I have bad experience of the Promise M500i.. loosing configuration on
reboot, whole array crashing when one drive fails, locking problems crashing
the UI (or blocking the use of it), general feeling of being extremely
version 0.0.1. 

I have been using Equallogic PS-series arrays, and they are excellent: fast,
easy to use, stable, reliable and Equallogic has great support.. Promise has
really sucky support (based on my experiences). But of course the price tag
of Equallogic is something different compared to Promise.. You get what you pay for..

If you wanna play with DIY solutions try Linux iSCSI Enterprise Target.. and
maybe openfiler.
