摘要： Handling ordered writes to a data storage device includes receiving a first chunk of data into slots of a cache of the data storage device and using a hash table to provide a correlation between cache slots containing data from the first chunk of data and locations of a logical storage device of the data storage device. Handling ordered writes may also include maintaining a circularly linked list of pointers to cache slots containing the first chunk of data. Handling ordered writes may also include receiving a second chunk of data into slots of the cache of the data storage device and receiving a message indicating that all data corresponding to the first chunk of data has been transferred to the data storage device. Handling ordered writes may also include, in response to receiving the message, storing data from the first chunk on to the logical storage device. Handling ordered writes may also include using a hash table to provide a correlation between cache slots containing data from the second chunk of data and locations of a logical storage device of the data storage device.

摘要： A primary storage device maintaining recovery data in connection with ordering data writes includes the primary storage device receiving a plurality of data writes, the primary storage device associating data writes begun after a first time and before a second time with a first chunk of data, and the primary storage device associating data writes begun after the second time with a second chunk of data different from the first chunk of data. After completion of all writes associated with the first chunk of data, the primary storage device initiates transfer of writes associated with the first chunk of data to a secondary storage device. The primary storage device maintains a transfer log of data from the first chunk that is successfully transferred to the secondary storage device.

摘要： Managing a cache memory includes providing at least one spillover slot, stored in the cache memory, that contains information about a plurality of cache data slots transferred from the cache memory to a local disk. The spillover slot has a metadata portion with information about cache data slots transferred from the cache memory to the local disk and has a catalog portion with entries that point to different sections of the metadata portion. Each section of the metadata portion corresponding to information about one of the cache data slots transferred from the cache memory to the local disk.
