i'm reaching the point where i have a significant number of servers at my
colo facility. it has become evident that i could use two things:
1. a way to access multiple hosts via serial, that way i can communicate
with them even when networking fails, or i iptables myself out by mistake,
or sshd dies, etc. something that takes up only 1u of space, can provide
serial access to ~16 machines, and accepts ssh connections. the other
option is an IP kvm switch but that seems like a clunky alternative.
2. a way to power cycle hardware in a worst case scenario. something like
an intelligent power strip that can be accessed via ssh or serial that allow
individual control of outlets.
i know these devices exist, i just don't have any firsthand experience with
them to know what works well and what doesn't. any suggestions or
recommendations would be welcome.
