System and method for distributed partitioned library mapping
View Patent ↗A system and method of media library access that utilizes distributed mapping of media library partitions. A first controller can be connected to a data transport element of a media library and a second controller can be connected to a media changer of the media library. The first controller can maintain a media library partition representing a portion of the media library, receive a command from a host application based on the media library partition and forward the command to the second controller. The first controller can further translate logical addresses referenced in the command to physical addresses before forwarding the command to the second controller. The second controller can receive the command from the first controller and forward the command to the media changer. The second controller can also prioritize the command using a FIFO or other prioritization scheme.
1. A system of distributed partitioned library mapping, comprising:
a first controller connected to a host via first data transport medium operating according to a first protocol and a data transport element of a media library via a second data transport medium operating according to a second protocol, wherein the first controller:
maintains a media library partition representing a portion of the media library;
receives a command from a host application based on the media library partition;
maps a logical address referenced in the command to a corresponding physical address based on the media library partition;
forwards the command with the corresponding physical address; and
a second controller connected to a media changer of the media library and the first controller, wherein the second controller:
receives the command from the first controller; and
forwards the command to the media changer.
2. The system of claim 1 , wherein the first protocol comprises an iSCSI protocol and the second protocol comprises an iSCSI protocol.
3. The system of claim 1 , wherein the first protocol comprises a Fibre Channel protocol and the second protocol comprises an iSCSI protocol.
4. The system of claim 1 , wherein the first protocol comprises an iSCSI protocol and the second protocol comprises a Fibre Channel protocol.
5. The system of claim 1 , wherein the first protocol comprises an iSCSI protocol and the second protocol comprises a SCSI protocol.
6. The system of claim 1 , wherein the first protocol comprises a SCSI protocol and the second protocol comprises an iSCSI protocol.
7. The system of claim 1 , wherein the first protocol comprises an iSCSI protocol and the second protocol comprises an ATA protocol.
8. The system of claim 1 , wherein the first protocol comprises an ATA protocol and the second protocol comprises an iSCSI protocol.
9. The system of claim 1 , wherein the first protocol comprises an iSCSI protocol and the second protocol comprises a SATA protocol.
10. The system of claim 1 , wherein the first protocol comprises a Serial ATA protocol and the second protocol comprises an iSCSI protocol.
11. The system of claim 1 , wherein the first protocol comprises a Fibre Channel protocol and the second protocol comprises a Serial Attached SCSI protocol.
12. The system of claim 1 , wherein the first protocol comprises a Serial Attached SCSI protocol and the second protocol comprises a Fibre Channel protocol.
13. The system of claim 1 , wherein the first protocol comprises an iSCSI protocol and the second protocol comprises a Serial Attached SCSI protocol.
14. The system of claim 1 , wherein the first protocol comprises a Serial Attached SCSI protocol and the second protocol comprises an iSCSI protocol.
15. The system of claim 1 , wherein the first protocol comprises a Fibre Channel protocol and the second protocol comprises an ATA protocol.
16. The system of claim 1 , wherein the first protocol comprises an ATA protocol and the second protocol comprises a Fibre Channel protocol.
17. The system of claim 1 , wherein the first protocol comprises a Fibre Channel protocol and the second protocol comprises a SATA protocol.
18. The system of claim 1 , wherein the first protocol comprises a SATA protocol and the second protocol comprises a Fibre Channel protocol.
19. The system of claim 1 , wherein the first protocol comprises a Fibre Channel protocol and the second protocol comprises a Serial SCSI Architecture protocol.
20. The system of claim 1 , wherein the first protocol comprises a Serial SCSI Architecture protocol and the second protocol comprises a Fibre Channel protocol.
