Enterprise Storage for every budget.
The most affordable TrueNAS unified storage arrays are designed with enterprise features, high-availability, and reliability at an entry-level cost. Available in two models, the TrueNAS X10 and X20 provide unified file, block, and object storage, and are available in single or dualcontroller, hybrid or all-flash configurations. The TrueNAS X-Series offers excellent reliability and affordability for small and medium IT environments.
The TrueNAS X-Series arrays combine 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 inherits the rich functionality and Open Source economics of FreeNAS® and adds Enterprise-class capabilities.
Every TrueNAS enterprise storage array supports unified block, file, and S3-compliant object storage protocols. Its modular hardware architecture conserves power, space, and cooling while supporting multiple applications with its hybrid flash and disk storage pools. Optional High Availability 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 X-Series fits a wide range of applications from file and media storage to business continuity, video surveillance, and many others. The TrueNAS X-Series provides data integrity, reliability, and ease-ofmanagement for business that never sleeps.
FLASH-ASSISTED PERFORMANCE
Solid-state performance at spinning-disk capacity and cost. TrueNAS leverages ZFS to merge multi-layer DRAM and flash cache with high-density spinning disks: system RAM and SSDs are used to cache reads and writes while HDDs store the data.
The performance of RAM and SSDs are orders of magnitude faster than HDDs, while their power requirements are much lower. TrueNAS lets you increase performance and scale capacity while conserving power and saving money.
SELF-HEALING DATA PROTECTION
Data integrity is the name of the game, and TrueNAS leaves nothing about your data to chance. In-flight data corruption is automatically detected and repaired before it ever reaches disk, and bit rot and data decay are identified and scrubbed clean. This ensures data is always pristine. Simply put, what you store on a TrueNAS storage solution today will remain intact for as long as it’s in service.
INTELLIGENT STORAGE OPTIMIZATION
TrueNAS maximizes storage efficiency by offering compression, deduplication, and thin provisioning at no extra cost. The TrueNAS Adaptive Compression (TAC) algorithm efficiently boosts storage performance while maximizing storage 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 over any data too inefficient to be worthwhile.
UNLIMITED SNAPSHOTS & REPLICATION
Most storage appliances require additional licenses for advanced features – but not TrueNAS. Unlimited file version retention, restoration, and replication are at your fingertips. Data is automatically protected locally against unintentional alteration, such as 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 the power of TrueNAS, any data protection or disaster recovery policy is simple to implement and maintain.
Features:
True Protection
TrueNAS integrates with all major backup vendors and virtual machine environments, and is certified with Veeam Backup and Replication, Citrix and VMware. It supports VMware snapshots, and has a vCenter plug-in. It is also integrated with Microsoft CSV, ODX, and VSS.
True Scalability
ZFS is a future-proof 128-bit “scale up” file system that is designed for decades of continuous use. TrueNAS grows from hundreds of GBs to 10PB per system and is designed to make the increase in capacity painless.
True Flexibility
TrueNAS offers flexibility of choice, providing SMB, AFP, and NFS for file storage, iSCSI and Fibre Channel for block storage, and S3-compatible APIs for object storage. Every common operating system, hypervisor, and application is supported. TrueNAS uses OpenZFS to provide unlimited point-in-time snapshots, allowing you to roll back and access previous data versions. TrueNAS is a proven way to mitigate virtual machine corruption, user error, and ransomware attacks.
True Performance
The flash-turbocharged TrueNAS delivers a perfect balance of price and performance that puts many all-flash arrays to shame. It uses TrueCache™ to leverage RAM, flash storage, and spinning disks for flash-like performance with spinning-disk capacities and economics.
True Freedom
TrueNAS is the enterprise version of FreeNAS, the #1 software-defined storage operating system. With TrueNAS, iXsystems has delivered the enterprise-grade OpenZFS file system to more users than anyone. We pride ourselves on working closely with the Open Source community to help make OpenZFS the greatest filesystem ever written.
Unified

The lack of unified support in many other storage arrays impacts the ability to use and share data worldwide, increasing storage TCO. TrueNAS provides:
- Unified access of multiple files using various block, file, and object protocols.
- Reduction in the number of storage arrays required to support applications.
- The ability to build a private cloud instead of relying on expensive cloud storage services.
Economical

As a true enterprise storage platform, TrueNAS delivers models that meet very demanding performance and capacity requirements. The top of the line TrueNAS M50 has up to four active 100GbE ports, 3TB of RAM, 32GB of NVDIMM write cache, and up to 15TB of NVMe flash read cache. Solid-state performance with spinning-disk capacity and cost—that’s what you get with a flash-turbocharged TrueNAS. iXsystems also offers an all-flash array, the TrueNAS Z50 TrueFlash, which combines the performance of flash with the powerful enterprise features and elegant simplicity of a TrueNAS hybrid storage array, making it ideal for latency-sensitive and demanding mission-critical workloads. There’s no question that TrueNAS is hands-down the best value in enterprise-class storage.
Enterprise Ready

TrueNAS guarantees data integrity and has redundancy throughout the storage array. It includes instant snapshots and clones with local and remote replication. Windows users can easily integrate snapshots with the view previous versions attribute of files from within Windows Explorer. Get simple and efficient recovery points for VMs and business-critical applications.
Not everything goes as planned all the time, and how your vendor reacts in critical situations is what makes the difference. We have built our business on quality of service and support, and we want you to view our team as an extension of yours. iXsystems offers tiers of support to meet your organization’s specific needs. We support your storage deployment so you don't end up having to scramble for a costly services or additional hardware. In fact, customers say that the support they get with TrueNAS is first rate and they prefer our support to other vendors.
Fast

With TrueNAS there are no long waits for filesystem checking at boot time. TrueNAS uses TrueCache™ to combine DRAM and non-volatile flash with high-density spinning disks to create a flash-turbocharged architecture. TrueCache uses algorithms to ensure data is stored on the fastest system storage media. By utilizing these algorithms in combination with flash-based read and write caching, performance speed increases by orders of magnitude at minimal cost.
TrueNAS intelligently compresses what it can and skips over any data too inefficient to be worthwhile. Deduplication finds shared blocks between different applications or VMs. This storage optimization reduces the size of data written to storage media, increases performance, and gets the most out of every byte of storage.
Highly Available

TrueNAS storage is designed for around-the-clock applications. When data grows, the expansion of TrueNAS storage is simple and non-disruptive.To upgrade any TrueNAS model to High Availability, simply add a second storage controller. High Availability ensures data is always available, meeting almost any storage requirement and lowering TCO to levels previously not thought possible with an enterprise storage array. With TrueNAS, downtime isn’t an option.
