I have experience with a couple variations of this product: a 20-rack, back-to-back zone with a completely enclosed hot aisle and integral UPS, which has been operating for about a year (a second zone is planned for this year), and about to install a two-rack setup sharing a central RC unit, using the rear rack air containment panels. Planned density for the first project is 23 kW per rack and up to 9 kW per rack on the second.
I'd like to hear from anyone who is using APC or Liebert in-row units to supplement ambient cooling in traditional open hot aisle/cold aisle environments.
I'll be glad to answer any specific questions you have, if I can.
