4. Adaptive Computing
Adaptive Computing is a new approach to design hardware, software and system services following the business-driven need to permanent change and adaptability
It is about empowering the customer to be able to run any service any time on any server. In this context the word application service is used to describe any kind of scenario, solution or application component
A computing infrastructure is called adaptive, if it allows the dynamic assignment of hardware resources to serve specific application services. In this way, SAP NetWeaver enables an 'Adaptive Computing Infrastructure' and thus ensures that business solutions based on SAP NetWeaver run at peak cost efficiency

PEOPLE INTEGRATION
SAP NetWeaver provides a way to virtualize application services, and provides a single central point of control for flexible compute resource assignment for existing and new code to run on dedicated/changing hardware.

Adaptive computing is not just the under laying infrastructure for the Integration platform SAP Netweaver that allows us to use resources very flexible and efficient.
AC also supports the “Lifecycle Management” :
Implementation of new solutions: start on small servers, grow with your needs
Upgrade: Take a snapshot, upgrade your snapshot system…(In combination with advanced storage functionality)
OS upgrades, Tests

Storage
Have dedicated resources for computing, storage, network and control
Pool them and share them – if appropriate
Define application services and virtualize them
Key of the concept is the separation of the infrastructure into building blocks

Computing nodes
sapacosprep: must be available on each computing node and will be called from the ACC via ssh to prepare the OS (NW interface, mount, …). After sapacosprep has finished, the application service is able to start.
saposcol: is a general available agent from SAP for collecting OS information per host, which writes it’s data to the local shared memory. This agent is started each time after the boot of the server.
sapacoscol: reads data (hostnames, OS version, CPU utilization, …) out of the shared memory and transfers it to the ACC. This agent is started each time after the boot of the server. During each start of the computing node the xml output of this agent (saposcol –b) is used to register this host with sldreg at the central SLD (a single registration process would be enough).
Application Service: registers once via the transaction RZ70 in the central SLD.
• ACC Station
SLD: is the “data store” for the landscape and configuration data of the adaptive services and the adaptive hosts. The ACC connects to the SLD via WBEM. The Solution Manager acts as the design engine for the adaptive environment and gets the basic data from the SLD and writes the “adaptive data” after the modeling process back to the SLD. The communication with the Solution Manager is done via RFC calls.
ACC: The Adaptive Computing Controller as the center of infrastructure management solution, communicates with different components of the infrastructure:
sapacoscol: as long as this agent reports any application specific virtual interface to the ACC, the controller shows the physical host, where the interface is up, as used for this service.
sapacosprep: is the program, which initiates the OS specific preparations like configuring the NW interfaces, managing the mounts, …. This program is directly called by the ACC via SSH and reports back to the ACC the return codes and the output of the OS commands.
The only direct communication between the SolMan and the ACC is the notification functionality, that in the SolMan some data was changed. The protocol is HTTP.
Controller Command Interface: The ACC communicates with external programs via the Controller Command Interface (CCI). This interface provides basic functionality of the ACC to external programs the. The communication protocol is HTTPS.
SAP Standalone Gateway: is the communication platform for all RFC based communication between SLD, SolMan and the “to managed” systems.
