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 made available free of charge to the storage research and development communities in both academia and industry.
Begin downloading trace data files. Links to the specific trace types can always be found on the left.
May 22, 2013: Scheduled Instability: The IOTTA Trace Repository will be unstable from 5 PM PDT on May 22, 2013, to 5 PM PDT on May 24, 2013. During this time, we will be upgrading the system to a new release of the OS. There will be at least one reboot during this period, and the site may be unreliable in other ways. If you experience problems, please try again later.
May 20, 2013: The IOTTA server will be rebooted on Tuesday May 21, 2013, between 1 and 3 PM PDT. This reboot is necessary as part of a system upgrade.
May 03, 2013: On Wednesday May 8th, between 2pm and 5pm PDT, the server will be down for maintenance. During that time, the IOTTA website will not be available. We are sorry for the inconvenience.
January 27, 2013: Several "SNIA SSSI WIOCP metrics" packages are now available for download from the IOTTA Repository. These summary I/O operation performance metrics were collected by participants in the SNIA Solid State Storage Initiative (SSSI) Workload I/O Capture Program (WIOCP). The WIOCP is a project undertaken by the SNIA SSSI to collect contemporary I/O operation performance metrics that reflect the actual I/O operation activity performed during normal application/workload usage. These empirical metrics are collected separately for both monitored devices and processes/applications. Please also consider becoming a SSSI WIOCP participant - the metrics that you collect will be a valuable addition to the IOTTA Repository and a valued benefit to the storage community at large!
