    Abstract: Sharing encryption information amongst storage devices in a storage system, including: detecting that one or more source storage devices has been designated for removal from the storage system; and responsive to detecting that the source storage devices have been designated for removal from the storage system: encrypting a device key for each remaining storage device using a master secret to generate an encrypted device key for each remaining storage device; generating, for each write group, a first plurality of shares from the master secret; creating, from each share of the first plurality of shares, a second plurality of shares equal to a minimum number of the remaining storage devices required from each write group for a quorum to boot the storage system; and storing, for each remaining storage device, the encrypted device key and a respective share of the second plurality of shares in the remaining storage devices.

    Abstract: Selecting storage resources based on data characteristics, including: determining, for data that is stored within a storage system that includes multiple types of data storage, a storage type to use for the data, wherein: the data is associated with one more snapshots that are stored in the storage system, and the determination is based on whether the data that is stored in at least one volume in the storage system, wherein one storage type is selected if the data is stored in at least one volume and another storage type is selected if the data is not stored in at least one volume; and storing the data in a storage device associated with the determined storage type.

    Abstract: A first namespace is generated on a particular storage device of the plurality of storage devices for storing configuration data for a storage system. The first namespace is accessible by one or more storage controllers of the storage system. A second namespace is generated on the particular storage device for storing other data at the particular storage device. The configuration data is stored in the first namespace and the other data is stored in the second namespace.
