The Chinese made ones are even cheaper, open up a TP-Link "desktop 8 port Gigabit Switch" and you will find the current "leader" in that market. Those datasheets though will be in Chinese so it helps to be able to read Chinese. (various translate apps are not well suited to datasheets in my experience)
- sitkack 4y agoThank you. Yeah, I found the ones on mouser and digikey. $20 is a bit much (not for a one off, but if you are aggregating low end processors you will need a lot of them). I'd love something like a 12-20 port 1Ge with a 10Ge uplink. If you find a super cheap 1Ge switch chip and docs (I suppose you could just reverse engineer the pcb from a tp-link switch), please post it.
- ChuckMcM 4y agoNo worries, the key though is cross section bandwidth. The "super cheap" GbE switch chips can have as little as 2.5 GBPS of cross section bandwidth which makes them ill suited for cluster operations.
