Lenovo Flex System CN 4054S 10Gb Virtual Fabric Adaptor
Flexible Bandwidth
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 8 virtual NIC (vNIC) devices per port (for a total of 16 vNICs) and the CN4054S can be divided in to 4 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.
Flex System CN 4054S 10Gb Virtual Fabric Adaptor
Supports multiple advanced protocols. Runs in physical, virtual, or switch-independent modes and helps reduce data center costs by using a common infrastructure for Ethernet and storage networks.
Build a Converged Infrastructure
- Multiprotocol support for 10 GbE
- Virtual NIC emulation
- Full hardware storage offloads
- Lenovo Features on Demand (not supported with ThinkSystem compute nodes)
- Emulex Virtual Network Acceleration (VNeX) technology support
- Advanced RDMA capabilities with RoCE v2
- High throughput and data acceleration on a standard Ethernet fabric, without the need for specialized infrastructure or management.
- Capability to deliver a 4x boost in small packet network performance vs. previous generation adapters, which is critical for transaction-heavy workloads
- Desktop-like experiences for VDI with up to 1.5 million FCoE or iSCSI I/O operations per second (IOPS)
- Ability to scale Microsoft SQL Server, Exchange, and SharePoint using SMB Direct optimized with RoCE
- More VDI desktops per server, due to up to 18% higher CPU effectiveness (the percentage of server CPU utilization for every 1 Mbps I/O throughput)
- Superior application performance for VMware hybrid cloud workloads, with up to 129% higher I/O throughput compared to adapters without offload
- Lenovo XClarity support
- Deploy faster and manage less when multiple Emulex Virtual Fabric adapters (VFAs) and Host Bus Adapters (HBAs) are combined
Did You Know?
The CN4054S and CN4052S are based on the new Emulex XE100-P2 "Skyhawk P2" ASIC, which enables better performance, especially with the new RDMA over Converged Ethernet v2 (RoCE v2) support. In addition, these adapters are supported by Lenovo XClarity Administrator, which allows you to deploy adapter settings easier and incorporate the adapters in configuration patterns.
The CN4052S adapter now supports 8 vNICs per port using UFP or vNIC2 and with adapter firmware 10.6. This means a total of 16 vNICs are supported. The CN4054S still supports 4 vNICs per port.
