Each pair of adjacent connection blade slots forms a so-called fabric. The
following table shows how you can fill the fabrics and which network
components of the server blades they are connected to:
V CAUTION!
● The downlink ports of connection blades DCB SW 10Gb and FEX
B22F 10Gb (Cisco) operate only at 10 Gb link speed.
● The two connection blades within a fabric must have the same
technology, i.e. either Ethernet, Fibre Channel, SAS or Infiniband.
