IBM AIX High Availability, Disaster Recovery and Storage
SAP uptime requirements go towards zero downtime. To support this SAP target IBM provides a set of technolgies. Virtualization, a cluster software and data redundancy are the core technologies. More about virtualization can be found on the AIX Virtualization topic page. The focus here will be on PowerHA - formerly HACMP - as cluster technology and the IBM Storage features protecting and mirroring data.
Since 2009 a refresh of SAP based solutions for high availability and disaster recovery is ongoing to provide End-to-End guidance.
The IBM Redbook "IBM PowerHA SystemMirror 7.1.3 for AIX Reference Guide" is the 2014 implementation Guide for SAP NetWeaver components including the SAP HA API for the SAP Near Zero Downtime operations of SUM. It provides mandatory guidance in the following areas:
- planning the hardware, network and file systems
- include additional SAP, DB and cluster components into the HA concept
- migration from older PowerHA Smart Assist for SAP releases
- administrative tasks
Assistance for SAP High Availability Deployments
Plan, deploy or verify SAP HA setups requires a combined skillset of Cluster and SAP knowledge. To get personal assistance for cluster deployments the ISICC provides resources and material. To get an overview please open an ISICC info request trough following e-mail: firstname.lastname@example.org Subject: SAP HA Deployment Services.
A joint IBM SAP proof of concept presenting an end-to-end infrastructure solution for mission critical SAP Supply Chain Management using Advanced Planning and Optimization (APO) and/or Available to Promise (ATP). Each single point of failure is provided with an HA solution including the new PowerHA Hot Standby for SAP liveCache. Hot Standby is an integration of the SAP liveCache via API to IBM storage functionality. The ABAP database is covered by similar quick recovery functionality of DB2 HADR. Both the Tivoli SA MP and PowerHA clustering solutions are covered. Storage virtualization provided by the IBM SAN Volume Controller extends the flexibility and resiliency of the end to end solution based on Power7 and VIOS.
Executive Summary: Using IBM PowerHA SystemMirror for AIX to implement High Availability and Disaster Recovery for SAP Applications
The Executive summary highlights the features of an end-to-end business resiliency solution based on PowerHA (HACMP). It also references the technical implementation and documentation.
