I recently upgraded my homelab core switch to a Mellanox SX 6012. It’s 12 ports of 40gb/s, and each can break out to 10gb/s. This switch also idles at 30 watts which was top of my list.
What model switches are you running, and do you like it?
Aruba S2500-48P. Picked up a used one for $130 on eBay 4 years ago, and it's been solid in my rack. 48 PoE 1GbE ports, and 4 10GbE SFP+ ports. At that price what more could you ask?!
