Introduction
The CN4054S 4-port and CN4052S 2-port 10Gb Virtual Fabric Adapters are VFA5.2 adapters that are supported on ThinkSystem and Flex System compute nodes.
The CN4052S can be divided into up to eight virtual NIC (vNIC) devices per port (for a total of 16 vNICs) and the CN4054S can be divided in to four vNICs (for a total of 16 vNICs). Each vNIC can have flexible bandwidth allocation. These adapters also feature RDMA over Converged Ethernet (RoCE) capability, and support iSCSI, and FCoE protocols, either as standard or with the addition of a Features on Demand (FoD) license upgrade.
Features
- The CN4054S 4-port 10Gb Virtual Fabric Adapter and CN4052S 2-port 10Gb Virtual Fabric Adapter, which are part of the VFA5.2 family of System x and Flex System adapters, reduce cost by enabling a converged infrastructure and improve performance with powerful offload engines. The adapters have the following features and benefits:
- Multiprotocol support for 10 GbE
- The adapters offer two (CN4052S) or four (CN4054S) 10 GbE connections and are cost- and performance-optimized for integrated and converged infrastructures. They offer a “triple play” of converged data, storage, and low latency RDMA networking on a common Ethernet fabric. The adapters provides customers with a flexible storage protocol option for running heterogeneous workloads on their increasingly converged infrastructures.
Virtual NIC emulation
- The Emulex VFA5.2 family supports three NIC virtualization modes as standard: Virtual Fabric mode (vNIC1), switch independent mode (vNIC2), and Unified Fabric Port (UFP). With NIC virtualization, each of the physical ports on the adapter can be logically configured to emulate up to four or eight virtual NIC (vNIC) functions with user-definable bandwidth settings. With UFP or vNIC2, the CN4052S supports eight vNICs per port. Both adapters support four vNICs per port with vNIC1 and vNIC2. Additionally, each physical port can simultaneously support a storage protocol (FCoE or iSCSI).
