Statement: SSDsim is a simulation tool of SSD’s internal hardware and software behavior. It provides specified SSD’s performance, endurance and energy consumption information based on a configurable parameter file and different workloads (trace file). SSDsim was created by Yang Hu in the end of 2009 and upgraded to version 2.0 after lots of modification and perfection. Its programming language is C and development environment is Microsoft Visual Studio 2008. With the help of Zhiming Zhu, Shuangwu Zhang, Chao Ren, Hao Luo, it is further developed into version 2.x. As the development team, we will continue adding new modules and functions to guarantee its persistent perfection. If you have any questions, suggestions or requirements about it, please feel free to email Yang Hu (yanghu@foxmail.com). We will adopt any reasonable requirements to make SSDsim better. Application steps: 1) Compile the code and generate an executablefile. A make clean B make all C, ./ssd 2) Run the executable file, input the name of trace file 3) Analyze the output file and statistic file for further experiments. Note: 1) Each request of the trace file possesses one line. A request should be ASCII and follow the format: request arriving time(int64), logical device number (int), logical sector number (int), request size (int), access operator (int, 1 for read, 0 for write). 2) The unit of the request arriving time is nanosecond and the unit of the request size is sector (512 Bytes). 3) No CRLF at the end of the last request line. 2011-12-03 # proj_4.csv read request average response time: 15833783343 write request average response time: 8921627996 read request average response time: 15725027419 write request average response time: 8904484477 read 108755924 0.006868599982965 write 17143519 0.001921568463478 #proj_0.csv read request average response time: 286477986761 write request average response time: 628389536649 read request average response time: 284309713962 write request average response time: 624740822304 read 2168272799 0.00762644641572 write 3648714345 0.005806453055309 #1720_flag.csv read request average response time: 1060618 write request average response time: 121404624 read request average response time: 1032437 write request average response time: 121340302 read: 28181 0.026570358036541 write: 0.000529815075248 #1815-lun1.csv read request average response time: 408626848 write request average response time: 372075158 read request average response time: 115555108 write request average response time: 151712481 read：293071740 0.717211170617942 write：220362677 0.592253130213009 #1719_flag.csv read request average response time: 1306901377 write request average response time: 2317744415 read request average response time: 229795953 write request average response time: 659140751 read: 1077105424 0.824167334242544 write: 1658603664 0.715611114524032 #1613-lun4.csv read request average response time: 58910971312 write request average response time: 67595758901 read request average response time: 18095022461 write request average response time: 25338743319 read: 40815948851 0.692841213478446 write: 42257015582 0.625143001114747 //prxy_0.csv 中间报错了，所以数据不准 read request average response time: 26003597440 write request average response time: 37593319210 read request average response time: 30931604416 write request average response time: 45630159207
