Redundant Out-of-Band Management for Oil Industry Network Applications

An effective out-of-band management solution provides support personnel with a secondary avenue for communicating with vital network elements at remote sites in the event that the primary avenue for communication is temporarily out of service. This means that even when the network is down, technicians can still communicate with remote devices via a secondary, out-of-band channel such as dial-up in order to restore network. Although this strategy serves well in most situations, there are also cases such as oil and gas industry network applications where the critical nature of the process demands a third avenue for communication. In these cases, a redundant out-of-band management solution can provide support personnel with an extra channel for communication with remote network equipment.

A typical redundant out-of-band management application might include a primary in-band via network, plus secondary and tertiary channels for use when the network is down. These secondary and tertiary channels could be a secondary network, satellite communication, cellular broadband, dial-up or any combination thereof. In oil and gas industry applications, this provides support personnel with a faster, more reliable means to deal with problems with remote network devices without the need for a physical service call to the remote installation site.

When routers, firewalls, Ethernet switches and safety and security equipment at a remote site become unresponsive, network support personnel can rely on three separate avenues to access power reboot and console port command functions at the remote site. This provides a dependable means to reboot unresponsive routers, run diagnostic routines on crashed process controllers or change configuration parameters on Ethernet switches, POE switches and other devices at the remote site without the expenses and delays associated with a truck roll.

The additional layer of reliability provided by a redundant out-of-band management solution helps to minimize downtime and avoid situations where malfunctioning devices might interfere with production, safety or security concerns.

WTI’s RSM-8R8-DE Series Console + Power Hybrids and TSM-DPE Series Console Servers both include dual Ethernet ports plus an internal modem, providing the perfect solution for redundant out-of-band communication in vital network applications in oil and gas industry applications or any other application that demands constant, reliable network communication. In addition to serving as the heart of an effective redundant out-of-band management solution, WTI Console Servers and Switched PDUs also feature state of the art security and authentication features, event monitoring, logging and alarm capabilities.
