The open-source stack, piece by piece
45Drives’ storage servers are built entirely on established, independently-maintained open-source projects. This section covers each piece on its own: what it is, why it’s used, and where to see the real code.
45Flow
45Drives' own open-source file collaboration and video review platform, built for media-heavy workflows.
autotier
45Drives doesn't just build on open source — autotier is their own open-source contribution back to the community.
Ceph
Why 45Drives builds scale-out storage on Ceph, the open-source distributed storage system.
DRBD & LINSTOR
Why 45Drives partners with LINBIT on DRBD and LINSTOR for synchronous, block-level high availability — a smaller-scale complement to Ceph.
Honeypot-Based Ransomware Detection
An open-source honeypot approach to detecting ransomware in Samba shares that 45Drives keeps a reference copy of — the same core idea productized in SnapShield.
Houston UI
45Drives' Houston UI is a web dashboard built on the open-source Cockpit project — the easiest way to see the open-source storage stack in action.
iSCSI
45Drives' iSCSI support runs on SCST, the open-source Linux SCSI target subsystem — including a clustered, Ceph-backed HA mode.
Linux Package Repository
45Drives publishes real Debian and RHEL-family package repositories — here's exactly what's supported, checked directly against the live repo.
Monitoring (Prometheus, Grafana, Alertmanager)
Why 45Drives builds storage monitoring on Prometheus, Grafana, and Alertmanager instead of a proprietary dashboard.
NFS
Why 45Drives serves Linux/Unix file sharing through NFS, the original network filesystem protocol.
Proxmox VE
Why 45Drives' Proxinator virtualization line is built on Proxmox VE, the open-source hypervisor platform.
S3 / RADOS Gateway
Why 45Drives offers S3-compatible object storage through Ceph's RADOS Gateway, without a cloud subscription.
Samba
Why 45Drives serves Windows/macOS file sharing through Samba, the open-source implementation of the SMB protocol.
STIG Hardening
45Drives publishes real STIG security hardening overlays for Rocky Linux — relevant to government and defense customers under CMMC.
Storage Encryption & Key Management
45Drives manages LUKS disk encryption keys via OpenBao, the open-source Vault fork — with an optional path to a commercial hardware security module for higher assurance needs.
WireGuard (Wireshield)
45Drives builds encrypted networking on WireGuard, the modern open-source VPN protocol — via a Houston UI module called Wireshield.
ZFS
Why 45Drives builds single-server storage on ZFS, the open-source filesystem built to never silently lose your data.
New pieces of the stack get added here as they’re documented — this list grows automatically.
