METHOD, APPARATUS AND COMPUTER PROGRAM PRODUCT FOR MANAGING A MEMORY SYSTEM

The embodiment of the invention relates to a method for managing a storage system, electronic equipment and a computer program product. The method comprises the following steps: in response to a first write operation on a first data block on the persistent storage device, determining whether a cache comprises a first group of data corresponding to the first data block; if it is determined that the cache comprises the first group of data, updating the first group of data in the cache; and adding the first group of data in the cached associated data set as a first record. According to the embodiment of the invention, different types of cache data corresponding to the data blocks can be managed in an associated manner, so that the system performance is optimized. 本公开的实施例涉及用于管理存储系统的方法、电子设备和计算机程序产品。该方法包括响应于对持久性存储设备上的第一数据块的第一写入操作，确定缓存中是否包括对应于第一数据块的第一组数据；如果确定缓存中包括第一组数据，更新缓存中的该第一组数据；以及在缓存的关联数据集中添加该第一组数据作为第一记录。本公开的实施例能够将对应于数据块的不同类型的缓存数据相关联的进行管理，进而优化系统性能。
