Out-of-band network management gives enterprises secure and remote access to critical network infrastructure, even during outages and service interruptions. It separates your production network from your management plane, allowing you to remotely troubleshoot, monitor, and administer your infrastructure without relying on a LAN or ISP connection.<\/span><\/p>\n Let\u2019s take a closer look at the Out-of-band network management fundamental principles, use cases, and their benefits.<\/span><\/p>\n Out-of-band (OOB) network management<\/a> provides a secure, remote connection to your network that\u2019s available during outages, breaches, and other service disruptions. It does this using a network that\u2019s specifically dedicated to infrastructure management and is completely independent of your primary network. OOB uses<\/span> serial console servers<\/span><\/a> to create an alternate path to critical network devices with a separate management plane, typically using a 4G LTE cellular connection to provide you with uninterrupted access to your network.<\/span><\/p>\n You implement out-of-band network management by deploying these serial console servers at every office, remote branch, data center, and other physical sites. By physically connecting your OOB serial consoles to critical network devices like routers, switches, and servers, you ensure engineers and administrators can always reach those devices without an IP address. That means your management plane is always available, even if your ISP connection goes down.<\/span><\/p>\n OOB network management provides higher-level remote access and control capabilities for multiple devices from one pane of glass. If your primary network experiences an outage, you can use OOB to reboot routers, troubleshoot connection problems, or perform device health checks.\u00a0<\/span><\/p>\n The best part is that you can access your out-of-band serial console servers from anywhere in the world \u2013 so your team can respond to issues at remote sites just as quickly as at your main office.<\/span><\/p>\n <\/p>\n <\/p>\n [\/et_pb_text][et_pb_image src=”https:\/\/zpesystems.com\/wp-content\/uploads\/2021\/08\/shutterstock_1936608907.jpg” alt=”shutterstock_1936608907″ title_text=”shutterstock_1936608907″ _builder_version=”4.16″ _module_preset=”default” min_height=”474.3px” custom_padding=”||0px|||” global_colors_info=”{}”][\/et_pb_image][et_pb_text _builder_version=”4.17.6″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n The ability to remotely manage your infrastructure from a dedicated network presents many business advantages. Let\u2019s examine some out-of-band network management use cases and benefits in greater detail.<\/span><\/p>\n Imagine getting a phone call at 3 a.m. because a remote site on the other side of the country has gone dark, and nobody knows why. This scenario is every network engineer\u2019s nightmare for a good reason\u2014in the past, you\u2019d have to pack a bag and hop on a plane just to get any sort of visibility on the infrastructure and what the problem might be. The cost of an outage like this, both in travel expenses and the hours of business downtime, can be devastating. For example, in a recent <\/span>Information Technology Intelligence Consulting<\/span><\/a> survey, four in ten enterprise organizations said an hour of downtime now costs their firms from $1 million to over $5 million. Now imagine how many hours it would take just to fly to your remote site to get eyes on the problem.<\/span><\/p>\n With out-of-band network management, this exact scenario is much easier to manage. As soon as your branch office goes dark, you can use your OOB management solution to connect and begin troubleshooting in a matter of minutes. Using the figure above, three hours of downtime while your technician travels to your remote site could cost up to $15 million. With OOB management, you could potentially avoid those hours of travel and downtime, saving your business a lot of money.<\/span><\/p>\n If your enterprise has many remote sites spread out over a wide geographical area, out-of-band network management can simplify remote infrastructure troubleshooting and support. Rather than hiring a technician for each region or paying to fly out your engineers every time there\u2019s an issue, your team can fully support all your remote sites from a centralized location.<\/span><\/p>\n Without any sort of unified infrastructure management, engineers must work with many different devices and interfaces. Needing to learn and configure so many systems and constantly hop from machine to machine and interface to interface increases the potential for mistakes. According to<\/span> ITIC<\/span><\/a>, misconfigurations and other human errors are the top cause of unplanned downtime, so it\u2019s critical to look for ways to simplify infrastructure management and reduce staff mistakes.<\/span><\/p>\n Out-of-band network management isn\u2019t just for outages\u2014it\u2019s a dedicated network you can use to manage all your critical infrastructure from one unified tool. OOB allows you to monitor, manage, and manipulate servers and appliances remotely. You can check event logs, monitor temperature, and even remotely control the keyboard and mouse to manage server operating systems. In addition, OOB network management consoles can automate some commands and functions, further simplifying your infrastructure management.<\/span><\/p>\n Data center admins and service providers need to manage a huge amount and variety of network infrastructure so having a unified out-of-band solution can help them realize many benefits. Using OOB to monitor and manage servers and appliances remotely, engineers can control multiple facilities from one central console, saving time and reducing the number of staff required at each location.<\/span><\/p>\n With in-band network management, all your administration and management ports are connected to the production network. If an attacker breaches your production network, they could use those ports to access more sensitive parts of your infrastructure. Plus, if your production network goes down, so does your management network. With out-of-band network management, all your administration functions are on an entirely independent network, separating user and management traffic. In the event of a breach, engineers can use their OOB console to isolate parts of the network, restrict access, and secure the management plane.<\/span><\/p>\n Another security pain point addressed by OOB network management is keeping colocation infrastructure protected while still ensuring adequate visibility. Often, physical access to colocation hardware is restricted for security purposes, so if there\u2019s an outage or breach, you may not be able to get visibility on the problem. <\/span><\/p>\n With out-of-band network management, you can remotely access and manage your colocation infrastructure even when the ISP connection is down. This allows you to fully control your hardware and remediate issues quickly without compromising facility security.<\/span><\/p>\n Network security should be on every enterprise\u2019s priority list right now. Cyberattacks are common and can be economically disastrous\u2014according to a recent<\/span> IBM study<\/span><\/a>, the average cost of a data breach is $3.86 million. Investing in an out-of-band network solution that allows you to isolate your production network from your management plane and gain visibility on physically secure devices could prevent such a breach from occurring and save you money in the long run.<\/span><\/p>\n <\/p>\n Out-of-band network management provides numerous benefits to any organization seeking to improve its remote infrastructure management capabilities. Using OOB, you can remotely troubleshoot network issues from anywhere in the world, even if the primary ISP is down. OOB solutions also simplify remote infrastructure management by providing a unified control panel to monitor, manage, and manipulate all your servers and appliances.\u00a0<\/span><\/p>\n Finally, you can improve your network security by segregating all device management from your production network while still maintaining remote and colocation hardware. All of this is possible with a unified out-of-band network management solution, like ZPE Systems\u2019 Nodegrid.<\/span><\/p>\n [\/et_pb_text][et_pb_text _builder_version=”4.17.6″ _module_preset=”default” text_text_color=”#FFFFFF” background_color=”#358AAF” custom_margin=”||||true|false” custom_padding=”30px|30px|30px|30px|true|true” global_colors_info=”{}”]<\/p>\n To learn more about how<\/b> ZPE Systems<\/b><\/a> can help you streamline your remote infrastructure management,<\/b> contact us<\/b> online or call 1-844-4ZPE-SYS.<\/b><\/p>\nOut-of-band network management fundamental principles<\/b><\/h2>\n
