SRDF family of products
The EMC Symmetrix Remote Data Facility (SRDF) family of
replication software offers various levels of Symmetrix based
business continuance and disaster recovery solutions. The SRDF
products offer the capability to maintain multiple, host-independent,
mirrored copies of data. The Symmetrix systems can be in the same
room, in different buildings within the same campus, or hundreds to
thousands of kilometers apart.
By maintaining copies of data in different physical locations, SRDF
enables you to perform the following operations with minimal
impact on normal business processing:
â—† Disaster restart
â—† Disaster restart testing
â—† Recovery from planned outages
â—† Remote backup
â—† Data center migration
â—† Data replication and mobility
Note: The EMC Symmetrix Remote Data Facility (SRDF) Product Guide contains
specific information on the SRDF family of products.
Base SRDF family
products
The SRDF family consists of three base solutions:
◆ SRDF/Synchronous (SRDF/S) — High-performance,
host-independent, real-time synchronous remote replication from
one Symmetrix to one or more Symmetrix systems.
◆ SRDF/Asynchronous (SRDF/A) — High-performance extended
distance asynchronous replication using a Delta Set architecture
for optimal bandwidth utilization and minimal host performance
impact.
◆ SRDF/Data Mobility (SRDF/DM) — Rapid transfer of data from
source volumes to remote volumes anywhere in the world,
permitting information to be shared and content to be distributed,
or information consolidated for parallel processing activities.
