Gluster vs LizardFS

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.

LizardFS is an on-premises distributed file system that combines storage from several servers into a single namespace. Data is kept in multiple replicas across available servers, and new servers can be added without downtime; chunks move automatically to balance disk use. Erasure coding divides data into parts and parity stripes, with the maker stating that it can save up to 70% of storage capacity depending on configuration. Snapshots copy metadata while sharing data chunks until a file changes. Georeplication can copy data between data centers and lets administrators choose where data is stored. Administrators can set read and write bandwidth limits and apply soft or hard quotas for file counts and total size. Deleted files go to an administrator-visible trash bin for restoration or permanent deletion. Storage is installed on Linux, with Windows and macOS clients for cluster access. LizardFS supports NFS 3.x, NFS 4.0, and pNFS, and the maker describes using it with Elasticsearch and Logstash. Pricing is available on request; support packages include weekday or 24/7 assistance depending on tier.
