ARM-based PDU for datacentre power management
nVent has developed an ARM-based low profile power distribution unit (PDU) for intelligent control of data centre power
The rack-mounted Smart RackPower PDU enables operators to control power in data cabinets, open frame racks and wall-mount enclosures.
The hot-swappable Network Management Controller (NMC) is based on an ARM Cortex A5 processor with options for top or bottom mounting as well as display rotation to maximise visibility of data. The MNC includes a USB-C port for future-proof upgrades and expanded sensor support, a Gigabit Ethernet primary network connection and 10/100 Ethernet for redundant networks, dual bandwidth access and high bandwidth cascading.
The PDU enables IP cascading with up to 64 PDUs accessed and managed using a single IP address. Cascading enables ease of management and maintenance as well as reducing cabling and connections. It is especially useful in situations where network resources are constrained, for example where IP addresses are in limited supply or external Ethernet ports are costly.
nVent, based in London, owns the CADDY, ERICO, HOFFMAN, RAYCHEM, SCHROFF and TRACER brands that are widely used for rack equipment throughout datacentres.
The PDU design has options for energy metering, outlet level switching and outlet level energy metering. Users can choose the features they need to optimise power at the rack level, from network management and access control, to remote power control at each individual outlet, customisable alarm thresholds and notifications, and high accuracy, billing grade metering to ISO/ IEC62053-21.
Other features include flexible and future proof 2-in-1 and 4-in-1 combo outlets, user defined electronic colour coding for easy power source identification, two-way DC power sharing for always-on network management and alarms, and extensive environmental monitoring and access control options with plug and play support for up to eight digital sensors.
With an operating range up to 60 degC, the new PDUs are suitable for increasingly power dense equipment racks in server rooms, data centres and harsh environments.
