Derek Vadala lives in New York City. He works for azurance.com, an open source and security consulting firm that he co-founded. He has been published in SysAdmin Magazine, Linux Journal, The Perl Journal, and The Journal of Linux Technology.
Finally, the book contains a good index and a brief appendix giving links to other sources. A very useful volume that should find favour with anyone who wishes to implement RAID on a Linux system. - Steve Boniwell, HP/Works
