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.
