Self-detecting storage bottleneck while handling sequential I/O operations
First Claim
Patent Images
1. A method for self-detecting storage bottleneck by a processor device in a computing environment, the method comprising:
- injecting delay commands into sequential input/output (I/O) requests and measuring effects of the injected delay commands for determining whether a storage system handling the sequential input/output (IO) requests is causing a bottleneck; and
delaying a processing of the sequential I/O requests for a time period when injecting a delay command.

Abstract
Delay commands are injected into sequential input/output (I/O) requests and the effects of the injected delay commands are measured for determining whether a storage system handling the sequential input/output (IO) requests is causing a bottleneck, while the processing of sequential I/O requests is delayed for a time period when injecting the delay command.
