Equipment that requires a three-phase supply is almost by definition power hungry and mission critical at the same time. Such equipment ranges from blade chassis installed in 19" cabinets through to large freestanding mainframes. Although this equipment is likely to have its own on-board monitoring there is a great advantage, particularly in facility planning, in monitoring everything within the room in one place instead of half a dozen different software packages. With one tool it is possible to see where power is being used and how temperatures are affected at different times of the day at a whole room level or at individual cabinet or zone levels.
Intellidata Systems have developed a range of 3-phase monitoring products and software tools that simplify the task of installing 3 phase equipment in a fully monitored environment. In a typical blade chassis installation, each blade will require two 3-phase supplies arranged in the form of six IEC C19 (16 amp) sockets. For one or two blade chassis in a cabinet, the solution may be rack-mounting break-out boxes such as the Intelli3Phase dual. This unit takes two 3-phase feeds on 5-pin commandos and presents them on six individually monitored C19 outlets and (optionally) 5-pin commandos to daisy chain to the next break out. These boxes will complement the standard single phase zero-U strips used to supply other equipment in the rack.
In a high density cab where a greater quantity of 3-phase C19 outlets are required and rack space is at a premium, a 3-phase zero-U strip can deliver multiple sets of C19 3-phase outlets together with some additional C13 (10 amp) sockets for ancillary equipment. As with the rack-mounting solution, each C19 socket can be individually power monitored.
Standalone equipment such as mainframes may have no internalcapacity) that include temperature and humidity probes that can be remotely mounted within the monitored cabinet.
