I know that many would be interested in this, and some may not have
seen it.

Hello -

You all have at one time or another requested access to the source code for the DiskSim extension that we described in our USENIX ¡¯08 paper ¡°Design Tradeoffs for SSD Performance¡±.

This extension is now available under a limited non-commercial (click-through) license from the MSR download site:

http://research.microsoft.com/research/downloads/default.aspx

This download takes the form of a new ¡°ssdmodel¡± source subdirectory for the DiskSim source tree, along with a patch file that should modify the existing DiskSim source files to insert hooks for the new code.  A top-level directory is also created for a VisualStudio build of DiskSim if you want it, but the patched environment should compile under Linux and CygWin as well.  We haven¡¯t tested it for Macs.

We assume that you are starting with the DiskSim 4.0 release of mid-June (6/23/2008).  We have only tested the main release, not the one with DIXTrac.

Remember that this code simulates an idealized SSD (e.g., one that doesn¡¯t exist in practice) that is parameterized solely by the performance of NAND flash parts.  We have been unsuccessful so far in guessing the algorithms used in commercial SSDs well enough to validate our simulation.

This code has so far not been tested outside of our lab, so there may be bugs ¡¦ especially in the installation steps.  We seek your help in finding such bugs before making a wider announcement (e.g. on the DiskSim distribution list).

Please let us know how you fare.

Best regards,

Ted Wobber and Vijayan Prabhakaran
