Less known Solaris features: SamFS
Tuesday, March 25. 2008
Pheewww ... iīve finalized my SamFS tutorial, a long text. SamFS is the hierarchical Storage Management Filesystem from sun. Several new concepts, so you have to explain some theory before getting to the shell:
- Part 1: Introduction.html
- Part 2: The theory of Hierarchical Storage Management
- Part 3: The Jargon of SamFS
- Part 4: Installation of the packages
- Part 5: Configuring a SamFS filesystem
- Part 6: Configuring disk archiving
- Part 7: Working with SamFS
- Part 8: Usecases and future directions
- Part 9: Conclusion
Less known Solaris Features: SamFS - Part 9: Conclusion
Tuesday, March 25. 2008
Okay, this was a rather long tutorial and i didnīt even talked about the configuration of tape devices. As i told you before: Only the toes in the atlantic ocean. But i hope, i gave you some insight into a somewhat unconventional topic and a capability of an optional part the Solaris Operating Environment. I assume, with the opensourcing of SamFS we will see a much more widespread use of it.

Less known Solaris Features: SamFS - Part 8: Usecases and future directions
Tuesday, March 25. 2008
Okay, after all this configuration. How can you use it? Well, the most obivous usage of SamFS is Archiving. And many customers use it for exactly this task: Archiving audio, archiving video, archving eMails, documents, xrays, satellite images, simulation data, data of large experimental system. Everything thatīs worth to be stored for a long long time. Thatīs the job, it was designed for.

Now weīve configured a file system and we set up the archiver for it. Now letīs use it.

Less Known Solaris features: SamFS - Part 5: Configuring a SamFS filesystem
Monday, March 24. 2008
Okay, now we can configure our first filesystem with SamFS.

Less Known Solaris features: SamFS - Part 4: Installation of the packages
Monday, March 24. 2008
Itīs quite easy to install SamFS. Itīs just installing two packages and answering some questions.

Less known Solaris Features: SamFS - Part 3: The jargon of SamFS
Monday, March 24. 2008
As usual, this technology has itīs own jargon. Thus i will start to define the most important words at first.

Less known Solaris Features: SamFS - Part 2: The theory of Hierarchical Storage Management
Monday, March 24. 2008
I think, i should start with the theory of Hierarchical Storage Management(HSM). The technology of managing data and their position on different media isnīt really a widespread feature for most adminstrators. Thus this introduction will be a quite long one.

Less known Solaris Features: SamFS - Part 1: Introduction
Monday, March 24. 2008
Okay, this is tutorial isnīt really about feature of Solaris itself. But the feature of this tutorial itīs deeply coupled with Solaris. Thus you can view it as an optional part of Solaris. This time i will dig into the installation and configuration of SamFS. But a warning, SamFS is a feature monster. This tutorial is equivalent to put your toes in the Atlantic ocean, but when i saw the annoucement of the open-sourcing of SamFS i thought, itīs time to write this document. In addition to that, it was a nice way to make a reality check on a thought game, iīve made some months ago.
SamFS/QFS opensourced
Tuesday, March 18. 2008
Some weeks ago, i wrote about about an idea to use hierarchical storage management at home. One important part of this idea is now available as opensource. Yesterday Sun opened the code of SamFS/QFS under the CDDL licence. SamFS is an fully hierarchical filesystem to implement tiered storage. QFS is the filesystem part of it (you can use QFS alone) and has some really interesting capabilities like seperating the metadata from other data on fast disks (SSD for example) or the multiple reader/multiple writer capability to use a SAN filesystem from multiple systems in parallel.
Thoughtgame: Leveraging ZFS, iSCSI and the Thumper with SamFS
Monday, March 12. 2007
Itīs a thing i will try out in the next few days. Can i use ZFS, iSCSI and Thumper to improve the already excellent SamFS HSM filesystem? Can i solve the problem of migration in storage media life cycle managment en passant?
