This is a really key point. I don't like to toot my own horn, but I've done 
EXTENSIVE and EXHAUSTIVE research into this. I built my first Open-E iSCSI box 
in like 2006. The right combination of hard disk, hdd firmware, raid 
controller, controller firmware, motherboard, memory, cpu, nics, hbas.. 
everything is critical and by the time you narrow all of this down and test 
sufficiently and are ready to go into production, you've spent a significant 
amount of time and money. 
Now that said, if you able to piggy back off the knowledge of others, then you 
get a nice short cut and to be fair, the open source software has advanced and 
matured so much that it's really production ready for certain workloads and 
environments.
