[KSB] IBM zSeries hardware has for years supported hardware called a Parallel Sysplex. Basically some v-e-r-y e-x-p-e-n-s-i-v-e RAM (along with some goodies like an accurate clock) that provides shared memory between systems that can be physically - perhaps even geographically separated. IBM haven't been able to break the speed of light yet, so a Sysplex can't operate between systems that are very far apart. Beyond my price range for a Christmas stocking stuffer, no matter how neat it is to a geek. -- Bhaskar ___________________________________________________________________________ Philadelphia Linux Users Group -- http://www.phillylinux.org Announcements - http://lists.phillylinux.org/mailman/listinfo/plug-announce General Discussion -- http://lists.phillylinux.org/mailman/listinfo/plug
