摘要： Provided are a computer program product, system, and method for managing data in a first cache and a second cache. A reference count is maintained in the second cache for the page when the page is stored in the second cache. It is determined that the page is to be promoted from the second cache to the first cache. In response to determining that the reference count is greater than zero, the page is added to a Least Recently Used (LRU) end of an LRU list in the first cache. In response to determining that the reference count is less than or equal to zero, the page is added to a Most Recently Used (LRU) end of the LRU list in the first cache.

摘要： Systems and methods are provided that confront the problem of failed storage integrated circuits (ICs) in a solid state drive (SSD) by using a fault-tolerant architecture along with one error correction code (ECC) mechanism for random/burst error corrections and an L-fold interleaving mechanism. The systems and methods described herein keep the SSD operational when one or more integrated circuits fail and allow the recovery of previously stored data from failed integrated circuits and allow random/burst errors to be corrected in other operational integrated circuits. These systems and methods replace the failed integrated circuits with fully functional/operational integrated circuits treated herein as spare integrated circuits. Furthermore, these systems and methods improve I/O performance in terms of maximum achievable read/write data rate.

摘要： Methods and systems for reading from and writing to a distributed, asynchronous and fault-tolerant storage system. The storage system includes storage nodes communicating with clients. The method includes a first client writing an object to the storage system and a second client reading the object from the storage system. For the first client, previous transient metadata relating to a previously written version of the object is retrieved and a new version of the object together with new transient metadata is stored. For the second client, a set of transient metadata from a third set of nodes amongst storage nodes is retrieved, a specific version of the object as stored on the storage system is determined, and a specific version of the corresponding object from a fourth set of nodes amongst storage nodes is retrieved. Two sets of nodes amongst all sets have at least one node in common.
