specifications.

5.2 Power Efficiency

One of the main features of blade servers is enhanced power efficiency. The Dell™ PowerEdge™
M610x achieves higher power efficiency by implementing the following features:
•
User-configurable power options through the M1000e Chassis Management Controller (CMC)
(see the M1000e documentation online at
•
Improved power budgeting
•
Voltage Regulator (VR) efficiency improvements
•
CPU VR dynamic phase shedding
•
Switching regulators instead of linear regulators
•
Closed loop thermal throttling
•
Use of DDR3 memory (lower voltage compared to DDR2)
•
Memory VR static phase shedding
•
BIOS Power/Performance options page
•
Active Power Controller (BIOS-based CPU P-state manager)
•
Ability to throttle memory
•
Ability to disable a CPU core
•
Ability to turn off embedded NICs or PCIe lanes when not being used
•
Energy Smart components at the M1000e chassis level to selectively enable more computing
performance with less power consumption.

5.3 Thermal Operating and Storage Specifications

The M610x thermal solution includes:

Optimized airflow impedance for individual blade and chassis level airflow balancing

Custom air baffling directs airflow through the components to maintain proper cooling

Custom designed heat sinks maintain CPU, DIMM, and board-level chip temperatures within
thermal design targets

Separate airflow cooling path for the two full-length x16 PCIe Gen2 slots.

Support for dual slot NVIDIA

Highly Optimized Fan Control Algorithm
o Base fan speeds are a function of hardware configuration and ambient temperature to
minimize airflow for a given environment.
o Component algorithms: CPU PID, DIMMs, HW Configuration, IOH, GPU, and External
Ambient.
o The highest fan speed request from the above algorithms is used to set the
appropriate fan speed for the blade.
o Ambient and HW Configuration sets the minimum; other algorithms increase fan speed
to maintain proper cooling.
