A new version of the How-To guide for LaMa 3.0 provisioning and adaptive design principles has just been published. It gives an overview of the system provisioning processes that are supported by SAP Landscape Management, Enterprise Edition.
The focus of the document is on storage based provisioning and for this it is critical to follow the adaptive design principles. This applies whether the landscapes are on-premise or in one of the supported cloud environments.
In a nutshell the adaptive design has three principles:
Virtual Hostname & IP
• Virtual hostnames for SAP are bound to virtual IPs
• Network connections are to virtual hostname and not primary hostname of server
• Note: DNS entries need to be A records and not CNAME records
Dynamic Storage Layout
• Shared connectivity to storage devices
• Block storage (SAN) – can be detached and attached to different hosts but one host use at a time
• File storage (NAS) – can be shared simultaneously on multiple hosts
Central User Management
• User accounts are created in a nameserver such as Active Directory or LDAP
