Key benefits of unified fabric l.jpg

Key Benefits of Unified Fabric

Reduce overall DC power consumption by up to 8%. Extend the lifecycle of current data center.

Wire hosts once to connect to any network - SAN, LAN, HPC. Faster rollout of new apps and services.

Every host will be able to mount any storage target. Drive storage consolidation and improve utilization.

Rack, Row, and X-Data Center VM portability become possible.
