After a very successful development cycle with 200+ trial users, the first version of TrueNAS SCALE is now available. As our initial community post and blog on SCALE indicated, TrueNAS SCALE is defined by its acronym:
Scale-Out ZFS: Capacity & Performance Converged compute and storage Active-Active reliability Linux containers; Docker, K8s, and KVM Easy Setup & Management
TrueNAS starts from the TrueNAS 12.0 base which includes OpenZFS 2.0, all the storage services, the middleware to coordinate these, and the web UI to present a user-oriented view of the system. This base has been tested by hundreds of thousands of users over the last few years. The new capabilities being added are based on Debian Linux and these define the new opportunities for SCALE:
KVM Virtualization: Mature Hypervisor with good reliability, Guest OS support, and Enterprise features.
Kubernetes: Applications can be single (docker) containers or “pods” of containers.
Scale-out ZFS: SCALE will enable datasets to be defined as ZFS datasets or cluster datasets which span multiple nodes and ZFS pools. Cluster datasets will have a variety of redundancy properties and still support ZFS snapshots.
Unlike other Hyperconverged Infrastructure solutions, TrueNAS SCALE will have deployment benefits as a single node, a dual-node “HA” system, or as a cluster of multiple nodes. Start with a single node system and in the future, you will be able to scale-out.
