I just finished creating, testing and uploading a patch for the rxdsk 1.4 module to build on 2.6.18 kernels (for those still using Red Hat and CentOS 5.x). Another update is that I posted some new performance data on the performance page.

This may be one of the last patches I release for the 2.6.18 kernel as this may be one of the last releases in the 1.x series of the RapidDisk solution. I am currently focusing most of my time and efforts on the 2.x series which adds a lot of new features and functionality which would make it nearly impossible for me to backport to earlier kernel releases.

Recently Jens Axboe posted an update to his fio benchmarking utility which is currently used by Fusion I/O to benchmark their Flash-based SSD solutions. It is currently in version 2.0.3 which is what I used for the tests. You can download the utility here: http://freecode.com/projects/fio

It was the first time I had used the utility and it was extremely simple to build, install and use. I was excited to see my module operate as fast as 700 MB/s and on faster hardware as much as 900 MB/s to over 1 GB/s!!! I can only imagine how much faster it would be on newer 64-bit architectures.

Note that I define the I/O profiles under each respective section and compare it to my local magnetic SATA disk drive.
