blkreplay-examples

Description

blkreplay is a utility driving the block layer of the operating system while measuring latency and throughput of I/O operations for later visualisation.

blkreplay can create artificial loads (random read-write sweeps, various kinds of overload tests) or replay natural loads which have been recorded by blktrace or a similar utility run at production servers.

blkreplay can be used to test physical hardware, to compare different brands of hard disks or RAID controllers, to evaluate the effect of SSD caching, to compare different block level transports like iSCSI vs Fibrechannel and so on.

This package contains example configuration files and example loads, artifician and natural.
