Description

The UCS VIC 1440 is a modular LAN-on-motherboard (mLOM) virtual interface card from the Cisco UCS Virtual Interface Card 1400 Series. It is built for Cisco UCS B-Series M5 and M6 blade servers, where it replaces the standard mLOM and presents dynamically configurable PCIe NICs and HBAs to the host. It suits virtualised and large-scale VM deployments, big data and HPC workloads, and converged LAN and SAN connectivity over 10G and 40G fabrics.

The card provides a single 40-Gbps port, or 4x10-Gbps, carrying Ethernet and FCoE traffic over a PCIe 3.0 x16 host interface. With the optional port expander it provides two 40-Gbps Ethernet ports. It supports 256 virtual interfaces, draws up to 21 W from the blade's mLOM slot, and is managed through Cisco UCS Manager or Intersight. It is the mLOM option, as opposed to the VIC 1480 mezzanine card.

The VIC 1440 installs in B200 M5/M6 and B480 M5 blade servers and connects through UCS 2204, 2208, 2304 or 2408 IOMs, or the UCS 6324, to supported Fabric Interconnects. Pairing the card and port expander with an IOM 2408 delivers 40G aggregate with a maximum 25G single flow per vNIC, and needs UCSM 4.1(2a).

Features

- Stateless design: NIC and HBA count, MAC and WWN identity, failover, bandwidth and QoS are set by the service profile at boot
- Network interface virtualisation maps each PCIe interface to a fabric interconnect interface
- 256 dynamic virtual adapters and interfaces without requiring SR-IOV support from the OS or hypervisor
- Cisco SingleConnect carries LAN, SAN and management traffic over one unified network
- Hardware-based fabric failover provides a redundant path to the Fabric Interconnect
- Lossless Ethernet using Priority Flow Control
- Low-latency kernel bypass with usNIC and DPDK
- GENEVE, VXLAN and NVGRE stateless offloads, with VMQ/VMMQ and SR-IOV capability
- Storage protocols include FCoE, iSCSI boot, FC-NVMe and NVMeoF with RoCEv2

FAQs

Q: Which blade servers does the UCS VIC 1440 fit?
A: It installs in the mLOM slot of Cisco UCS B200 M5/M6 and B480 M5 blade servers.

Q: Does the VIC 1440 need a software licence?
A: The adapter itself has no licence listed. It is managed through Cisco UCS Manager or Intersight, which have their own licensing.

Q: How do I get two 40G ports from the VIC 1440?
A: Add the optional port expander. On its own the card provides a single 40-Gbps port, or 4x10-Gbps. With the port expander it provides two 40-Gbps Ethernet ports.

Q: What does it connect to?
A: It connects through UCS 2204, 2208, 2304 or 2408 IOMs, or the UCS 6324 in UCS Mini, to Fabric Interconnects including the 6248, 6296, 6332, 6454, 64108, 6536 and 6652.

Q: How does the VIC 1440 differ from the VIC 1480?
A: The VIC 1440 is an mLOM card installed in the blade's mLOM slot. The VIC 1480 (UCSB-VIC-M84-4P) is a mezzanine card.
