Enea recently announced element, its new high-availability middleware solution for telecom, automotive, industrial control and medical instrumentation applications. According to Terry Pearson, VP of product management for Element at Enea, the release of Element represents a fundamental shift in middleware development, from an inefficient, proprietary in-house model, to a cost-effective, commercial off-the-shelf model. "Element makes it easy for OEMs to outsource their HA middleware, slashing development time and cost, and freeing up precious engineering resources for more profitable value-added tasks such as application and service development," Pearson said.

Element provides a set of services that sit between the OS and applications. It provides core services for synchronizing, instrumenting, monitoring and establishing communications between applications spread across multiple OSes and processors. It also provides network supervision, fault, shelf and upgrade management services that make it easy to monitor, repair, configure/provision and upgrade live systems as they operate in the field.

The press release states that Element is the first HA middleware solution optimized for distributed embedded systems. Element provides an end-to-end solution that makes it easy for OEMs to combine Linux with real-time operating systems (RTOS) like Enea's OSET in the same system. Element is also the first HA middleware equipped to run on DSPs and network processors as well as 32-bit CPUs, added the company.

Element's LINK communications subsystem provides the foundation for building complex distributed applications that span multiple devices and OSes. LINK services make it easy for processes to discover other processes and services, communicate with those processes, advertise service availability, broadcast information to and share information with other processes (publish/subscribe), and monitor other processes for readiness. LINK communications are device and OS independent, providing transparency that enables systems to be scaled and reconfigured without changes to the application code.

Element's HA Framework (HAF) delivers all the services required to build a true non-stop computing platform. The HAF provides full fault management, including monitoring, detection, recovery and reporting, for every resource in the system. It also employs active heartbeat monitoring and reactive error detection schemes to ensure the health of key hardware and software components at the system, slot and application levels. The HAF also performs in-service upgrades for hardware and software components with minimal disruption to the operational state of the system.

Element provides a comprehensive suite of shelf management services for configuring and monitoring individual slots, blades and chassis. Element works with shelf management controllers to detect and configure blades, track revision numbers, and monitor key blade-level parameters like temperature, voltage and fan speed. Element also supports hot swap, which enables individual blades to be inserted and removed from a live chassis.

Element is immediately available for Enea's memory-protected OSE RTOS. Element for Linux is currently undergoing beta trials with selected customers and will be generally available in Q1 2006. Pricing ranges from $75,000 to $600,000, depending on the base configuration.
