In their own words
LINBIT DRBD
LINBIT DRBD is open-source distributed replicated block storage software for Linux, used in high-availability setups. Its kernel driver mirrors writes to one or more peer nodes; in synchronous mode, a write completes only after local and peer storage completion events. Reads can be served locally without network traffic, and the data path avoids user-space components. DRBD combines the kernel driver with user-space management applications and shell scripts, and its command-line interface can manage large clusters without relying on cloud, virtualization, or container platforms. It supports TCP/IP and RDMA/Verbs transports, including InfiniBand, iWARP, and RoCE. The DRBD 9 guide documents TLS encryption for TCP transport. LINBIT also offers WinDRBD for Windows and says its subscriptions integrate with Kubernetes and other major platforms. The open-source community version is free; LINBIT Starter is $1,000 a year, starting from $1,000 for two nodes. The company is headquartered in Vienna, Austria.
SeaweedFS
SeaweedFS is a distributed storage system that serves S3 objects, Iceberg tables, and POSIX files from one cluster. It supports S3, POSIX mounts, HDFS-compatible access, an Iceberg REST catalog, and WebDAV. Its built-in Iceberg catalog supports queries with Spark, Trino, Dremio, and DuckDB. The product describes scaling from gigabytes to petabytes and supporting billions of files. Development and testing under 25 TB are free, but production deployments require a paid license regardless of size. Monthly capacity licensing is $2 a month, based on used storage including replication or erasure-coding overhead; yearly licensing is $20 a year. Enterprise features include deleted-file recovery within a configurable retention window, point-in-time restoration, repair of missing or corrupted erasure-coding shards, and OIDC sign-in with role mapping. The free 25 TB trial limits deleted-file recovery retention to one hour. Enterprise support is optional and priced separately from capacity licensing. Community support is free and has no guaranteed response time. SeaweedFS is available for Linux, macOS, and Windows, with API access and self-hosted deployment.
