Abstract
Techniques are disclosed relating to storing translations in memory that are usable to access data on a recording medium. In one embodiment, a request is sent for a memory allocation within a non-pageable portion of a memory in a computer system. Responsive to the request, allocated memory is received. Translations usable to map logical addresses to physical addresses within a storage device are stored within the allocated memory. In some embodiments, the translations are usable to access an area within the storage device used to store pages evicted from the memory. In one embodiment, a size of the memory allocation is determined based on a size of the area. In another embodiment, a size of the memory allocation is determined based on a size of a partition including the area. In some embodiments, the storage device is a solid-state storage array.
