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.
