What is a function of the 3D Sea of Sensors on ProLiant Gen8 servers?
A.
They maintain a copy of the host server Integrated Management Log (IML).
B.
They record user actions such as powering the server on and off and making user configuration
changes, and generate an audit log
C.
They power on fans and make other adjustments to reduce energy usage when temperatures
get too high
D.
They reduce the number of fans required by 50% compared to previous ProLiant server models
Explanation:
HP Sea of Sensors 3D
Introduced with ProLiant G6 servers, HP Sea of Sensors provides the data to precisely control the server fans and directly cool specific components, while not overcooling other components. This can reduce fan power consumption up to dozens of watts per server.
HP Sea of Sensors 3D in ProLiant Gen8 servers extends the use of sensors to select PCI Express option cards, FlexibleNetwork Adapters, and FlexFabric Adapters to get a three-dimensional temperature profile in the server. This additional data enables more precise and efficient cooling of ProLiant Gen8 servers. The data is included in the always-on diagnostic information of the HP Active Health System.
