20090276657 | MANAGING CLUSTER SPLIT-BRAIN IN DATACENTER SERVICE SITE FAILOVER - A central controlling service for datacenter activation/deactivation control in a cluster deployment to assist in preventing a split-brain scenario. The central controlling service provides a central point of control in the datacenter for application servers to periodically query as to whether to go offline, online, or normal. Redundancy of the central service facilitates detection of datacenter failure by the redundant services interacting to resolve the state of control information. This control information is then used to answer the server queries. On startup from a datacenter failure, a single instance of the central service queries other redundant instance(s) to determine if the single instance is starting up from a datacenter-wide failure or from operations other than total datacenter failure. If the failure is datacenter-wide, a central service protocol assists in resolving to the single service keeping the associated datacenter servers offline; otherwise, the server queries are answered to go online. | 11-05-2009 |
20090319583 | INTEGRATED DATA AVAILABILITY AND HISTORICAL DATA PROTECTION - A single native integrated system may be provided for replicating data to one or more copies of high-availability data and for replicating the data to one or more copies of backup data. The data may be replicated, in near real-time, to the one or more copies of high-availability data as changes occur to the data. The data may be replicated and later incorporated to a copy of the backup data at different points in time. The single native integrated system may have a single set of functions for replicating the data to the one or more copies of high-availability data and for replicating the data for the one or more copies of the backup data. Administrative access to the one or more copies of high-availability data may be isolated from administrative access to the one or more copies of the backup data. | 12-24-2009 |
20090327519 | ADDING INDIVIDUAL DATABASE FAILOVER/SWITCHOVER TO AN EXISTING STORAGE COMPONENT WITH LIMITED IMPACT - High availability architecture that employs a mid-tier proxy server to route client communications to active data store instances in response to failover and switchover. The proxy server includes an active manager client that interfaces to an active manager in each of the backend servers. State information and configuration information are maintained separately and according to semantics consistent with needs of corresponding data, the configuration information changing less frequently and more available, the state information changing more frequently and less available. The active manager indicates to the proxy server which of the data storage instances is the currently the active instance. In the event that the currently active instance is inactive, the proxy server selects a different backend server that currently hosts the active data store instance. Client communications are then routed to the different backend server with minimal or no interruption to the client. | 12-31-2009 |

20110145565 | FEDERATED AUTHENTICATION FOR MAILBOX REPLICATION - A data replication mechanism is proposed that relies on existing federation infrastructure enabling distributed authentication instead of storing and using explicit credentials for a remote forest.

20110167039 | DISTRIBUTED THROTTLING FOR MAILBOX DATA REPLICATION - Distributed mailbox data replication agents are employed to adjust load on mail system resources by enabling the agents to receive a throttling policy, resource capacity, and current usage information.
