TrueNAS M-Series
TrueNAS M-Series is designed to maximize capacity, performance and uptime of storage.
It is the flagship TrueNAS® appliance, equipped with the flexibility to meet a range of demanding storage requirements and adapt over time as needs change.
With high availability options and advanced data management tools, the TrueNAS M-Series secures data for mission-critical operations where downtime is not an option.

TrueNAS M-Series for Enterprise
All-flash or hybrid disk and flash storage? The M-Series can do both. The combination of extensive system RAM, NVDIMM and NVMe flash as a layered cache provides industry-leading read and write efficiency and optimizes the performance of the primary storage media.
Flash pools are over-compressed, and high-density disk pools deliver flash performance with low latency at disk capacity and cost. Fusion pools consisting of both disk and flash offer 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.
Scale Up or “SCALE” Out
Start building a scalable, 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.
Storage you can rely on
Unsurpassed data security in software and hardware. The OpenZFS file system is the ultimate in data security. Copy-on-write and bit-red detection ensure the integrity of your data from write to read. Dual controllers and high availability options provide over 99.999% uptime to keep your business running and applications running 24/7.
Hardware management and upgrades, simplified
Maintaining an M Series system is simplified by the modular, tool-less hardware design. Additional built-in enclosure management features save time and effort by providing a graphical representation of the system in the user interface, allowing you to monitor the health of your system from a single screen. As performance or capacity requirements change over time, a non-disruptive upgrade to higher-end M-Series controllers is easy.
Professioneller White-Glove-Support
In the unlikely event of a failure, you can rest easy knowing that all TrueNAS M-Series systems are backed by iXsystems’ professional support team in the USA. Flexible Bronze, Silver and Gold support options are available to help you achieve your goals.
TrueNAS M-Series in Detail
Designed for maximum ZFS performance and high availability while keeping storage affordable. With advanced read and write caching and expansion to over 1200 drives, the M-Series is ideal for multi-PB storage. For high-performance applications, all-flash storage with TLC or QLC flash can deliver low latency and very high IOPS at industry-leading prices.
