My name is Marcelo Leal, and I did study at Universidade do Vale do Rio dos Sinos (Unisinos) - RS, where I undertook a bachelors degree in Computing Science.
I do work with IT for more than 20 years (Operating System, Storage and Networking), and more than 10 years with administration and support in Unix, GNU/Linux, and BSD environments. Currently I do work with Cloud Services Architecture (Global and Distributed, Highly Available Solutions).
I did write the books: ZFS Para usuários OpenSolaris, Windows, Mac e Linux - Brasport/2010 (Brazilian Portuguese), and Implementing Samba 4 - Packt/2014 (English).
I was one of the founders of the Porto Alegre OpenSolaris User Group (PoaOSUG). In the OpenSolaris Community, I was a contributor for the Open High Availability Cluster/OHAC Project, and in 2007/2008 I did receive three winning prizes on the OpenSolaris Innovation Awards Program.
In 2009 I did a presentation about Storage HA at the first OHAC Summit in San Francisco/California - USA, and in 2013 about Storage Performance at the SNIA SpeedConf Storage Plumbing and Data Engineering Conference in Santa Clara/California - USA.
