What are the port configurations of the Dell M4001 switches?

The M4001Q and M4001F feature 32 non-blocking ports: 16 internal ports dedicated to server blades and 16 external QSFP+ ports. These support full copper and fiber cabling, delivering QDR 40Gb/s or FDR 56Gb/s per port with 3.584Tb/s total switching capacity.

What is the latency performance?

Port-to-port latency is 170ns, enabling low-delay access for each blade. This is enhanced by 9 virtual lanes (8 data + 1 management), congestion control, adaptive routing, QoS, and port mirroring for optimal traffic management in high-performance fabrics.

Which chassis are these switches compatible with?

Designed as blade switch modules for Dell PowerEdge M1000e-series enclosures. They provide full connectivity across the chassis with 16 internal ports fixed to blades, occupying a single slot for redundancy options.

What speeds do the M4001Q and M4001F support?

M4001Q offers QDR 40Gb/s per port; M4001F provides FDR up to 56Gb/s per port. Both are IBTA 1.21 and 1.3 compliant, with MTU sizes from 256 to 4Kbyte for scale-out computing and cloud environments.

What is the power consumption profile?

M4001Q consumes 60W typical and 75W maximum; M4001F has a similar profile. This low-power design suits dense datacenter deployments, operating from 0 to 40°C with RoHS-6 compliance.

What management features are included?

Supports congestion control, adaptive routing, QoS, port mirroring, and IBTA management via OpenSM or third-party subnet managers. Includes per-port status LEDs and system indicators for easy monitoring in enterprise fabrics.
