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 customer impact. As a result, companies cannot afford to have extended downtime. Windows server failover cluster provides automatic failover and load balancing for the cluster roles. Dell EMC SRDF/Metro provides an extended distance solution for Windows Server failover cluster that maintains simplicity, reduces overhead and reduces application downtime in the event of failover.
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 supports a solution featuring HA and DR for Windows Server failover clusters.
