More Information
Summary:Examples include compressed pages having data and compression metadata. Some examples include receiving a write request containing write data, storing the write data in data cache, and applying a page fit process to the write data. In some such examples, a virtual page table entry in a virtual page table may be generated for the processed write data. The virtual page table entry may include a compression index and a page address. An inline compression of the processed write data may be performed to compress and store the processed write data in a compressed page at a location associated with the compression index. In some examples, the compressed page may include a compression metadata having a reference count, a compressed page offset, and a virtual page address.
