In my experience, I would agree with that. Normal maintenance contracts cover three years, and of course vendors will extend them. At about that timeframe though: Parts become more difficult to source The OS which was int he original install is probably getting old - so do you re0image the whole thing, or consider its replacement? Disk drives are larger - so the storage is looking small now The server room investment in fit-out, electrical feeds and cooling is still functioning - you have to start asking if the floor space is better used on another system. Fit-out in a server room will outlast several generations of HPC kit. Class, discuss The contents of this email are confidential and for the exclusive use of the intended recipient.
