Hi Dan,
Running on SME 5.6, I downloaded the 3dm utility from Shad's website and installed it but not the driver from Shad. In my attempts, using Shad's drivers appears to cause boot problems with my setups. So, I've decided to stick to the drivers that comes with SME 5.6. This did not seem to impact the 3dm utility (that I've noticed anyway).
The 3dm will let you view the RAID status via a web browser and you can also configure an e-mail address to send warnings and alerts to.
