Abstract: A coding scheme for coding “code constructs” (for example, alphanumeric characters) into “bit sequences,” where at least one of the code constructs is assigned at least two different bit sequences (that is, a first bit sequence and a second bit sequence). This is sometimes referred to herein as “alternative codings for a single code construct.” In some embodiments, at least one of the alternative codings includes bits that can be used for error detection and/or correction. In some embodiments, the code scheme will be similar to a pre-existing code scheme that does not have alternative codings for a single code construct so that the alternative-codings coding scheme is back compatible with data encoded under the pre-existing coding scheme.

Abstract: A mechanism is provided in a data processing system for elastic data storage management in a storage network. A data storage system manager in the data processing system monitors remaining free space of a plurality of data storage systems. The data storage system manager determines a rate of change of remaining free space of each data storage system. Responsive to determining that the remaining free space or rate of change of remaining free space of at least one data storage exceeds a threshold, the data storage system manager determines an amount to expand or shrink a given data storage system in the storage network. The data storage system manager configures data storage allocation to expand or shrink the given data storage system by the determined amount.

Abstract: A mechanism is provided for object-based storage management. A detection is made of an event being performed on or by the object. A determination is made as to whether the event meets with one or more rules in a set of rules that identify a backup or replication needing to be performed. Responsive to determining that the event meets with one or more rules in the set of rules that identify the backup or replication needing to be performed, an indication is made in a backup/replication field in metadata of the object that the backup and/or replication of the object needs to be performed. The indication in the backup/replication field in the metadata of the object causes one or more portions of the object to be backed up and/or replicated.

Abstract: A mechanism is provided a data processing system for protocol servicing in network-attached storage. A protocol service executing in the data processing system in a clustered file system establishes a high priority recovery thread. The high priority recovery thread monitors health counters that count total requests in and total requests out for a client accessing a network-attached storage device via the protocol service. The high priority recovery thread determines a category of health of the protocol service based on the health counters. The mechanism takes corrective action based on the category of health of the protocol service.
