In a recent blog post from these pages, we discussed several situations in which you might consider using horizontal power distribution units in lieu of the more common vertical power distribution devices. Based on responses to our post, we decided to provide more feedback on going horizontal. We discussed several situations in our previous post that favor the use of the more compact horizontal PDU. Some of the reasons include distributing power from a rack-mounted UPS, or when you have space at the back of the rack left by shallow IT equipment such as those half-sized switches and routers. We also discussed situations in which additional air flow through the sides of the cabinet could be advantageous.
