Features

The ThinkSystem QLogic QL41262 10/25GbE SFP28 2-Port PCIe Ethernet Adapter has the following key features:

Cost effective single-lane connection

The 25 Gbps Ethernet specification enables network bandwidth to be cost-effectively scaled in support of next-generation server and storage solutions residing in cloud and Web-scale data center environments. 25GbE results in a single-lane connection similar to existing 10GbE technology—but it delivers 2.5 times greater bandwidth. Compared to 40GbE solutions, 25GbE technology provides superior switch port density by requiring just a single lane (versus four lanes with 40GbE), along with lower costs and power requirements. Cavium is a leading innovator driving 25GbE technologies across enterprise and cloud market segments.

High performance Universal RDMA Offload

The Lenovo QL41262 Adapter supports RoCE and iWARP acceleration to deliver low latency, low CPU utilization, and high performance on iSER and Windows Server Message Block (SMB) Direct 3.0 / 3.02. QL41262 25GbE adapters have the unique capability to deliver Universal RDMA that enables RoCE, RoCEv2, and iWARP. Cavium Universal RDMA and emerging low latency I/O bus mechanisms such as Network File System over RDMA (NFSoRDMA) and Non-Volatile Memory Express (NVMe) allow customers to accelerate access to data. Cavium’s cutting-edge offloading technology increases cluster efficiency and scalability to many thousands of nodes.

High density server virtualization

The latest hypervisors and multicore systems use several technologies to increase the scale of virtualization. The Lenovo QL41262 Adapter supports:

  • VMware NetQueue
  • Windows Hyper-V Virtual Machine Queue (VMQ)
  • Linux Multiqueue
  • Windows, Linux, and VMware switch-independent NIC partitioning (NPAR)
  • Windows Hyper-V, Linux Kernel-based Virtual Machine (KVM), and VMware ESXi SR-IOV

These features provide ultimate flexibility, quality of service (QoS), and optimized host and virtual machine (VM) performance while providing full 25Gbps bandwidth per port. Public and private cloud virtualized server farms can now achieve 2.5 times the VM density for the best price and VM ratio.

Wire-speed network 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 QL41262 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. Additionally, the QL41262 25GbE adapter supports VMware NSX and Open vSwitch (OVS).

Hyperscale Orchestration With OpenStack

The Lenovo QL41262 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.

Accelerate NFV workloads

In addition to OpenStack, the Lenovo QL41262 Adapter supports Network Function Virtualization (NFV) that allows decoupling of network functions and services from dedicated hardware (such as routers, firewalls, and load balancers) into hosted VMs. NFV enables network administrators to flexibly create network functions and services as they need them, reducing capital expenditure and operating expenses, and enhancing business and network services agility. Cavium 25GbE technology is integrated into the Data Plane Development Kit (DPDK) and can deliver up to 60 million packets per second to host the most demanding NFV workloads.

FCoE and iSCSI storage offloads

The Lenovo QL41262 Adapter supports a hardware offload engine that accelerates FCoE and iSCSI storage protocol processing and enables the server CPUs to focus on applications, thereby improving the server’s overall performance.
