Method and system for maintaining and searching index records

One difficult problem is that a straightforward renaming of a directory containing a very large number of subdirectories and files requires locking and then updating, in parallel, the names of vast numbers of directory records. Another problem is that renaming a directory with a very large number of subdirectories and files may cause a mass migration of the metadata for the renamed objects due to their object names being changed. ...

Multicast collaborative erasure encoding and distributed parity protection

The present disclosure provides methods and systems for multicast collaborative erasure encoding and methods and systems for distributed parity protection. One embodiment relates to a method of multicast collaborative erasure encoding of a chunk stored in a distributed object storage cluster. ... Nexenta Systems Inc

Distributed data storage system using a common manifest for storing and accessing versions of an object

The present disclosure provides a system and method to perform access control authentication using a cryptographic hash of the encoding of access control rules. The compact cryptographic hash identifier of the access control rules is suitable for inclusion in a name indexing entry, whereas inclusion of the full encoding would result in a large name indexing entry, resulting in disadvantageously large storage requirements and bandwidth usage. ...

Multicast raid: distributed parity protection

The present invention introduces a specific form of parity protection chunk (ppc) that allows for distributed creation of coordinated ppcs that can reliably provide protection against the concurrent loss of two or more storage servers of devices. Coordinated ppcs can protect against the concurrent loss of multiple lost chunks by ensuring that the ppcss protecting any specific chunk have at most a single overlapping failure domain. ... Nexenta Systems Inc

Parity protection for data chunks in an object storage system

The present invention relates to a method and system for providing parity protection in an object storage system. The present invention allows for tracking the storage requirements for chunks in a distributed storage cluster when transitioning from replica-based protection to parity or erasure coding-based protection and when transitioning from parity or erasure coding-based protection to replica-based protection.. ... Nexenta Systems Inc

Negotiating proxy server for distributed storage and compute clusters

The present invention defines a new type of negotiating proxy server which optimizes a multi-node collaboration of distributed servers, where the goal of the negotiation is to synchronize rendezvous interactions between the initiator and subsets of servers in multicast groups. For example, in distributed storage clusters servers commit to receiving and then storing a chunk of data in parallel at a specified time, while in compute clusters servers perform one portion of a calculation in parallel. ...

Object storage system with a distributed namespace and snapshot and cloning features

The present invention relates to a distributed object storage system that supports snapshots and clones without requiring any form of distributed locking—or any form of centralized processing. A clone tree can be modified in isolation and the modifications then either discarded or merged into the main tree of the distributed object storage system.. ... Nexenta Systems Inc
