Abstract: A method, non-transitory computer readable medium, and device that assists with managing storage in a distributed deduplication system includes receiving an object to be stored from a client computing device. The received object is divided into a plurality of fragments. A plaintext hash value and a ciphertext hash value is determined for each of the plurality of fragments, wherein each of the plurality of fragments is renamed with the corresponding determined ciphertext hash value. Each of the renamed plurality of fragments are stored in a plurality of storage repositories.

Abstract: Some embodiments involve a method of managing power for a first multiple-data-storage-devices enclosure. The method can include: checking out a first token over a network connection from a token pool shared by multiple-data-storage-devices enclosures including the first enclosure, wherein each token of the token pool is available to be checked out by a single device and wherein the enclosures share power drawn from a power supply; after checking out the first token, initiating activation of a data storage device within the first enclosure; monitoring power consumption within the first enclosure; and releasing the first token back to the token pool when the power consumption in the first enclosure substantially reaches a steady-state after the activation of the data storage device is initiated.

Abstract: A write request including payload data is received. The payload data of the write request is stored in a staging area of a storage manager. A transformation pipeline is determined based, at least in part, on an attribute of the write request. The transformation pipeline is queued for execution. Data fragments are generated based, at least in part, on the payload data and the transformation pipeline. The data fragments are transmitted to a plurality of enclosures.

Abstract: Example embodiments provide various techniques for securing communications within a group of entities. In one example method, a request from an entity to join the group is received and a signed, digital certificate associated with the entity is accessed. Here, the signed, digital certificate is signed with a group private key that is associated with a certification authority for the group. The signed, digital certificate is added to a group roster, and this addition is to admit the entity into the group. The group roster with the signed, digital certificate is itself signed with the group private key and distributed to the group, which includes the entity that transmitted the request. Communication to the entity is then encrypted using the signed, digital certificate included in the group roster.

Abstract: A service level objective (SLO) subsystem that includes an SLO engine in a network storage system that allows new degrees of freedom to be added to the SLO subsystem, without requiring any modification of an associated SLO engine or the system's existing SLOs, and without requiring the SLO engine to have any a priori knowledge of the new degrees of freedom. In certain embodiments, the system has a modular design which includes the SLO engine and one or more SLO modules that interface with the SLO engine. Each SLO module corresponds to a different degree of freedom. Each SLO module evaluates SLO compliance and determines what specific action(s) within its corresponding degree of freedom should be taken to comply with an SLO.
