Abstract
Data replication systems and methods are disclosed. In one embodiment, the method comprises at a system controller of a disk device, receiving data at a system controller of a removable cartridge storage device, transferring the data to a first portable data cartridge and transferring the data to a second portable data cartridge. The first and second portable data cartridges are electrically coupled with the system controller and removably coupled with the removable cartridge storage device.
Claims23
A method comprising:
- receiving data at a system controller of a removable cartridge storage device;
- initiating first and second cartridge interface processes, wherein:
- the first cartridge interface process is communicatively coupled to a first portable data cartridge,
- the second cartridge interface process is communicatively coupled to a second portable data cartridge, and
- each of the first and second portable data cartridges is removably coupled with the removable cartridge storage device;
- transferring, with the first cartridge interface process, the data to the first portable data cartridge;
- switching from transferring the data to the first portable data cartridge to transferring, with the second cartridge interface process, the data to the second portable data cartridge;
- and
- receiving the data at the first portable data cartridge from the first cartridge interface process and processing the data for storage at the first portable data cartridge;
- receiving the data at the second portable data cartridge from the second cartridge interface process and processing the data for storage at the second portable data cartridge wherein:
- the system controller switches from transferring the data to the first portable data cartridge to transferring the data to the second portable data cartridge prior to the data being completely processed at the first portable data cartridge, and
- the first portable data cartridge is processing the received data simultaneously while the second portable data cartridge is processing the received data;
- receiving, at the removable cartridge storage device, commands and the data;
- and
- processing, with the system controller, the commands;
- wherein:
- the removable cartridge storage device comprises a housing at least partially containing at least the system controller, and first and second cartridge holders,
- the housing is configured to receive the first and second portable data cartridges;
- and
- upon receiving the data at the first and second portable data cartridges, each of the first and second portable data cartridges can be removed independently from the removable cartridge storage device and later used independently to retrieve the data.

A data replication system comprising:
- a first cartridge holder and a second cartridge holder, the first and second cartridge holders each including an electrical connector configured to removably couple with a mating electrical connector of a portable data cartridge having an electronic interface;
- a system controller configured to receive data from a host computer system and, in response to receiving the data, to initiate a first cartridge interface process to transfer the data to a first portable data cartridge removably coupled with the first cartridge holder and to initiate a second cartridge interface process to transfer the data to a second portable data cartridge removably coupled with the second cartridge holder;
- a multiport multiplexer, coupled between the system controller and the first and second cartridge holders, to electronically alternatively couple the first cartridge interface process from transferring the data to the first cartridge holder to the second cartridge interface process transferring the data to the second cartridge holder, wherein:
- the first data cartridge processes the data for storage at the first portable data cartridge,
- the second data cartridge processes the data for storage at the second portable data cartridge
- the multiport multiplexer switches from coupling the first cartridge interface process from transferring the data to coupling the second cartridge interface process transferring the data prior to the data being completely processed by the first portable data cartridge, and
- the first portable data cartridge is processing the data simultaneously while the second portable data cartridge is processing the data;
- and
- a housing at least partially containing at least the system controller, the multiport multipexer and the first and second cartridge holders,
- wherein, upon transferring the data to the first and second portable data cartridges, each of the first and second portable data cartridges can be removed independently from the first and second cartridge holders and later used independently to retrieve the data.
