I am working on a brand new IT room for around 4 high (12kw?) power racks and 2 wiring racks. I was talking to the obvious choice - Liebert - and they came back with a fairly eye watering quote that made me question whether they are the only game in town. During my research I fell across two companies - Rittal for cooling and Rittal's rebadge of Eaton technologies Powerware line of UPSes.
Rittal seem to have an extremely interesting product called the "LCP" which is a liquid cooled 11" wide blower unit that sits in between 2 racks and blows cold air across the faces of both adjoining racks. It then sucks the hot air from the back of the servers. It is able to operate in a variety of closed or open loop configurations - you can leave the faces of the racks open/meshed and blow cold air into the room, whilst leaving the backs of the racks closed/glass door to suck hot air in. If you need to go blade server crazy (30kW+ racks) you can go closed face front and back, and have a rittal unit on both sides of the rack. For those that are interested I found this PDF - http://www.equipmentprotectionmagazine.com/images/rittal-2.pdf. Reading between the lines it looks like around $11.5k for each unit, but I havent managed to get any real pricing out of them yet. On the power side, the Eaton Powerware 9390 (http://powerquality.eaton.com/Products-services/Backup-Power-UPS/9390.aspx) looks like a reasonable competitor to the Liebert NX UPS. Beyond that I have zero opinion on it. It seems like a good tool to beat Liebert over the head on pricing, but the reseller claims it is more efficient/moderner/betterer so maybe it is worth taking seriously. Curious to know if anyone has nice things to say about them. Anyway, wanted to throw the info out there in case people are interested. Would be interested to hear if anyone has strong opinions on either product, or warnings against them :-) Regards, Rob Cherry _______________________________________________ Discuss mailing list [email protected] http://lopsa.org/cgi-bin/mailman/listinfo/discuss This list provided by the League of Professional System Administrators http://lopsa.org/
