DRNet™ products support all database types,
with or without TMF protection
Supports Expand and TCP/IP for inter-system connectivity
No source code changes are necessary for implementation |
DRNet/HB™ performs all required database synchronization from the primary to the backup system. This provides the functionality to perform a system switch from a primary to the backup system with a minimum window of outage time, often in minutes or less. The primary factors involved in switching time are the amount of time required to start the backup application and to switch communications to the backup system.
|
DRNet/HBR™ collects and forwards database changes originating from the backup system (as well as for the primary). This is used to recover data created on the backup system where application activity is taking place as a result of a system switch. When the primary system becomes available the databases are synchronized, allowing a controlled switch back to the primary without loss of database changes.
|
DRNet/APS™, or Application Partitioning System, allows applications to be partitioned across multiple HP NonStopT Server nodes where physical or geographic separation of applications is desired. DRNet cross-feeds database changes between two or more NonStop Server nodes in a "dual mode" fashion. A common database image is maintained across all locations, regardless of where database changes originate.
The benefits of APS include increased redundancy and flexibility, better response time and continuous use of the NonStop hardware. DRNet/APS supports both TMF and non-TMF database environments
|
DRNet/OPEN extends DRNet's HP NonStop Server-based data replication product line to other hardware environments. DRNet/OPEN collects database updates from NonStop Servers and uses our powerful messaging middleware to replicate data to most OPEN platforms, including Windows®, Unix®, and Linux®.
