HP XP Continuous Access Software - Manual (Page 9)

Features
XP Continuous Access Journal provides the following key features:
•
Heterogeneous Storage System Support
Used with the storage system, XP Continuous Access Journal software enables storage
management and disaster recovery in heterogeneous systems, providing maximum
flexibility and support of enterprise-class environments. ◦
◦ XP Continuous Access Journal software supports any storage connected to a storage
system, permitting data to be copied from any supported device to any other supported
device, regardless of operating system or protocol differences. This ensures maximum
flexibility for data distribution as well as increased storage utilization and failover options.
•
More Efficient Replication
XP Continuous Access Journal software uses asynchronous replication driven by the remote
site to minimize impact on primary production systems and takes advantage of journaling, ◦
rather than cache files, to mitigate the high resource usage of other asynchronous
approaches.
◦ Storage usage on the storage system can be minimal, just enough for the journals.
◦ Limited use of cache leaves cache for production application usage, further restoring
primary site storage to its intended role as a transaction processing resource, not a
replication engine.
◦ Advanced three data center capabilities provide a choice of cascade or multi-target
configurations (teams with XP Continuous Access Synchronous for advanced
configurations).
◦ Consistency groups can span multiple storage systems for large enterprise-class applications
requiring unmatched scalability and data integrity.
Note: Check with your HP service representative for detailed feature availability information.
Benefits
The business benefits of XP Continuous Access Journal include:
•
Ensure Business Continuity
Simplifies implementation to meet the most demanding disaster recovery and uptime
requirements, regardless of the type of supported storage platform hosting the
business-critical data ◦
◦ Supports availability of up-to-date copies of data in dispersed locations by leveraging XP
Continuous Access Synchronous
◦ Maintains integrity of a replicated copy without impacting processing, even when
replication network outages occur or optimal bandwidth is not available
◦ Works with storage system replication technology to greatly enhance administrative
productivity and response to and proactive aversion of crises
•
Optimize Resource Usage
Leverages advanced technology to maintain data integrity and optimize the storage/IT
infrastructure for protection of data from any application across a variety of hardware
and software platforms ◦
◦ Optimizes storage resources for more efficient data protection over any distance
◦ Significantly reduces cache utilization and increases bandwidth utilization by leveraging
performance-optimized disk-based journals
