GE Intelligent Platforms introduces a new range of low profile reflective memory node cards designed for demanding applications such as simulation, process control and data acquisition.
Based on the low profile PCI Express platform, the PCIE-5565PIORC reflective memory node cards further extend the company’s RFM 5565 family of reflective memory solutions.
Designed for real-time applications such as simulation and training, industrial process control as well as data streaming and 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.
Such applications are characterised by the need to move and share data at fast, deterministic rates.
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.
According to Wayne McGee, Leader, Commercial Product Management at GE Intelligent Platforms, reflective memory provides a unique solution in environments where determinism, simplicity of implementation, zero software overhead and operating system independence are significant factors.
In direct contrast to technologies such as Gigabit Ethernet, Infiniband and Fibre Channel that are not designed to deliver the sheer performance required, reflective memory is designed specifically to enable the sharing of data among processors in real-time by mission-critical applications.
Key features of 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 is doubled to 512MBytes/second; larger memory of 256Mbytes is 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 10 kilometres
- Ideal solution for demanding applications due to its low latency and determinism
- Typical node-to-node propagation time using reflective memory is 1 microsecond, an advantage over other network technologies such as Ethernet that cannot achieve the same latency
