TrueNAS® M-Series
Powerfully-Scalable Enterprise Storage with Open Source Economics
The flagship TrueNAS M-Series is designed to support TrueNAS Enterprise with high-availability and maximum performance in mind.
Combining open source economics, hardware with high performance and reliability, and top quality support services,TrueNAS M-Series and TrueNAS Enterprise provide enterprise flexibility and scalability with trust and confidence.
The TrueNAS M-Series integrates the flexibility of unified storage, the performance of solid state flash drives, the capacity of hard disks, the simplified management of a powerful web-based user interface, and white-glove enterprise support. TrueNAS Enterprise inherits the rich functionality and open source economics of TrueNAS CORE and adds Enterprise-class capabilities such as High Availability (HA), Fibre Channel and VMware certification.
TrueNAS M-Series is available in four models. TrueNAS M30, M40, M50 and M60 provide unified file, block, and S3-compliant object storage and are available with single or dual-controller, hybrid, or all-flash configurations. Featuring multiple high-speed networking (up to 4x 100 GbE), system memory up to 1.5 TB, NVDIMM and NVMe caching, and up to 20 PB capacity, the TrueNAS M-Series is ideally suited for heavy IT storage workloads, including virtualization, media production, high- speed file sharing, and backup.
The TrueNAS M-Series modular hardware architecture conserves power, space, and cooling while supporting multiple applications with its hybrid flash and disk storage pools. HA ensures storage services are not disrupted, while Intelligent Storage Optimization maximizes storage efficiency with typical data reduction ratios of greater than 2.5x.
The TrueNAS M-Series delivers high-performance, scalability, data integrity, reliability, and ease-of-management with open source economics - for companies that never sleep.
Performance & Scale without Compromise:
Hybrid or All Flash Array? With TrueNAS, you can have both. TrueNAS M-Series leverages industry-leading cache along with open source ZFS by merging DRAM, non-volatile memory (NVDIMM), and flash (NVMe/SSD) with high-density disks to deliver low latency flash performance at disk capacity and cost. With up to four 100 Gb/s network ports per controller, the TrueNAS M-Series is designed to move terabytes at maximum speed.
Self-Healing Data Protection:
Data integrity is the name of the game, and TrueNAS leaves nothing to chance. In-flight data corruption is automatically detected and repaired before it ever reaches disk. Bit rot and data decay are identified and scrubbed clean. With TrueNAS, your data is always pristine.
Intelligent Storage Optimization:
TrueNAS M-Series maximizes storage efficiency by offering compression, efficient snapshots, clones, and thin provisioning at no extra cost. TrueNAS Adaptive Compression (TAC) efficiently boosts performance while maximizing capacity. TAC intelligently adjusts its compression ratio without wasting system resources. Before data is stored, TrueNAS dynamically detects and compresses what it can and skips any data too inefficient to be worthwhile.
Unlimited Snapshots & Replication:
Most storage appliances require additional licenses for advanced features — but
not TrueNAS. Gain unlimited file version retention, restoration, and replication. Data is automatically protected against unintentional alteration, such as from ransomware or
malware, with minimal storage consumption. Data can be replicated locally, remotely, or to the cloud for backups or disaster recovery. TrueNAS snapshots can also be coordinated with VMware snapshots.
With TrueNAS, any data protection or disaster recovery policy is simple to implement and maintain.
