摘要： Example embodiments of the present invention provide for parallel replication of an IO received by a storage array. Such parallelism provide numerous benefits, including enqueuing the command phase of the write command at the storage array and the replication appliance in parallel, providing data still in memory (i.e., slot) and not destaged to disk, and providing data processing in parallel (e.g., validate checksum, validate data is good, validate internal data structures).

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 for migrating data from a source device of a source data storage system to a target device of a target data storage system. The target data storage system is configured to operate in accordance with a spoofing mode and a pass-through mode. A first set of commands from the host are processed for the target device when in the pass-through mode and the spoofing mode with respect to the target device. Data is migrated from the source device to the target device. The target data storage system is configured to operate in an echo mode for the target device and processes a second set of commands from the host when in the echo mode for the target device using information stored in the cache from processing the first set of commands.

摘要： Methods and systems for preserving disk geometry when relabeling a data volume encapsulated in a virtual storage device that presents a different disk geometry than the data volume. An exemplary method includes maintaining information from a label of the data volume in a memory associated with the virtual storage device and intercepting a request for information related to a disk geometry of the encapsulated data volume that is normally answered without reference to the label. The request may be associated with a command to relabel the encapsulated data volume. The method also includes reporting the information from the label of the data volume related to the disk geometry of the data volume if the label is associated with an operating system that considers a geometry of a data volume when partitioning.

摘要： Described are techniques for migrating data from a source device to a target device. A source device descriptor of the source device including source device geometry parameters and a source device partition definition structure is received. Target device geometry parameters are received. The source partition definition structure is translated and a mapped partition definition structure in accordance with the target device geometry parameters is generated. A target device descriptor including the target device geometry parameters and the mapped partition definition structure is generated. The target device descriptor is stored on the target device. Data for one or more partitions of the source device is migrated to the target device.

摘要： On-line storage devices are migrated to new storage devices in a non-disruptive manner. A host executing multipath I/O software is initially coupled to a source storage device via at least one active path. The target storage device is configured with the source device's device identification information. The target storage device is coupled to the host via a passive path so that the target storage device can return its device identification information to the host but cannot respond to I/O read or I/O write requests from the host. All paths between the host and the source storage device are then disconnected. An on-line data migration session between the source storage device and the target storage device is then activated. The path between the target storage device and the host is then re-configured from passive to active so that the target storage device can respond to I/O read and I/O write requests.

摘要： Methods and systems for preserving a disk geometry when relabeling a storage device containing data migrated from a previous data storage device having different disk geometry. Prior to relabeling, the label of the storage device includes information on the disk geometry of the previous data storage device. An exemplary method includes reading the label of the storage device in response to a request for information related to a disk geometry of the storage device, which is normally answered without reference to the label of the storage device, and reporting the information related to the disk geometry from the label if the label is associated with an operating system that considers a geometry of a storage device when partitioning.
