  • Restoration of erasure-coded data via data shuttle in distributed storage system
    Patent number: 9830221
    Abstract: Embodiments use data shuttle devices to restore erasure-coded data in a distributed storage environment. In some embodiments, a first data shuttle is communicatively coupled to a first node of the storage environment. On the data shuttle, first restoration data is generated from a first erasure-coded data portion stored on the first node. The first data shuttle or a second data shuttle is communicatively coupled to a second node of the storage environment. On the data shuttle at the second node, second restoration data is generated from a second erasure-coded data portion stored on the second node. Subsequent to transporting the first or second data shuttle from at least one of the other nodes to a third node, a third erasure-coded data portion is restored at the third node. The third erasure-coded data portion is generated via an erasure-coding process from one or more of the first or second restoration data.
