PCI-RMS Bridge to RMS Bus (I or II)
Features
-
Provides a high speed data connection between Concept/32® Reflective Memory Systems and PCI-RMS Nodes (including LCRS, Linux or Windows PCs)
-
Bridges to either RMS I or RMS II Buses
-
Bridge transfer between RMS Bus ( I or II ) and PCI-RMS Ring can be controlled by configurable memory regions
-
PCI-RMS Ring transfers below 16MB/sec can be selected to pass to an RMS I Bus
-
PCI-RMS Ring transfers below 256MB/sec can be selected to pass to an RMS II Bus
-
Configurable to provide RMS Bus ( I or II ) arbitration and termination
Benefits
-
Allows connection of Legacy COMPRO Computer Systems to modern "open" computer systems using Windows NT®, UNIX Tru64, Solaris™ and/or HP's OpenVMS™.
-
Interfaces with exiting RMS Bus cables
-
No additional software required
Overview
The PCI-RMS Bridge provides a path between COMPRO’s Reflective Memory System (RMS) and the PCI-RMS Ring. The Bridge allows either RMS I or RMS II transfers to propagate to PCI-RMS Nodes and PCI-RMS Node transfers to flow onto RMS I or RMS II Bus. The Bridge provides a method for connecting Nodes to an existing RMS Bus using "state of the art" computing systems. This capability offers a seamless, non-intrusive mechanism to augment Legacy systems with powerful new features using today's computing solutions. By adding PCI-RMS nodes, the architecture can easily expand into a tightly coupled "super-system", cooperatively working on the most challenging applications.
The Bridge requires one node ID on the RMS Bus (I or II) and one node ID on the PCIRMS Ring. The following block diagram illustrates how a PCI-RMS Ring connects to a Concept RMS Bus using the RMS Bus to PCI-RMS Bridge.
Physical Description
The Bridge has a similar form factor to an RMC. During installation, an RMC is removed from the RMC Chassis and the Bridge is installed in its place. Compatible RMS Bus cable connectors are provided for connection to the RMS Bus. Two copper PCI-RMS cable connectors are provide for connection PCI-RMS Ring nodes.
