Scale is a Linux-based distribution feature that supports the addition of multiple tools beyond what you need for managing a single node. In other words, you’re looking at full functionalities, such as KVM virtualization, container operations, and clustered storage.

While the feature may not be available yet, experts predict it will be available as a production system in the next 12 months. Why is this feature such a big deal? Because it allows you to build an edge cluster and deploy three interconnected Mini X+ units instead of a single one. If you ask anyone in the STH community, they’ll tell you why.

Part 6. TrueNAS Mini X Performance Numbers

Since TrueNAS Mini X+ is a FreeBSD ZFS-based solution, getting the correct performance numbers isn’t an easy task at all. You have SMB, iSCSi, and NFS protocols, CPU/network vs. disk performance, caching drives, ZFS-native drive configuration, WD Red Plus drive, and more.

Nailing the numbers accurately is a bit of a stretch. However, you can focus on the key selling points, such as CPU performance. Just install Linux Ubuntu in one of the SSDs and run CPU testing.

CPU performance
