EMC's new Replication Enabler for Exchange 2010 software utility lets customers manage synchronous replication...
through RecoverPoint across heterogeneous storage arrays or MirrorView for its midrange Clarrion arrays through the Exchange interface. EMC has yet to integrate its high-end enterprise Symmetrix Remote Data Facility (SRDF) replication application with Exchange, but it is on the vendor's roadmap, said Bob Madaio, director of the Microsoft global alliance for EMC.
Also newly integrated with Exchange 2010 is EMC's AutoStart software, which continuously monitors application status and automatically spins up a replicated copy of a host at a secondary data center in the event of a failure. EMC customers can also manage Exchange 2010's database availability groups alongside SAN-based replication tools using EMC's Replication Manager software.
"The advantage of an array-based tool versus a built-in tool is that if a user has an SLA [sevice-level agreement] requiring zero data loss, it requires SAN-based synchronous replication," he said. "Also, this provides a common disaster recovery management method for multiple applications."
"The advantage for customers if they're a large Exchange shop is that they might have an Exchange operator that understands the management console," said Ray Lucchesi, president of Silverton Consulting. "There are a lot of application nuances that have to take place to do a proper failover."
EMC also has RepliStor, a host-based replication tool that could be seen as competitive with native tools like the ones included in Exchange 2010, but Madaio said "we consider ourselves leaders in SAN-based replication – what we want to focus on is choice."
EMC also said it had tested Exchange 2010 and certified support for it with its disk arrays. Exchange 2010 consulting services are also currently available.
