastructure during equipment failures, network outages, and ransomware attacks.<\/li>\n<\/ol>\n

        Learn more about using OOB terminal servers to recover from ransomware attacks by reading How to Build an Isolated Recovery Environment (IRE)<\/a>.<\/p>\n

        What are the benefits of terminal servers?<\/h2>\n

        There are other ways to gain remote OOB management access to remote infrastructure, such as using Intel NUC jump boxes<\/a>. Despite this, terminal servers are the better option for OOB management because they offer benefits including:<\/p>\n

        <\/p>\n

        Even with a jump box, administrators typically must access the CLI of each infrastructure solution individually. Each jump box is also separately managed and accessed. A terminal server provides a single management platform to access and control all connected devices. That management platform works across all terminal servers from the same vendor, allowing teams to monitor and manage infrastructure across all remote sites from a single portal.\u00a0<\/span><\/pee><\/td>\n

        <\/p>\n

        		When a jump box crashes or loses network access, there\u2019s usually no way to recover it remotely, necessitating costly and time-consuming truck rolls before diagnostics can even begin. Terminal servers use OOB connection options like 5G\/4G LTE to ensure continuous access to remote infrastructure even during major network outages. Out-of-band management gives remote teams a lifeline to troubleshoot, rebuild, and recover infrastructure fast.<\/span><\/pee><\/td>\n

        <\/p>\n

        Network and infrastructure management workflows can use a lot of bandwidth, especially when organizations use automation tools and orchestration platforms, potentially impacting end-user performance. Terminal servers create a dedicated OOB control plane where teams can execute as many resource-intensive automation workflows as needed without taking bandwidth away from production applications and users.\u00a0<\/span><\/pee><\/td>\n

        <\/p>\n

        		Jump boxes often lack the security features and oversight of other enterprise network resources, which makes them vulnerable to exploitation by malicious actors. Terminal servers are secured by onboard hardware Roots of Trust (e.g., TPM), receive patches from the vendor like other enterprise-grade solutions, and can be onboarded with cybersecurity monitoring tools and Zero Trust security policies to defend the management network.\u00a0<\/span><\/pee><\/td>\n

        Examples of terminal servers<\/h2>\n

        Examples of popular terminal server solutions include the Opengear CM8100<\/a>, the Avocent ACS8000<\/a>, and the Nodegrid Serial Console Plus<\/a>. The Opengear and Avocent solutions are second-generation, or Gen 2, terminal servers, which means they provide some automation support but suffer from vendor lock-in. The Nodegrid solution is the only Gen 3 terminal server<\/a>, offering unlimited integration support for 3rd-party automation, security, SD-WAN, and more.<\/p>\n
