[comp.databases] File Management Systems

I am looking for a file management system that supports basic file 
handling capabilities as well important index structures (hashing, 
B(+)-trees, etc), runs in a UNIX environment with a multiserver 
configuration, and is reasonably efficient. An important requirement 
is that the system should allow low level access (at the level of 
physical blocks from disk) to data. The system c-tree Plus was 
suggested to me. However, after some enquiries I learned from the 
c-tree people that the UNIX version of their product is not yet ready 
for marketing, while their brochures claim its availability and even 
quote a price! I would much appreciate information on a file management 
system that meets the above requirements, the company marketing it, 
and reference literature. Of course, info on any "free" systems along 
with the sites from which they can be ftp'ed would be more than 
appreciated. Please send email to: 

               laks@maxwell.concordia.ca 
                      OR 
               laks%maxwell.concordia.ca@relay.cs.net 

Thanks a lot in advance!
