pcap2ds is a tool that converts tshark pcap traces to HP’s DataSeries format. Also includes a ds2xml tool that converts DataSeries to a readable XML format.
pvfs2-osd is a fork of PVFS2 to support OSDs as storage bricks. It includes the optimizations from the “Optimizations on a Parallel File System Integrated with Object-Based Storage Devices” paper from IEEE CLUSTER 2013.
osc-osd is the Ohio Supercomputer Center OSD implementation whose maintenance has since been taken over by Panasas at open-osd.org. This fork includes SNSL modifications to support unimplemented commands, multithreading, and active storage.
The NetFPGA Aurora Switch enables the connection of multiple NetFPGA boards into a unified non-blocking switch using the Aurora SATA connections as interconnect. The architecture is described in “Scaling the NetFPGA switch using Aurora over SATA” paper from the 2010 NetFPGA Developers Workshop
pvfs2fuse is a patch to PVFS to add a FUSE interface to the PVFS file system. Using FUSE opens up PVFS to many more clients including MacOS and BSD.
dTrace is a lightweight disk tracing tool which captures all requests on a particular disk from any file system. The tool works with IDE disks only.
SFUSE is a series of modifications to FUSE to allow stackable filesystems in user space. Currently all work is based on Linux kernel 2.6.24 (link) The SFUSE architecture is described in the “User space storage system stack modules with file level control” paper from the 2010 Annual Linux Symposium.
