GoAhead has updated its Linux-oriented high availability (HA), systems management, and distributed messaging middleware. SelfReliant 3.1.1 is easier to use, performs better, and offers new tools, the company says. Additionally, it is the first HA middleware to support the SA Forum's (Service Availability Forum's) HPI B (hardware platform interface B) specification.

A previous version of SelfReliant was the first HA middleware to support the SA Forum's initial HPI specification, GoAhead claimed in August, 2003. The company first shipped its HA middleware for Linux in 2000, and has since partnered with MontaVista and other Linux and telecom software and equipment providers.

The new SelfReliant version is said to come with tutorials, and to include a variety of ease-of-use features, a management instrument interface that provides read and write access of HPI sensor and control data, and expanded Basic Availability Management heartbeat options. The latest version also provides a number of performance enhancements in the areas of database performance, database replication throttling, configuration of virtual IP addresses, Native POSIX Thread Library support, and IA-64 support. New development tools include a system model import/export tool and an added Availability Management Service transaction queue trace function, according to GoAhead.

Additionally, the software's HPI B support simplifies the use of the interface, adds several powerful new features, and adds the ability to support AdvancedTCA-based systems, and static and Dynamic Provisioning is selectable at run-time, to help detect equipment failures and configuration errors

Manfred Reitenspiess, President of the Service Availability Forum, said, “GoAhead's early implementation of the HPI B release positions SelfReliant as one of the strongest commercial off-the-shelf middleware offerings.”

Intel's GM of modular platforms, Anthony Ambrose, said, “The success of AdvancedTCA solutions is built from interoperable, carrier grade, high-performance off-the-shelf building blocks including Intel processors and GoAhead's SelfReliant HA middleware.”
