System Classification (SAP NetWeaver AS)

Definition

We distinguish between the following kinds of SAP system from the high availability viewpoint:

·        Standard SAP system

The standard SAP system already contains a range of possibilities to improve the availability of your SAP system without purchasing additional software or hardware.

·        High availability SAP system

A high availability SAP system consists of additional hardware and software, chosen in consultation with your SAP partner. For example, you can use a cluster solution to protect the database or the enqueue service.

·        Business continuity SAP system

A business continuity SAP system involves a standby SAP system, usually at a remote site. This enables you to recover from disasters such as the destruction of your primary SAP system.

Use

The classification is useful when discussing high availability aspects of the SAP system:

·        Standard SAP system

You use a standard SAP system when you have no special additional requirements for high availability.

·        High availability SAP system

You use a high availability SAP system when you need to ensure fault-tolerant operation of your SAP system. A high availability SAP system is robust without being fully disaster-proof.

·        Business continuity SAP system

You use a business continuity SAP system for critical operations when it is essential that the system is always available. In the event of a disaster, such as a fire at the primary site, you can resume operations immediately or quickly from the standby site.
