Qumulo is a NAS system offered as software only or as a complete system by Qumulo with standard servers. Qumulo software is also offered by HPE on Apollo servers, as well as through a solution from Fujitsu. The Qumulo software uses clusters of nodes that may be deployed on-premises or as a software instance in public clouds. The clusters continuously replicate data between them for data protection. Performance and capacity scale with the addition of nodes to a cluster.
The Qumulo software executes on the distributed nodes in a cluster and present a single, unified file system for the cluster. Different than high performance scale-out parallel file systems, Qumulo uses standard protocols for access rather than a custom client and client-side kernel drivers and runs in user space.
A notable feature of the Qumulo software is the real-time analytics that provides information on performance hot-spots and issues that can be addressed to optimize the system. Qumulo also offers cloud-based analytics for proactive problem prevention and determination.
The backend storage for Qumulo is called Scalable Block Storage, which is a database of block placement for data. Both SSDs and HDDs are supported with integrated tiering of hot and cold data using the block placement controls. The organization of the data is a tree structure with the database containing information for access to the data. Metadata is separate from data but managed through the same database tree-structured access.
Features included with Qumulo include replication to other clusters, snapshots, quotas, and the aforementioned analytics. Qumulo also provides the ability to migrate file data from any Qumulo system, whether on premises or in the cloud, to AWS S3 where it will be transformed and stored as object data with Qumulo’s Shift functionality.
