RUNTIME DYNAMIC PERFORMANCE SKEW ELIMINATION

摘要

Exemplary method, system, and computer program product embodiments for runtime dynamic performance skew elimination in a computer environment are provided. In one embodiment, the computer environment is configured for calculating a rank heats by utilizing a plurality of fine-grained statistics collected at an extent granularity, including considering bandwidth (BW) and input/outputs per second (IOPS) metrics. An adaptive data placement plan is generated to relocate the data. The data is placed among data storage ranks. The data storage ranks are balanced according to the adaptive data placement plan.
