SAP Adaptive Computing Overview 10
Control
Controlling the adaptive landscape is performed from within the SAP application using the ACC
software that is build on top of the SAP NetWeaver® application.
Application Integration Software for SAP ACC
To support a fully automated SAN storage movement between managed nodes, HP has developed
the Application Integration Software for SAP ACC. The Application Integration Software for SAP
ACC consists of the following parts:
• HP Storage Essentials SRM Enterprise Edition
• Active host management interface
• Application Integration Software for SAP ACC
HP Storage Essentials SRM Enterprise Edition
The HP Storage Essentials SRM Enterprise Edition product suite provides an integrated array
management functionality for storage provisioning and managed node management. The
Application Integration Software for SAP ACC is built on the HP Storage Essentials SRM API
functions, and it utilizes the HP Storage Essentials SRM database for host objects and the storage
management functions to present and un-present storage to/from any managed node in the
landscape.
Active host management interface
The Application Integration Software for SAP ACC provides an active host management interface
for HP SIM to perform active management on the managed nodes for storage management. For this
to work, it is necessary to have all managed nodes discovered in HP SIM and HP Storage Essentials
SRM and to configure a Secure Shell (OpenSSH) communication to each managed node.
Application Integration Software
The Application Integration Software has three main functions:
• Maintain relationship between Storage Resource Identifier (SRID) and the physical storage
devices - Since the SAP ACC does not maintain a list of physical devices associated to a SAP
instance, but rather only an identifier for the Storage Resources used by an SAP instance, it is
necessary to maintain a link between the SRID used in the SAP ACC configuration and the list of
physical devices used by the instance. The Application Integration Software for SAP ACC
provides an interface that lets you easily associate the Storage Resource Identifier with a specific
mount point and associated physical devices.
• Provide the interaction between SAP ACC and storage management - The Application
Integration Software for SAP ACC provides the vendor specific storage API
(libsapacosprep_hp.dll) to integrate with the SAP “sapacosprep” agent on the managed node.
The storage API forwards storage related requests to the Application Integration Software for
SAP ACC.
• Implement the flow of operation necessary to “start”, “stop” or “relocate” Storage Resource
to/from a managed node - This includes the necessary actions on the managed node to
discover, configure and mount/unmount file systems on the individual computing systems and
