Infortrend EonNAS Pro 850 is an 8-bay Tower NAS designed to help SMB users optimize file sharing, IP-SAN applications and data backup. Powered by Intel i3 Dual-Core Processor 3.3 GHz with exceptional 4 GB DDR3 RAM, the Infortrend EonNAS Pro 850 offers enterprise-level features that can be easily accessed among local and remote workstations featuring Windows, Mac or Linux platforms and configured through an intuitive user interface. Features such as data deduplication, unlimited snapshot, pool mirror, ZFS Hierarchical Checksum, corrupt data self-healing, compression and remote replication deliver high efficiency and excellent reliability.

Advanced File Sharing and IP SAN Support

With comprehensive network protocol support on EonNAS Pro 850, files can be easily shared among local and remote workstations featuring Windows, MAC or Linux platforms. Access control for folders and subfolders allows you to easily meet different user requirements in the office. For consolidated management, you can also choose to import account information from Windows Active Directory (AD) to EonNAS Pro 850.

The built-in iSCSI target support on EonNAS Pro 850 enables you to deploy IP SAN and serve applications such as mail servers, databases and virtualization. All EonNAS Pro 850 models are compatible with VMware, Hyper-V and Citrix virtualization platforms. With CHAP authentication, iSCSI data can be kept secure from unauthorized initiators. Capacity utilization is further enhanced by thin provisioning technology. By dynamically allocating capacity to applications on an as-needed basis, EonNAS Pro 850 eliminates pre-allocated yet unused data volumes and simplifies storage resource management. In addition, EonNAS Pro 850 supports MPIO and MC/S to help users achieve data path failover, load balancing, and enhanced performance.

File sharing

Comprehensive Backup Options

With EonNAS Pro 850, users can backup data in various ways. EonNAS Pro 850 comes with free licenses for FarStone TotalRecovery Pro backup software. You can leverage this solution, or other compatible third-party software, to backup PC and server data. For Mac users, EonNAS Pro 850 supports Apple Time Machine. Data backup to or from external disk drives can be achieved via USB or eSATA connections. You can also configure USB-based data transfer for one-touch-copy, enabling you to complete a data copy with a single button press (EonNAS Pro 850) when an external drive is connected via the USB port at the front of the EonNAS Pro 850 chassis.

Comprehensive backup options

Optimized Storage Capacity Utilization

EonNAS Pro 850 ensures you get the most out of your available storage capacity. EonNAS Pro 850 comes with inline, block-based data deduplication, a feature often seen only in enterprise storage solutions. Duplication calculations are performed as each new data block enters deduplication-enabled volumes. When the system sees that an identical block is already present in the volume, the new block will be discarded and only a pointer will be created for reference to the existing block. By removing duplicate data blocks, the technology offers storage space savings of around 90% in backup applications, 70% in virtualization environments and 40% for common office files.

In-Line Deduplication

Robust Data Protection

Core business assets are protected with robust, enterprise-class features. EonNAS Pro 850 features RAID protection, which ensures data stays intact even during simultaneous failures of up to two disk drives. When a drive failure occurs, a pre-assigned hot spare will be automatically leveraged to rebuild the original RAID configuration. In addition, disk drives are hot-swappable, meaning they can be replaced without disrupting your applications on the EonNAS Pro 850 system. In rare cases of system failure, you can quickly restore services simply by removing the drives on the old system and putting them into a replacement system. All your data and settings can be recovered following initial set-up.

RAID protection

The embedded ZFS file system ensures end-to-end data integrity through a hierarchical checksum mechanism. When a data block is created, a checksum of this block is stored in its parent block pointer. Whenever a block is accessed, its checksum is calculated and compared with the stored checksum value for integrity. This unique mechanism allows EonNAS Pro 850 to effectively detect data corruption phenomena that go undetected in other file systems, and automatically repair affected data with ZFS self-healing features.

Excellent Data Protection

The snapshot feature helps you deploy multiple recovery points for iSCSI volumes or shared folders at minimized time intervals and space requirements. In the event of human errors or virus attacks, you can quickly restore data with the snapshot copies. EonNAS Pro 850 will automatically remove snapshot images when the number of snapshots or their retention period exceeds pre-set thresholds.


Remote replication offers scheduled data replication to another EonNAS system or third party device via the rsync protocol. In addition, the pool mirror function supports real-time replication that keeps data in two different EonNAS systems synced at all times, ensuring that a standby system can seamlessly take over operations when the primary system goes down.

Remote replication

User-friendly System Management and Monitoring

System management for the EonNAS Pro 850 is extremely easy. Within less than 15 minutes you can complete the process from power-on to initial set-up. A user-friendly, web-based UI helps you manage your system intuitively. You can easily access all frequently-used features via shortcuts and quickly complete required configurations with step-by-step wizards. EonNAS Pro 850 also supports a dashboard feature to help you monitor real-time system status. EonNAS Pro 850 notifies you of critical system events in a number of ways, such as LEDs, system buzzers, email notifications and SNMP traps.

4 out of 5 eggsGreat NAS with ZFS and support; pricey

Pros: + very stable implementation of Solaris ZFS NAS
+ functional and easy to learn GUI
+ decent performance with base system with i3 CPU, base 4GB memory and two 1GbE NICs
+ backup via eSATA is decent performance (wish there were 2 eSATA interfaces!)
+ support still coming out with firmware updates (last one as of this 2015-11-09 writing was in Oct 2015)
+ well made chassis with drive trays which are interchangeable with some other Infortrend multi-drive NAS and external drive housings
+ very easy to setup usual protocols including SNMP MIB and iSCSI which are not always straightforward in competitive NAS offerings
+ includes 8 licenses for TotalRecovery Pro v9 which are easily acquired by registering on Infortrend web site, but (see below)...
+ Infortrend support is quite responsive, even for owners of just a single EonNAS!

Cons: - pricey, though available through unsupported channels without support
- ZFS is memory and CPU intensive, if you fill up this box with drives and setup a few pools, you will need 16GB of memory!
- though memory and 10GbE COULD be user upgradeable, customer install breaks seal and warranty
- very limited Command Line Interface (CLI) shell
- key features (ZFS clone, ZFS export) not exposed and would be a welcome addition
- has no USB3, only USB2 connections to go with one eSATA
- drive trays are plastic in the EonNAS pro series, compatible metal trays give better heat dissipation
- TotalRecovery Pro v9 not downloadable from manufacturer, only TotalRecovery Pro v10 is available
- customer forum removed from Infortrend web site for customer to customer exchange of product experience opting for filtered FAQs instead

Other Thoughts: If you have been looking for a NAS that exposes features from the ZFS filesystem, then this is the departmental level server to do it!

This is a very stable NAS box, with the fantastic features of ZFS exposed such as deduplication, compression, and incremental backup. Downside is this is expensive through supported channels, and as a closed box, risky to purchase through unsupported channels. The EonNAS 850 is not a new design, but the 3.3GHz i3 + adequate memory are a great combination for a NAS that protects data written to it first and foremost. The other packaging of this departmental level EonNAS Pro series (EonNAS 2x0 and 5x0) are underpowered to get a decent experience with ZFS features especially pool level deduplication, compression, and encryption

Net: I like the EonNAS 850 and am agonizing over WHEN (not whether) to break the Infortrend seal and forego warranty support in order to upgrade memory (and have a better look at the internals!)
