Mellanox ConnectX-2 VPI Single-port and Dual-port QDR InfiniBand host channel adapters make it possible for any standard networking, clustering, storage, and management protocol to seamlessly operate over any converged network by using a consolidated software stack.

One year limited warranty. InfiniBand IB is a computer-networking communications standard used in high-performance computing that features very high throughput and very low latency.

Technical and de facto standards for wired computer buses.

Retrieved 13 September Retrieved from ” https: Supported servers The following table lists the ThinkSystem and Flex System compute nodes that support the adapters. The following terms are trademarks of Lenovo in the United States, other drd, or both: Resource allocation donnectx application or per VM is provided by the advanced quality of service QoS supported by ConnectX Updated the list of supported operating systems.

Part number information Features and benefits Specifications Physical specifications.

Efficient computing is achieved by offloading from the CPU routine activities, which makes more processor power available for the application. Physical specifications The dimensions and weight of the adapter are as follows: Operating system support may vary by server.


Links can be aggregated: At the time it was thought some of the more powerful computers were approaching the interconnect bottleneck of the PCI bus, in spite of upgrades like PCI-X. Storage accelerated A consolidated compute and storage network achieves significant cost-performance advantages over multi-fabric networks. Regulatory compliance The adapters conform to the following standards: Related product families Product families related to this document are the following: The following table shows the connections between adapters installed in the compute nodes to the switch bays in the chassis.
