Thanks Steve.  I was starting to suspect we had been sold a pup.  
Confusing thing is, I cannot find any reference to the Adaptec model 
AIC-8110 as to what it actually is.  Probably soem OEM chip.  I assume 
I will be speaking to the supplier.  I was assured it was hardware 
RAID.  Life is a learning process.

So, it seems that software RAID is the only real choice with this 
system.  Anyone able to give me suggestions as to whether this is a 
sensible option?  The system will mainly be serving pages, not updating 
databases etc.
does the linux software raid support hot swap?  this hardware claims to 
but not sure what happens if the raid is not enabled.  It will be 
running Debian Sarge 2.6 kernel.
