SAP Adaptive Computing Overview 8
NOTE: Platform specific libraries are required to install or convert a SAP installation to a virtual
landscape. These libraries enable virtual IP addresses on the Managed Nodes.
Virtualized Data
Adaptive Computing also implements the concept of virtualizing the application data into a single
group of data devices (Storage Resources) that can be moved between physical Managed Nodes.
The first requirement to accomplish data virtualization is to ensure that all the data required for the
application is located on a dedicated set of storage devices. For the Application Integration
Software for SAP ACC, it is required that all the storage devices for a specific SAP application are
located on a central storage system with SAN access from all of the Managed Nodes. In the SAP
ACC, the set of physical Storage Resources that are required for a specific SAP instance are
identified by a Storage Resource Identifier (SRID). This identifier provides the link between the SAP
ACC application and the Application Integration Software for SAP ACC.
The Application Integration Software for SAP ACC is specifically designed to support SAN-attached
storage in an adaptive landscape.
The following diagram shows the relationships between physical storage devices and their usage on
HP-UX systems.
