• Higher qualities of service - The DataPower XC10 appliance can provide faster
and more robust replication than WebSphere Application Server alone. It can
provide an assured level of replication as it will retry saving a session object if
the initial attempt fails. Additionally, HTTP session data can be replicated without
the performance overhead seen when using the synchronoous replication in
WebSphere Application Server.
• With the DataPower XC10 appliance, session data is not restricted to a WebSphere
Application Server cell boundary as they are with WebSphere Application Server
on its own. The DataPower XC10 appliance was built to serve as a easily installed
solution outside WebSphere Application Server and automatically sets up stand-
alone grid clusters that can be used by many applications and cells.
• Cross application and platform access - It can be easy to configure the DataPower
XC10 appliance to allow different applications to access the session object for the
same user. Because it does not have a dependency on WebSphere Application
Server, this replication can actually be from non-WebSphere Application Server
environments such as WebSphere Application Server Community Edition (based
on Apache Geronimo).
Extension for WebSphere Application Server (WAS) Dynamic Cache Service
The DataPower XC10 appliance provides a consistent, distributed cache for
enterprise applications running on WebSphere Application Server. The Dynamic
Cache API (informally known as DynaCache) is available to Java
TM
Extended Edition
(Java EE) applications that are deployed in WebSphere Application Server and can
be leveraged to cache business data, generated HTML, or to synchronize the cached
data in the cell by using the data replication service (DRS). Previously, the only
service provider for the Dynamic Cache API was the default dynamic cache engine
built into WAS.
With the DataPower XC10 appliance, you can now use the dynamic cache service
provider interface in WAS to plug into the Dynamic Cache. By setting up this
capability, you can enable applications written with the Dynamic Cache API or
applications using container-level caching (such as servlets) to leverage the features
and performance capabilities of the DataPower XC10 appliance, including replication
over the network, high availability, scalability and cache partitioning.
Elastic Dynacache (Plug-in for WebSphere Application Server Dynacache) provides
more efficient storage of data in a grid rather than multiple redundant copies that
are difficult to keep synchronized.
Web side-cache
Each DataPower XC10 unit provides a large 160 GB cache that is to the side of the
application (not within the same Java Virtual Machine), allowing it to be accessed via
a network connection. This can
• Accelerate your applications' performance by putting your data closer to your
applications/service
• Reduce power consumption and rack space
• Lower your dependencies on more expensive systems and data bases.
DataPower XC10's fault tolerance means higher user satisfaction, faster task
completion, and increased conversion rates.
