A method and apparatus used in a storage network facilitates the protection of data in, and replacement of, storage devices about to fail before the failure happens. In a network that includes a set of storage devices organized as a non-redundant (for example RAID 0) array, a storage device about to fail in the non-redundant array can be replaced by another storage device, typically from a pool of spares. The method includes detecting a condition of a first particular storage device in the non-redundant array. Conditions which are detected according to various embodiments indicate that the first particular storage device is suffering events indicating that it is likely to fail, or otherwise suffering from reduced performance. The conditions are detected for example, by the receipt of a signal from the storage device itself, or by the monitoring of statistics concerning the performance of the storage device. The method further provides for selecting a particular spare storage device, which can be used in place of the first particular storage device. In response to detecting the condition, data stored in the first particular storage device is migrated to the second particular storage device, and the second particular storage takes the place of the first particular storage device in the non-redundant array. The first particular storage device can then be gracefully removed from the network without loss of service to the clients computers.

Systems and methods are presented to allow or prohibit any or all services between a network and a node in the network based upon the geographic location and rate of travel of the node. One exemplary application is for the prevention of texting while driving. For example, in FIG. 1: Typical Wireless Communications Network, the location and rate of travel of the mobile station, (MS), 140, can be determined from the use of Global Positioning System, (GPS), information received by the MS, (140), and transmitted to the network. The MS, (140), may have any or all of its subscriber services enabled or disabled by the network based upon the speed that the MS, (140), is traveling and / or its geographical location. Other methods are possible to determine the location and rate of travel of a mobile station as well. In the preferred exemplary embodiment, it is possible for a mobile wireless network to determine the location and speed of an MS. The preferred exemplary embodiment will disallow the operation of features like text messaging or speaking on the mobile phone, when an individual is driving over a range of predetermined speeds. Additionally, this embodiment would disallow the operation of similar features in specific locations, like schools, and jails. In this embodiment it is also possible to allow any MS to access predetermined destinations for emergencies, like 911, at any time. This embodiment also allows services at otherwise forbidden speeds and / or locations to specific MSs or end-users. In this way public safety officials are not restricted and “hotspot” service can be offered on buses or trains. This enhancement to the network would permit more fine-grained control over where and when services can be allowed.

A communications architecture utilizes modules arranged in a daisy-chain, each module supporting multiple input and output ports. Point-to-point links are arranged so that a first output link of each of multiple modules connects to the next module in the chain, and a second output link connects to a module after it, and inputs arranged similarly, so that any single module can be by-passed in the event of malfunction. Multiple chains may be cross-linked and / or serviced by hubs or chains of hubs. Preferably, the redundant links are used in a non-degraded operating mode to provide higher bandwidth and / or reduced latency of communication. The exemplary embodiment is a memory subsystem in which the modules are buffered memory chips.

A storage system includes a RAID adapter, disk array switches, sub-processors, and hard disk drives. A disk-related operation is initiated in the RAID adapter which dispatches a command to a disk array processor (or sub-processor) in an enclosure for the processor to perform the operation on one or more drives. The adapter may dispatch the command to a processor in a single enclosure through a disk array switch or to processors in multiple enclosures through switches in upstream enclosures. The adapter is then free to perform other functions. The processor commences the specified operation on one or more selected drives. Upon completion of the operation, the results are transmitted by the processor and received by the adapter. Offloading the task to the distributed sub-processors reduces the burden on the RAID adapter, reduces system bandwidth usage, and enables access to other drives to be maintained.

A system and method are disclosed that reduce collisions on a wireless medium shared by devices associated with a wireless network, thereby improving throughput on the wireless medium. For some embodiments, a first device reserves access to the medium for a first interval, and then grants medium access to a second device for a remainder of the first interval. If the second device transmits data during the remainder of the first interval, medium access is maintained with the second device and then the second device is prevented from contending for medium access during a subsequent contention period. Otherwise, medium access is returned to the first device and the second device is allowed to contend for medium access during the contention period.
