Abstract
In a computer system with a hybrid memory architecture consisting of a volatile main memory and a non-volatile main memory, there are provided a segment cleaning method for a storage file system and a memory management apparatus for implementing the same, the segment cleaning method comprising: selecting a victim segment in storage; copying valid blocks in the victim segment to the volatile main memory; and moving the copied valid blocks to the non-volatile main memory. This can effectively overcome cleaning overhead, thereby improving the I/O performance of applications and increasing the lifetime of storage.
