EMC claims NFS advantage in integration of Celerra and VMware Site Recovery Manager

EMC Corp. Monday sent out a release saying its Celerra multiprotocol storage systems now officially have a plug-in available for VMware Inc.’s vCenter management console and Site Recovery Manager (SRM) failover and failback.

At first, this seemed like a ho-hum announcement. Plug-ins that integrate with vCenter are part of the new standard APIs VMware is making available for partners — everyone and their brother seemingly has something along these lines already (including EMC, which introduced a management plug-in for its Clariion and Symmetrix disk arrays last year). Ditto integration with Site Recovery Manager — FalconStor Software, for example, launched an SRM plug-in for its Network Storage Server (NSS) last year around the time of VMWorld in August.

But EMC director of unified storage marketing Brad Bunce claimed EMC’s integration of automated failback for VMware environments running on NFS is unique. “The difference [between the Celerra plug-in and competitors] is that failback is automated without requiring advanced scripting in the NFS environment,” he said.

At least one competitor acknowledges that the NFS support with automated SRM failback is not something it has yet offered — “As an NFS mounted device Celerra may be the only product with auto failover for SRM,” wrote Falconstor director of marketing Fadi Albatal in an email to Storage Soup. However, he added, “from our side, we can say, welcome to the party–you’re six months behind. Falconstor’s SAN virtualization and DR solutions have a block storage service for SRM and our plug in has an auto-discovery feature that eliminates the need for scripting and ensures full integration with VMware SRM.”

EMC’s vCenter plug-in for management also includes automated provisioning features for VMware in Celerra NFS environments, including automatic mounts to ESX servers and clusters, virtual machine cloning, and compression.
