0U and 1U Switched and Monitored PDUs

The 0U and 1U Switched and Monitored Power Distribution Units (PDUs) are the ideal solutions when you need flexible, reliable, easy-to-deploy power distribution with branch circuit protection to minimize downtime. These rack- dense units distribute power to up to 24 outlets in a 0U configuration and 12 outlets in a 1U configuration.
The 0U and 1U PDUs can be used separately or in combination with other Lenovo, PDUs to provide from a few outlets up to a full rack, scaling as required or as business needs change to support even greater power densities.

Introduction to PDUs

A power distribution unit (PDU) is a highly reliable, multiple outlet power strip designed to consolidate line cords within the rack and distribute conditioned power from an uninterruptible power supply (UPS) or utility power to servers and other IT equipment. The PDU efficiently distributes power within the rack and provides fault-tolerant power redundancy for high availability requirements.
There are three types of PDUs available from Lenovo: basic, monitored and switched and monitored. The PDUs covered in this document is of the switched and monitored type.

Basic: The simplest and most cost-effective power distribution. Available with various outlet configurations and line cord options to support different systems and load requirements.
Monitored (also known as PDU+): provides the same benefits as a Basic PDU, but adds additional advanced PDU power monitoring down to the load group. This enables businesses to have a cross-platform rack-level power and thermal view for trending analysis to improve power management.
Switched and monitored: These are advanced power management solutions, providing power monitoring at the outlet level, with increased accuracy at low amperages, for more precise views of power consumption down to the individual server level instead of at the consolidated load group. These PDUs also offer individual outlet switching (on/off), which allows for remote power sequencing and helps prevent unintended PDU overloading. Management can be performed through a web-based interface or by tools such as IBM Systems Director Active Energy Manager™.

Systems Director Active Energy Manager (AEM)

AEM provides an array of new features that allow power and thermal trending analysis for improved power management. AEM collects power information for each device attached to a Switched and Monitored PDU, presenting a more complete view of energy usage within the data center.
The AEM helps in the following ways:

Collect power information from each device attached to a Switched and Monitored PDU, thus presenting a more complete view of energy usage.
Server consolidation plans, because of increased server and rack power densities have driven the requirement for advanced power management solutions.
In combination with the optional Environmental Monitoring Probe, AEM enables cross-platform power and thermal trending analysis for improved power management. This configuration allows IT and facility managers to manage data centers for optimal energy efficiency, migrate workloads to eliminate hot spots, and transfer work from underutilized systems to conserve energy.
