EMC Corporation has released two new replication software products that help Symmetrix DMX customers reduce cost, extend distances and increase the frequency of local and remote replications.
SRDF/A is a high-performance, extended-distance replication software that uses EMC-patent-pending technologies to maintain a recoverable and restartable copy of data across any distance.
EMC Snap is a space-saving replication software for high-end storage that uses only a fraction of the storage capacity previously needed for local replications. This, says Alex Robertson, Technology Solutions Group Manager, EMC SA, enables mainframe and open systems users to make more copies of data for re-purposing and protection.
"Through its multidimensional approach to the high end, EMC is delivering customer benefits across multiple points of deployment - open, mainframe and the entire enterprise. With the addition of SRDF/A and EMC Snap, EMC has amassed a suite of replication offerings that set a new design point for the industry," Robertson adds.
Using EMC`s Delta Set technology, SRDF/A enables customers to maintain a recoverable and restartable remote copy of data at all times, at any distance and with no host application impact.
"Customers wanting to replicate data across long distances historically have been handcuffed by existing implementations," says Robertson. "Traditional asynchronous solutions on the market today have done little to address high telecommunications costs, poor performance and cumbersome manageability.
"SRDF/A delivers high-performance, extended-distance replication and reduced telecommunication costs while leveraging existing management capabilities and minimising potential data exposure."
The key SRDF/A innovation is its Delta Set technology, which eliminates transmission of redundant changes. Compared with other replication approaches, SRDF/A uses considerably less bandwidth. Robertson confirms that early tests using real-world customer environments demonstrate that SRDF/A can reduce bandwidth requirements by as much as 30%.
EMC`s Snap software offers Symmetrix DMX customers an economical, space-saving alternative to full-volume copies. Available for both mainframe and open systems environments, EMC Snap requires only a fraction of the additional capacity needed to make full volume copies.
According to Robertson, this ability to satisfy mixed service levels simultaneously by offering full-copy and space-saving replication solutions differentiates Symmetrix DMX from all other high-end competitors.
"With EMC Snap, creating copies no longer requires 100% of the capacity of the source volume; only a small percentage (typically 30%) of the source capacity is required," he says. "The combination of EMC Snap and EMC TimeFinder full-volume replications enables Symmetrix DMX users to meet a wide range of service levels when performing local replications."
