As wattages increase in high-density server racks, providing redundant
power becomes more challenging and costly. Traditionally, the most
practical solution for distributing redundant power in 208V server racks
above 5 kW has been to connect dual 3-phase rack PDUs to dual power
supplies in each server. Although this approach is reliable, it negates a
rewarding system design opportunity for clustered server applications.
With their inherent resilience and automated failover, high-availability
server clusters will still operate reliably with a single power supply in
each server instead of dual power supplies. This streamlined system
design promises to reduce both capital expenditures and operating
costs, potentially saving thousands of dollars per rack.
The problem is that dual rack PDUs can’t distribute redundant power
to a single power supply. An alternative approach is to replace the dual
PDUs with an automatic transfer switch (ATS) connected to a single PDU,
but perfecting an ATS tha
This white paper explores the challenges of increasing computing power in resource-constrained physical spaces and data centers experiencing high growth. We also explore how intelligent rack PDUs can meet these challenges and address critical uptime and capacity planning issues.
This Case Study explores how they installed energy management software and intelligent rack PDUs with outlet-level power monitoring to add remote energy management, power monitoring of individual devices, environmental monitoring, and sophisticated and accurate power usage reports and analytics.
Increased processing needs means increased energy costs. In fact, power costs can often exceed hardware costs. Read this white paper and see how the pairing of new IBM System x and BladeCenter servers with the new Intel Xeon Processor 5500 series can reduce costs and improve performance.

Traditionally, the most practical solution for distributing redundant power to 208V server racks above 5 kW has been to connect dual 3-phase rack PDUs to dual power supplies in each server. Although this approach is reliable, there is a better way. Tripp Lite has developed a patent-pending high-capacity 3-phase rack ATS specifically designed to deliver efficient, reliable redundant power to high-density clustered server environments.
This White Paper will:
• Explain the redundancy challenges for high-density server racks
• Compare traditional dual PDU and 3-phase rack ATS redundancy setups
• Outline the benefits of using a Tripp Lite 3-phase rack ATS
Power distribution units (PDUs) are vital to the management of power to IT arrays and have evolved from a simple panel of switches and outlets to designs that can now be considered "intelligent" through the inclusion of internal processing capabilities.
