Section 4. Power, Thermal, Acoustic

A. Power Efficiencies

One of the main features of the 11th generation of PowerEdge servers is enhanced power efficiency. The

R610 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

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

•Increased rear venting / 3D venting

•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-swap 502W Energy Smart power supplies in a 1+1 configuration. A 717W 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. The R610 power supplies do not have embedded cooling fans; the PSUs are cooled only by the system cooling fans. The three status LEDs on the PSU have been replaced with a single bi-color LED starting with the PT build.

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).

If using only one power supply, the single PSU should be installed in the PS1 bay and a PSU Close Out (metal cover) will be installed in the PS2 bay. The use of the PS1 bay for the single PSU configuration is done for consistency only – there is nothing that prevents the use of the PS2 bay in a single PSU configuration.

R610 specifications

The Dell PowerEdge R610 is a 1U rack server that combines outstanding performance with advanced management features, making it ideal for enterprises and small to medium-sized businesses. Introduced as part of Dell’s 11th generation of servers, the R610 is designed to meet demanding workloads while optimizing energy consumption.

One of the main features of the R610 is its dual-socket capability, supporting up to two Intel Xeon 5500 or 5600 series processors. This allows significant scaling of compute power, enabling users to run multiple applications concurrently without a hitch. The server supports up to 192 GB of DDR3 memory with 18 DIMM slots, providing ample bandwidth for memory-intensive workloads.

Storage flexibility is another hallmark of the R610. It offers a choice of up to six 2.5-inch SAS, SATA, or solid-state drives, which allows for impressive storage capacities and the option for RAID configurations. This ensures data integrity and high availability, catering to the needs of various applications from databases to virtual environments.

The Dell R610 introduces advanced virtualization technologies, with support for VMware and Microsoft Hyper-V, making it an excellent choice for virtualized environments. With the option to deploy multiple virtual machines on a single physical server, organizations can maximize resource allocation and reduce costs.

In terms of management, the R610 is equipped with the Integrated Dell Remote Access Controller (iDRAC) which provides out-of-band management capabilities. This feature allows administrators to monitor system health, perform firmware updates, and manage hardware without the need for physical access to the server.

Energy efficiency is a notable characteristic of the R610, complying with Energy Star requirements. It utilizes lower power consumption components and features such as dynamic power management, which adjusts the power usage based on real-time workload demand. This characteristic contributes to lower operational costs and a reduced environmental footprint.

The Dell PowerEdge R610 excels in providing an optimal balance of performance, manageability, and energy efficiency, making it a powerful tool for IT environments that demand reliability and scalability. Its robust feature set and support for virtualization technologies position it as a favorable choice for businesses looking to enhance their IT infrastructure efficiently.
