The IBM Flex System™ IB6132 2-port QDR InfiniBand Adapter delivers low-latency and high-bandwidth for applications in enterprise data centers, high-performance computing (HPC), and embedded environments. This adapter is designed to operate at InfiniBand QDR speeds (40 Gbps or 10 Gbps per lane). Clustered databases, parallelized applications, transactional services, and high-performance embedded I/O applications potentially achieve significant performance improvements, which helps reduce the completion time and lowers the cost per operation. The IBM Flex System IB6132 2-port QDR InfiniBand Adapter simplifies network deployment by consolidating clustering, communications, and management I/O. The adapter is based on Mellanox ConnectX-2 EN technology, which improves network performance by increasing available bandwidth to the CPU, especially in virtualized server environments.

Did you know?
This adapter is designed for low latency, high bandwidth, and computing efficiency for server and storage clustering applications. Combined with the IB6131 InfiniBand Switch, your organization can achieve efficient computing by off-loading from the CPU protocol processing and data movement overhead, such as RDMA and Send/Receive semantics, allowing more processor power for the application.

The IBM Flex System IB6132 2-port QDR InfiniBand Adapter with its ConnectX-2 controller has the features discussed in the following sections.
ConnectX-2 delivers low latency, high bandwidth, and computing efficiency for server and storage clustering applications. Efficient computing is achieved by offloading from the CPU routine activities, which makes more processor power available for the application. Network protocol processing and data movement impacts, such as InfiniBand RDMA and Send/Receive semantics, are completed in the adapter without CPU intervention. Graphical processing unit (GPU) communication acceleration provides additional efficiencies by eliminating unnecessary internal data copies, which significantly reduces application run time. The ConnectX-2 acceleration technology enables higher cluster efficiency and scalability of up to tens of thousands of nodes.
RDMA over converged Ethernet
ConnectX-2 utilizes the InfiniBand Trade Association's RDMA over Converged Ethernet (RoCE) technology to deliver similar low-latency and high-performance over Ethernet networks. Leveraging Data Center Bridging capabilities, RoCE provides efficient low-latency RDMA services over Layer 2 Ethernet. The RoCE software stack maintains existing and future compatibility with bandwidth and latency-sensitive applications. With link-level interoperability in the existing Ethernet infrastructure, network administrators can use existing data center fabric management solutions.
Applications utilizing TCP/UDP/IP transport can achieve industry leading throughput over InfiniBand or 10 GbE adapters. The hardware-based stateless offload engines in ConnectX-2 reduce the CPU impact of IP packet transport, allowing more processor cycles to work on the application.
ConnectX-2 with Virtual Intelligent Queuing (Virtual-IQ) technology provides dedicated adapter resources and guaranteed isolation and protection for virtual machines within the server. I/O virtualization with ConnectX-2 gives data center managers better server utilization and LAN and SAN unification while reducing cost, power, and cable complexity.
A consolidated compute and storage network achieves significant cost-performance advantages over multi-fabric networks. Standard block and file access protocols can use InfiniBand RDMA for high-performance storage access. T11-compliant encapsulation (FCoIB or FCoE) with full hardware offload simplifies the storage network while keeping existing Fibre Channel targets.
