摘要： Transferring data elements from a source to a destination includes providing a transmission queue at the source, where data elements in the transmission queue are transferred from the source to the destination, determining an optimal length for the transmission queue, where the optimal queue length is inversely proportional data latency time at the destination, and, if the optimal length is greater than an instantaneous length of the transmission queue, adding data elements to the transmission queue. Adding data elements may include adding a number of elements corresponding to a difference between the optimal length and the instantaneous length of the transmission queue. Determining optimal length may include dividing a constant by the data latency time at the destination. Transferring data elements may also include providing a network between the source and the destination.

摘要： Described are techniques used in dynamically modifying RDF groups. A system call is issued by a host computer system to execute a remote system call on a first data storage system to create, remove, or modify an RDF group between the first data storage system and another data storage system that is remotely connected to the first data storage system in an RDF switched environment. As part of executing the remote system call, data is pushed from the first to the second data storage systems without having an established link between the data storage systems. Each data storage system performs processing to make the necessary modifications in all directors in accordance with the dynamic RDF group. A status indicating success or failure of the remote system call is returned to the host computer system.

摘要： Storing recovery data for a data center includes providing synchronous data from the data center to a local destination, providing chunks of data from the local destination to a first remote destination, different from the first remote destination, and providing chunks of data from the data center to a second remote destination. At least some of the destinations may maintain a plurality of maps, where each of the maps associates synchronous data being provided to the local destination with a specific chunk of data. In response to receiving an indicator in connection with creation of a new chunk of data, the at least some of the destinations that maintain a plurality of maps may point to a new map. There may be two maps or more than two maps.

摘要： Dynamically creating a communication path between first and second storage devices, includes creating a connection to a source volume on the first storage device and indicating that the source volume is not ready to transmit data on the communication path, after successfully creating the connection to the source volume, creating a connection to a destination volume on the second storage device and initially indicating that portions of one of: the destination volume and the source volume do not contain valid copies of data, where the destination volume accepts data from the source volume, and after successfully creating the connections to the source and destination volumes, indicating that the source volume is ready to transmit data on the communication path. Dynamically creating a communication path between first and second storage devices, may also include creating at least one of: the source volume and the destination volume. Creating the connection to the source volume may include modifying a table containing configuration information for the first storage device. Creating the connection to the destination volume may include modifying a table containing configuration information for the second storage device.

摘要： Handling ordered writes to a data storage device includes receiving a first chunk of data into slots of a cache of the data storage device and using a hash table to provide a correlation between cache slots containing data from the first chunk of data and locations of a logical storage device of the data storage device. Handling ordered writes may also include maintaining a circularly linked list of pointers to cache slots containing the first chunk of data. Handling ordered writes may also include receiving a second chunk of data into slots of the cache of the data storage device and receiving a message indicating that all data corresponding to the first chunk of data has been transferred to the data storage device. Handling ordered writes may also include, in response to receiving the message, storing data from the first chunk on to the logical storage device. Handling ordered writes may also include using a hash table to provide a correlation between cache slots containing data from the second chunk of data and locations of a logical storage device of the data storage device.

摘要： A mechanism to support remote mirroring of storage devices by data storage systems in a one-to-many switched environment. Each data storage system includes a disk director that is adapted to control at least one device group that is supported in a mirrored configuration with a corresponding device group controlled by one of the other data storage systems. For each device group and corresponding device group, there are first ports associated with the device group and second ports associated with the corresponding device group. A switch element is adapted to connect one of the first ports to at least one of the second ports so that data may be exchanged between the ports for each device group and corresponding device group. The disk director selects which first port is to be connected to which second port via the switch element in the establishment of a logical link. Thus, each port connected to the switch is capable of achieving multiple connections to multiple destinations for increased connectivity, redundancy and performance (load balance) without additional hardware.
