FWIW, I'm planning on getting a new receptacle put in for a NEMA 6-20 also at 240V (for efficiency compared to 120V).
I was looking at getting one or two of these: Tripp Lite PDU
EDIT: Also getting two UPS's. One for server / SAN stack, and another for Networking gear. You may want to look into an Automatic Transfer Switch for your network gear since they may not have redundant power supplies, unlike servers.
