Equipment recommendations for remote reboot?

[Zembower, Kevin]

I've always had easy physical access to our small group of servers, but
the possibility exists that they'll be moved off-site in the next year
and difficult and time-consuming to access. My servers are very reliable
and typically have an uptime of more than 100 days. However, I do need
the capability to power them off (which I can do easily with 'shutdown
-h'), but most importantly, power them back on. What piece of equipment
to you all recommend to control power to a small (<8) number of Dell
PowerEdge (2450 and 2850) servers remotely?

Thank you for your suggestions and advice.
