Methods and apparatus to dynamically assign and relocate object fragments in distributed storage systems are disclosed. In some examples, an apparatus to compile fragments of an object includes a fragment compiler to: compile an object from fragments stored in storage nodes, respective ones of the fragments corresponding to (a) a node index of storage identifiers representative of the storage nodes and (b) a fragment index of fragment identifiers associated with the respective ones of the fragments of the object, respective ones of the fragment identifiers being representative of a sequential order of the fragments of the object, the respective ones of the fragment identifiers to be associated with the respective ones of the storage identifiers to enable verification of storage locations of the respective ones of the fragments of the object relative to respective storage nodes; request a first one of the fragments from a first one of the respective storage nodes; determine if a first fragment index assigned to the first one of the fragments matches a first node index assigned to the first one of the fragments; when the first fragment index matches the first node index, compile the first one of the fragments into the object based on the first node index; and when the first fragment index does not match the first node index, compile the first one of the fragments into the object based on the first fragment index.

Methods and apparatus to assign indices and relocate object fragments in distributed storage systems

A technique is applied to eventually converge on a single data storage strategy for any set of object data which had an inconsistent data storage strategy applied during storage while there was a network partition. This state could occur in instances of a highly available distributed object storage system which can store objects according to multiple data storage strategies. Upon the healing of a network partition, the technique discovers if multiple data storage strategies were applied to the object data stored during a network partition, deterministically identifies which data storage strategy represents the correct strategy, for example based on the log of state transitions requested by the client according to the API contract, and ensures that this strategy is consistently applied to all object data in the collection.

Reconciler for a distributed storage system

Methods and apparatus to dynamically assign and relocate object fragments in distributed storage systems are disclosed. In some examples, the methods and apparatus encode an object with error correction coding to separate the object into fragments, create a first index indicative of storage nodes where the fragments of the object are to be stored, encode a second index into identifiers of the fragments of the object, the second index based on the first index, and store the fragments of the object and the corresponding second index encoded identifiers in the storage nodes based on the first index.

Methods and systems are disclosed for secure bi-directional message routing between services running on a different nodes in a computer cluster. According to some embodiments, a multi-tenant computer cluster is accessed online via a controller. The controller, acting as central management system, may establish secure independent connections with each of the many nodes. Messages from the controller to any given node, and vice versa, are wrapped in a routing envelope and transferred over an independent and secure virtual private network tunnel. This allows the plurality of nodes to be centrally managed and utilized as a cluster while not being allowed to communicate with each other.

Method and apparatus for bidirectional message routing between services running on different network nodes

A technique is introduced that enables a server to establish trust of and a secure channel of communication with an unverified client computer, which can be on a different insecure network. To establish trust, the server needs to ensure that the client computer is legitimate, and the client computer similarly needs to ensure that the server is legitimate. With mutual trust established, a secure channel of communication is established between the server and the client computer. With mutual trust and a secure channel of communication established, the client computer can safely communicate with the server, for example, to download software that enables the client computer to join a central management system at the server.
