help Dell EMC SRDF FAQ
What is Dell EMC SRDF primarily used for?
Dell EMC SRDF (Symmetrix Remote Data Facility) is an enterprise-grade disaster recovery solution that replicates data synchronously or asynchronously between primary and secondary servers. It enables rapid failover and business continuity within a cluster in case of severe outages.
What is the difference between SRDF/S and SRDF/A replication?
SRDF/S provides synchronous data replication, ensuring zero data loss by writing to both primary and secondary servers simultaneously over short distances. Conversely, SRDF/A provides asynchronous replication, offering greater geographic distance with minimal impact on application performance.
Does Dell EMC SRDF work with non-Dell storage arrays?
No, SRDF is a proprietary software-defined storage technology designed exclusively for Dell EMC Symmetrix, VMAX, and PowerMax enterprise arrays. You must have compatible Dell EMC hardware on both the primary and secondary cluster ends to utilize the replication.
How does Dell EMC SRDF handle an unexpected primary data center outage?
In the event of a primary site outage, SRDF enables rapid failover by immediately promoting the secondary replicated data to an active state. This allows business-critical applications to resume operations from the secondary cluster with minimal data loss and downtime.
