Gluster vs IBM Storage Scale

Gluster is free, open-source distributed file-system software for Linux and self-hosted deployments. It combines disk storage from multiple servers into one global namespace, with the project describing scale to several petabytes and thousands of clients. Gluster is POSIX compatible and can use on-disk filesystems supporting extended attributes. Listed capabilities include replication, quotas, geo-replication, snapshots, bitrot detection, and erasure coding. Access options include native GlusterFS, NFS, SMB/CIFS, iSCSI, and a Swift REST API. The project describes workloads such as media streaming, data analysis, and other data- and bandwidth-intensive tasks. Capacity, performance, and availability can scale across on-premise, public-cloud, and hybrid environments, using common off-the-shelf hardware. Installation resources include source downloads and Ubuntu PPAs, while documentation covers AWS deployment, SSL, and access-control lists. The project points users to consultancies for additional support and notes that Red Hat does not support community versions.
