The averages of these historical values of the performance parameters at each time interval of the day form the basis of comparison with the captured current values of the rogue user. Once a potential intruder has been identified from his Media Access Control and Internet Protocol addresses, the algorithm of the present invention is used to localize the suspect into the island which has the substantially similar performance characteristics as the rogue user's computer.

Methods and apparatus provide a lock resizer for resizing of a lock array of a lock-based concurrent hash table. The lock resizer provides a data structure with memory locations which is apportioned into buckets that contain a plurality of the memory locations. It is understood that the data structure can dynamically add new memory locations. The lock resizer further provides a location lock for each distinct memory location and a bucket lock for each distinct bucket. A resizing flag can reference a thread to indicate whether or not the thread is resizing the amount of locks. Upon detection of the existence of a policy condition, the lock resizer resizes the amount of location locks and/or bucket locks in order to create new location locks and new bucket locks, thereby ensuring that as new memory locations are added, all buckets can contain up to a fixed number of memory locations.

Methods and systems are provided for minimizing disruptions when host data on a source logical unit is migrated onto a target logical unit. I/O requests are managed in a particular order during various states of the migration. After the target logical unit is synchronized with the source logical unit and before a commitment to the target logical unit is made, the target logical unit can be evaluated. At that point, the migration can be aborted. During the evaluation of the target logical unit, I/O requests that were directed to the source logical unit are redirected to the target logical unit and I/O requests that were directed to the target logical unit are redirected to the source logical unit. The disclosed methods and systems are equally effective at enabling less disruptive virtualization of a source logical unit as a target logical unit.

A remote copy network realizes low-cost multi-hop remote copying. Remote copying is executed via a remote copy network (RCN) having a source edge device connected to a source storage and a target edge device connected to a target storage. Because the RCN is a network provided by a network business, a user having a storage device can execute remote copying without owning or managing the RCN. The source edge device receives remote copy I/O from the source storage, creates a log entry to which a sequential number is added, and sends the log entry to a target edge device. The target edge device acquires the remote copy I/O from the received log entry, and sends the remote copy I/O to the target storage in the order of the sequential number.

A common access ring (CAR) architecture that supports multiple masters and slaves is provided. One or more masters may make a request on the ring at the same time, such that multiple transactions are simultaneously pending. Moreover, multiple masters may simultaneously make a request to the same slave. However, each master cannot make more than one request at a time, and must wait until a current request is completed before making another request. The ring architecture ensures that no more than one request arrives at a slave at any given time. If a request arrives while a slave is processing a previous request, the arriving request is not serviced, and the master that originated the arriving request is asked to retry the request at a later time. Atomic shadow-write operations are supported by including all shadow registers in a dedicated sub-ring of the CAR architecture.
