Collapsed Fabric with VSANs
The storage network domains created by VSANs not only leap frog the existing security mechanisms but also deliver the ability to segregate even a single switch into multiple virtual environments. They provide complete separation among different VSANs and guarantee that a device outage or fabric instability is segregated to a single VSAN and doesn’t cause a
This architecture reduces the total number of SANs or fabrics deployed in the data center while maintaining status quo in terms of separating backup/recovery and remote data mirroring domains from the application SAN. Considering the data center real estate and storage consolidation model customers are adopting, VSANs enable a lower TCO solution for the enterprise.
Multiprotocol Support
The MDS 9000 Family of Multilayer Directors and Fabric Switches integrate FCIP and iSCSI onto a single switching module for integrated Multiprotocol capability. The multiprotocol solution provides connectivity options over IP for applications such as disaster recovery. The integration of multiprotocol services along with high speed, high capacity Fibre Channel switching into a single platform allows customers to address their
