The Mellanox SX6015 is a compact 18-port SwitchX-2 FDR InfiniBand switch designed for high-performance computing, clustered storage, research labs, virtualization environments, and advanced homelab deployments.
Its eighteen QSFP ports support InfiniBand data rates up to FDR 56Gb/s per port and provide a dense low-latency fabric in a standard 1U rackmount chassis.
⚠️ Important SX6015 / MLNX-OS Management Notice
Mellanox hardware documentation identifies the SX6015 as an externally managed InfiniBand switch, while the closely related SX6018 is the internally managed 18-port model with dedicated management interfaces and MLNX-OS management. If the physical unit is being advertised as “SX6015 with MLNX-OS,” verify the exact chassis model, part number, front-panel management interfaces, and software state from the unit itself before purchase.

FAQ How many QSFP ports does the SX6015 provide?
It provides 18 QSFP InfiniBand ports.
What is the maximum port speed?
Up to FDR 56Gb/s per 4X port with compatible hardware and cabling.
Does SX6015 run MLNX-OS?
Mellanox hardware documentation identifies SX6015 as externally managed. SX6018 is the internally managed 18-port model associated with dedicated management interfaces and MLNX-OS. Verify the exact chassis before relying on MLNX-OS functionality.
Can the SX6015 operate as an Ethernet switch?
Mellanox documents externally managed SX6015 units as InfiniBand-only and not capable of Ethernet protocol operation.
Are QSFP cables included?
Only cables explicitly shown in the listing photos or stated are included.
Is this suitable for a homelab?
Yes, especially for advanced InfiniBand, HPC, clustered storage, and virtualization labs, provided compatible HCAs and cables are used.
