I would agree - but I'm not really running a datacenter. I've got a
single rack. In said rack I've got a single 1U server. Below that on
a shelf I've got a single tower form factor computer acting as a
fileserver. Next to that I've got a UPS. Above the 1U mounted server
I've got a monitor, mouse, keyboard, and kvm.
I just needed a very cheap and dirty way to know if the temp spiked on
If, however, I ever add much hardware into this room, you can betcher
