GE Intelligent Platforms extends their RFM 5565 family of reflective memory solutions with the introduction of the PCIE-5565PIORC low profile PCI Express reflective memory node cards.

Designed for real-time applications such as simulation and training, industrial process control as well as data streaming and data acquisition, the low profile PCIE-5565PIORC reflective memory node cards will also serve a broad range of commercial, telecommunications and military/ aerospace applications that require redundancy for high availability.

A reflective memory network is a special type of shared memory system, which enables multiple, separate computers to share a common set of data. 

Reflective memory autonomously replicates the contents of one processor's memory to the memory nodes of all other network members.

New innovations in the products drive reduced implementation costs as well as training time and improve speed of data preparation while maintaining backwards compatibility with previous versions.

With the addition of Proficy SOA integration in v5.0, companies can realise reduced implementation and long-term support cost benefits for both small and large projects.

Reflective memory provides a unique solution in environments where determinism, simplicity of implementation, zero software overhead and operating system independence are significant factors.

While technologies such as Gigabit Ethernet, Infiniband and Fibre Channel are not designed to deliver the sheer performance required, reflective memory is designed specifically to enable the sharing of data among processors by mission-critical applications in real-time.

Key features of the PCI-5565PIORC reflective memory node cards: 

  • Low profile implementation, a vital requirement for many customer implementations
  • Board features 2.12 Gbaud serial connection speed, improved Programmed I/O (PIO) read performance, field upgradeable firmware and RoHS compliance
  • Maximum PCI burst rate has been doubled to 512MBytes/second with larger memory also supported
  • GE’s reflective memory networks can be scaled to 256 nodes and operated at speeds up to 174 Mbytes/second
  • Distance between nodes can be up to 10km

Reflective memory can offer an ideal solution in many demanding applications because of its low latency and determinism. Using reflective memory, the typical node-to-node propagation time is 1 microsecond.
