Facilitating outlier object detection in tiered storage systems

A system, comprising:

• a processor;
• and
• a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
• determining respective parameters associated with objects of a group of objects of a tiered storage system, wherein the respective parameters comprise a size, an access percentage, and a cost;
• using the respective parameters associated with the objects of the group of objects as inputs, performing data cluster analysis on the group of objects, resulting in at least one data cluster;
• and
• selecting at least one object from the group of objects as at least one outlier object within the tiered storage system based on the at least one data cluster, wherein the at least one outlier object is selected to reduce a performance capability of the tiered storage system as compared to the objects of the group of objects other than the at least one object, wherein the selecting comprises determining that the at least one object is different from other objects of the tiered storage system based on a result of the data cluster analysis, and wherein the at least one outlier object has a size, an access percentage, and a value that are different than respective sizes, respective access percentages, and respective values of the other objects of the tiered storage system.

A system, comprising:

• a processor;
• and
• a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
• determining first parameters associated with a file in a tiered storage system, wherein the first parameters comprise first information indicative of an access time associated with the file and second information indicative of a modification time associated with the file;
• comparing the first parameters with other parameters associated with other files in the tiered storage system, wherein the parameter and the other parameters are similar parameters;
• and
• determining that the file is an outlier based on the comparing indicating the file is different from the other files in the tiered storage system, wherein the determining that the file is the outlier comprises determining that the file is different from the other files of the tiered storage system based on a result of a data cluster analysis, and wherein the outlier is identified as being in an improper tier of the tiered storage system based on the outlier having a level of performance determined to be a lower level of performance as compared to respective levels of performance of the other files in the tiered storage system, and wherein the file that is the outlier comprises a size, an access percentage, and an associated value that are different than respective sizes, respective access percentages, and respective associated values of the other files of the tiered storage system.
