Thank you for all of your assistance. I would like to move to being able to build a cheap san-like storage area for a DB, I don't know how well it would work but I'd like to try it anyway since things like HP MSA's are hugely expensive. I like these suggestions of filling a second box and connecting this to the 1st box using these expanders and port replicators. I don't really need as fast as I can get as this is not a high-use DB backend or many user file server. A few users here and there but nothing that worries me about the bottleneck caused by these replicators. This way is ALOT better then my system of trying to export iscsi disks or something like that. This way I can add create a second box then have a cable into an expander or replicator on the 1st box, a 3rd box could then be added to the expander/replicator at a later date. There is a limit on how far this could go realistically, but I like this way. I could go further by adding SSD's for the L2ARC and ZIL if I wanted to. I found zfsbuild.com to be a quite nice site/blog Thanks for all your help
