Abstract

Computer implemented systems and methods for migrating datacenter data include providing a quantity of carriers having a data storage capacity, receiving, by the quantity of carriers, a quantity of data stored in a first data storage system having a first location and including erasure coded data blocks. The quantity of carriers migrates to a second data storage system having a second location; and transmits the quantity of data to the second data storage system.

Claims

1. A method for migrating data, the method comprising:

providing a quantity of carriers having a data storage capacity;

receiving, by the quantity of carriers, a quantity of data stored in a first data storage system having a first location, wherein the quantity of data comprises erasure coded data blocks;

migrating the quantity of carriers to a second data storage system having a second location; and

transmitting, by the quantity of carriers, the erasure coded data blocks to the second data storage system.

2. The method according to claim 1 wherein providing a quantity of carriers having a data storage capacity comprises providing a quantity of carriers having a data storage capacity greater than the quantity of data stored in the first data storage system.

3. The method according to claim 1 wherein receiving the erasure coded data blocks by the quantity of carriers comprises receiving the erasure coded data blocks using a data transfer protocol selected from the group consisting of:

iSCSI (Internet Small Computer System Interface) over a UDP (User Datagram Protocol) network, and iFCP (Internet File Communications Protocol) over a UDP network.

4. The method according to claim 1 wherein migrating the quantity of carriers to a second data storage system includes flying a set of carriers from the first location to the second location.

5. The method according to claim 4 further comprising receiving destination GPS (Global Positioning System) coordinates for the second location by the set of carriers.

6. The method according to claim 1 wherein receiving, by the quantity of carriers, a quantity of data stored in a first data storage system having a first location, wherein the quantity of data comprises erasure coded data blocks includes receiving, by the quantity of carriers, a quantity of data stored in a first data storage system having a first location, wherein the quantity of data comprises erasure coded data blocks having an IP (Internet Protocol) address assigned to each erasure coded data block.

7. The method according to claim 1 further comprising reconstructing a portion of the erasure coded data blocks as the quantity of carriers are migrating from the first data storage system to the second data storage system.

8. A computer program product for migrating data, the computer program product comprising one or more computer readable storage devices and program instructions stored on the one or more computer readable storage devices, the program instructions comprising:

programmed instructions for providing a quantity of carriers having a data storage capacity;

programmed instructions for receiving a quantity of data stored in a first data storage system having a first location, wherein the quantity of data comprises erasure coded data blocks;

programmed instructions for migrating the quantity of carriers to a second data storage system having a second location; and

programmed instructions for transmitting the erasure coded data blocks to the second data storage system.

9. The computer program product according to claim 8 wherein the programmed instructions for providing a quantity of carriers having a data storage capacity comprise instructions for providing a quantity of carriers having a data storage capacity greater than the quantity of data stored in the first data storage system.

10. The computer program product according to claim 8 wherein the programmed instructions for receiving the erasure coded data blocks comprise instructions for receiving the erasure coded data blocks using a data transfer protocol selected from the group consisting of:

iSCSI over a UDP network, and iFCP over a UDP network.

11. The computer program product according to claim 8 wherein the programmed instructions for migrating the quantity of carriers to a second data storage system include instructions for receiving destination GPS coordinates by a set of carrier UAVs for the second location.

12. The computer program product according to claim 8 wherein the program instructions for receiving a quantity of data stored in a first data storage system having a first location, wherein the quantity of data comprises erasure coded data blocks include instructions for receiving a quantity of data stored in a first data storage system having a first location, wherein the quantity of data comprises erasure coded data blocks having an IP address assigned to each erasure coded data block.

13. The computer program product according to claim 8 further comprising programmed instructions for reconstructing a portion of the erasure coded data blocks as the quantity of carriers are migrating to the second data storage system.

14. The computer program product according to claim 8 further comprising programmed instructions for performing a checksum check of data blocks received by the second data storage system.

15. A computer system for migrating data, the computer system comprising:

one or more computer processors;

one or more computer readable storage devices;

a first data storage system;

a second data storage system; and

program instructions stored on the one or more computer readable storage devices for execution by at least one of the one or more computer processors, the program instructions comprising;

programmed instructions for providing a quantity of carriers having a data storage capacity;

programmed instructions for receiving a quantity of data stored in a first data storage system having a first location, wherein the quantity of data comprises erasure coded data blocks;

programmed instructions for migrating the quantity of carriers to a second data storage system having a second location; and

programmed instructions for transmitting the erasure coded data blocks to the second data storage system.

16. The computer system according to claim 15 wherein the programmed instructions for providing a quantity of carriers having a data storage capacity comprise instructions for providing a quantity of carriers having a data storage capacity greater than the quantity of data stored in the first data storage system.

17. The computer system according to claim 15 wherein the programmed instructions for receiving the erasure coded data blocks comprise instructions for receiving the erasure coded data blocks using a data transfer protocol selected from the group consisting of:

iSCSI over a UDP network, and iFCP over a UDP network.

18. The computer system according to claim 15 wherein the programmed instructions for migrating the quantity of carriers to a second data storage system include instructions for receiving destination GPS coordinates by a set of carrier UAVs for the second location.

19. The computer system according to claim 15 wherein the program instructions for receiving a quantity of data stored in a first data storage system having a first location, wherein the quantity of data comprises erasure coded data blocks include instructions for receiving a quantity of data stored in a first data storage system having a first location, wherein the quantity of data comprises erasure coded data blocks having an IP address assigned to each erasure coded data block.

20. The computer system according to claim 15 further comprising programmed instructions for reconstructing a portion of the erasure coded data blocks as the quantity of carriers are migrating to the second data storage system.
