EMC Boosts Net Storage Options

Enterprise storage vendor EMC this week announced enhancements to two of its storage management software offerings designed to ensure that end users can access data even in the event of a host computer failure.

Both software offerings work in conjunction with EMC's Symmetrix Enterprise Storage devices, which enable companies to back up and retrieve data processed by mainframes, mid-range systems and servers.

Symmetric Remote Data Facility (SRDF), which replicates data across WANs, now can work across more than two sites. With this new multihop mirroring capability, only updated data is replicated to a third Symmetric site, cutting telecommunications costs and resynchronization time. Source sites and target sites can also exchange roles and provide mirroring for each other in the event of failure. Pricing for SRDF starts at US$60,000.

EMC's other software upgrade, TimeFinder 3.21, makes data easier to access by providing copies of it locally or across a WAN via SRDF. The new edition includes the ability to update only data that has changed since the last update, conserving disk space and improving performance. Pricing for TimeFinder starts at $72,000.

Dave Hill, a senior analyst for Aberdeen Group in Boston, says any software that reduces risk and increases availability of data is essential. "Enterprises simply cannot afford not having data available to them when they need it. Not only can lost data mean revenue loss, but it takes away from the productivity of people in the organization," he says.
