Abstract: A volume for object storage encompasses a single logical block address space and the first range of logical block addresses being within the single logical block address space. A first and second range of logical block addresses are initially allocated within the single logical block address space of the volume for storing respective object metadata and object data. One or both of the first and second ranges of logical block addresses are reallocated to increase storage utilized by one of the object metadata and the object data.

Abstract: A storage command is received from a client computer. The storage command includes a key associated with a content object that is to be written to two or more storage nodes in response to the command. A virtual address space is used to indicate a storage location of the content object. A virtual address of the virtual address space is assigned to the content object. The content object is redundantly stored the two or more storage nodes at respective two or more device addresses of the respective two or more storage nodes. The two or more device addresses are mapped to the virtual address, and the virtual address is returned to the client computer as a hint.

Abstract: A method includes adding new storage capacity to a data storage system, which has a pre-existing storage capacity. The method further includes rebalancing data from the pre-existing storage capacity to the new storage capacity in connection with a non-rebalancing operation performed on the pre-existing storage capacity.

Abstract: Systems and methods are disclosed for data validation for zero copy protocols. In some examples, a server may include hardware, software, or a combination thereof to provide flexibility and data validation for a read request operation of a zero copy protocol. A read request operation can include a validation request frame, a status response frame, or both. In further examples, the validation request frame, the status response frame, or both can be configured by a requesting device to facilitate read data validation. In yet further examples, another device can receive a read request operation with a variably configured validation request frame, status response frame, or both and configure one or more data validation processes based on such.
