20140204940 | SCALABLE TRANSPORT METHOD FOR MULTICAST REPLICATION - Embodiments disclosed herein provide advantageous methods and systems that use multicast communications via unreliable datagrams sent on a protected traffic class. These methods and systems provide effectively reliable multicast delivery while avoiding the overhead associated with point-to-point protocols. Rather than an exponential scaling of point-to-point connections (with expensive setup and teardown of the connections), the traffic from one server is bounded by linear scaling of multicast groups. In addition, the multicast rendezvous disclosed herein creates an edge-managed flow control that accounts for the dynamic state of the storage servers in the cluster, without needing centralized control, management or maintenance of state. This traffic shaping avoids the loss of data due to congestion during sustained oversubscription. Other embodiments, aspects and features are also disclosed. | 07-24-2014 |

20140304357 | SCALABLE OBJECT STORAGE USING MULTICAST TRANSPORT - Embodiments disclosed herein provide a scalable multicast transport. The multicast transport protocol provides effectively reliable multicast delivery while avoiding the overhead associated with point-to-point protocols. Additional embodiments disclosed herein relate to a scalable object storage system that uses a multicast transport. The object storage system assigns responsibility for providing storage services for a chunk to a negotiating group of storage servers in the cluster using a shared and distributed hash allocation table. The object storage system dynamically determines a rendezvous group of storage servers in the cluster to store the chunk using the multicast transport. Other embodiments, aspects and features are also disclosed. | 10-09-2014 |
20140304513 | STORAGE DRIVE PROCESSING MULTIPLE COMMANDS FROM MULTIPLE SERVERS - One embodiment of the invention relates to a key/value storage device. The key/value storage device includes a storage medium for storing data, a network interface for receiving commands sent by multiple servers, and a controller. The controller processes a put command from a server to store a binary data object on the storage medium. The put command passes a key associated with the binary data object, and returns a unique digest of the binary data object to the server via the network interface. Another embodiment relates to a storage drive. The storage drive includes a network interface for receiving, and a controller for processing, multiple commands from multiple servers. Other embodiments, aspects and features are also disclosed. | 10-09-2014 |

The controller processes a put command from a server to store a binary data object on the storage medium. The put command passes a key associated with the binary data object, and returns a unique digest of the binary data object to the server via the network interface. Another embodiment relates to a storage drive. The storage drive includes a network interface for receiving, and a controller for processing, multiple commands from multiple servers.

20160057226 | 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. A roll-call request is multicast to every storage server in a negotiating group for the chunk. Roll-call inventory responses are generated and multicast by every storage server in the negotiating group. The roll-call inventory responses are collected by every storage server in the negotiating group from other storage servers in the negotiating group to form a set of roll-call inventory responses. A logical evaluation of the set of roll-call inventory responses may then be performed by every storage server in the negotiating group. Other embodiments, aspects and features are also disclosed. | 02-25-2016 |
