The ThinkSystem QLogic QL41134 PCIe 10Gb 4-Port Base-T Ethernet Adapter is an advanced Quad-port 10GBASE-T Ethernet Adapter from Cavium which features Universal Remote Direct Memory Access (RDMA) to offer concurrent support for RoCE, RoCE v2, and iWARP. The adapter is suitable for customers wishing to use advanced technologies while still maintaining their investment in RJ45 copper wiring.
Enterprise-class virtualization
Enterprise-class data centers can be scaled using overlay networks to carry VM traffic over a logical tunnel using NVGRE, GRE, VXLAN, and GENEVE. Although overlay networks can resolve virtual Local Area Network (VLAN) limitations, native stateless offloading engines are bypassed, which places a higher load on the system's CPU. The Lenovo QL41134 Adapter efficiently handles this load with advanced NVGRE, GRE, VXLAN, and GENEVE stateless offload engines that access the overlay protocol headers. This access enables traditional stateless offloads of encapsulated traffic with native-level performance in the network.
High performance Universal RDMA Offload
The QL41134 Adapter supports RoCE and iWARP acceleration to deliver low latency, low CPU utilization, and high performance on Windows Server Message Block (SMB) Direct 3.0 and 3.02, Windows Server Storage Spaces Direct (S2D), and iSER. The QL41134 adapter has the unique capability to deliver Universal RDMA that enables RoCE, RoCEv2, and iWARP. Universal RDMA and emerging low latency I/O bus mechanisms such as Network File System over RDMA (NFSoRDMA) and Non-Volatile Memory Access Express over Fabric (NVMeoF) allow customers to accelerate access to data. Cavium's cutting-edge offloading technology increases cluster efficiency and scalability to many thousands of nodes.
Hyperscale Orchestration with OpenStack
The QL41134 adapter supports the OpenStack open source infrastructure for constructing and supervising public, private, and hybrid cloud computing platforms. It provides for both networking and storage services (block, file, and object) for iSER. These platforms allow providers to rapidly and horizontally scale VMs over their entire, diverse, and widely spread network architecture to meet the real-time needs of their customers. Cavium's integrated, multiprotocol management utility, QConvergeConsole (QCC), provides breakthrough features that allow customers to visualize the OpenStack-orchestrated data center using auto-discovery technology.
