Enterprise-Grade Open Storage

Built to maximize storage capacity, performance, and uptime, the M-Series is the TrueNAS® flagship line of appliances designed with the flexibility to address an array of demanding storage requirements and adapt as needs change over time. With high-availability options and advanced data management tools, the TrueNAS M-Series safeguards data for mission-critical operations where downtime is not an option.

Performance & Scale without Compromise

All-flash or hybrid disk and flash? The M-Series can be both. Combining vast system RAM, NVDIMM, and NVMe flash as layered cache provides industry-leading read and write efficiency and optimizes the performance of the primary storage media. Flash pools are supercharged, and high-density disk pools deliver low latency flash performance at disk capacity and cost. Fusion Pools, comprised of both disk and flash together, deliver the best of both worlds. With up to four 100Gb/s network ports per controller, the TrueNAS M-Series is designed to move terabytes at maximum speed.

Storage You Can Rely On

The TrueNAS M-Series offers unmatched data reliability in both software and hardware. The OpenZFS file system is the last word in data protection with copy-on-write and bit-rot detection ensuring the integrity of your data from write to read. Dual controllers and high- availability options ensure over 99.999% uptime to maintain business operations and keep applications running around the clock.

Hardware Management: Simplified.

Servicing an M-Series system is made easy by the modular, tool-less hardware design. Additional integrated enclosure management capabilities save time and effort by providing graphical visualization of the system in the UI, making it easy to monitor the state of your system from a single screen. If performance or capacity needs change over time, it’s as simple as a non-disruptive upgrade to higher-end M-Series controllers.

Scale Up or “SCALE” Out

Begin building the foundation of your scale-out, hyper-converged virtualization infrastructure with SCALE or use Enterprise for high-performance, ultra-reliable local HA storage. Expand to over 20 PB on a single M60 head unit with support for up to 12 expansion shelves, or use TrueNAS SCALE to cluster over 100 systems together for massive capacity and performance.

Professional White-Glove Support

In the unlikely event that a failure does happen, you can rest easy knowing that all TrueNAS M-Series systems are fully backed by our US-based professional support team. Whether you need 24×365 support or on-site repair, flexible Bronze, Silver, and Gold support options are available to help you meet your goals.
