Texas Memory Systems (TMS) just announced they are providing open source drivers for their RamSan-20: a PCIe based flash solution that offers lower latency and higher bandwidth than a normal Solid State Drive connected via a SAS or SATA connector.
Drivers are available for both Linus and Solaris operating systems, which are traditionally used more than Windows on high-performance servers. TMS is making the source code for the drivers available, enabling others to adopt them in their specific environment. According to TMS, the driver is pretty simple since most of the functionality is integrated into the hardware itself:
Open source drivers are a by-product of the design philosophy behind the RamSan PCIe SSD family. The core functionality of the RamSan PCIe card is in the hardware itself versus other PCIe designs where the driver does most of the work This thin driver offers a simple control paradigm and is easy to port and manipulate as open source. It offers little burden to the host system and creates a nice division of labor between the host and the device allowing the host system to operate to its maximum potential.
Apart from the announcement itself, there is no other information on the driver yet; it’s not publicly available for download, nor does TMS specify the license it will be released under.
