I'm using Solaris since 1993. During this time it was named SunOS.
At this time I was an employee of Siemens Austria where a Power System
Control System was developed and used worldwide on the SPARC Hardware running on one or a maxium of 128 Servers. The functionality could be distributed as need.

Now here in our company I'm a "Middleware" Developer for our own products and I'm also administrating our Solaris and Linux boxes. In my area is also the
SunRay installation with a failover group.
Firewall's, e-mail server, VPN, ...
We have currently Solaris 8/9/10 SPARC and Solaris 10 x86 in use.
My Laptop runs currently SCXE Build 91.
