pATLAS Clusters


pATLAS architecture allows an easy clustering of multiple pATLAS units into a larger system, which we address as pATLAS Cluster.  pATLAS clustering overcomes existing processing and capacity limits of individual units making the cluster configurations suitable for specific implementations.  A cluster approach relies on the fast data exchange between individual pATLAS participants (cluster members), making the overall cluster to behave as an equivalent large process control system.





This is a scenario where three pATLAS units are doing their respective local jobs autonomously, but in full coordination with the larger and more powerful RTU system ATLAS-MAX/RTL.  They exchange needed data via FO Hub configured for master/ slave communication that is mastered by ATLAS-MAX/RTL.  The use of fiber-optics guaranties reliable and robust data exchange in harsh and hostile EMI environment, better than over any other media.  Furthermore, the additional data processing and communication with supervising remote center (in this example via a modem) are provided by ATLAS-MAX/RTL, what is very beneficial for pATLAS units themselves.. 






This is a TCP/IP/Ethernet upgraded pATLAS cluster. - three cluster members communicate through the fast underlying local master/slave multi-channel FO network, sharing all needed information, process and control data.  The role of the master module in this communication is dedicated to the Ethernet module, which is also a TCP/IP gate toward external world, here symbolically identified as a TCP/IP cloud.  The term “TCP/IP Cloud” could identify a TCP/IP compatible network of any type: local area network - LAN, wide area network – WAN, up to the global Internet network.

TCP/IP Based Clustering

Clustering could vary in size and details and it is hard to pretend to cover everything with few examples.  There are many ways to cluster existing pATLAS equipment.  The most common clustering approach is presented hereabove, although it also ofers many cluster variations.  This is a clustering of pATLAS units around the local TCP/IP network.  In this example the presented "TCP/IP Cloud" identifies the fast local area network (LAN), which enables fast data exchange between individual cluster members and with other TCP/IP compatible equipment (including modems for communication with remote control centers).
