Abstract
By supplying auxiliary power to a blade's optional components, instead of polling the blade for the power requirements of a fully configured module, each installed component can be individually polled and the values summed to produce a more accurate value representing the actual power needs of a blade system prior to booting.
Claims7
A server-based computing system comprising:
- a plurality of servers each having at least one processor operable to process data,
- a plurality of onboard components including at least one NVRAM,
- optional modules having FRU EEPROMs,
- each component and module operable to respond to requests from the at least one processor;
- and
- a plurality of power supplies, the power supplies operable to:
- supply power to the servers;
- and
- provide auxiliary power to the NVRAMs and the FRU EEPROMs.
6 more elements
A method of determining blade computing module's power requirements in a blade server system comprising:
- powering the blade's onboard NVRAM from auxiliary power;
- powering each of a plurality of optional module's FRU EEPROMs from auxiliary power;
- requesting base configuration power requirements from the blade's onboard NVRAM;
- requesting power requirements of each one of the plurality of optional modules;
- and
- aggregating the requested power requirements to determine the actual power requirements for the blade as configured.
3 more elements
A computer software program stored on a computer-readable medium comprising code that causes the following in a blade server system:
- power a blade's onboard NVRAM from auxiliary power;
- power each of a plurality of optional module's FRU EEPROMs from auxiliary power;
- request base configuration power requirements from the blade's onboard NVRAM;
- request power requirements of each one of the plurality of optional modules;
- and
- aggregate the requested power requirements to determine the actual power requirements for the blade as configured.
