Refurbished HPE Common Slot (CS) Power Supplies share a common electrical and physical design that allows for hot-swap, tool-less installation into HPE server and storage solutions. The Hewlett Packard Enterprise CS power supplies offer high-efficiency power options available in multiple input and output options, allowing users to "right-size" a power supply for specific server/storage configurations and environments. This flexibility helps to minimize power waste, lower overall energy costs, and avoid "trapped" power capacity in the data center.
High efficiency options rated for up to 94% (Platinum/Platinum Plus) and up to 96% (Titanium) power efficiency are available in the Common Slot form factor. Most options also support HPE Power Discovery Services via embedded power line communication (PLC) technology. This feature enables each server to communicate identification, location, and power-related data to the Intelligent Power Distribution Unit in the rack which can then be shared with HPE Insight Control to manage power usage and efficiency in the data center.
Common Slot Design: Tool-less hot-swap design allows for quick and easy access to power supplies, Wide range of compatibility across HPE server and storage solutions minimizes the cost and management effort to maintain different sets of power supply spares.
Multiple Output and Input Options: Multiple output options allowing users to "right-size" their power needs and avoid "trapped" power capacity in their data centers caused by over-subscribing power needs, Both AC and DC power input options available providing flexibility to operate in different IT environments, Most Common Slot AC power supply options support both low-line and high-line voltage inputs providing additional flexibility to operate in multiple It environments.
Power Management for Redundant Power Configurations: Supports multiple operating modes to maximize power efficiency when configuring servers and storage with redundant power supplies, Load-Balancing mode designed to maximize power efficiency at higher power supply utilization loads, High-Efficiency mode designed to maximize power efficiency at lower power supply utilization loads.
Highest Rated Power Efficiency: Titanium (96%) and Platinum (94%) power efficiency certification from 80Plus program - highest certifications available in the IT industry, Minimize data center operating costs related to power by reducing power waste and requirements for HPE server and storage solutions
Supports the Hewlett Packard Enterprise Power Discovery Services (on most options): Creates energy-aware network through embedded power line communication feature in Platinum power options, Communicates power-related data to both iPDU and HPE Insight Manager, Reduces human error, reclaims over-provisioned power capacity, and accurately measures/monitors power usage.
- An HPE ProLiant server configured with an HPE Common Slot VAC Power Supply (460W, 750W, 1200W, or 1500W) supports the following three power scenarios: Operating with a single supply, Operating with redundant supplies in load-balanced mode, Operating with redundant supplies in high-efficiency mode.
- A single Common Slot Power Supply supporting the entire load of the server can achieve the highest efficiency when operating in the middle range (50%) of its capacity.
- For redundant Common Slot Power Supplies operating in load-balanced mode (the default mode when adding redundant power supplies), the load is shared equally between the two (or four) power supplies. In general, the load-balanced mode offers better efficiency for loads requiring more than 60 percent of the primary power supply capacity.
- When high-efficiency mode is enabled for redundant supplies (via the server's ROM-based setup utility under System options -> Redundancy options), each power supply in the server is designated as either a primary or secondary supply, and the entire server load is shifted to the primary power supply. This allows the primary power supply to operate at higher efficiency points on the load curve while the secondary power supply operates in idle mode, providing no output power and consuming very little energy (typically two to four watts per supply). The user can also specify that odd or even power supplies will be designated manually or automatically as secondary supplies. This flexibility allows users to balance the load across a rack manually or automatically.
