This website aims to be the starting point for people wondering how to use and manage and harware RAID HBAs on GNU/Linux.
There are many vendor and model of hardware controllers. Some are fully supported on Linux, some are nearly unusable.
Having a kernel driver for the card is the first thing needed. However, once it's done the sysadmin needs to be able to manage, and of course to keep in touch with the disks status to be able to replace a failed disk as soon as possible.
This aspect is really important and we will try to tell you most of all we know about opensource and proprietary tools used to report card and disks status.
Please notice the information available on this site have been provided by sysadmin on their free time in the hope it could be useful.
There's of course no warranty about all what's written or downloadable here. However we do our best to have fully verified informations.
Please use the ticket system to report us any issue and support us by clicking the "donate button" at the bottom of the page

rkt (pronounced "rock-it") is a CLI for running app containers on Linux. rkt is designed to be composable, secure, and fast.
Some of rkt's key features and goals include:
- First-class integration with init systems (systemd, upstart) and cluster orchestration tools (fleet, Kubernetes)
- Compatibility with other container software (e.g. rkt can run Docker images)
- Modular and extensible architecture (network configuration plugins, swappable execution engines based on systemd or QEMU/KVM)
Manage a cluster of Linux containers as a single system to accelerate Dev and simplify Ops.
Tomb is an 100% free and open source system for file encryption on GNU/Linux, facilitating the backup of secret files. Tomb is written in code that is easy to review and links commonly shared components.
Tomb generates encrypted storage folders to be opened and closed using their associated keyfiles, which are also protected with a password chosen by the user.
A tomb is like a locked folder that can be safely transported and hidden in a filesystem; its keys can be kept separate, for instance keeping the tomb file on your computer harddisk and the key files on a USB stick.
Tomb is a simple tool to manage encrypted storage on GNU/Linux, from the hashes of the dyne:bolic nesting mechanism.
Hinter diesem Titel verbirgt sich der bemerkenswerte Vortrag des Kieler Psychologieprofessors Dr. Rainer Mausfeld. Es lohnt sich, diesen Vortrag anzuhören/anzuschauen, und es empfiehlt sich, Freunde, Nachbarn und Familie zur Diskussion einzuladen. Mausfeld nimmt uns, soweit noch vorhanden, die letzten Illusionen zum Zustand der Demokratie, zum Missbrauch unserer Sympathie für Demokratie und zur Gewalttätigkeit unserer westlichen „Werte“gemeinschaft. Desillusionierung schadet nicht. Außerdem: Der Vortrag ist aktuell – wegen Griechenland, wegen der spürbaren Bereitschaft zu militärischen Auseinandersetzungen, wegen der alltäglichen Gewalt. Wir bieten Ihnen nicht nur die Links zum Vortrag, auf die anschließende Diskussion und auf ein Interview mit Professor Mausfeld bei Phoenix – zum leichteren und nachhaltigen Umgang mit dem Vortrag bieten wir hier [PDF – 352 KB] auch noch eine Zusammenfassung und Handreichung, die die NachDenkSeiten-Leserin S.H. dankenswerter Weise zusammengestellt hat
Apache ZooKeeper is the coolest technology I recently came across. I found it when I was doing a research about Solr Cloud features. I got very impressed by Solr’s distributed computing. You literately have to fire a new instance and it will automatically find its place in “the cloud”. It will assign itself to a particular shards and it will make a decision to become a leader or a replica. Later you can query any of the available servers and it will find you all required data even if it’s not on that server. If some of the servers fail the service will continue to work. Very dynamic, very clever, very cool.
