You have a fleet of servers, you will have bunches and bunches of Lantronix – that’s kind of a given.
I just started collocating, I have none. I do see them on amazon, but none from Lantronix which makes me wary to order any. And they are VGA only. I contacted them today, they said they don’t have any inventory, and will have two models out by August/October.
As for raritan, my experience is the opposite. It lags over great distances, which makes it unusable sometimes.
I am looking for a more up to date KVM with HDMI/DisplayPort support, and standalone.
