ConnectX-6 SP HDR100/200 InfiniBand Adapter

This single-port ConnectX-6 SP adapter delivers HDR100 and HDR200 InfiniBand performance through a QSFP56 interface. It targets high-performance computing clusters and storage fabrics that require low-latency, high-bandwidth interconnects. The card fits full-height PCIe slots in compatible Dell PowerEdge servers.

QSFP56 full-height design for rack servers

The full-height bracket matches standard rack-mount PowerEdge chassis such as the R650, R6525, R660, R6615, R6625, R750, R750xa, R7515, R7525, R760, R760xa, R7615, R7625 and XE8545. A single QSFP56 port supports direct-attach copper or optical cables for flexible rack cabling. Firmware is updated and components are tested before shipment.

Upgrades from earlier HDR or EDR single-port cards

Sites moving from older HDR100 or EDR single-port adapters gain the higher 200 Gb/s lane rate without changing cable infrastructure. The jump is worthwhile when workloads saturate 100 Gb/s links or when cluster expansion demands the extra headroom. It does not suit builds that need dual-port redundancy or PCIe x8 electrical width.
