40-port 200Gb/s InfiniBand switch

The NVIDIA MQM8700-HS2R is a rackmount switch delivering 200Gb/s per port across 40 QSFP56 interfaces. It provides non-blocking throughput of 16Tb/s and runs MLNX-OS on an x86 dual-core CPU with 8GB system memory. Two AC power supplies and a C2P airflow design support standard-depth rack installation.

Suited for high-density HPC and AI clusters

This switch fits environments that need 40 ports of 200Gb/s InfiniBand connectivity in a single 1U chassis with redundant power. It is not for buyers who require managed Layer 3 routing features, larger port counts, or different port speeds. Teams without InfiniBand cabling or those needing out-of-band management via a dedicated port should evaluate other options.

40 QSFP56 ports at 200Gb/s each

The decisive specification is the 40 QSFP56 ports operating at 200Gb/s, giving 16Tb/s aggregate bandwidth. Confirm that your servers and cables match the QSFP56 form factor and 200Gb/s signalling before purchase.

Questions about this item

Do I need QSFP56 transceivers and cables rated for 200Gb/s to use the 40 ports?

Yes, each of the 40 QSFP56 ports requires transceivers and cables that support 200Gb/s operation.

Can the 16Tb/s aggregate throughput handle traffic from older lower-speed InfiniBand devices?

The switch provides 40 non-blocking ports at 200Gb/s each; any device that plugs into a QSFP56 port will operate at its own rated speed within the 16Tb/s fabric.

How can I confirm the switch is forwarding at full 200Gb/s per port after installation?

Use the MLNX-OS CLI to check port counters and verify each active QSFP56 link shows 200Gb/s with zero errors.
