The costs of downtime have increased over time, so companies are paying more attention to high availability (HA) today than in the past. Also, the costs for HA solutions have decreased considerably in a way that makes much more sense to invest in protecting business continuity than to undertake the downtime costs.
No one has 100% business continuity, which is why HANA on Power Systems offers HA and disaster recovery (DR) solutions. Figure 1-1 shows the possible scenarios for HA and DR that you can implement. This publication focuses on HANA and SUSE Linux Enterprise Server and SAP HANA mechanisms to provide HA. Other alternatives are documented in SAP Note 2407186.
