Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 11/36

US Classification:

717126, 717124

Abstract:

A method, system, and computer program product for facilitating deduplication product testing in a computing environment is provided. At least one deduplication test file is generated. The at least one deduplication test file is adapted for, when processed through the deduplication product testing, exhibiting a predefined deduplication factor. A definition file is initialized. The definition file defines at least one file characteristic addressed during the generating the at least one deduplication test file to obtain the predefined deduplication factor. The file characteristic may include a file pattern, a file/pattern ratio, and a pattern across multiple files.

Abstract:

An apparatus, system, and method of simulating communications between a plurality of devices are provided. A series of commands and data block sizes are recorded as trace data by a recording device and stored in a library of trace data. The system functionally includes a first device and a second device, the second device being the device under test. The first device can be replaced by an apparatus that simulates the communications of the first device with the second device. The simulator recreates the commands of the first device by accessing the prerecorded trace data. An apparatus, system and method for measuring and analyzing the performance of modifications made to the trace data are also provided.
