  • DATA DEDUPLICATION SYSTEM
    Publication number: 20210117393
    Abstract: A data deduplication system includes a data deduplication subsystem coupled to each of a host system and a storage system. The data deduplication system receives data from the host system, generates a data deduplication identifier for the data, and determines whether the data deduplication identifier for the data is stored in a data deduplication database. In response to determining that the data deduplication identifier is not stored in the data deduplication database, the data deduplication system stores the data deduplication identifier for the data in the data deduplication database in association with a data counter for the data, and transmits the data to the storage system for storage. In response to determining that the data deduplication identifier is stored in the data deduplication database, the data deduplication system increments a data counter that is associated with the data deduplication identifier in the data deduplication database, and discards the data.

  • Method and system for non-disruptive host repurposing
    Patent number: 10628146
    Abstract: A method and system for non-disruptive host repurposing. Specifically, the method and system disclosed herein entail the re-optimization of datacenter hosts (e.g., servers) for any infrastructure and/or workload deployment. Different infrastructure and/or workload deployments may require the tuning of various memory parameters (or attributes) in the basic input-output system (BIOS) configuration. Presently, the repurposing of any given host demands the full reset of the system configuration—i.e., a disruptive process—prior to implementing the necessary BIOS configuration changes. In contrast, the method and system disclosed herein facilitate the repurposing of a host through the installation and/or uninstallation of configuration overlays—a modular approach to interchanging infrastructure and/or workload deployments—without the disruption of full system resets.
