Naji Almahmoud, senior director, SAP Global Alliance, SUSE, told iTWire that high-availability capabilities would ensure continuous access to mission-critical applications and data.
"(The) SUSE Linux Enterprise High Availability Extension offers a flexible, policy-driven clustering solution so customers don't have to worry about service outages," he said. Also offered are, "resource agents to monitor third-party applications like SAP HANA and continuous data replication".
While SAP does run on other databases, Almahmoud said SAP HANA afforded some additional features.
Almahmoud said a typical set-up would include two systems for replication with node 1 acting as an active primary where users were connected and node 2 acting as an active secondary.
"Node 2 is maintained in full sync (data, memory, ...) with node 1, to take over when a component fails on node 1. SAP HANA System Replication does the replication and SUSE High Availability cluster monitors the components' status (software & hardware) on node 1," he said.
"In case of failure on node 1, SUSE solution will automate the failover to node 2 (declare node 2 as primary, and direct users from node 1 to node 2."
Subscriptions to SUSE Linux Enterprise Server include the high-availability capability for no extra charge.
