Cisco UCS B-Series Blade Server connectivity
-
Cisco UCS B-Series Blade Servers contain half-width or full-width blades with third or fourth-generation Cisco UCS VICs on M4 and M5 servers.
Half-width blades
Half-width, M4 Cisco UCS B-Series Blade Servers can contain a third-generation Cisco UCS VIC 1340. Half-width M5 servers can contain a fourth-generation Cisco UCS VIC 1440 in the motherboard (mLOM) mezzanine slot.
The third-generation Cisco UCS VIC 1380 M4 or M5 servers and the fourth-generation Cisco UCS VIC 1480 M5 servers can be installed in the PCIe mezzanine slot. The slot is next to the Cisco UCS VIC 1340 or Cisco UCS VIC 1440. Both VICs can direct nonmanagement network traffic to a separate physical adapter.
All of the VICs can connect at 20 Gbps to each fabric. The Cisco UCS VIC 1340 or Cisco UCS VIC 1440 can be installed with a port expander card for native 40 Gbps connectivity to each fabric. The Cisco UCS VIC 1440 supports a port expander with a Cisco UCS 2304 Fabric Extender IOM. The VIC 1440 does not support port expanders with Cisco UCS 2408, 2204XP and 2208XP IOMs.
Full-width blades
Full-width, M4 Cisco UCS B-Series Blade Servers can be configured with a Cisco UCS VIC 1340, or a Cisco UCS 1340 and Cisco UCS 1380. Full-width, M5 Cisco UCS B-Series Blade Servers can contain a Cisco UCS VIC 1440 and Cisco UCS VIC 1480.
The Cisco UCS VIC 1340 and 1440 can connect at 20 Gbps. The Cisco UCS VIC 1380 and 1480 can communicate at a maximum bandwidth of 40 Gbps to each fabric. You can configure the full-width blade server to contain a Cisco UCS VIC 1340 or 1440, a port expander, and a Cisco UCS VIC 1380 or 1480 to communicate at a maximum bandwidth of 40 Gbps per fabric. The Cisco UCS VIC 1440 supports a port expander with a Cisco UCS 2304 Fabric Expander IOM. The Cisco UCS VIC 1440 does not support port expanders with Cisco UCS 2408, 2204XP and 2208XP IOMs.
Each Cisco UCS B-Series Blade Server connects to the Cisco UCS 2304 Fabric Extender IOM through the Cisco UCS 5108 Blade Server Chassis at the mid-plane. Each IOM carries converged network traffic through two or four 40 Gbps links to the FI.
