UCS 2.0: Cisco Stacks the Deck in Las Vegas | M. Sean McGee:

The UCS 6248UP Fabric Interconnect, similar to the Nexus 5548 platform, provides up to 48 Unified Ports in a single Rack Unit (1 RU). Unified Ports are SFP+ ports that accept either Ethernet and Fibre Channel SFP+ modules. As such, the 6248UP can provide practically any distribution of Ethernet or Fibre Channel uplinks need to meet a customer?s design and bandwidth needs.

Announced at Cisco Live, the next wave of UCS hardware including a 48 port 1RU interconnect that takes 1Gbps, 10Gbps and soon 40Gbps ethernet, along with up to 8Gbps FC connections. UCS is future ready indeed.
