  3. 3. The name of the original research project is RAIN which stand’s for Reliable Array of Independent Nodes. The RAIN technology originated in a research project at the California Institute of Technology (Caltech),in collaboration with NASA’s Jet Propulsion Laboratory and the Defense Advanced Research Projects Agency (DARPA). I. A component that stores data across distributed processors and retrieves it even if some of the processors fail. II. A communications component that creates a redundant network between multiple processors and supports a single, uniform way of connecting to any of the processors. III. A computing component that automatically recovers and restarts applications if a processor fails RAIN Technology
  4. 4. I. RAIN Technology is able to offer the solution by minimizing number of nodes in the chain connecting the client and server. II. RAIN Technology making the exiting nodes more robust and independent of each other. III. RAIN Technology provides the feature of replacing a faulty node by a healthy one. RAIN Technology

  6. 6.      Reliable transport? Consistent global state sharing? protocol? Always-On-IP? Local and Global Fault Monitors? Secure and Central Management?
  7. 7. 1. It includes scalability and high availability. 2. Many novel features in an attempt to deal with faults in nodes, network, and data storage, Fault tolerant interconnect. 3. Group members 4. Data storage RAIN Technology
  8. 8. Scalability Scalability is the ability of a system to provide throughput in proportion to, and limited only by, available hardware resources. A scalable system is one that can handle increasing numbers of requests without adversely affecting response time and throughput.
  9. 9. High Availability The availability of a system or any component in that system is defined by the percentage of time that it works normally. The formula for determining the availability for a system is: Availability = average time to failure (ATTF) / [average time to failure (ATTF) + average time to recover (ATTR)]
  10. 10. Data Storage Fault tolerance in data storage across many disks is obtained using redundant storage schemes. Novel error-correcting codes have been developed for this purpose. These are array codes that encode and decode using simple XOR operations. RAIN Technology
  11. 11. Fault Tolerance The ability of a system to respond gracefully to an unexpected hardware or software failure. There are many levels of fault tolerance, the lowest being the ability to continue operation in the event of a power failure
  12. 12. I. There is no limit on the size of a RAIN cluster. II. There is no concept of master-slave relation. III. A RAIN cluster can tolerate multiple node failure. IV. This is highly efficiency in traffic management. V. New node can be added into the cluster to participate in load sharing. VI. It work with many different intermit application RAIN Technology
  13. 13.      Rain technology suffers with some drawback as specified below: 1. As the rain technology requires placement of switches in between of structure, so it becomes little expensive. 2. Secondly, Installation and configuration is time consuming and requires maintenance also. 3. Although if the node of the topology fails, it will not disturb the topology completely as mentioned above but if the switch fails, it affects the network partially and switch has to be repaired as early as possible.

  15. 15.  Development of API’s for using the various building blocks.  The implementation of a real distributed file system using the partitioning scheme developed here.  The group communication protocols are being extended to address more challenging scenarios. RAIN Technology
  16. 16. The goal of the RAIN project has been to build a test-bed for various building blocks that address fault management Communication and storage in a distributed environment. The creation of such building blocks is important for the development of a fully functional distributed computing system.
