IOTTA Repository Home

The SNIA IOTTA Repository is a collaborative effort sponsored by the Storage Networking Industry Association's Input/Output Traces, Tools, and Analysis Technical Work Group (IOTTA TWG). The primary goal of this collaboration is to create a worldwide repository for storage-related I/O trace files, associated tools, and other related information, all of which are made available free of charge to the storage research and development communities in both academia and industry.

November 15, 2018: Trouble Downloading? Try clearing your cookies, or downloading a new copy of the shell script. We have observed some downloading problems that seem to be related to recent upgrades; clearing cookies might help. If not, please use the "Contact Us" button to ask for assistance.

November 11, 2018: Ongoing maintenance: We are performing maintenance on the IOTTA site throughout the month of November. To the extent possible, we will keep a mirror up during the process so that there will be no interruption in service. However, it is possible that if you have are using a shell or BAT script to download traces, you will be unable to contact the mirror listed in the script. If that happens, you should be able to resolve the problem by downloading a new copy of the script. If you have other difficulties, please do not hesitate to contact us.

There may also be brief periods when the entire site is down; we will try to keep those times as short as possible.

We apologize for any inconvenience.

July 18, 2018: New Traces: We have posted some new traces, including MobiGen, Docker Registry, FSL-Dedup, PFS-SysCall, and an ASCII version of the CMU DFS Traces.
