High Availability (HA) and Disaster Recovery (DR) capabilities are needed to protect mission critical data. The impact of not having a robust infrastructure is downtime, which translates to financial and client impact. As a result, companies cannot afford to have extended downtime. Oracle RAC provides automatic failover and load balancing for the database instances in a local cluster, with host-based mirroring options for Extended RAC across distance, though these often increase complexity and overhead. Dell EMC SRDF/Metro provides an Oracle Extended RAC solution that maintains simplicity and reduces overhead.
Smart DR extends SRDF/Metro to allow an SRDF/A (Asynchronous replications) leg to a remote site, where both sides of the SRDF/Metro leverage a single remote copy of the data. SRDF/Metro together with Smart DR allows combining High-Availability (HA) with Disaster Recovery (DR) solution for Oracle workloads.
