VPLEX for Storage Federation: A New Approach to Virtual Storage

EMC’s VPLEX can integrate with VBlocks and leverage VMware, Cisco, and EMC packages which provide a solution for computing, network, storage, and management.

VPLEX is a pay as you grow module, starts small and grow as you need. The VPLEX comes in two configurations:

• VPLEX Local – allows data mobility across arrays in a local data center in a non-disruptive fashion

• VPLEX Metro – enables data access across two locations (within 60 Miles)

EMC plans to introduce two more configurations of VPLEX:

• VPLEX Geo – will support data access across different geographical locations (over 60 Miles)

• VPLEX Global – will allow data access across multiple global locations, this will allow companies to reduce processing costs as it can take advantage of lower energy costs during the day and night

EMC has managed to overcome remote data mobility challenges such as: performance latency, bandwidth limitations, and data inconsistency. EMC will address these issues with a global distributed cache coherency design using VPLEX engines.

If this is successful, the approach could have some truly valuable use cases in both local and global configurations, an example is vMotion over distance (more information can be found at: http://kb.vmware.com/kb/1021215 ).

I’m looking forward to see how this product will be implemented and answer some business and technological challenges.
