    Abstract: Avoiding encryption in a deduplication vault. In one example embodiment, a method may include analyzing an allocated plain text block stored in the source storage to determine if the block is already stored in the deduplication storage, in response to the block not being stored, encrypting the allocated plain text block and analyzing the encrypted block to determine if the encrypted block is already stored in the deduplication storage, analyzing a second allocated plain text block stored in the source storage to determine if the block is already stored in the deduplication storage, in response to the block already being stored, avoiding encryption of the second allocated plain text block by not encrypting the second allocated plain text block and instead associating the location of the second allocated plain text block in the source storage with the location of the duplicate block already stored.

    Abstract: Techniques to backup collaboration server data are disclosed. An indication to begin backup of a collaboration server dataset is received. An associated directory is walked in a prescribed order to divide the dataset into a prescribe number of approximately equal-sized subsets. A separate subset-specific thread is used to back up the subsets in parallel. In some embodiments in which the collaboration data is stored in multiple volumes, a volume-based approach is used to back up the volumes in parallel, e.g., one volume per thread. In some embodiments, transaction logs are backed up in parallel with volumes of collaboration data.

    Abstract: A method and an apparatus for reducing a read latency are provided. The method includes: when one or more flash chips corresponding to a read command are in a busy state, setting data read from the one or more flash chips in a busy state to wrong data; obtaining, according to the wrong data and data read from other flash chips, reconstructed correct data, and reporting the correct data. By using the present invention, data read from a flash chip is set to wrong data, and reconstructed correct data is obtained according to the wrong data and data read from other flash chips. In this way, when the flash chip is in a busy state, it can be avoided that a read operation is blocked by an erase operation or a write operation, thereby effectively reducing latency and improving a performance of a storage system.

    Abstract: An information handling system and method allows implementation of fault-tolerant storage subsystems using multiple storage controllers not themselves originally designed to support the redundancy of such fault-tolerant storage subsystems. In accordance with one embodiment, uncommitted data is efficiently and rapidly replicated across multiple commodity storage controllers, enabling faster and less expensive fault-tolerant storage subsystems. A redundant storage controller system using non-redundant storage controllers can improve the efficiency of data replication while providing failure protection against controller failure. A redundant storage controller system using non-redundant storage controllers and shared memory commonly accessible to the storage controllers can be enhanced to replicate data within host memory regions to protect against non-volatile memory failure. In accordance with at least one embodiment, an efficient data replication mechanism can be provided between storage controllers using off-the-shelf hardware.

    Abstract: Avoiding encryption of certain blocks in a deduplication vault. In one example embodiment, a method of avoiding encryption of certain blocks during a backup of a source storage into a deduplication vault storage may include analyzing each allocated plain text block stored in a source storage at a point in time to determine if the allocated plain text block is already stored in the deduplication vault storage. If the allocated plain text block is not stored in the deduplication vault storage, the block may be encrypted and the encrypted block may be analyzed to determine if the encrypted block is already stored in the deduplication vault storage. If neither the allocated plain text block nor the encrypted block is already stored in the deduplication vault storage, the encrypted block may be stored in the deduplication vault storage.
