Hi,

Next week, a local SI will provide me a price quote for  a 8-way Opteron 
server based on IWill's
motherboard, IWill's 8-way Opteron server consists two connected 4-way 
Opteron boards in a
5U chassis, there are 32 DIMMs available on the server.  If one can find 
4GB RAM, the server
can accomodate 128GB RAM!  If we can get the budget this year, we will 
see what the performance
of this 8-way server would be.

As a comparison,  we have a HP Superdome with 64 IA64 CPUs and 128GB RAM 
in a 42U rack,
which  costs about 1,300,000 US$ two years ago.  I estimate that the 5U 
8-way Opteron server
with 128GB RAM would cost about 70,000US$  today. 

If your applications requires very large memory,  IWill's H8501 would be 
a very good choice
(http://www.iwill.com.tw/product_2.asp?p_id=90&sp=Y). 8-way Opteron 
server should be able
to realize the full performance potential of Opteron's design.
