– Software compatible with standard TCP/
UDP/IP and iSCSI stacks
ConnectX-2 EN Ethernet Network Interface Cards (NIC) deliver high-bandwidth and industry-
leading 10GigE connectivity with stateless ofoads for converged fabrics in High-Performance
Computing, Enterprise Data Centers, and Embedded environments. Clustered databases,
web infrastructure, and IP video servers are just a few example applications that will achieve
signicant throughput and latency improvements resulting in faster access, real time response
and increased number of users per server. ConnectX-2 EN improves network performance by
increasing available bandwidth to the CPU and providing enhanced performance, especially in
virtualized server environments.
ConnectX-2 EN protects investments by providing in hardware support for Data Center Bridging
(DCB) and Fibre Channel over Ethernet (FCoE) as well as technologies such as SR-IOV that provide
enhanced virtual machine performance for virtualized servers.
Optimal Price/Performance
ConnectX-2 EN removes I/O bottlenecks in mainstream servers that are limiting application
performance. Servers supporting PCI Express 2.0 with 5GT/s will be able to fully utilize both
10Gb/s ports, balancing the I/O requirement of these high-end servers. Hardware-based stateless
ofoad engines handle the TCP/UDP/IP segmentation, reassembly, and checksum calculations
that would otherwise burden the host. Stateless ofoad connections are also easy to scale using
multiple adapters to reach the desired level of performance and fault tolerance. Total cost of
ownership is optimized by maintaining an end-to-end Ethernet network on existing operating
systems and applications.
Mellanox provides 10GigE adapters suitable for all network environments. The dual port SFP+
adapter supports 10GBASE-SR, -LR, and direct attached copper cable providing the exibility to
connect over short, medium, and long distances. The dual port 10GBASE-CX4 adapter with its
powered connectors can utilize active copper and ber cables as well as passive copper.
Converged Ethernet
ConnectX-2 EN delivers the features needed for a converged network with support for Data
Center Bridging (DCB). T11 compliant FCoE support with full hardware ofoads simplies the
storage network while keeping existing Fibre Channel targets. RDMA over Ethernet (RoE), utilizing
IBTA RDMA over Converged Ethernet (RoCE) technology, provides efcient, low latency, RDMA
transport over Layer 2 Ethernet. The RoE software stack maintains existing and future compat-
ibility with bandwidth and latency sensitive applications. By maintaining link-level interoperability
with existing Ethernet networks, IT managers can leverage
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 unication while
reducing costs, power, and complexity.
