SAP ACC overview

The following section provides some basic background on the structure and functionality of the SAP

Adaptive Computing Controller (SAP ACC). For more detailed information, please refer to the

documentation provided by SAP on this subject.
The following topics are covered in this section:

The virtual SAP landscape

To create an adaptive SAP landscape, it is necessary to have a virtual application setup. The

application and all the resources belonging to the applications (network and storage) must be

grouped together into one unit that can be moved from one system to another independent from

anything else on the system.
The following figure describes the components to create a virtualized application.

The components to create a virtualized application

A SAP instance consists of network resources that includes a virtual host name and a virtual IP

address. This virtual IP address is different from the dedicated server IP address assigned to the

hardware. The virtual IP address of the application makes it possible to connect to the application,

independent of the hardware, anywhere in the landscape.
The SAP instance also consists of physical storage, either Network Attached Storage (NAS) or

Storage Area Network (SAN)-attached storage. The storage is made up of file systems located on

logical devices (Ldev) from a storage system. The SAP ACC groups all the storage components of an

instance under the Storage Resource Identifier (SRID) and lets you create a custom name for the

storage component of the instance.
The HP Storage Essentials Storage Resource Management (SRM) Enterprise Edition Microsoft

Windows Application Integration Software for SAP ACC provides a link between the SRID created

in SAP and the physical storage resources that is associated with that instance. This allows HP

Storage Essentials SRM to Present or Un-present this storage from any host in the SAN.
