A method and system for visualizing sleep mode inner state processing are provided. In one embodiment, a method is provided that is performed in a computing device in communication with a storage system comprising a memory. The method comprises receiving information from the storage system concerning a number and duration of tasks performed by the storage system to exit a sleep mode; and displaying a visualization of the information. Other embodiments are provided.

A method and system for visualizing a correlation between host commands and storage system performance are provided. In one embodiment, a method comprises receiving information concerning host operations of a host performed over a time period; receiving information concerning storage system operations of a storage system performed over the time period; and simultaneously displaying both the host operations and the storage system operations over the time period. Other embodiments are possible, and each of the embodiments can be used alone or together in combination.

A method and system for write amplification analysis are provided. In one embodiment, a method is provided that is performed in a computing device. The method comprises determining an amount of data written from the computing device to a storage system over a time period, wherein the storage system comprises a memory; determining an amount of data written to the memory by the storage system over the time period; calculating a write amplification factor over the time period; and simultaneously displaying graphs of the amount of data written from the computing device over the time period, the amount of data written to the memory over the time period, and the write amplification factor over the time period. Other embodiments are possible, and each of the embodiments can be used alone or together in combination.

Method and system for write amplification analysis

A method and system for interactive aggregation and visualization of storage system operations are provided. In one embodiment, the method is performed by a server in communication with a client and comprises: receiving, from the client, data regarding storage system operations that were performed by a storage system over time, wherein each storage system operation is classified according to an operation type; receiving, from the client, a size of a graph to be displayed on the client's display device to visualize the storage device operations, wherein the size of the graph is defined by a number of tiles; for each tile, aggregating the storage system operations by operation type and identifying a dominant operation type; and sending, to the client, the identified dominant operation type for each tile. Other embodiments are provided.

Method and system for interactive aggregation and visualization of storage system operations

A method and storage device for assessing execution of trim commands are provided. In one embodiment, a trace of trim and write commands sent to a storage device are obtained. For each trim command in the trace, a subsequent write command to a same logical block address (LBA) as the trim command is identified, and an elapsed time between the trim and write commands is calculated. This information can be used to display a histogram and/or to optimize when the storage device executes trim commands and/or when the host device issues trim commands.
