Filed:

Mar 22, 2001

Appl. No.:

09/814453

Inventors:

John M. Amaral - Roxborough MA, US
David R. Davis - Leominster MA, US
Edmund P. Chin - Hudson MA, US

Assignee:

Artel Video Systems, Inc. - Marlborough MA

International Classification:

H04J 3/06

US Classification:

370389, 370517

Abstract:

Transmitting data packets received from a non-constant delay medium includes storing the data packets in a buffer, determining a play-out schedule for the data packets based on timing information in the data packets, and transmitting the data packets from the buffer in accordance with the play-out schedule. Two of the data packets may contain time-stamps and the play-out schedule may be determined based on a difference between the time-stamps.

Abstract:

Techniques for performing de-duplication for data blocks in a computer storage environment. At least one chunking/hashing unit receives input data from a source and processes it to output data blocks and content addresses for them. In one aspect, the chunking/hashing unit outputs all blocks without checking to see whether any is a duplicate of a block previously stored on the storage environment. In another aspect, each data block is processed by one of a plurality of distributed object addressable storage (OAS) devices that each is selected to process data blocks having content addresses with a particular range. The OAS devices determine whether each received data block is a duplicate of another previously stored on the computer storage environment, and when it is not, stores the data block.

International Classification:

G06F 9/455
G06F 9/50

Abstract:

Cluster groups define a relationship between clusters in an HCI system. New cluster groups may be created, and a cluster may be added or removed from an existing cluster group. A method and system are disclosed to support a dynamically scaled hyperconverged system with non-overlapping and overlapping cluster groups. A dynamically scalable hyperconverged system may allow for piece-wise upgrades while supporting inter-operable and non-interoperable components having a secure intercommunication capability. A system is disclosed for scaling a single managed hyperconverged infrastructure (HCI) where all components are allowed to run a compatible communication protocol (e.g., interoperable communication protocol) but are not required to operate an interoperable software version. Further, methods are disclosed to a) illustrate consolidation of backups for a cluster of HCI nodes running interoperable and non-interoperable data exchange protocols; and b) dynamically organize groups of clusters to enforce interoperability requirements and simplify network configuration among these clusters.

International Classification:

G06F 8/65
G06F 9/455

Abstract:

The disclosure provides for systems and methods for performing upgrades in virtual environments. Some implementations are directed to using an upgrade service to provide pre-upgrade component detection and validation on host(s). A software package may be submitted to an existing software upgrade procedure of a host. The software package may include an upgrade executable that, when launched, provides a new software service, including initializing one or more new public-facing APIs to provide pre-upgrade host component detection and validation. Some implementations are directed to coordinating the upgrade of a first host using an upgrade service launched on another networked machine or second host. While running an upgrade service, the first host may make a request to the second host to coordinate the upgrade of components of the first host while the first host or a VM of the first host running the upgrade service is shut down.
