DataCore SANsymphony vs Gluster

DataCore SANsymphony is self-hosted, block-based software-defined storage for SAN and hyperconverged environments. It pools storage from different hardware and centrally manages capacity provisioning and data placement. Performance tools include RAM caching, parallel I/O processing, auto-tiering, and load balancing. Recovery and availability features include synchronous mirroring, asynchronous replication with failover and failback, snapshots, and continuous data protection. It lists NVMe, Fibre Channel, iSCSI, and SAS/SATA protocols; NFS and SMB access is supported through Windows File Server. Administrators can use a console, REST API, PowerShell API, plug-ins, provisioning and orchestration, and real-time or historical charts. Data services include encryption and immutability, and backup-tool integration is supported. Deployment options include storage virtualization, converged, hyperconverged, and hybrid-converged configurations. Four editions address high-performance, midrange, smaller high-availability, and backup or replication needs. Pricing is on request; there is no free plan, though a trial is available. Server installations require Windows Server 2016 through 2025, with a documented minimum of 8 GB RAM and 20 GB local disk space.

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.
