Multi-tenancy in HPE Ezmeral Data Fabric refers to the ability to securely and cost-effectively share IT resources among multiple data sets, user groups, and applications within a single cluster. This approach allows organizations to maintain strict isolation between different tenants while enabling some level of data sharing when necessary. It is crucial for managing diverse workloads and ensuring that users only access the data they are authorized to use.

Multi-tenancy is essential for data lifecycle management in HPE Ezmeral Data Fabric as it allows different user groups to manage various stages of data transformations. Each group can be responsible for specific data stages, such as raw ingested data or archived data, stored as separate tenants. This ensures that only authorized users can access the data at each stage and allows administrators to set limits on compute and storage usage for each tenant.

HPE Ezmeral Data Fabric employs cryptographically secure authentication and encryption methods to safeguard data. It supports both Kerberos infrastructure for authentication and a native ticket-based system for organizations without Kerberos. Additionally, it offers fine-grained access control through access control expressions (ACEs) that ensure users can only access data they are permitted to, reinforcing security at various levels, including volumes and individual files.
