Paul, "e elegance and power of this OS can't be underestimated. However, you must ask yourself - what market forces are responsible for this OS (Galaxy/VMS) NOT garnering significant market share over the years? Maybe others have figured out that they can deploy a ton of "industry standard" servers far cheaper than the ELEGANT solution, and come up with an acceptable performance. Industry Standard solutions - high volumes - economies of scale - that's where the growth is." Good questions and points. What was left out in my description is that Galaxy was actually an outgrowth of what was coming down the pike. The Alpha 8400 (max 14 CPU) was announced in April 1995 and engineering in the following months surveyed customers to get a feel for the next large box... feedback to Unix and VMS engineering described what they could expect and they set about modifying their OSes accordingly. By December 1996 VMS engineering was already describing Galaxy. Galaxy really wasn't/isn't effective until this box came along (the GS320 aka Wildfire). That was the target hardware. This was a very productive time in VMS with many new (patenable) ideas being put into action. Galaxy is very innovative in that everything is under software control and that is why a single CPU can leave an instance and join another while all others move boards at a time between domains. But that is only a peak at one aspect. Much of what is to come is very powerful. Mostly moving OS components into shared memory gains great scaling. DLM and QIO Server .. where DLM is the Lock Mananger and QIO Server is the MSCP follow-on.. I/O is dispatched via or through shared memory. All the ins and outs of what that means is yet to be determined (i.e. we will know more when it ships, also know exactly how it works when the Internals and Data Structures .. IDS shows up explaining Galaxy internals). Regarding performance and industry standard servers comparing to something like this? No way. A RamDisk in shared memory in the next box (according to my modest calculations) will be capable of at least 20 GByte/second read and write speed... What am I basing that on? The next box does 100 GByte/sec aggregate memory bandwidth... but that is always best case scenario... I'm picking a modest 20% of that. It may be more it may be less... but you get the idea. When it comes to I/O in the near future, you haven't seen anything yet. Rob
