I guess the only hope is to find pin-compatible Xeons that are 64bit to replace what is a large chassis with 24 slots of disks that has specific motherboard form-factor, etc. We have 6 of these things from a government grant that must be used for the stated purpose. So, yes, we can buy product, bu

Yup, your probably running up against the limitations of 32-bit kernel addressability. We are currently very conservative in this environment, and so tend to end up with a small cache as a result. It may be possible to tweak things to get larger cache sizes, but you run the risk of starving out
