In past years I have been using two IBM x330 machine to run QNX as remote access real-time servers. Unfortunately one is
 down recently, so I have to buy a new server to replace the dead one. Now I have some questions:

 1. Multicore CPU support: Now hardly find a server machine with single core CPU. I am not sure about the ability of 
QNX4 multicore support?

 2. Some concerns about the drivers of network card, video card.  Any suggestion about server machine selection from IBM
/HP/DELL. I think one entry-level server shall be good enough to run QNX4, such as:
        - HP ProLiant DL120 
        - IBM IBM System x3250
        - DELL PowerEdge R210 
Anyone has some recommendation about this?

Thanks in advance!
