CH242 CPUs

2

The CH242 supports one, two, or four Intel? Xeon? E7-4800 (Westmere) CPUs with six, eight, or ten cores at 95 W, 105 W, or 130 W, or Intel? Xeon? E7-8800 (Westmere) CPUs with eight or ten cores at105 W or 130 W.

? Each CPU is integrated with two memory controllers:
? Each memory controller supports two Intel? Serial Management Interfaces (SMIs). Each SMI supports one MillBrook.
? Each MillBrook supports two DDR3 memory channels. Each DDR3 channel supports one DIMM at the DDR3 1333 or 1600 MHz frequency.
Maximum clock frequency: 2.66 GHz

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.
