Software
RAID ReconSim is a DiskSim-based storage systems simulation tool that can be used to evaluate the performance impact of commonly-used RAID reconstruction algorithms including the Disk-Oriented Recovery(DOR) and Pipeline Recovery(PR) approaches. RAID ReconSim is trace-driven, and a few internal I/O events are introduced to control the RAID reconstruction process. In addition, RAID ReconSim can be used to measure the performance impact of other internal background tasks in RAID such as disk scrubbing and RAID resynchronization. RAID ReconSim is the basis of our SPA project. I plan to release it soon after the source code is cleaned up.
Vacuum is an inline deduplication-based virtual block device driver. Vacuum is implemented under the open-sourced Linux SCST framework(Generic SCSI Target Subsystem for Linux), so that it can be easily deployed in local or remoted machines for data deduplication through the standard SCSI conncections. Currently, Vacuum uses a fixed 4KB chunking, SHA1-160bit fingperinting scheme, three-layered index organization, two-tiered address mapping and multi-threaded I/O model. Vacuum is the basis of our CASE project, and preliminary results show the performance potential and stability of its implementation. I plan to release it soon after the source code is cleaned up.
DiskSim-4.0-with-power-support is a tool to evaluate the power consumption of storage systems based on Dempsey. I re-implemented the power evaluation functionality in DiskSim 4.0 and enabled it to support power evaluations of multi-disk storage systems, which is the basis of our RoLo project. You can download DiskSim-4.0-with-power-support here. If you are using it in your research project, please cite our paper:

HiFiRe is a new flexible strategy-based block-level I/O trace replayer, which is used to replace our first-generation block-level trace replayer tool -- RAIDmeter. You can download HiFiRe here. If you are using it in your research project, please cite our paper:
"Lei Xu, Hong Jiang, and Lei Tian. Hifire: A High Fidelity Trace Replayer for Large-Scale Storage Systems. Work-In-Progress Report and Poster Session in the 8th USENIX Conference on File and Storage Technologies(FAST'10), San Jose, CA, February, 2010."
SSDsim is an event-driven, modularly structured, and multi-tiered flash memory SSD simulator, which is capable of simulating most SSD hardware platforms, mainstream FTL schemes, allocation schemes, buffer management algorithms, and request scheduling algorithms. SSDsim is written in C, and it has about 15 thousand source lines of C. You can download SSDsim here. If you are using it in your research project, please cite our paper:
"Yang Hu, Hong Jiang, Dan Feng, Lei Tian, Hao Luo, and Shuping Zhang. Performance Impact and Interplay of SSD Parallelism through Advanced Commands, Allocation Strategy and Data Granularity. In the Proceedings of the 25th International Conference on Supercomputing(ICS'11), Tucson, AZ, May-June 2011."
