CH140 CPUs

1

Each child compute node of the CH140 supports one or two Intel? Xeon E5-2600 or E5-2600 v2 (Sandy Bridge-EP or Ivy Bridge-EP) 4-core, 6-core, 8-core, 10-core, or 12-core CPUs of 70 W, 80 W, 95 W, 115 W, or 130 W.
Each CPU integrates memory controllers and supports four DDR3 memory channels. Each channel supports one DDR3 DIMM of 1333, 1600, and 1866 MHz.
Each CPU integrates a PCIe controller for supporting PCIe 3.0 and providing 8 lanes.
The two CPUs are interconnected through two QuickPath buses at 8.0 GT/s.
Maximum clock frequency: 3.5 GHz

For Huawei server CPU specifications, enter a product model + CPU; for example, RH2288 V3 CPU.

CPU overclocking
CPU overclocking allows the CPU to run at higher clock rates than the nominal rate. This will affect the server stability. Huawei servers do not support the setting of CPU overclocking. However, the BIOS setup interface provides the Turbo mode for CPUs. You can enable the Turbo mode (auto, intelligent speed adjustment) to speed up the CPU. For details, search for the keyword "Turbo mode" in http://support.huawei.com/ehedex/hdx.do?docid=DOC1000010818&lang=en&idPath=7919749|9856522|21782478|21782482|9768163&clientWidth=1520&browseTime=1494381933313.

CPU models requirements
A server must use the same model of CPUs. Otherwise, the server cannot run normally.

How to configure the CPU Usage Alarm Threshold?
Using the set cpu-usage threshold command, you can set the CPU usage alarm threshold and CPU usage alarm recovery threshold. Using the undo set cpu-usage threshold command, you can restores the default CPU usage alarm threshold and CPU usage alarm recovery threshold. By default, the CPU usage alarm threshold is 80% and the CPU usage alarm recovery threshold is 75%. ?When the CPU usage alarm threshold is lower than 60%, the default CPU usage alarm recovery threshold is 1% lower than the CPU usage alarm threshold. ?When the CPU usage alarm threshold is higher than or equal to 60%, the default CPU usage alarm recovery threshold is 5% lower than the CPU usage alarm threshold.
