2. A data center management unit according to claim 1 ,

wherein said data center management unit comprises a mechanism configured for detecting micro-interruptions in power, measuring durations of said micro-interruptions, and measuring phase shifts in relation to such micro-interruptions.

3. A data center management unit according to claim 1 ,

wherein said data center management unit further comprises:

power metering circuitry for measuring overall power consumption at said power inlet; and wherein

said processor is adapted to apply a first priority scheme for de-activating power outlets of said plurality of power outlets in a first priority order whenever said overall power consumption exceeds an overall threshold.

4. A data center management unit according to claim 3 ,

wherein said first priority scheme is based on comparison of long term values, logged for a long term being 1 day or more, and short term values, logged for a short term between zero and fifteen minutes, of said logged parameter values or events; and

wherein in case of equal priority based on said comparison a power outlet which is more recently activated is prioritized for de-activation.

5. A data center management unit according to claim 1 ,

wherein said processor is adapted to apply a second priority scheme for re-activating power outlets out of said plurality of power outlets in a second priority order after a power outage.

6. A data center management unit according to claim 5 ,

wherein said second priority scheme is based on comparison of long term values, logged for a long term being 1 day or more, and short term values, logged for a short term between zero and fifteen minutes, of said logged parameters or events.

7. A data center management unit according to claim 1 ,

wherein said processor is adapted to de-activate a power outlet of said plurality of power outlets whenever a power measurement for said power outlet exceeds a predetermined per-outlet threshold.

8. A data center management unit according to claim 1 ,

said data center management unit further comprising memory for storing one or more parameter values during start-up of a computer out of said computers.

9. A data center management unit according to claim 8 ,

wherein said processor is adapted to determine sequence and timing of re-starting said computers after a power disaster based on said parameter values stored during start-up of said computer.

10. A data center management unit according to claim 8 ,

wherein said processor is adapted to instruct deactivation of a computer or alerting when parameter values measured during operation of said computer approach said parameter values stored during start-up of said computer within predetermined limits.

11. A data center management unit according to claim 1 ,

said data center management unit further comprising memory for storing the frequency spectrum of current and voltage measured at a power outlet of said plurality of power outlets.

12. A data center management unit according to claim 11 ,

wherein said processor is adapted to analyse harmonics in said frequency spectrum for threat and failure prediction.

13. A data center management unit according to claim 1 ,

wherein said logged parameters or events comprise one or more of the following:

temperature in said data center;

humidity in said data center;

airflow in said data center;

current measured at a power outlet of said plurality of power outlets;

total harmonic distortion or THD;

power factor of a plurality of said power outlets;

voltage measured at said power inlet;

energy consumed by a power outlet of said plurality of power outlets;

power consumed by a power outlet of said plurality of power outlets;

leakage current at a power outlet of said plurality of power outlets;

short circuit events.

14. A method for managing and controlling power distribution towards computers in a data center via a data center management unit comprising a power inlet, a plurality of power outlets and a processor,

wherein said method comprises:

storing one or more logged parameters or events; and

taking measures for disaster prevention to avoid power outages of computers or racks of computers in said data center and/or measures for disaster recovery to reboot computers or racks of computers in said data center after a power outage, said measures for disaster prevention and/or disaster recovery including:

generating alert messages;

de-activating one or more power outlets of said plurality of power outlets;

activating one or more power outlets of said plurality of power outlets; and

re-activating a power outlet that has been de-activated earlier,

wherein said method comprises analysing changes in time of values of said logged parameters or events comprising a comparison of short term values, logged for a short term between zero and fifteen minutes, and long term values, logged for a long term being 1 day or more, of said logged parameters or events,

and wherein said method comprises taking one or more of said measures for disaster prevention and/or disaster recovery based on said comparison of short term values and long term values of said logged parameters or events.
