Toward Zero Downtime with SAP HANA and More on IBM Systems


Whether you are running business-critical systems like SAP HANA on IBM Power or managing highly transactional workloads on IBM Z, maintaining business continuity is essential in today’s nonstop business environments.

Many companies around the world are looking to ensure faster response times and low maintenance overheads through high availability techniques and technologies.  One such company is Greenply Industries Limited, India’s largest interior infrastructure company and a leader in the manufacture of plywood and medium density fiberboard.  Greenply implemented SAP HANA on IBM Power systems, using its in-memory technology to enable full-spectrum visibility throughout their supply chain and supporting faster, smarter business decisions.  And because ultra-high availability of services was essential, Greenply used the SAP-certified SUSE Linux Enterprise High Availability Extension, incorporating a clustering solution for application servers and solutions for highly available storage and network load-balancing.

Another company, C&A in the Netherlands, has grown to become one of the world’s largest fashion retailers.  Zero downtime is important to them as well in order to support sales across all of their channels around the world.  C&A depends on integrated processes and business-critical applications like SAP running reliably at all times on an IBM Z system.  With customers increasingly turning to digital channels, the fashion retail giant relies on tightly integrated workflows to provide a seamless shopping experience – so high availability is extremely important to them.

Besides the reliability, availability and serviceability characteristics of IBM Systems and SUSE Linux Enterprise Server, the list below identifies additional features and benefits for increasing uptime for business-critical workloads:

SUSE Linux Enterprise High Availability Extension

  • Failover clustering
    Meet SLAs by including redundancy for your business-critical workloads. Set up clusters among physical nodes or virtual guests.
  • IPv4, IPv6 load balancing
    Automatically distribute stateless server workloads (e.g., web service) to achieve high availability.
  • Cluster test drive
    Simulate and validate cluster setup before actual failover happens.
  • Resource agents
    No-extra-charge resource agents for popular open source and third-party applications, such as SAP, to ensure availability for your key workloads.
  • Cluster rolling update
    Ensure service uptime by updating nodes sequentially without full cluster downtime.
  • Metro-clustering
    Combat regional accidents by clustering with nodes across local distances.


Geo Clustering for SUSE Linux Enterprise High Availability Extension

  • Geo-clustering
    Bridge clusters of any distance to ensure business continuity.


SUSE Linux Enterprise Live Patching

  • Live kernel patching
    Install critical security patches before the next service window, without rebooting.


SUSE Manager

  • Automated patching
    Reduce human errors by automated patch management.
  • Patch pre-loading
    Pre-load patches to systems prior to applying them, reducing downtime in patching.
  • Package lock
    Lock your packages to maintain the status of business-critical applications and protect them from unwanted changes.


Server and operating systems with mature and proven features and functions are playing more and more critical roles in keeping your services available. SUSE has been helping customers to reduce downtime by further exploiting reliable hardware, enhancing service avail­ability with clustering and minimizing human mistakes with ef­ficient tools. When it comes to zero downtime on IBM Power and Z systems running business-critical applications like SAP, think SUSE!
