Abstract:
A plurality of storage nodes in a single chassis is provided. The plurality of storage nodes includes a first plurality of storage nodes configured to communicate together as a first storage cluster and a second plurality of storage nodes configured to communicate together as a second storage cluster. Each of the first and second pluralities of storage nodes has nonvolatile solid-state memory for user data storage and each of the first and second pluralities of storage nodes is configured to distribute user data and metadata associated with the user data throughout a respective plurality of storage nodes such that a respective storage cluster maintains ability to read the user data, using erasure coding, despite a loss of one or more of the respective plurality of storage nodes.
Abstract:
A plurality of storage nodes cooperating as a storage cluster is provided. Each of the plurality of storage nodes has storage memory. Each storage node of the plurality of storage nodes is configurable to direct erasure coded striping of data of one of an Mode or data segment across the plurality of storage nodes of the storage cluster, with at least one storage node of the plurality of storage nodes having a differing amount of storage capacity of the storage memory from an amount of storage capacity of another storage node in the plurality of storage nodes. A method of storing data in a storage cluster is also provided.
Abstract:
A storage grid is provided. The storage grid includes a first cluster, a second cluster, and a third cluster. Each of the first cluster, the second cluster and the third cluster is configured to store an amount of data ranging from a portion of a copy of the data to a full copy of the data. The first cluster has a full copy of data written to the first cluster and at least a partial copy of data written to the second and third cluster. The second cluster has a full copy of data written to the second cluster, and at least a partial copy of the data written to the first and third cluster. The third cluster has a full copy of data written to the third cluster and at least a partial copy of the data written to the first and second cluster. A method of storing data is also provided.
Abstract:
A plurality of storage nodes in a single chassis is provided. The plurality of storage nodes in the single chassis is configured to communicate together as a storage cluster. Each of the plurality of storage nodes includes nonvolatile solid-state memory for user data storage. The plurality of storage nodes is configured to distribute the user data and metadata associated with the user data throughout the plurality of storage nodes such that the plurality of storage nodes maintain the ability to read the user data, using erasure coding, despite a loss of two of the plurality of storage nodes. The chassis includes power distribution, a high speed communication bus and the ability to install one or more storage nodes which may use the power distribution and communication bus. A method for accessing user data in a plurality of storage nodes having nonvolatile solid-state memory is also provided.
