I've designed and helped implementing the following
production systems, all of which are still in service:
- * **SugarLabs**'s Internet infrastructure -- I'm coordinator
+ * **SugarLabs's Internet infrastructure** -- I'm coordinator
of the [[http://sugarlabs.org/go/InfrastructureTeam | Infrastructure Team]],
taking care of 8 machines hosted at various colocation facilities, running
development and support services for a large community.
- * **[[http://fsf.org/ | Free Software Foundation]]**'s virtualization infrastructure --
+ * **[[http://fsf.org/ | Free Software Foundation]]'s virtualization infrastructure ** --
I've been the fall system administrator intern in 2009. My main job was to set up and
evaluate a **high-availability virtualization cluster** with 2 nodes based on
[[http://www.xen.org/ | XEN]] and [[http://www.drbd.org/ | DRBD]].
act as VoIP PBX and secondary slave for many (but not all) of
##trinity##'s services.
- * ** http://www.fieremostre.it/ ** - A cluster of 4 RedHat
+ * ** [[http://www.fieremostre.it/ | Fieremostre (Milan)]] ** - A cluster of 4 RedHat
servers, two web front-ends and Java appservers and two
database and filesystem back-ends with SCSI RAID5.
Fully managed remotely, including power fencing and
robotized tape juggler.
- * I've configured and installed a cluster of 5 nodes on
- blade CPU boards with shared fiber-channel RAID storage.
- I used a pre-release of RedHat's Advanced Server product
+ * In 2003, I configured and installed a cluster of 5 nodes on
+ blade CPU boards with **shared fiber-channel RAID storage**.
+ I used a pre-release of **RedHat Advanced Server**
to implement a shared storage pool of 1.5TB with GFS1.
The system initially went to production without the GFS
pool because of reliability concerns with this new
technology.

- acting as a gateway and file server for a security ring.

-My philosophy is using mainstream hardware whenever possible
-and concentrate most services on few physical systems.
-The savings in cost can be used to increase availability and
-performance through redundancy. This strategy leads to
-data-centers that are easy to understand and maintain, while
-at the same time scaling up much better than
-traditional asymmetrical solutions (like web server,

Being particularly fond of the UNIX culture, I tend to keep
my systems as open as possible while at the same time very secure.
