Product Guide (withdrawn product)

The Mellanox 2-port 10Gb Ethernet Expansion Card (CFFh) for IBM® BladeCenter® delivers the industry’s lowest latency performance of 10 Gigabit Ethernet connectivity with stateless offloads for converged fabrics in enterprise data centers, high-performance computing, and embedded environments. Financial services, cluster databases, web infrastructure, and cloud computing are just a few example applications that will achieve significant throughput and latency improvements resulting in faster access, real-time response, and increased number of users per server. 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?
New enhancements such as Data Center Ethernet (DCE) are being added to Ethernet for better I/O consolidations. The InfiniBand Trade Association’s (IBTA) RDMA over Converged Ethernet (RoCE) technology provides efficient low- latency RDMA transport over Layer 2 Ethernet. The RoE software stack maintains existing and future application compatibility for bandwidth and latency- sensitive clustering applications. With link-level interoperability in existing Ethernet infrastructure, network administrators can leverage existing data center fabric management solutions with this adapter.

Features and benefits

The Mellanox 2-port 10Gb Ethernet Expansion Card (CFFh) has the features discussed below.

Performance

Based on ConnectX-2 EN technology, the Mellanox 2-port 10Gb Ethernet Expansion Card (CFFh) provides a high level of throughput performance for all network environments by removing I/O bottlenecks in mainstream servers that are limiting application performance. Blade servers in the BladeCenter H and HT chassis can fully utilize both 10 Gbps ports and achieve up to 40 Gbps duplex bandwidth. Hardware-based stateless offload engines handle the TCP/UDP/IP segmentation, reassembly, and checksum calculations that would otherwise burden the host processor. These offload technologies are fully compatible with Microsoft RSS and NetDMA.
RDMA over Converged Ethernet (RoCE) further accelerates application run time. RoCE specification provides efficient data transfer with very low latencies on lossless Ethernet networks. RoCE enables lowest latency memory transaction, with less than 2 µs at full bandwidth with small message size. This allows very high-volume transaction-intensive applications typical of financial market firms and other industries where speed of data delivery is paramount to take advantage. With the Mellanox 2-port 10Gb Ethernet Expansion Card (CFFh), high-frequency transaction applications are able to access trading information with shorter times, making sure that the trading servers are able to respond first to any new market data and market inefficiencies, while the higher throughput enables higher volume trading, maximizing liquidity and profitability.
In data mining or web crawl applications, RoCE provides the needed boost in performance to search faster by solving the network latency bottleneck associated with I/O cards and the corresponding transport technology in the cloud. Various other applications that benefit from RoCE with ConnectX-2 EN include Web 2.0 (Content Delivery Network), Business intelligence, database transactions, and various Cloud computing applications. Mellanox ConnectX-2 EN’s low-power consumption (less than 3.5 W per port) provides customers with high bandwidth and low latency at the lowest cost of ownership.

I/O virtualization
ConnectX-2 EN supports hardware-based I/O virtualization, providing dedicated adapter resources and guaranteed isolation and protection for virtual machines (VM) within the server. ConnectX-2 EN gives data center managers better server utilization and LAN and SAN unification while reducing costs, power, and complexity.

Quality of service
Resource allocation per application or per VM is provided by the advanced QoS supported by ConnectX-2 EN. Service levels for multiple traffic types can be based on IETF DiffServ or IEEE 802.1p/Q, along with the Data Center Bridging enhancements, allowing system administrators to prioritize traffic by application, virtual machine, or protocol. This powerful combination of QoS and prioritization provides the ultimate fine-grained control of traffic, ensuring that applications run smoothly in today’s complex environment.
