Typical Configurations - Lenovo BladeCenter Virtual Fabric 10Gb Product Manual

Typical configurations

The BladeCenter Virtual Fabric 10Gb Switch Module can be used in various configurations. The following
usage scenarios are described:
10 Gb Ethernet Virtual Fabric
Converged iSCSI or FCoE network
10 Gb Ethernet Virtual Fabric
The Virtual Fabric 10Gb Switch Module UFP solution is based on a BladeCenter chassis with a 10 Gb
Converged Enhanced Ethernet (CEE) infrastructure and 10 Gb Virtual Fabric Adapters (VFAs) installed in
each blade server.
In UFP mode, the Virtual Fabric 10Gb Switch is vPort-aware; that is, the configuration of vPorts is
performed on a switch, then it propagates vPorts parameters to VFA. vPort bandwidth allocation and
metering is performed by the switch and the VFA. In such a case, a bidirectional virtual channel of an
assigned bandwidth is established between them for each vPort.
The Virtual Fabric 10Gb Switch is connected to top-of-rack aggregator switches, such as RackSwitch
G8272 via the 10 GbE external uplink connections. This scenario is illustrated in Figure 3.
