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. 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.
NOTE: HP SE integration for SAP ACC is only supported with the Windows version of the HP
Storage Essentials SRM Enterprise Edition product suite.
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 the relationship between the 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 (
libsapacosrep_hp.sl
and libsapacosprep.so for HP-UX hosts) 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 storage
array manipulation (to present and un-present storage to/from the Managed Node). The
Application Integration Software for SAP ACC is also responsible for protecting storage devices
that are not currently accessed by any Managed Node.
