Dell™ PowerEdge™ R710 Technical Guidebook

Section 4. Power, Thermal, Acoustic

A. Power Efficiencies

One of the main features of the 11th generation of PowerEdge servers is enhanced power efficiency. PowerEdge R710 achieves higher power efficiency by implementing the following features:

User-selectable power cap (subsystems will throttle to maintain the specified power cap)

Improved power budgeting

Accurate inlet temperature

PSU / VR efficiency improvements

Switching regulators instead of linear regulators

Closed loop thermal throttling

Increased rear venting / 3D venting

PWM fans with an increased number of fan zones and configuration-dependent fan speeds

Use of DDR3 memory (lower voltage compared to DDR2, UDIMM support)

CPU VR dynamic phase shedding

Memory VR static phase shedding

Random time interval for system start

Allows an entire rack to power on without exceeding the available power

BIOS Power/Performance options page

Active Power Controller (BIOS-based CPU P-state manager)

Ability to power down or throttle memory

Ability to disable a CPU core

Ability to turn off LOMs or PCIe lanes when not being used

Option to run PCIe at Gen1 speeds instead of Gen2

B. Power Supplies

I. Main Power Supply

The base redundant system consists of two hot-plug 570W Energy Smart (energy efficient) power supplies in a 1+1 configuration. An 870W high-output power supply is also available. The power supplies connect directly to the planar.

There is a power cable to connect between the planar and the backplane. PowerEdge R710 power supplies have embedded cooling fans.

Starting with the 11th generation of PowerEdge servers (R710, R610, T610, M610, and M710), the power supplies no longer have a FRU EEPROM. FRU data is now stored in the memory of the PSU Microcontroller. Additionally, the PSU Firmware can now be updated by the BMC over the PMBus. Power is “soft-switched,” allowing power cycling via a switch on the front of the system enclosure, or via software control (through server management functions). In a single power supply configuration, the power supply is installed in the PS1 location and a blank module (metal cover) is installed in the PS2 location for factory consistency. Electrically, the system can operate with a single power supply in either bay.

The server can accommodate up to 128GB of DDR3 RAM across its 16 DIMM slots, delivering the memory capacity needed for demanding applications while also providing the performance enhancements of higher memory speeds.

The R710 also boasts an impressive array of storage options. It supports up to eight 2.5-inch or six 3.5-inch hard drives, which can be configured in various RAID levels for enhanced data protection and performance. The server is compatible with both SAS and SATA drives, providing flexibility for different storage needs. Additionally, the optional PERC (PowerEdge RAID Controller) allows for enhanced RAID configurations, ensuring data integrity and performance optimization.

In terms of connectivity, the Dell R710 comes equipped with four Gigabit Ethernet ports for high-speed networking. This connectivity facilitates effective communication in virtualized and clustered environments. The server is also built with optional iDRAC (Integrated Dell Remote Access Controller) technology, which provides administrators with advanced management capabilities, remote control, and monitoring features that simplify server administration, minimize downtime, and enhance overall productivity.

Thermal efficiency is another key characteristic of the R710. Its innovative cooling design features intelligent fans that optimize airflow based on workload demands, ensuring that the system runs at optimal temperatures while minimizing energy consumption. This contributes to reduced operating costs and a smaller environmental footprint.

The modular design of the R710 allows for easy upgrades and maintenance, making it a practical option for IT departments. The server’s support for various operating systems, including Windows Server and various distributions of Linux, ensures compatibility with diverse environments.

In summary, the Dell PowerEdge R710 is an enterprise-class server that balances power, flexibility, and efficient management features. With its dual-processor capability, extensive memory options, robust storage configurations, and advanced management tools, it remains a solid choice for organizations looking to streamline their IT operations and enhance performance.
