DISKSPD is a storage load generator / performance test tool from the Microsoft Windows, Windows Server and Cloud Server Infrastructure Engineering teams. Please see the included documentation (docx and pdf formats).
In addition DISKSPD itself, this repo hosts measurement frameworks which use DISKSPD. The initial example is the VM Fleet being used for Windows Server 2016 Hyper-Converged Storage Spaces Direct work. Look for these under the Frameworks directory.
DISKSPD 2.0.16b 2/22/2016
- -ag is now default (round robin group-aware affinity)
- new -ag# for group-aware thread->core affinity assignment
- -Sr : remote cache mode
- -Sh : equivalent to -h, all cache modes collapsed under -S
<ProcessorTopology>(under<System>) element in XML results shows Processor Group topology of the system the test executed on<RunTime>(under<System>) element shows run start time in GMT- -ft : specifies
FILE_ATTRIBUTE_TEMPORARY_FILEon open (note: work in progress, effect of this attribute is not fully lit up yet)
VM Fleet 0.4 4/14/2016
- bugfix: master.ps1 now takes connection credentials as parameters; this allows master to be edited on the fly, it is no longer templated
- credential templating moves to launch.ps1, which is now generated into the VMs
- pause handling now uses an epoch ask/response from the VMs
- check-pause uses the epoch to directly test whether a given VM has indeed acknowledged the current pause request, and is definitive with respect to all running VMs
- new automated sweep mechanic
Compilation is supported with Visual Studio and Visual Studio Express. Use the Visual Studio solution file inside the diskspd_vs directory.
