Please let us know how do we connect SN 2100 P/N: SN2100-BB2F (40Gbps switch with QSFP28 ports) with dual port 25Gbps LAN card ? How do we stack 02 nos of SN2100 switches using DAC cables to configure it as single virtual switch for HA ?

Hello Chintan,

Thank you for posting your inquiry on the NVIDIA Networking Community.

Based on the information provided, you can connect the SN2100 to a 25GbE adapter with a SFP28 cable suitable for your adapter → https://www.mellanox.com/related-docs/prod_cables/PB_MCP2M00-Axxx_25GbE_SFP28_DAC.pdf

Unfortunately, our switches are not able to be stacked as one switch. However you can connect/configure them into a MLAG (Multi-Chassis LAG) which provides redundancy. Please review the following link regarding MLAG and how-to implement → https://community.mellanox.com/s/article/how-to-configure-mlag-on-mellanox-switches

Thank you and regards,
