SUPPLEMENTAL MATERIAL
Network Connectivity
This section shows how the supported adapter card configurations for the B420 M4 connect to the Fabric
Extender modules in the 5108 blade server chassis.
There are three configurable adapter slots on the B420 M4. One slot supports only the VIC 1340/1240
adapter, and two additional slots accommodate Cisco adapters, as well as Cisco UCS Storage Accelerator
adapters.
Table 11 on page 22 and Table 12 on page 23 show supported adapter configurations. You must
install at least one VIC adapter in one of the three adapter slots.
Maximum bandwidth is a function of the Fabric Extender, the adapter, and the adapter slot, as shown in
Table 28.
Figure 11 shows the configuration for maximum bandwidth, where the following ports are routed to 8-port
Fabric Extender Modules A and B inside the 5108 blade server chassis:
■ 4 x 10 Gb KR ports from the VIC 1340/1240 adapter
■ 4 x 10 Gb KR ports from the Port Expander
■ 8 x 10 Gb KR ports from the VIC 1380/1280 adapter
■ 4 x 10 Gb from a Cisco Storage Accelerator when placed in adapter slot 2, similar to the
Cisco UCS Port Expander Card for VIC. Requires UCSM 2.2(4b) or later.
The resulting aggregate bandwidth is 160 Gb (80 Gb to each Fabric Extender).

Example Configuration to Achieve Maximum Bandwidth
2208XP 160 Gb Adapter 1 = VIC 1340/1240 (4 x 10 Gb)
Adapter 2 = Port Expander (4 x 10 Gb)
Adapter 3 = VIC 1380/1280 (8 x 10 Gb)
See Figure 16 on page 50
2204XP 80 Gb Adapter 1 = VIC 1340/1240 (2 x 10 Gb)
Adapter 2 = Port Expander (2 x 10 Gb)
Adapter 3 = VIC 1380/1280 (4 x 10 Gb)
