Abstract: A system and a method for performing a warm shutdown and restart of a buffer pool. The buffer content, including pages and control structures associated with these pages, is partitioned into blocks, where block is saved to a disk as a sequential file. The size of each block is selected to provide an optimal I/O efficiency during buffer pool shutdown and restart operations. Blocks can be saved simultaneously using a plurality of writer threads. During restart of the buffer pool, the control information is read from the disk and restored to the buffer pool using reader threads. The buffer pool may be made available for reference to pages while the reader threads are enabled to read the saved information by blocks, to facilitate a more rapid restoration of information in the buffer pool.
