Frequently Asked Questions
\What is the Mellanox SN2700 switch used for?
The SN2700 is a 32-port 100GbE datacenter switch designed for HPC, financial trading floors, and cloud spine-leaf architectures where ultra-low latency (<300 ns) and zero packet loss are critical.
Does the SN2700 support InfiniBand?
No. The SN2700 is an Ethernet-only switch based on the Spectrum-1 ASIC. For InfiniBand, look at the NVIDIA Quantum series (QM8700, QM9700).
Can SN2700 ports be split into 25GbE or 50GbE?
Yes. Each 100GbE QSFP28 port can be split into 2×50GbE or 4×25GbE using breakout cables, giving up to 128×25GbE ports total.
What operating systems run on the SN2700?
MLNX-OS and Cumulus Linux are officially supported. SONiC is also available as a community option.
