The (soon to be released) MySQL cluster software docs use a "sample" cluster node configured with Dual Xeons and 16GB of ram. MySQL has never been able to use more than 2 gigs of system memory (on 32 bit platforms.) With MySQL Cluster, will MySQL finally start using the memory paging trick Oracle and others have been using for years? Otherwise, what is the point of having 16 gigs of ram for one MySQL server?
Disk cache. Tables which MySQL doesn't have in its own buffers but which nevertheless are frequently accessed will already be in RAM, and therefore faster to access.
Even so, you'd probably do better with a 64 bit processor with that amount of memory.
