REPLICA SERVER SYSTEMS AND METHODS

摘要

An adaptable replica server system includes a primary replica associated with a primary storage for storing information and a primary processor, and a secondary replica associated with a secondary storage and a secondary processor for creating confirmation data upon receiving input data from the primary replica. The replica server system is configurable so as to work as an asynchronous server replica system and/or as a synchronous server replica system depending on an attribute included in the input data.

1. An adaptable replica server system comprising:
a primary replica including a primary storage for storing input data and a primary processor configured to process the input data to create output data, and a secondary replica including a secondary storage and a secondary processor configured to create confirmation data upon receiving input data from the primary replica, wherein the replica server system is configured to operate as an asynchronous server replica system or as a synchronous server replica system depending on an attribute associated with the input data specifying a type of the input data, and wherein the replica server system is configured to operate as an asynchronous server replica system for a first type of input data and as a synchronous server replica system for a second, different type of input data.
