Rack mounted systems.

[Paul Hoffman]

Am attempting to estimate machine room floor space for a fairly
large Beowulf cluster (~500 processors.) Here are my questions
re: loading these into racks: (assume Pentium processors)

- what is the minimum width of a 2-way node? (1U, 2U?)

- how many nodes can reasonably be put in a standard 
  10" rack? i.e. can the rack be fully loaded or is
  some spacing required?

Thanks.
