VMware is shipping a new version of vCenter Site Recovery Manager (SRM) with expanded storage support, tighter controls and expanded failover capabilities for disaster recovery for virtual machines.
VMware vCenter Site Recovery Manager 4 – which is actually the second version of the product, but has been named to match the vSphere 4 operating system – offers several new features to help users automate the disaster recovery (DR) process in VMware environments.
With the new release, Site Recovery Manager now supports NFS-based storage replication, is compatible with VMware vSphere 4, and includes many-to-one failover using shared recovery sites.
Support for vSphere 4 means users can utilize some of the more advanced functions of the operating system, including fault tolerance for better performance and protection of applications.
VMware group product marketing manager Jon Bock says the new release automates some of the manual processes associated with disaster recovery.
"Before Site Recovery Manager, a lot of customers were taking care of the process steps manually using scripts or third-party tools for disaster recovery. The problem with that is the larger the VMware environment gets, the more painful it becomes to manage," says Bock.
In addition, customers can use Site Recovery Manager 4 in mixed environments consisting of different iterations of VMware ESX and vSphere 4.
VMware has also improved the scalability of Site Recovery Manager. The initial release of the product, which is in use at more than 2,000 customer sites, only supported 500 virtual machines (VMs). Version 4 is capable of protecting up to 1,000 VMs.
A number of storage vendors have pledged support for Site Recovery Manager 4, including 3PAR, Compellent, Dell (EqualLogic), EMC, FalconStor, Fujitsu, Hitachi Data Systems, HP, IBM, LSI, NetApp and Xiotech.
VMware vCenter Site Recovery Manager 4 is priced on a per-processor basis. Pricing is $1,750 per processor.
