HPE Flexible Slot (Flex Slot) Power Supplies share a common electrical and physical design that allows for hot plug, tool-less installation into HPE ProLiant Gen9 Performance servers. HPE's Flex Slot power supplies are certified for high-efficiency operation and offer multiple power output options, allowing users to "right-size" a power supply for specific server configurations. This flexibility helps to reduce power waste, lower overall energy costs, and avoid "trapped" power capacity in the data center. Flex Slot power supplies are rated for Platinum-level certification with efficiency of up to 94%, and Titanium-level certification with efficiency of up to 96%. Support for HPE Power Discovery Services, via embedded power line communication technology, is also available with the 800W Titanium and 1400W Platinum Plus model. 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. HPE Flexible Slot Battery Backup enables backup power in the same form factor as Flex Slot power supplies. The Battery Backup can provide up to 750W of power up to 60 seconds, or up to 500W when configured in paralleled configuration.
- Titanium-Certified Power Efficiency: Titanium (96%) power efficiency certification from 80Plus program – one of the highest power efficiency certifications available in the IT industry & Reduces data center operating costs related to power by reducing server power requirements and power waste.
- Flex Slot Design: Tool-less hot plug design improves serviceability buy allowing quick and easy access to system power supplies, Common form factor across all ProLiant Gen9 Performance series servers allows multiple server platforms to share power supply spares, reducing cost and space requirements for spares.
- Multiple Power Output 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, Support for both low-line and high-line AC input voltages providing additional flexibility to operate in multiple It environments (500W and 800W Platinum only). -48VDC, 277VAC and 380VDC input voltages are also available.
- Power Management: Supports multiple operating modes to maximize power efficiency when configuring servers with redundant power supplies, Integrated support for HPE's Power Discovery Services which communicates with the intelligent PDU to monitor and manage power usage (800W Titanium and 1400W Platinum Plus only).

HPE Power Discovery Services (PDS) combines the HPE Intelligent Power Distribution Unit (iPDU) and HPE Flex Slot Platinum Plus power supplies with HPE Insight Control software to create an automated, energy-aware network between IT systems and facilities.
HPE Power Discovery Services Features and Benefits : Captures highly accurate power data across racks and rows of servers in order to identify and eliminate areas of waste, Extends the life of the data center by reclaiming up to 3x energy capacity of the data center, Ensures uptime by eliminating human error during power planning and provisioning

How Is PDS enabled by Flex Slot Platinum Plus or Flex Slot Titanium Power Supplies?
HPE Flex Slot Titanium Power Supplies and HPE Flex Slot Platinum Plus Power Supplies include an embedded power line communication feature that allows the power supply to communicate server data (such as name, UUID, and IP address) to an HPE Intelligent Power Distribution Unit (iPDU). This feature is supported on all HPE ProLiant Gen9 servers that support HPE Flex Slot Titanium Power Supplies and HPE Flex Slot Platinum Plus power supplies.
-
An HPE ProLiant Gen9 server configured with 2 Flex Slot Power Supplies – 500W, 800W, or 1400W - supports the following three power scenarios: Operation with a single power supply, Operation with redundant power supplies in load-balanced mode, Operation with redundant power supplies in high-efficiency mode, A single Flex 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 Flex Slot Power Supplies operating in load-balanced mode (the default mode when adding redundant power supplies), the load is shared equally between the two 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.
-
HPE Flex Slot power supplies are compatible with all HPE ProLiant Gen9 Performance servers including the: HPE ProLiant DL360 Gen9, HPE ProLiant DL380 Gen9, HPE ProLiant ML350 Gen9.
