Se 512 GB vi sembrano pochi...
Linux utilizza 3 tabelle di paginazione per la gestione della memoria virtuale. Questo schema limita, per motivi tecnici, l'indirizzamento dei processi su x86-64 a 512 GB.
E' stata proposta l'introduzione di una quarta tabella, per poter arrivare a 128 TB di indirizzi virtuali: http://marc.theaimsgroup.com/?l=linu...8972006944&w=2 Nota: queste tabelle gestiscono gli indirizzi virtuali dei programmi, non la memoria fisica indicizzabile dal sistema. Ad esempio su x86 a 32 bit gli indirizzi virtuali sono 4 GB, e la memoria fisica massima gestibile è 64 GB.
