Single-port HDR100/200 adapter

The DELL Mellanox ConnectX-6 SP HDR100/200 QSFP56 LP Adapter is a low-profile network card for Dell PowerEdge servers. It provides one QSFP56 port supporting HDR100 and HDR200 InfiniBand speeds. The card suits clusters needing high-throughput, low-latency fabric connectivity in a compact bracket. It fits 1U and dense compute nodes where full-height cards cannot be installed.

HDR100 and HDR200 headroom

A single port delivers 100 Gb/s or 200 Gb/s bandwidth for MPI traffic, storage fabrics and GPU-direct workloads. The adapter saturates one HDR link; multi-rail or multi-subnet designs need additional ports per node. Bandwidth scales linearly with each installed adapter, so total throughput depends on slot count and switch uplinks. Workloads requiring more than one concurrent HDR link per server will need extra adapters.

QSFP56 single-port constraint

The card exposes exactly one QSFP56 cage, so each server consumes one PCIe slot for one HDR link. Buyers needing two or more HDR ports per node must populate multiple slots or choose a dual-port model. Compatibility is limited to the listed PowerEdge C6520, C6525, C6615, C6620, R650, R650xs, R6515, R6525, R660, R660xs, R6615, R6625, R750, R750xa, R750xs, R7515, R7525, R760, R760xs, R7615, R7625 and XE8545 platforms.

Questions sur cet article

Will the ConnectX-6 SP HDR100/200 QSFP56 LP Adapter work with my existing Dell PowerEdge R750 server?

Yes, the adapter is listed as compatible with the Dell PowerEdge R750 among many other supported models.

How can I verify the adapter is operating correctly after installation?

The firmware has been updated and all components are tested; check the link status lights on the QSFP56 port and confirm the adapter appears in the server's PCIe device list.

Does the package include any cables or transceivers, or must I purchase them separately?

The listing describes the low-profile adapter only; QSFP56 cables or transceivers for HDR100/200 connectivity are not included and must be sourced separately.
