We are planning to compare operation of the hard drive according to the following scenarios:įor the workload we are going to use Iometer, which is an I/O subsystem measurement and characterization tool: We’ll use Diskspd test later, as well ( ).Īlso, the workload will include 4 workers, 16 outstanding IOs, and 4K random write.
To study ReFS performance with FileIntegrity off/on we need to run series of experiments. It is the second part of ReFS performance testing. This paper tells about the second part of the testing, which is intended to explore Resilient File System (ReFS) performance with FileIntegrity option off and on.

The full description of the test can be found here: What has been observed with it is that with FileIntegrity option on or off, ReFS behaves differently: either as a conventional or log-structured file system.
The first one was intended to study I/O behavior in ReFS with FileIntegrity option off and on. So, if FileIntegrity option is off, the system won’t “know” about the data corruption (if any), and if it’s on, then the system will be aware.Ī testing has been run to see how ReFS performs under typical virtualization workload. Its predecessors, in contrast, required administrators to manually run CHKDSK or similar utilities for this purpose. With FileIntegrity on, ReFS automatically checks data integrity by examining this checksum data. Also, the file system can have its own checksum in a separate integrity stream. Its data protection feature is represented by the FileIntegrity option, which is responsible for file scanning and repair processes.Īll ReFS metadata has a 64-bit checksum, which is stored independently of file data.

ReFS (Resilient File System – ) is a Microsoft file system, which ensures data integrity by means of resiliency to corruption (irrespective of software or hardware failures), increases data availability and scales to large data sets across various workloads.
