In their own words
Ceph
Ceph is free, open-source distributed storage software for object, block, and file storage in one system. Organizations run clusters on commodity hardware that they choose and manage. Its RGW object storage supports the S3 API and Swift-compatible applications. RBD provides thin-provisioned disk images, snapshots, writable clones, and asynchronous mirroring to remote Ceph clusters. CephFS is a POSIX-compliant distributed filesystem with snapshots, quotas, and multi-cluster mirroring. The system can replicate data across devices, racks, and geographic locations, then redistribute it following hardware or connectivity failures. For Kubernetes, the project recommends Rook to run Ceph or connect an existing cluster; its CSI driver can provision block and file volumes. Installation choices include packages, container images, source clones, and tarballs. The cephadm tool requires Python 3, systemd, and Podman or Docker. Production guidance calls for at least three monitors, two managers, three OSDs, and 10 Gb/s networking between hosts. The project publishes a stable release annually and supports each series for approximately 24 months.
TrueNAS
TrueNAS Community Edition is free storage software that provides file, block, and object storage through one interface. It uses ZFS capabilities including snapshots, replication, RAID-Z, and self-healing checksums. Listed services include SMB, NFS, iSCSI, S3 API compatibility, apps, Docker containers, and virtual machines. Administrators can manage it through a web UI or CLI and use SNMP, syslog, reporting, and the TrueNAS API. Security options include self-encrypted drives, dataset encryption, encrypted replication, WireGuard, OpenVPN, ACLs, and IP filtering. The maker lists integrations or certifications involving Kubernetes CSI, Proxmox, VMware, Veeam, Red Hat OpenShift, and others. The Community Edition is a free software download for x86 hardware, with support through forums, documentation, release notes, and bug ticketing. Professional support is described for Enterprise customers. TrueNAS publishes security advisories and recommends configuring systems according to its security best practices. Moving from TrueNAS CORE to Community Edition is a one-way upgrade.
