Data storage system providing efficient and secure data migration with tape drive technology

摘要

A data storage system that includes a data migration assembly implemented using tape drive technology. The migration assembly includes tape drive modules or cards stacked within a tape drive chassis, which is adapted for insertion into a tape drive slot of a library or rack enclosure. The data storage system includes a server running a host application to manage data migration processes by transmitting control commands and/or parameters to the tape drive module. The tape drive module, in response, performs the data migration including data extraction from the source device and data loading onto the destination device. The data path passes between the source and destination devices through the tape drive cards but does not include the server running the host application so that data security is provided by the tape drive module along the entire data path rather than data being at risk in a server.

主权项

1. A data migration assembly, comprising:
a chassis configured for insertion into a tape drive slot of a tape library or a rack enclosure; and a first tape drive card supported within an interior space of the chassis, the first tape drive card includes: a processor; and a copy manager run by the processor that is adapted to communicate with a host application, running on a server communicatively linked to the first tape drive card, during a data migration to receive data migration control parameters and, in response, to copy a set of data from one or more source data storage devices to one or more destination data storage devices, wherein the first tape drive card further comprises one or more memory devices providing random access memory (RAM) and wherein the copy manager partitions the RAM into a number of partitions for use in performing a like number of migration sessions, whereby each of the migration sessions has a dedicated portion of the RAM.
