Reduce SAN investment with Flexible Shared Storage in the RHEV environment
Veritas InfoScale Solutions offer the Flexible Storage Sharing (FSS) technology that enables inclusion of SSDs or HDDs to work alongside SAN or DAS in your network. The flexibility to use low-cost SSDs, HDDs alongside SAN network, gives you the opportunity to lower the total cost of ownership (TCO) and provides flexibility for future server or storage investments.
FSS enables network sharing of local storage, DAS or internal, across a global namespace to provide data redundancy, high availability, and disaster recovery without the need of shared storage. Using network interconnect between the nodes, FSS allows network shared storage to co-exist with physically shared storage.
The network sharing of local storage made available by FSS means that physically shared disks are not needed in your storage environment. You can manage your storage environment by cost effectively adding SSDs or HDDS or arrays to your existing storage environment based on storage needs. The total cost of ownership (TCO) for your storage hardware infrastructure is vastly reduced.
FSS has the potential to transform your storage environment without external shared storage or a SAN network.
For more information on administering FSS, refer to the Storage Foundation Cluster File System High Availability Administrator's Guide.
Consider the use cases of live migration or disaster recovery of virtual machines in an RHEV environment with FSS enabled for the underlying storage.
For live migration, the virtual machines can use SF components as backend storage configured for FSS. The investments on storage are vastly reduced as FSS lets you use commodity hardware alongside your existing network, serving compute and storage needs from the same servers..
For disaster recovery, VVR provides data replication across dispersed data centres which use Storage Foundation as the backend storage. If the volumes used for replication are created on SF components and the underlying storage is configured for FSS, you get a highly reliable storage management solution that is running on low-cost commodity hardware.
