Hello, I've successfully installed a software RAID 5 array using kernel 2.2.3 and the 0.90 patch and tools. I have posted the results of this endeavor, including benchmarks at: http://www.idiom.com/~tbyrd/softraid/index.html It might answer some of the questions I've seen here lately regarding which software is required to run the latest tools, and provides links to the latest software and documentation. It also includes Bonnie benchmarks for files sizes ranging from 8 MB to 1.5 GB, and would seem to support earlier statements regarding cache performance variance. (Though these are probably good numbers for estimating CPU/memory/cache performance!) So far, so good! Cheers to the maintainers!!! -Ted
