For years I've been using OpenFiler on a homebrew box (GB RAM, Intel 
Core2Duo) as my NAS.  Nice, simple, stripped down Linux appliance that 
serves my needs, is open source, and is supportable.  Use that to 
support my OracleVM and RAC lab and demo boxes.  The OracleVM (based on 
XEN, and also free, downloaded from Oracle) runs on Dell Precision 490s 
and T5500s, which can be picked up at a pretty reasonable price, and 
it's all connected using Intel dual or quad GB Nics and 2xLinksys 
SRW2024 GB switches.

For GIS, Oracle Locator provides storage for nearly all commercial and 
open source GIS product, Oracle Spatial (my personal specialty) provides 
many of the analytic functions provided by GIS vendors, Oracle MapViewer 
provides a basic visualization tool.  No input/update tool though.  
Locator is available in every edition of 10gR2 and 11gR2 including 
Express Edition, and Spatial extends that included in Personal Edition, 
or as an option in Enterprise Edition.

A lot of people overlook Personal Edition.  It's a singe-user 
developer's DB, includes all features and enteprise edition options 
except RAC and EM related extensions.  Only available for Windows, 
though.  Target community - developers who actually want to have support 
and perhaps develop things 'right'.
