10GigE Performance

Mellanox delivers industry-leading, cost-effective, high-performance 10-gigabit Ethernet interconnect solutions for mainstream grids and enterprise data centers. Virtualized server environments, high-volume data transactions and real-time technologies (such as VOIP and video on demand) increase the demands for higher bandwidth. Enterprise applications, such as CRM, data-warehousing, financial applications and web 2.0 applications  are demanding the leading I/O performance offered by Mellanox 10GigE adapters to optimize the data center productivity.
The dual-port ConnectX EN Ethernet adapter with PCIe Gen2 provides line-rate 10Gb/s bandwidth on both ports independently in both uni-directional and bi-directional modes. The ConnectX EN 10GigE supports standard TCP/IP and iSCSI protocol stacks provided by the operating system vendors like Microsoft, Redhat, Novell, VMWare and Citrix.

Basic Numbers
The preferred method for selecting the best interconnect is testing the target applications, and for that, Mellanox provide a cluster environment for application testing and benchmarking (click for more details).

The most common performance parameters used to compare between interconnects are latency and bandwidth. Mellanox ConnectX EN adapter is designed to provide the best price/performance for virtualization and IO consolidation applications in the data center.
