Upgraded Database Management System Targets Carrier-Grade Networks

Version 7.0 of the Polyhedra relational database management system (RDBMS) from Enea provides a number of significant enhancements that make it ideal for carrier-grade network infrastructure systems, particularly those using distributed applications and data spread across multiple processors, blades, and operating systems. The system enhances multiprocessor performance by supporting parallel execution of queries and transactions. It increases reliability by handling memory exhaustion in a more resilient manner. And its strict version control allows field upgradeability, enabling repairs and new functionality to be added to live systems with zero downtime.

Polyhedra is a fault-tolerant, in-memory, transactional RDBMS. Available in 32-bit and 64-bit versions, it provides a secure high-performance data repository for network infrastructure applications. The system's ability to execute out of local RAM enables it to deliver orders of magnitude better performance than conventional disk-based solutions. Additionally, Polyhedra features journaling and fault-tolerant mechanisms such as instant failover and fast reconnection that ensure data persistence and enhance system availability.

The RDBMS uses a client-server architecture that enhances performance and simplifies distributed application design, particularly for systems employing heterogeneous hardware. The client-server architecture also improves data integrity and resilience by separating the data from the applications that use it, thereby protecting the memory used by the database software from accidental modification.

Polyhedra 7.0 is available immediately for a range of operating systems, including OSE, VxWorks, Integrity, Linux, Windows, and Unix. A single-user developer license costs $11,995. For more information, go to www.enea.com.
