High-level procedures to set this up are described here: http://csl.cse.psu.edu/?q=node/322 This will provide me with an environment to simulate DFTL, Page Mapping FTL, and FAST. The first step is to get DiskSim3.0 installed and working. I was able to get DiskSim3.0 installed, configured, and compiled successfully using the procedures that are posted here: http://www.pdl.cmu.edu/DiskSim/Compiling_DiskSim3.0_v1.0.pdf However, I was not sure how to complete the remaining steps on http://csl.cse.psu.edu/?q=node/322 to get FlashSim working correctly. The instructions say to extract src.release.tar.gz which I did. But am I supposed to get rid of my existing (and correctly functioning) ~/disksim-3.0/src directory and replace it with the src.release directory? I wasn't sure if I should get rid of it or copy over it with the new src.release contents. Also, after that is resolved, what is the proper command I should use to correctly "make" the files? Any help is greatly appreciated. Thanks. Jonathan -------------- next part -------------- An HTML attachment was scrubbed...

So after I have DiskSim 3.0 working, I backed up the DiskSim src directory: cd ~/disksim/disksim-3.0 mv src src_orig I then put src.release (from FlashSim) to src (in DiskSim directory): cp -pR /tmp/src.release ~/disksim/disksim-3.0/src I updated my .paths and .paths.in accordingly inside ~/disksim/disksim-3.0/src: #update the LIBPARAM_PREFIX and LIBDDBG_PREFIX in the .paths.in file to have path of disksim directory export LIBPARAM_PREFIX=/home/jontjioe/disksim/disksim-3.0/libparam export LIBDDBG_PREFIX=/home/jontjioe/disksim/disksim-3.0/libddbg export DISKMODEL_PREFIX=/home/jontjioe/disksim/disksim-3.0/diskmodel cp .paths.in .paths And then, I run the patch which updates dftl.c, disksim_logorg.c, fast.c, flash.c, pagemap.c, and syssim_driver.c: cd ~/disksim/disksim-3.0/src patch -p1 -i flashsim-20100324.patch I then attempted to compile the src directory: cd ~/disksim/disksim-3.0/src make This is the error I get: << jontjioe at

Due to a bug in the disksim code, getssd will use the current disk index as an index into the table of ssd disks. So if there are three magnetic disks, and one SSD, when trying to access disk 3 (the SSD), it will try to getssd(3). But since the count of SSDs is only 1, it will fall off the table. To avoid this, keep your system purely SSD apply the second patch to your config. 2) Once this is bypassed, the code will fail on an assertion that your page size does not match the aligned count as returned by ssd_choose_aligned_count. The value that function returns is MIN(count, block number % page size). If count is 4 and page size is 8, you will have problems. I don't know what that means for your experiments, but you can either change page size to 4 or apply the first patch. The patch will ignore the difference.

I am not sure if it is the correct way I compression, However you can compress each address that exceed the total block address limit in your SSD. 2. You mean that ASU field represent the disk number for each request ? If you mean this, I think It is better to filter request from one disk and feed them in new trace file to disksim.

Basically I look for a way to use DiskSim to simulate several disks spread over the LAN network. I had a look at "disksim_interface.c" and found that disksim is a global variable, so it is probably impossible to instantiate several disksim instances in the same processe. Another (unpleasant) option may be to create several processes - where each process is dedicated to instantiating one disksim instance. This option is complex to manage. Here is my question: is there a simpler way to simulate several disks? Thanks in advance, Roman -------------- next part -------------- An HTML attachment was scrubbed...
