Abstract

Systems and methods are provided for throughput optimization of a hard disk drive (HDD) using position error signaling (PES) that includes determining a PES for a HDD mounted in a chassis based on a dynamic disturbance. The method also includes calculating a critical parameter of the PES. The method further includes indicating a mechanical design modification of the HDD or the chassis if the critical parameter of the PES exceeds a pre-defined threshold.

Claims (51)

1. A method for throughput optimization of a hard disk drive (HDD) using position error signaling (PES) comprising:

for each of a plurality of HDDs in an array mounted in a chassis:

determining a PES based on a dynamic disturbance;

calculating a critical parameter of the PES; and

determining a performance parameter;

generating a performance map of the array; and

indicating a mechanical design modification of a particular HDD in the array or the chassis if the critical parameter of the PES for the particular HDD exceeds a pre-defined threshold or the performance parameter for the particular HDD fails to meet a pre-defined tolerance.

2. The method of claim 1 , wherein the critical parameter is a mean.

3. The method of claim 1 , wherein the dynamic disturbance is from a fan associated with the chassis.

4. The method of claim 1 , further comprising:

correlating the PES for the particular HDD to throughput of the particular HDD;

indicating a mechanical design modification of the particular HDD or the chassis based on the correlation between the PES for the particular HDD and the throughput of the particular HDD.

5. The method of claim 1 , further comprising:

correlating the PES for the particular HDD to dynamics of a fan associated with the chassis;

indicating a mechanical design modification of the particular HDD, the fan, or the chassis based on the correlation between the PES for the particular HDD and the fan dynamics.

6. The method of claim 1 , wherein the performance map comprises a location in the chassis of each of the plurality of HDDs.

7. The method of claim 1 , wherein the performance map comprises a performance ranking of each of the plurality of HDDs.

8. The method of claim 1 , further comprising:

determining acceleration data for each of the plurality of HDDs based on an on-board acceleration sensor; and

correlating the PES to the acceleration data for each of the plurality of HDDs.

9. A hard disk drive (HDD) comprising:

a processor configured to:

for each of a plurality of HDDs in an array mounted in a chassis:

determine a PES for based on a dynamic disturbance;

calculate a critical parameter of the PES; and

determine a performance parameter;

generate a performance map of the array; and

indicate a mechanical design modification of a particular HDD in the array or the chassis if the critical parameter of the PES for the particular HDD exceeds a pre-defined threshold or the performance parameter for the particular HDD fails to meet a pre-defined tolerance.

10. The HDD of claim 9 , wherein the critical parameter is a mean.

11. The HDD of claim 9 , wherein the dynamic disturbance is from a fan associated with the chassis.

12. The HDD of claim 9 , wherein the processor is further configured to:

correlate the PES for the particular HDD to throughput of the particular HDD;

indicate a mechanical design modification of the particular HDD or the chassis based on the correlation between the PES for the particular HDD and the throughput of the particular HDD.

13. An information handling system comprising:

a processor;

a hard disk drive (HDD) communicatively coupled to the processor; and

a computer-readable medium communicatively coupled to the processor and having stored thereon instructions configured to, when executed by the processor:

for each of a plurality of HDDs in an array mounted in a chassis:

determine a PES based on a dynamic disturbance;

calculate a critical parameter of the PES; and

determine a performance parameter;

generate a performance map of the array; and

indicate a mechanical design modification of a particular HDD in the array or the chassis if the critical parameter of the PES for the particular HDD exceeds a pre-defined threshold or the performance parameter for the particular HDD fails to meet a pre-defined tolerance.

14. The system of claim 13 , wherein the critical parameter is a mean.

15. The system of claim 13 , wherein the dynamic disturbance is from a fan associated with the chassis.

16. The system of claim 13 , wherein the instructions are further configured to:

correlate the PES for the particular HDD to throughput of the particular HDD;

indicate a mechanical design modification of the particular HDD or the chassis based on the correlation between the PES for the particular HDD and the throughput of the particular HDD.

17. The system of claim 15 , wherein the instructions are further configured to:

correlate the PES for the particular HDD to dynamics of a fan associated with the chassis;

indicate a mechanical design modification of the particular HDD, the fan, or the chassis based on the correlation between the PES for the particular HDD and the fan dynamics.
