Abstract

A system with a local data collector that collects power management data for a subsystem. The local data collector can determine whether a first formatting associated with a first channel between the local data collector and a system power management data collector is equivalent to a second formatting associated with a second channel between the local data collector and the system power management data collector, and in response to a determination that the first formatting and second formatting are not equivalent format the power management data according to the first formatting; store the power management data formatted according to the first formatting in a first location in a memory; format the power management data according to the second formatting; and store the power management data formatted according to the second formatting in a second location the memory.

First claim

What is claimed is:

1. A method comprising:
collecting, by a local data collector, power management data for a memory subsystem in a computer system comprising a system power management data collector, wherein the memory subsystem comprises:
a sensor configured to generate the power management data; and
the local data collector, wherein the local data collector comprises a computer processor:

determining, by the local data collector, whether a first formatting associated with a first channel between the local data collector and the system power management data collector is equivalent to a second formatting associated with a second channel between the local data collector and the system power management data collector;
in response to determining, by the local data collector, that the first formatting and second formatting are not equivalent:
formatting, by the local data collector, the power management data according to the first formatting;
storing, by the local data collector, the power management data formatted according to the first formatting in a first location in a memory of the memory subsystem;
formatting, by the local data collector, the power management data according to the second formatting; and
storing, by the local data collector, the power management data formatted according to the second formatting in a second location in the memory.

2. The method of claim 1 further comprising:
marking the first memory location as updated; and
marking the second memory location as updated.

3. The method of claim 1 further comprising:
in response to determining, by the local data collector, that the first formatting and second formatting are equivalent:
formatting the power management data according to the first formatting; and
storing the power management data formatted according to the first formatting in a third location in the memory.

4. The method of claim 3 further comprising marking the third memory location as updated.

5. The method of claim 1 , wherein collecting the power management data comprises:
collecting thermal data from thermal sensors that sense temperature throughout the memory subsystem; and
collecting performance data about the memory subsystem.

6. An apparatus comprising:
a memory comprising:
a sensor that generates power management data for the memory; and
a local data collector configured to:
collect the power management data;
determine whether a first formatting associated with a first channel between the local data collector and a system power management data collector is equivalent to a second formatting associated with a second channel between the local data collector and the system power management data collector; and
in response to a determination that the first formatting and second formatting are not equivalent, the local data collector is configured to:
format the power management data according to the first formatting;
store the power management data formatted according to the first formatting in a first location in the memory;
format the power management data according to the second formatting; and
store the power management data formatted according to the second formatting in a second location in the memory.

7. The apparatus of claim 6 , wherein the local data collector is further configured to:
mark the first location in the memory, as updated; and
mark the second location in the memory, as updated.

8. The apparatus of claim 6 , wherein the local data collector is further configured to:
in response to a determination that the first formatting and second formatting are equivalent:
format the power management data according to the first formatting; and
store the power management data formatted according to the first formatting in a third location in the memory.

9. The apparatus of claim 8 wherein the local data collector is further configured to mark the third location of the memory as updated.

10. The apparatus of claim 6 , wherein the local data collector is further configured to:
collect thermal data from thermal sensors that sense temperature throughout the memory; and
collect performance data about the memory.

11. A computer program product for scalable data collection, the computer program product comprising:
a computer readable storage medium having computer usable program code embodied therewith, the computer usable program code configured to:
collect, by a local data collector, power management data for a memory subsystem, wherein the memory subsystem comprises:
a sensor that generates power management data for the memory subsystem; and
the local data collector;

determine, by the local data collector, whether a first formatting associated with a first channel between the local data collector and a system power management data collector is equivalent to a second formatting associated with a second channel between the local data collector and the system power management data collector;
in response to a determination that the first formatting and second formatting are not equivalent:
format, by the local data collector, the power management data according to the first formatting;
store, by the local data collector, the power management data formatted according to the first formatting in a first location in the memory;
format, by the local data collector, the power management data according to the second formatting; and
store, by the local data collector, the power management data formatted according to the second formatting in a second location the memory.

12. The computer program product of claim 11 , the computer program code further configured to:
mark the first location in the memory, as updated; and
mark the second location in the memory, as updated.

13. The computer program product of claim 11 , the computer program code further configured to:
in response to a determination that the first formatting and second formatting are equivalent:
format the power management data according to the first formatting; and
store the power management data formatted according to the first formatting in a third location in the memory.

14. The computer program product of claim 13 , the computer program code further configured to mark the third location in the memory, as updated.

15. The computer program product of claim 11 , wherein:
the sensor comprises one or more thermal sensors that sense temperature throughout the memory subsystem; and
the computer program code is further configured to:
collect thermal data from the thermal sensors; and
collect performance data about the memory subsystem.
