What is EMC SRDF?
What is EMC SRDF?
The Symmetrix Remote Data Facility (SRDF) is a family of software products that facilitates the data replication from one Symmetrix storage array to another through a storage area network or Internet Protocol (IP) network.
What is SRDF group?
All Symmetrix Remote Data Facility (SRDF) operations in PowerHA® SystemMirror® Enterprise Edition clusters are performed on a composite group and not on individual device groups. The composite group that is enabled for consistency is known as the consistency group .
What is SRDF failover?
EMC SRDF logically pairs a device or a group of devices from each array and replicates data from one to the other synchronously or asynchronously. During the SRDF failover operation the R1 devices are write-disabled, the SRDF link is set to Not-Ready (NR), then the R2 devices are write-enabled.
What is concurrent SRDF?
Concurrent SRDF permits the maintenance of two data copies. Cascaded SRDF is a 3 site disaster recovery configuration in which data from a primary site is synchronously replicated to a secondary site, and then asynchronously replicated to a tertiary site.
How does Srdf a work?
SRDF/A operates in asynchronous mode. It is a disaster-restart solution that mirrors data from the R1 devices while maintaining a dependent-write consistent copy of the data on the R2 devices at all times.
What is Srdf in Vmax?
EMC SRDF (Symmetrix Remote Data Facility) is a replication product which can be used to replicate the data from one array to second array. Primary use is for business continuity/disaster recovery. Other use is migrating the data from one array to another.
How do I set up SRDF?
How to Configure an EMC SRDF Replication Group
- Verify that the primary and secondary replicas are synchronized.
- Determine which node contains the primary replica and which node contains the secondary replica by using the symdg show command.
- Enable the secondary replica.
- Swap the RDF1 and RDF2 devices.
What is Srdf Metro?
SRDF/Metro is a new feature available on the VMAX3/VMAX All Flash which provides active/active access to the R1 and R2 of an SRDF configuration. In traditional SRDF, R1 devices are Read/Write accessible while R2 devices are Read Only/ Write Disabled.
How does EMC SRDF work?
How does SRDF replication work?
SRDF software replicates data between two, three, or four arrays located in the same room, on the same campus, or thousands of kilometers apart. SRDF replication modes include: SRDF synchronous (SRDF/S)―SRDF/S replication maintains a real-time copy at arrays that are located within 200 kilometers.
What is SRDF in Vmax?
What is VMAX3?
VMAX3 is a flagship enterprise storage array from EMC succeeding VMAX 10K/20K/40K models. VMAX3 can be configured in 3 models VMAX 100K/200K/400K. The VMAX3 Family with new HYPERMAX OS 5977 release delivers a number of revolutionary changes as claimed by EMC.
Is SRDF compatible with the VMAX3?
SRDF is native to the VMAX3 so there is no need to utilize appliances or bring VPLEX into the mix if that doesn’t fit into your business requirements.
Is there a RecoverPoint splitter for VMAX3?
Since a native RecoverPoint splitter doesn’t exist today with VMAX3, you would have to put VPLEX in front of it to utilize RecoverPoint or go with VM-based replication in RP4VM’s. Comparing RP4VMs to SRDF is comparing apples to oranges since one protects at the VM level and the other protects at the LUN level.
What is the difference between RecoverPoint and SRDF?
Looking at SRDF alone, it has many flexible options for your replication needs but does require VMAX-to-VMAX replication whereas RecoverPoint can enable heterogeneous replication if that is a requirement.
What is the difference between rp4vms and SRDF?
Comparing RP4VMs to SRDF is comparing apples to oranges since one protects at the VM level and the other protects at the LUN level. Both technologies are industry proven technologies with a long history of success and a large customer base.
