Redundant Isn’t Resilient

Redundancy is an important part of the puzzle, and the reliability of a data center relies heavily on back-up generators, on-hand replacement hardware and secondary network connections. But while redundancy is a part of the resilience solution, it is not the only consideration. In smaller locations and satellite offices, it’s not cost effective to build in redundancy. And with no technical staff on site, the ability to monitor, manage and remediate the IT infrastructure remotely is a significant addition to a resilient solution.

Smart Out-of-Band management allows the network engineering team to securely access critical devices from a central location, to anticipate and remediate issues without sending a tech to site.

Discover the networking issues that are keeping senior IT decision-makers awake at night. Read the independent research commissioned by Opengear.

Failover to Cellular

Enable always-on availability

Opengear Failover to Cellular™ (F2C) provides continued internet connectivity for remote LANs and equipment over high-speed 4G LTE or 3G networks when the primary link is unavailable. Ensuring speed to keep the network running smoothly and link diversity for true WAN resilience, Failover to Cellular is built on robust IP Passthrough technology. This allows for easy integration into existing installs or can be rapidly deployed for instant-on connectivity for new networks and branch locations.

This feature is useful for an SD-WAN deployment. SD-WAN enables organizations to reduce costs and maintain secure network connections, however the high bandwidth internet connections, routers and constant firmware updates associated with this can introduce a single point of failure. If the network goes down during a deployment, Smart OOB™ and Failover to Cellular ensures secondary access to the routers to easily reflash or power cycle. NetOps staff are able to remotely get the network backup and running without an onsite visit.

Increase resilience and remediation

Failover to Cellular allows organizations to maintain connectivity and decrease disruption with ensured business continuity. Easily integrating with existing IT systems and network infrastructure, F2C restores WAN connectivity without manual intervention. Utilized with Smart Out-of-Band  (Smart OOB), which is built into all Opengear devices, organizations are able to have remote access even when WAN and LAN networks are down. During an outage, in order to remediate the problem as quickly as possible, network engineers must have visibility of the whole network. Smart OOB provides engineers with full visibility to maximize uptime and reduce outages.


Remediate issues remotely

Distributed enterprises often times may experience disruption events that effect the primary network connection. Failover to Cellular built-in to Opengear devices, automatically activate a secondary connection to re-establish in and outbound network access. Once failover is enabled, Opengear devices are able to detect failures sending ICMP ping requests from the primary network interface to a primary and secondary probe address remotely. If these requests fail – the primary connection has been deemed as having also failed. When the primary connection has been restored, the devices automatically fail forward and resumes normal operation.


Zero Touch Provisioning (ZTP)

In hyperscale infrastructures, automation is the name of the game.

Network administrators tasked with deploying large scale IT infrastructure increasingly look to automate the deployment process.  Traditional deployments require them to log into a single unit via CLI and configure all settings – and then rinse and repeat.  This rinse and repeat model is error prone and mistakes could easily be made which could prevent out-of-band access during critical failures. By leveraging Zero Touch Provisioning (ZTP), administrators can now automate repetitive tasks, reduce human touch points, reduce errors and scale the deployment process to any size.  Customizable scripting and file types allow ZTP to be flexible in any type of environment.

Opengear’s Zero Touch Deployment

  • Cellular connectivity for Day One installations to prevent unnecessary delays
  • Shared hardware reduces deployment costs
  • Use a DHCP and file server to provision devices with configuration and firmware during initial boot
  • Built-in ZTP for rapid and automated configuration deployment
  • Adaptable for existing provisioning systems

Faster Deployment with Opengear

An Opengear customer in the media and communications industry was utilizing the standard deployment method on a new large data center with many rows of equipment. They utilized a DHCP server on a cart and ZTP to provision 4 devices at a time. The Network Admins then verified the setup and moved onto the next batch. Due to the scale of the deployment, this was inefficient and very costly with each set taking about 2 days. When they transitioned to Opengear’s solution, eliminating the need for manual setup of each individual device, the deployment time was reduced to 2 hours and with additional tweaks reduced that time to 20 minutes.

Sanity Check Your Network

Link Layer Discovery Protocol (LLDP) ensures the network is setup as it was designed. In a large and complex data center, it can be a tedious and time-consuming task to verify the installation, and an incorrect connection could cause issues down the road including network downtime and loss of revenue. LLDP will ensure the network topology is correct and that the connections between the devices are correctly installed. This automates the verification process instead of checking every port and every cable.

Network Labs

Simple Management for Complex Lab Networks

Network labs require always on connectivity, whether supporting device testing before shipment, validating firmware upgrades or developing new hardware. Housing equipment and software from a wide range of vendors along with a growing number of IoT devices, Smart Out-of-Band management provides an ease of configurability and automation for even the most complex network lab.

Device Testing

To ensure that customers receive fully functioning products, extensive testing is completed before shipment. Unrealistic for one operator to efficiently run these Devices Under Test through the QA process, advanced features of Opengear console servers remediates this issue ensuring speed and high reliability for always on access. Allowing up to 96 devices to be connected at once, programming enables it to simulate operator input through a series of standard tests. Alerts, pass/fails and input/outputs are available to the QA team for final verification. Cascading allows multiple Opengear console servers to be clustered with one unit acting as the master to thousands of serial ports. These lab networks can then test large batches of devices with minimal operator intervention which enables efficient, high density testing and leads to significant cost savings.

Remote testers can:

  • Recover from error conditions
  • Power cycle a locked up device
  • Reboot and reconfigure different versions of software

Firmware Validation

One of the most common applications for network labs is validating firmware upgrades and regression testing on various versions of operating systems. In these cases, any action or output must be logged and available for analysis – console errors, results, edge cases, random re-boots, last gasp trace and more. Opengear console servers support multiple versions of firmware with large embedded memory. There is also support for power cycling frozen test devices with preconfigured alerts while all actions and outputs are logged for analysis.

Connect to a wide range of devices with:

  • USB
  • Ethernet
  • Serial ports

Provisioning New Lab Networks

Zero Touch Provisioning allows lab network engineers to set up new devices with automation to enable quick deployment and configuration in new, multi-vendor environments. Paired with Smart Out-of-Band engineers are able to manage and monitor remote equipment. High port densities allow for a wide variety of configurations while multiple firmware updates are enabled with embedded memory.

SD-WAN and Out-Of-Band

Creating Smarter Networks

SD-WAN provides organizations with secure network connections at a lower cost. Creating more agile Wide Area Networks (WANs) that are able to support the increasingly sophisticated distribution of network devices across multiple sites, the wide range of SD-WAN benefits have made it the standard in enterprise deployments.

These benefits include:

  • Secure connection of standard broadband via a dynamic VPN tunnel
  • Increased flexibility of new networks
  • Reduced costs using commodity hardware
  • Quick deployment of new networks

To provide these benefits however, the local routers in SD-WAN deployments have become more sophisticated which can pose challenges to traditional network management which expects constant network connectivity.

Understanding Potential SD-WAN Interrupters

The new flexibility enabled by SD-WAN brings with it a heightened need for remote engineers to manage on-site devices. The sophistication of the SD-WAN hardware introduces points of failure which without the proper solutions in place, become large scale disruptions.

These points of failure include:

Updates: Every time a firmware update is executed, there is a risk of a misconfiguration or error which can bring down the router.

Security: SD-WAN needs additional security offerings to protect the enterprise. The primary SD-WAN connection must be secure, and must be added to any other security solution being deployed.

Read our SD-WAN Solutions Overview Sheet to learn more about possible points of failure.

Ensuring Network Resilience with SD-WAN

SD-WAN is not a standalone solution. During the initial rollout or migration from the previous WAN, an organization’s network can be left unstable with frequent updates and glitches. Although there are many benefits to SD-WAN deployments, single points of failure can result with potential downtime. Smart Out-of-Band supports SD-WAN deployments, allowing engineers to access the network at all times.

Smart Out-of-Band is separate to the production network, providing engineers the ability to remotely monitor and manage all remote devices so that a disruption won’t affect the primary operation. Ensuring continuity and uptime using automated intelligence, Smart Out-of-Band paired with Failover to Cellular™ enables network resilience by providing always on access. Lighthouse Enterprise provides full network visibility to diagnose and remediate the issue if disruption occurs.

NetOps Automation

NetOps for your Network

DevOps tools are increasingly applied to networking, creating a NetOps approach to building and maintaining a reliable infrastructure to support the virtualized world – a network that is both available and agile. One approach to introducing NetOps into an enterprise is to layer it into an existing solution, adding functionality and flexibility to a familiar component of your infrastructure.

A Smart Out-of-Band management network already provides presence and proximity to your critical devices, and so is well-placed to bring NetOps automation to your network. The ability to run standard NetOps tools, such as Docker, Ansible, and Python on a console server provides a new way to automate your operations at centralized and remote locations.


The OM Family of Console Servers

That solution now exists, in the new Opengear OM Family of Console Servers – Network Management appliances that combine the capabilities of a Smart OOB Console Server with the flexibility of NetOps Automation. They feature an x86 CPU to power automation tools, and a TMP2.0 chip for embedded security.

The compact OM1200 appliance is designed specifically for secure edge deployments, used in combination with Lighthouse Management Software, while the OM2200 appliance is configured for data centers and high density locations.

Integrated into Opengear’s Network Resilience Platform, they provide a separate, secure management plane which supports emerging requirements in Network Management and Automation.


Out-of-Band Management

Resilience for Your Network

Out-of-Band management’s primary application is to provide secure, remote access to your critical devices even when the primary network is down. It offers presence and proximity to your distributed network, with a console server at every location, physically connected to routers, switches and key hardware. The addition of 4G-LTE provides a secure alternative access path, and Failover to CellularTM provides enough bandwidth for critical processes to continue to operate during an outage. When the network goes down, Out-of-Band keeps you running.


For Day One, Every Day, and When the Network Goes Down

Is it smart to rely on the Production network to manage your network every day? With secure remote access to your devices via the console servers, Out-of-Band (OOB) management creates an always-on independent management plane, giving you reliable access to monitor and manage your IT infrastructure. Lock down the most critical functions on the Production network, and use the more secure OOB network to configure and manage your devices. Out-of-Band is the Network Engineer’s Network.

An investment in Out-of-Band Management is an investment that pays off every day.

  • Secure Day One provisioning is now possible, using a NetOps Console Server with embedded physical security, capable of running Docker containers and Python scripts.
  • Every Day management and monitoring of your IT infrastructure is more secure and more resilient over the independent management plane, separate from the Production network
  • Global cellular modules and centralized management software ensures access to your critical devices to fix the issue, when the primary network goes down


Resilience in the Data Center

An Edge Network as Reliable
as the Data Center

Your customers expect the same level of service, no matter where their data comes from. As computing moves closer to the edge of the network, the high uptime of a data center must be translated to small, remote locations. With no engineer on site, and with physical redundancy cost-prohibitive at each location, you need an alternative approach to resilience. Always-on access to an independent, secure management plane via a centralized software system provides a way to monitor and remediate issues at your edge locations without sending someone to site. Out-of-Band adds resilience to your network.

In an independent survey of 500 Global IT Leaders, 49% said that Network Resilience was their #1 Priority.


Ensuring scalability and speed

What is Hyperscale computing? Click here.

Hyperscale data centers allow some of the largest technology organizations in the world, like Google, Facebook and Amazon, to maintain reliability and speed.

Hyperscale refers to the architecture of a data center and its ability to scale in response to increasing demand. This involves increasing memory, storage resources and infrastructure. The goal of scaling is to not only continue to build a system, but to do it big and fast. These massive systems are constantly rolling out new features. Because of this growth providers are prioritizing connectivity and availability – for this, they need a highly reliable solution.

Detecting and remediating remotely

Hyperscale data centers house thousands of devices and although their modular design allows operators to easily add resources as needed, their sheer size creates network visibility challenges. Constantly growing, operators are running into challenges that are causing outages and downtime. An alternative path to devices located at remote sites, Smart Out-of-Band (Smart OOB™) allows hyperscale providers to maintain connectivity if this occurs. Operators are able to securely monitor and access all devices without impacting normal operations to ensure business continuity.

When an error occurs, locating the exact router that is experiencing an issue can take hours or days without the right solution. Using Smart OOB operators are able to automatically find where an error has occurred and if it can be remediated or needs to be replaced to ensure business continuity.

Automating the deployment process

Zero Touch Provisioning allows hyperscale providers deploying large scale IT infrastructure to automate the process – repetitive tasks are reduced, human touch points are decreased and errors are lessened. Customizable scripting and files allow ZTP to be flexible in any environment. It allows hyperscale providers to remove the human factor and enable mass provisioning through the rack.

Zero Touch Deployment from Opengear:

  • Ensures adaptability for existing provisioning systems
  • Prevents unnecessary delays by ensuring cellular connectivity for Day One installations
  • Verifies network topology to quickly troubleshoot and remediate issues using Link Layer Discovery Protocol (LLDP)
  • Reduces deployment costs with shared hardware

Simplifying secure deployments

The NetOps Console Server allows providers to provision new networks remotely and securely. Only requiring “smart hands” to rack, stack and cable the infrastructure, initial configuration tasks can be completed onsite, even when there is no existing WAN or LAN in place.


The next generation of wireless technology is here. 5G will enhance connectivity across all platforms, providing more efficient, faster and better signal strength which opens doors for new possibilities across cellular networks. It is predicted that by 2024 more than 1.5 billion devices will be connected to 5G.1 So how will 5G enhance your cellular connectivity?

Differentiating Between 4G and 5G

5G will be a strong enabler in the expansion of the Internet of Things (IoT), given the speed and versatility it will bring to networks. 5G has a range of benefits when compared to 4G, based on its use of the 30 GHz to 300 GHz spectrum:

  • Higher speeds: 5G peak speeds, at up to10 Gigabits/s, will potentially be ten times the speed of 4G. 2
  • Lower Latency: 5G offers latency below 1ms, compared to a typical 4G performance of 10-50ms. 2
  • Greater capacity: 5G networks will have capacity for a larger number of connected devices, by some estimates as much as one million devices per square kilometer3

5G is gradually being rolled out, so later iterations are expected to have even stronger capabilities.

It’s important to note that 5G, unlike previous iterations, is not expected to replace 4G. Many applications, such as standard mobile phone calls and low-data transactions, will still be carried on a 4G network, with 5G being applied primarily to large-compute and low-latency uses.

Given the higher frequency spectrum, 5G also requires a higher density of towers to cover a given area, meaning that rollout of 5G will initially be limited to metropolitan areas. It is also impacted more severely by physical barriers such as walls, trees, and even bad weather.

5G, IoT and the Edge

Cellular IoT use case segments
Credit: Ericsson Mobility Report, June 2019

Compute locations are moving increasingly to the edge, driven by the growth of IoT and the desire to process and prioritize data closer to the collection point. Faster connections associated with 5G will support that migration as enterprises distribute their network power between Data Centers, Cloud Computing and the Edge.

The low latency and high speed of 5G particularly suit applications such as consumer VR/AR, AI, and autonomous vehicles, with high data density and rapid response requirements, enabling faster adoption of these technologies.

5G and Out-of-Band

Users expect the same level of uptime and response from their network, regardless of where that compute is located. But the reality of edge locations is that the type of system redundancy and staffing that is typical at data centers are not feasible at each location. Reliable, always-on access to the network devices, via out-of-band management, is a critical component of that network resilience.

As levels of automation continue to increase, enterprises will also have to extend the reach of their management and monitoring tools. Opengear solutions anticipate the current and future network needs of 5G.

Opengear smart solutions provide engineers at the Network Operations Center (NOC) with the ability to reach devices located at the edge. Lighthouse ensures access and visibility remotely, during critical failures while Smart Out-of-Band provides advanced troubleshooting to remediate issues that may arise at the network’s edge. The NetOps Automation platform provides additional functionality to streamline repetitive workflows such as secure provisioning and event management.

Deciding When to Adopt

Each organization has a core IT infrastructure and line of business applications. Constantly improving technologies provide an opportunity to help them operate more efficiently. Once the right technologies have been identified, enterprises must identify the right moment to get on board to ensure meaningful results.

For 5G specifically, determining the right time to act requires understanding the most immediate use cases for it within the enterprise. The first is fixed internet connectivity. Instead of using cable, satellite or copper wires/ADSL, edge locations could potentially use 5G to get fixed internet connectivity. Because this eliminates the need for burdensome physical cables and wires, 5G may provide an easier method for deployment.

For many enterprises, it is too early to fully embrace 5G. Unless there are already specific applications that are limited by speed/latency of existing connectivity technologies, the value of deploying it will not yet be realized. Instead, the focus, for now, should be on understanding the technology at a high level and identifying the use cases that are likely to benefit the business most so that they can be prioritized when 5G becomes readily available.
