    Using a Horizontal vs. a Vertical Rack PDU

    Posted by RJ Tee on October 19, 2017

    While use of vertical PDUs, or vertical rack power distribution units, has become nearly ubiquitous in today’s data center, they are not the only game in town. Since we have been getting a lot of questions lately about Horizontal rack PDUs, we thought it would be useful to take moment to pause and reflect on our counterpart from the other axis. Besides orientation, the most obvious difference between the two rack mount power strips is that of space – outlet space to be exact. Since the typical horizontal PDU fills 1 to 2U gaps, the number of outlets available is limited to the width of the rack, or the number of U spaces you are willing to part with.
