摘要： A method for throttling host throughput in a computer storage subsystem is provided. The host throughput is compared to a throughput limit for a predetermined time period. If the host throughput exceeds the throughput limit during the predetermined time period, an input/output (I/O) delay is set equal to the remainder of the predetermined time period, and the delay is implemented for an associated storage device of the computer storage subsystem.

摘要： A method for controlling the throughput in a communications channel between a host and its storage subsystem is disclosed. A determination is made whether or not a total throughput value is greater than a predetermined maximum throughput value. If the total throughput value is greater than the predetermined maximum throughput value, a delay is applied to the communications channel. If the total throughput value is not greater than the predetermined maximum throughput value, another determination is made whether or not one time period has completed. If one time period has completed, a total throughput value and an exponential moving average (EMA) throughput value of the communications channel is retrieved, a new EMA throughput value is generated based on the total throughput value and the EMA throughput value, and adjusting the total throughput value based on whether or not the new throughput value is greater than a predetermined maximum throughput value.

摘要： The provision of verification for data storage cartridges having data storage tape media employs determining the volume identity of a data storage cartridge; and providing an internal label at each block of data to be written to the data storage tape media of the data storage cartridge, the internal label at least comprising the volume identity. Verification of a label comprises reading an external label of the cartridge, the external label at least comprising a volume identity of the cartridge; determining whether the tape media comprises valid data arranged in blocks; positioning the tape media at one of the data blocks and attempting to read an internal label from the data block; and if so, determining whether the volume identity of the external label matches the volume identity of the internal label, and, if so, determining that the matching volume identity is the volume identity of the cartridge.

摘要： Provided are a method, system, and article of manufacture for maintaining message versions at nodes in a network. The nodes in the network maintain version information of nodes in the network. The version information for the nodes indicates a message version number of messages supported at the node. The nodes supporting one message version number can receive messages having that message version number. The nodes use the version information to determine whether there is at least one common message version number among the nodes The nodes supporting the at least one common message version number negotiate to join a quorum of the nodes having the at least one common message version number.

摘要： A computer processor subsystem, e.g. called a “target”, in response to receiving an update to vital product data of the system from a source computer processor subsystem, examines the update to detect the vital product data of the target computer processor subsystem stored by the source computer processor subsystem; and, in response to the detected vital product data being incorrect, the target computer processor subsystem forwards its correct vital product data to the source computer processor subsystem having the incorrect vital product data. A computer processor subsystem is the authoritative reference for its vital product data.

摘要： An apparatus, system, and method are disclosed for recovering a message from a failed node. A message module communicates a message to a request queue and a copy queue. A transfer module transfers the message from the request queue to a first target node in response to the message residing in the request queue. A detection module detects a failure of the first target node. A recovery module copies the message from the copy queue to the request queue in response to the failure of the first target node and the message residing in the copy queue. The transfer module further transfers the message from the request queue to a second target node in response to the message residing in the request queue.
