We have tested it using 24 nodes as NSDs servers, using a partition of 
the internal IDE (PATA) disk as storage.

It worked very well. The type of the disk doesn't hurt the performance 
and the load of the nodes are perfect balanced. It is a very good 
product, very viable in technical terms. It does a better work than 

The main problem with it is the IBM licensing type... At the time we 
tested it, the IBM guys told us it is licensed by CPU, and was very 
expensive. After that, they told us they have changed this licensing, 
but doesn't explain what changed.

If anyone wanna use a parallel file system, acquiring a commercial 
solution must evaluate Panasas. It is a hardware/software solution and 
is very robust and easy to deploy.
