EMC Ratchets Up Replication

EMC Corp. (NYSE: EMC) today moved to strengthen replication software for its Symmetrix systems that are coming under attack from new releases by Hitachi Data Systems (HDS) and IBM Corp. (NYSE: IBM).

EMCs high-end Symmetrix is the target for the Tagmastore Universal Storage Platform (USP) that Hitachi launched last month, and the next-generation Shark that IBM will announce next week (see Hitachi Struts Mr. Universal).

With that one-two punch imminent, EMC upgraded its Symmetrix Remote Data Facility (SRDF) replication software, including a feature called Star that allows distance replication among three data centers. If the primary center goes down, the two secondary data centers can continue to replicate data. Previously, the primary data center had to be involved in the replication.

"Now if the primary site fails, the two survivors can find each other," says Chuck Hollis, EMC's VP of storage platforms.

EMC is the first vendor to announce this feature.
