    Abstract: A computer system, such as a data storage system, implements techniques for segregating and controlling access to data stored in multiple regions. In some embodiments, redundancy coded shards generated from the data and stored in durable storage of a data storage system is allocated across multiple regions, but in a fashion that prevents actors with access to regions outside that of a “home” region from recovering a sufficient number of unique shards to regenerate the data represented thereby. In some embodiments, encryption is used to segregate the data by encrypting the generated shards, then storing the cryptographic information on or otherwise controlling access on hosts or other devices of only the home region.

    Abstract: A configuration request comprising a security option selected for a particular data stream is received. Nodes of a plurality of functional categories, such as a data ingestion category and a data retrieval category are to be configured for the stream. The security option indicates a security profile of a resource to be used for nodes of at least one functional category. In accordance with the configuration request, a node of a first functional category is configured at a resource with a first security profile, and configuration of a node of a second functional category is initiated at a different resource with a different security profile.

    Abstract: Methods and apparatus for vibration cancellation are disclosed. Vibration data from one or more vibration detectors associated with a storage device is collected. The vibration data represents vibrations experienced by the storage device. In response to the vibration data from the one or more vibration detectors, one or more movements for respective ones of one or more counter-vibration actuators to at least partially cancel of the vibrations experienced by the storage device is calculated. The one or more counter-vibration actuators perform the one or more movements.
