Abstract: A computer-implemented method for storing blocks of a file in a heterogeneous environment. The method may comprise receiving a command header for an operation associated with a file from a first data node, matching the enhanced metadata with capabilities of a second data node, and generating a block layout map for the file based at least in part on the enhanced metadata and the capabilities of the second data node. The command header may include enhanced metadata associated with a file, and the enhanced metadata may comprise a type of workload that generated the file and a data access pattern.

Abstract: Methods and systems for encrypting data for a multi-tenant filesystem environment are provided. A system for encrypting data for a multitenant filesystem environment includes a file characteristics module that determines file characteristics for a file. The system also includes a user identification module that collects user identification information for one or more file operations, where a file operation in the one or more file operations is performed on a portion of the file. The system further includes a portion information module that gathers portion information about the portion of the file. Additionally, the system includes an encryption module that associates the portion information with a subtenancy encryption key in one or more subtenancy encryption keys based on the user identification information, where the one or more subtenancy encryption keys are associated with the file.
