The switch uplinks use SFP+ transceivers or Twinax cables

On June 29, HP announced the A5820, a top-of-rack (ToR) switch. Both the module and the switch take traffic from up to 16 blades (in a blade module) or rack servers (in a ToR switch), discern the type of packet (i.e., IP, Fibre Channel, or iSCSI), and send the appropriate packets to eight SFP+ uplinksfour 10GigE, two FC, and two BladeSystem interconnectsfor a true converged fabric coming from the servers.

In turn, the FC packets are forwarded on to an existing SAN for access to storage, and the IP packets are forwarded to the LAN. Each of the connections from the rack servers to the switch and the switch uplinks use SFP+ transceivers or Twinax cables.
