Abstract: Systems and techniques are described for analyzing input output I/O traces. One of the techniques includes receiving an I/O trace, the I/O trace identifying a temporal sequence of previously submitted I/O requests; partitioning the I/O trace into a plurality of partitions based on a load pattern of the I/O requests in the I/O trace and a data access pattern of the I/O requests in the I/O trace; and generating a signature for each partition, wherein the signature for each of the partitions identifies characteristics of the I/O requests in the partition, and wherein the characteristics of the I/O requests in the partition include the load pattern of the I/O requests in the partition and the data access pattern of the I/O requests in the partition.
