ESXi hardware monitoring

Hello,

I have a question related to how ESXi checks hardware health status. For example, I have a Synergy 660 Gen10 and Huawei E9000 CH121 V3, for Gen10 I see the following:

wbem and sfcbd is disabled but there is information about sensors for this ESXi host.

For CH121 V3:

For CH121 V3 wbem and sfcbd is enable and there is also information about sensors.Can someone explain to me what is the difference between CH121 V3 and Gen10? Does Gen10 use iLO and ipmi for hardware monitoring?
