Post courtesy of TechTarget SLAT addresses the inefficiencies associated with looking up virtualized memory addresses in software shadow volumes. The technology exists as a CPU feature: an added translation lookaside buffer (TLB) that contains a real-time updated cache of virtualized memory addresses and their corresponding physical addresses. Virtualization is a core technology for many data centers,
