5.2 Powering InServ Storage Servers
The cabinets used to house the InServ Storage Server components are divided into power
domains where each contains a drive cage or controller node and two dedicated power
supplies. Drive cages and controller nodes depend on these two power supplies, located at the
rear of the system, to supply power from the Power Distribution Units (PDUs) that are located
at the bottom of the cabinet.
