Explanation

EMC VPLEX is the next-generation solution for block-level virtualization and data mobility both within and across datacenters. The VPLEX appliance resides between the servers and heterogeneous storage devices. It forms a pool of distributed block storage resources and enables creating virtual storage volumes from the pool. These virtual volumes are then allocated to the servers. The virtual-to-physical-storage mapping remains hidden to the servers. VPLEX provides nondisruptive data mobility among physical storage devices to balance the application workload and to enable both local and remote data access. The mapping of virtual volumes to physical volumes can be changed dynamically by the administrator. VPLEX uses a unique clustering architecture and distributed cache coherency that enable multiple hosts located across two locations to access a single copy of data. VPLEX also provides the capability to mirror data of a virtual volume both within and across locations. This enables hosts at different data centers to access cache-coherent copies of the same virtual volume. To avoid application downtime due to outage at a data center, the workload can be moved quickly to another data center. Applications continue accessing the same virtual volume and remain uninterrupted by the data mobility. The VPLEX family consists of three products: VPLEX Local, VPLEX Metro, and VPLEX Geo. EMC VPLEX Local delivers local federation, which provides simplified management and nondisruptive data mobility across heterogeneous arrays within a data center. EMC VPLEX Metro delivers distributed federation, which provides data access and mobility between two VPEX clusters within synchronous distances that support round-trip latency up to 5 ms. VPLEX Geo delivers data access and mobility between two VPLEX clusters within asynchronous distances (that support round-trip latency up to 50 ms).
