The following is a high level diagram of the SAP ACC Architecture.
Figure 4 Architecture for SAP Adaptive Computing Controller
The ACC station or Control node consists of the NetWeaver 7.1 Java Engine and the Adaptive
Computing Controller software. The ACC software communicates with the System Landscape
Directory (SLD) to derive a list of Managed Nodes installed in the SAP Landscape. Each Managed
Node needs to register itself in the SLD using remote function calls, and the SLD collects status
information from the Managed Node using the saposcol agent installed on each Managed Node.
The gateway process can be implemented either as a standalone or as an integrated gateway
system.
All Adaptive Computing operations are initiated and controlled from the SAP ACC control node
using the GUI provided by SAP.
SAP ACC version 7.1 utilizes the SAP Host Agent infrastructure (sapacosprep, saposcol, sldreg, and
so on), which is installed on each Managed Node in the system landscape to initiate all host-based
operations. This agent receives command operations from the central SAP ACC controller and
executes the necessary integration modules to enable adaptive computing functions on the
Managed Node.
Internally, the SAP host agent’s “sapacosprep” is made up of a platform/partner independent
module and an API that enables partners to integrate their platform and storage solutions by
