Whether it’s a metered PDU or a managed PDU (otherwise known as a switched PDU), you’ll need to determine what level of control your infrastructure power requires. Metered input PDUs offer branch-level metering, while metered outlet PDUs provide metering at individual outlets for billing-grade accuracy. For the most advanced capabilities, choose managed PDU technology that provides outlet-level switching (i.e. you can turn an individual outlet off and on remotely) and outlet-level monitoring, both of which help reinforce uptime for critical loads.
Look for models that include network connectivity, push button controls and a display screen.
If you’ve got just one or two racks and are looking for something simple, check out Eaton Basic PDUs.
Having enough electrical power to adequately supply your data center deployment is a big deal. When selecting an input cord and plug, research the amount of power it provides to the rack PDU along with the total power consumption of your IT equipment.
Don't forget to plan for growth and expansion. If you think your data center will grow, be sure that you’re considering power distribution to avoid designing yourself into a corner.
Don’t forget to double check that the length of the rack PDU line cord fits your space. If it’s too long, you’ll have extra cord to stuff into your rack enclosure. If it’s too short, you won’t be able to plug it in or you may be forced to position the rack PDU in a less than ideal location.
You can integrate temperature and humidity monitoring with your rack PDUs. With the Eaton Environmental Monitoring Probe (EMPs), you can daisy chain up to three EMPs to monitor the top, middle and bottom of your rack enclosures.
Physical security
Avoiding accidental disruptions and keeping unauthorized users out are keys to maintaining a safe data center environment. Look for rackmount PDUs that enable you to turn off unused outlets with outlet switching technology to control unauthorized use. Also, take advantage of integrated IEC outlet grips to prevent accidental disconnects that are typically caused by human error or over time by vibrating equipment.
Cyber security and monitoring
How will you manage your rack PDUs remotely, with multiple rows of equipment and/or multiple sites? Software solutions like Eaton's Distributed IT Performance Management software (DITPM), part of the Brightlayer Data Centers suite, provide deep intelligence into your network connected PDUs, enabling you to remotely manage and control your equipment, and identify and fix issues before your equipment goes down.
Basic PDU
A basic rack PDU provides reliable AC power distribution to multiple devices from a UPS system, generator or utility power source.
Local metered PDU
Local metered PDUs have digital load ammeters to enable local current monitoring, helping IT managers balance loads and prevent overloads. Select models also include premium Isobar® surge protection.
Monitored PDU
Monitored PDUs include the features of local metered PDUs, plus a network interface to support remote monitoring and control from virtually any location.
Switched PDU
Switched PDUs Include all monitored PDU features, plus local or remote control of individual outlets. A switched PDU helps the IT administrator eliminate costly site visits with the ability to remotely reboot malfunctioning devices and turn power off and on to each outlet.
Automatic transfer switch
An ATS (Auto transfer switch) PDU provides a redundant power option for single-corded network devices. If the primary source becomes unstable or fails, the ATS switches over to the secondary power source until the primary input is restored.
Hot-swappable PDU
Hot-swap PDUs include dual AC inputs and a manual transfer switch that allows maintenance, repair or replacement of compatible UPS systems without interrupting power to connected equipment.
Network switch/PDU combo units
Network switch/PDU combo units combine a managed or unmanaged gigabit ethernet switch with a network-grade PDU. The switch/PDU uses just 1U of rack space and is perfect for distributed networks where space is at a premium. Select models include Power over Ethernet (PoE) capabilities.
