Understanding I/O Patterns at the Block Level with ioprof

Jeff Layton

Over at Admin HPC, Intel’s Jeff Layton writes that understanding how data makes its way from the application to storage devices is key to understanding how I/O works and that monitoring the lowest level of the I/O stack, the block driver, is a crucial part of this overall understanding of I/O patterns.
