One of the most popular SAS 6.0gbps/ SATA III controllers for enthusiasts is the IBM M1015. In its native form, it is a very capable host bus adapter (HBA) based on the LSI SAS2008 chip. With the low price on places such as ebay (see here for an ebay search for the M1015) and an enthusiastic community that has learned to unlock many features, it has quickly become a go-to choice for low-cost SATA III connectivity. This series of articles was written by Pieter Schaar perhaps best known as the one behind laptopvideo2go.com. He has been a regular contributor in the STH forums and has been detailing his learning in threads such as these. I do want to note that these modifications are not endorsed by this site, LSI, IBM or others and the information herein is purely for educational purposes.

Die Diskussion ist fast so alt wie die IT: Wie viel Dokumentation benötigt ein System? Während es für den Kunden oft nicht genug sein kann, möchte der typische Entwickler am liebsten ausschließlich Code erzeugen. Eine leicht falsch interpretierbare Aussage aus dem Agilen Manifest zum Thema Dokumentation hat die Diskussion noch weiter aufgeheizt. Guter Rat scheint teuer. Aber so schwierig ist es letztlich gar nicht und ein wenig Systematik bei den Dokumentationsarten sowie gerade die agilen Prinzipien helfen, Inhalt und Umfang einer guten Systemdokumentation zu optimieren. In diesem Artikel werden zwei einfache Werkzeuge vorgestellt, die helfen, Dokumentation nicht mehr auf “Verdacht” zu erstellen, sondern zielgerichtet nach Sinn und Wert zu optimieren.

Michael DeHaan started the Ansible project because he realized that past attempts to automate IT had only moved complexity into other areas. Instead of making the lives of developers and sysadmins easier, we were now managing the management systems with a messy combination of custom code, heavyweight agents and point solutions. And none of these tools were built for the cloud. There had to be a simpler way.
