Out-of-Band Management

This blog is the first in a series that looks at the challenges and options for Out-of-Band Management (OOBM). The goal of this blog series is to: 1) help IT managers keep up with the latest changes and options for OOBM, 2) discuss when, why and how to use each OBM option, 3) review the most pragmatic approaches for the various OOBM uses cases, and 4) how OOBM networks are deployed in production data centers and remote or branch office environments.

Every IT manager knows that at some point, IT equipment will be offline and need a way to be brought back online. Outages are a fact of life in the world of IT infrastructure: some are planned, some are not, and sometimes Mother Nature just decides to give us a test.

According to the Ponemon Institute, 91% of IT infrastructures experience some level of unexpected outage.[1] Unplanned downtime is expensive in terms of revenue lost, customer dissatisfaction, and repair costs.

What is Out-of-Band Management and Why Should the IT Admin Care About It?

The simplest definition is that OOBM provides access and control of IT assets outside of the production network.[2] In most cases, this production network is based on Ethernet, but it could also include devices using InfiniBand and fibre channel.

As the name would imply, the primary use of OOBM is access and control of IT infrastructure when the production network is unavailable, such as cases involving unplanned downtime. OOBM networks can be 100% dedicated or leveraged hybrid models. The type of assets that require OOBM can include the mission critical routers, switches, KVMs, servers, storage, and appliances that serve as the backbone of the IT infrastructure.

Where and When do you need Out-of-Band Management?IT_Downtime_Unaffordable

OOBM is a core capability that every data center and remote site should have to improve overall performance, support upgrades and local network repairs, and reduce response times for outages. However, not every IT asset needs to have OOBM management. So when you are planning your OOBM requirements, you need to consider the following questions:

  1. What equipment requires 24/7 visibility and access?
  2. What and how many OOBM connectivity options (local and remote) do I require?
  3. How can I use OOBM to reduce or avoid sending staff to remote sites?
  4. What type of security does my remote management solution require?
  5. What type of logging and analysis data do I require?
  6. Do I need to provide disaster recovery support via remote management?
  7. Does the device on the OOBM network require a CLI (command line interface) or a GUI (graphical user interface)?
  8. How can I scale and expand my OOBM management solution in the future?
  9. Do I need the bandwidth to upload data, firmware, or other software?

Just as not all OOBM requirements are the same, neither are all OOBM solutions the same. In Part 2 of this series, I will discuss how OOBM is deployed in various environments.

Access infrastructure during network outages

Out-of-Band (OOB) management provides an alternative path to devices located at remote sites when the primary network is down. Separate to the production network, this allows administrators to securely monitor, access and manage all devices without impacting normal operations. Able to integrate seamlessly with existing IT network and management systems, it minimizes disruptions with an always-on connection.

To ensure even more continuity and uptime for mission-critical applications, organizations are utilizing the automated intelligence of Smart Out-of-Band (Smart OOB™).

Provide the needed assurance of uptime

Architected to exceed the demands of IT and IoT resilience, highly scalable Smart OOB is able to manage the infrastructure of hundreds of sites and thousands of devices. It protects business continuity at the hardware layer. This approach enables advanced capabilities for automatic responses and repair allowing organizations to detect faults before they become failures. Advanced troubleshooting and remediation at the network’s edge allowing organizations to reduce operating costs and minimize downtime, all from one centralized console.

So what makes Opengear’s Out-of-Band so Smart? It can:

  • Detect and remediate issues automatically
  • Operate independently from in-band network
  • Send automated alerts via email or SMS to notify of any network issues
  • Identify any inconsistencies or unusual activity with temperature conditions, cage door positions and network availability

Smart ROI with Smart OOB


Case Study: Secura Cloud Hosting

Smart OOB allows organizations across the globe to ensure resilient backup connectivity, seamlessly access devices in remote data centers and reduce costs. Opengear’s console servers and infrastructure management solutions provide resilience and dependability to improve management functions.

Learn how cloud provider Secura Hosting utilized Smart OOB to reduce the time-consuming nature of dispatching engineers to its data center sites to make configuration changes and troubleshoot issues. Having deployed Smart Out-of-Band by Opengear, they’ve improved their management capabilities which led to a return on investment in just seven months.
