Abstract: In a particular embodiment, a dataset that is synchronously replicated across a plurality of storage systems is stored on a particular storage system. The storage system identifies input/output (I/O) requests directed to the dataset. The one or more I/O requests are initiated by an application hosted on a platform of the first storage system. The storage system services the one or more I/O requests directed to the dataset.

Abstract: A method of using boot-time metadata in a storage system is provided. The method includes writing a fragmentation stride to a solid-state storage device of the storage system, the fragmentation stride defining a granularity on which fragmentation of erase blocks of the solid-state storage device occurs. The method includes allocating portions of erase blocks for at least one process in the storage system, in accordance with the fragmentation stride and writing boot up metadata at offsets that are based on the fragmentation stride, in the solid-state storage device.

Abstract: In a particular embodiment, a virtual namespace identifier is mapped to one or more volumes stored among a pool of storage resources, wherein at least a first storage system and a second storage system are utilized to provide the storage resources. The virtual namespace identifier is migrated among the pool of storage resources to virtualize a data path for the one or more volumes.

Abstract: A system comprises a storage system comprising one or more storage devices and a storage controller operatively coupled to the storage system, the storage controller comprising a processing device, the processing device to receive first raw data from a first tenant of the storage system to a first non-volatile memory express (NVMe) input/output (I/O) queue of the storage system. The processing device further to determine that the first NVMe I/O queue corresponds to a first key, wherein the first key corresponds to the first tenant. The processing device further to encrypt the first raw data using the first key to generate first encrypted data. The processing device further to store the first encrypted data on the storage system.
