The Virtual SAP Landscape
To create an adaptive SAP landscape, it is necessary to have a virtual application setup. The
application and all the resources belonging to the applications (network and storage) must be
grouped together into one unit that can be moved from one system to another independent from
anything else on the system.
The following figure describes the components to create a virtualized application.

Components to create a virtualized application
A SAP instance consists of network resources that include a virtual host name and a virtual IP
address. This virtual IP address is different from the dedicated server IP address assigned to the
hardware. The virtual IP address of the application makes it possible to connect to the application,
independent of the hardware, anywhere in the landscape.
The SAP instance also consists of physical storage, either Network Attached Storage (NAS) or
Storage Area Network (SAN)-attached storage. The storage is made up of file systems located on
logical devices (Ldev) from a storage system. The SAP ACC groups all the storage components of an
instance under the Storage Resource Identifier (SRID) and lets you create a custom name for the
storage component of the instance.
