Q:

After the S3900 switches are stacked, the device has lost the stacking port. What is the reason?

by h***n on 06/19/2020

A:

After the S3900 switch is successfully stacked and you check the port status through the commands, the two stacking ports of the device will disappear which is a normal situation. It is mainly to prevent misoperation.

Ive been using two of these for over a year now for a 64 node clusterthat occasionally has a collection of laptops and other spare computers added to it, getting as high as 78 nodes. The speed is excellent. I get great speeds between all nodesmost of which have a single gigabit, but some of which have two link aggregated gigabit connections even when the cluster is maxed, with massive internode communication going on. Not a single issue. Ive left these on for months at a time. My biggest compute job took over 2 weeks, and it was over 2 weeks of over 72 links working around the clock. They worked flawlessly. Theyve been very reliable for me, and very easy to administer.
