HP have just released their MDS cooled racks. I've requested a quote from our suppliers today, will post when i get a figure.
A well designed room with good airflow won't necessarily need cooled racks unless you're fully populating. Also bear in mind that your ambient A/C needs to be able to cope with the failure of a rack cooling unit. Don't skimp on ambient AC just because your racks suddenly become temperature neutral.

Thanks so much for the replys.
To cut a long story short we have an empty room with a air extract point in the ceiling. Once we've put power in there and fire suppression we were going to install the usual a/c units that we use (Airdale units that blow conditioned air underneath the floor to cool the room)
Installing these a/c units has some fairly large cost coupled to it and I've been asked to explore if we can use something like what we've discussed above.
As you can probably guess I'm not in IT, however I am responsible for the facility's so therefore the exploration of this idea falls at my feet.

depends what you're actually putting in this room, but if it's anything more than a pretty small office set up, you really need aircon in the room. These racks generally have a fan to circulate air, but you need to make sure that you cool the air down - especially if using blade servers, as they put out loads of heat.
Again, depends how important it is / how much money the business loses if there is any downtime, but I wouldn't put my kit in an un-a/c room.

Guydw,
The point is about the XDF racks is that they have cooling function built into them (it's like a big, clever, expensive fridge!)
I'm still yet to establish the cost of these things but I can imagine it's going to be a few quid!

The heat has to go somewhere, and these racks just pump it out the top into the room. Where did you think the heat was going to go? Phil,
I agree and that's why I said earlier about the room having an air extract point in the ceiling as we obviously have to get rid of the hot air once the cabinet has expelled it.
I was just after some real-life experience from people if they had used them before.
Thanks
John

Sorry John, don't know how I missed that bit! We had something similar in our last place, and to be honest the server guys thought they were a waste of time. I'll find out more and get back to you.

Thank you sir!

The heat has to go somewhere, and these racks just pump it out the top into the room. Where did you think the heat was going to go? The HP MCS kit is water cooled, so claims to be temperature neutral. Looks very impressive from the docs on their website.
