The Hammerspace Global Data Environment (GDE) is a software-defined storage approach to a global file system. Hammerspace GDE can be deployed as a hybrid cloud, multi-site NAS or multiple cloud setup, enabling users to interact with and share metadata stored in any location. GDE provides orchestration through a set of data services.
Like other Global File Systems targeted at a distributed workforce, Hammerspace’s goal is to provide access to files as if they were local regardless of where they or the data sets reside. Hammerspace does this by managing metadata instead of storing a golden copy in the cloud and caching frequently accessed data locally, as several of its competitors do.
Hammerspace is less cloud-centric than competitors such as Nasuni, CTERA and Panzura. Hammerspace’s focus is more on customers with multiple data centers and a smaller cloud component than companies looking to move the bulk of their file storage to the cloud. They all share the goal of enabling a global workforce, including those with a large work-at-home force. Hammerspace does this by making network shares visible and accessible to all workers as if they were at a physical data center.
Hammerspace does share common characteristics with other global file system vendors, including a global namespace, file synchronization and built-in data protection features such as snapshots, file versioning and disaster recovery.
The GDE installs as an ISO on bare metal servers from Dell, HPE, SuperMicro and others or virtual machines, including VMware ESX, Microsoft Hyper-V, KVM and Nutanix AHV. Hammerspace software can also be installed on AWS EC2, Google Cloud Platform, or Microsoft Azure public clouds, and is sold through the public cloud marketplaces. It supports NFS, SMB and pNFS file protocols, and Kubernetes through a CSI driver. It works with NAS products including Dell EMC PowerScale (Isilon), NetApp, Qumulo, and object storage such as Dell EMC ECS, NetApp StorageGrid, Scality, Cloudian or any S3-capable object storage.
Hammerspace GDE handles data management through automated orchestration that exposes direct access to the same data for users across multiple sites through the parallel global file system. GDE separates the global metadata control plane from the data orchestration layer.
Instead of caching data as some cloud-focused global file systems vendors do, Hammerspace relies on frequent metadata updates (the default is every 5 seconds but users can configure them to take place more or less frequently). The frequent updates keep consistent metadata at all locations, all sharing a global namespace. As changes are made to files in one location, users at other sites see the same file with those changes. Hammerspace has tested its GDE across 100 locations.
