Synology FS2017 Hardware Features

Synology FS3017 Hardware Features

High-Powered CPU Performance

The FS2017 NAS contains an Intel Xeon D-1541 processor, and the FS3017 contains dual Intel Xeon 6-core processors with NUMA technology. These processors represent the best of the best when it comes to Intel’s server processing lineup, and the dual processor system equipped with the F3017 NAS ensures that you’ll be able to render images and blaze through file systems at incredible speeds. These CPUs are ready and willing to host a variety of virtual machines simultaneously or provide backup services for your entire workforce.

Incredible RAM Capacity

The FS2017 and FS3017 both come with 16GB of DDR4 ECC RDIMM RAM right out the gate, but the FS2017 is designed to contain up to 128GB of RAM, and the FS3017 can be upgraded to run a whopping 512GB of RAM. With that much RAM, you’re able to run a practically unlimited number of processes simultaneously with plenty of breathing room to spare. As you add more and more RAM capacity, you’ll find that a fully-stocked 512 gigabytes doesn’t seem like such a lofty goal after all.

Lightning-Fast IOPS

Both the FS2017 and the FS3017 can handle a blindingly fast number of input/output operations per second (IOPS). The FS2017 can process up to 90,000 iSCI 4K random write IOPS, and the FS3017 is equipped to handle over 200,000 4K random write IOPS, which means that you’ll never encounter a bottleneck with these high-powered NAS solutions.

Super-Expandable Drive Bays

While both the FS2017 and the FS3017 have 24 SSD bays each, they also both feature expansion functionality. With the optional RX2417sas expansion unit, you can add an extra 24 bays to either the FS2017 or the FS3017. But that’s not all; both of these high-end NAS solutions are capable of connecting to two RX2417sas units, which means that both the FS2017 and the FS3017 can be expanded into 72-bay NAS solutions. This optional expansion unit has the ability to triple your available SSD storage space.

RAID F1 for Extended SSD Lifespan

Many NAS solutions distribute workloads equally between each SSD drive in their array. However, this equal distribution protocol tends to make every SSD drive in your NAS fail at once. Synology has solved this issue with the FS2017 and FS3017 NAS systems by equipping them with RAID F1 technology, which staggers the workload between the drives in your NAS. This protocol ensures that all of your drives won’t fail at once, which protects the integrity of your data.

Advanced Btrfs File System

The FS2017 and FS3017 are equipped with the cutting-edge Btrfs file system. This file system is the most efficient data management infrastructure in deployment today, and its User Quota System offers server administrators total quota control over user accounts and shared folders. Snapshot Replication saves storage capacity by offering 1,024 shared folder backups and 65,000 system-wide snapshots, and Btrfs detects and heals files automatically without any need for user intervention. This file management system makes it easier than ever to recover your data.

Fully Stocked DiskStation Manager UI

Synology’s DiskStation Manager (DSM) user interface offers everything you need to manage your server and your entire network. This comprehensive UI features a clean and simple interface, and it is loaded with apps that make it easy to control the inner workings of your NAS. CMS allows you to manage multiple NAS systems from a central location, which is additionally helpful with the FS2017 and FS3017 since these NAS solutions are generally used as additions to traditional HDD servers. DSM also features MailPlus, which is a secure and reliable platform for handling the mail system for your company. Hyper Backup stores multiple backup versions with block-level incremental backup, and it also offers cross-version deduplication to save storage space. Plus, Cloud Station Suite synchronizes cross-platform data to maintain the same file version on all of your connected devices.

Dual Power Supplies for Uninterrupted Workflow

The FS2017 and FS3017 both contain dual power supplies. Traditionally, if something went wrong with your power supply, your NAS would be out of commission until the power supply could be replaced. With dual power supplies, however, it is possible to automatically switch over to the other power supply if one fails, which ensures that you’ll retain steady access to your data and enjoy uninterrupted workflow operations.

Comprehensive Warranty and Replacement Services

Both the FS2017 and the FS3017 come with five-year warranties. These warranties cover manufacturers defects, and they also provide hardware replacement if any of the components in your SSD NAS system wear out. They also include technical support by phone or email, which ensures that you’re always able to reach out if something goes wrong. These surprisingly comprehensive warranties ensure that you’ll get the greatest possible return from your investment in these high-end NAS systems.

If something goes wrong with your FS2017 or FS3017 that your warranty can’t fix, however, Synology offers a replacement service called SRS that can provide you with a replacement unit overnight if you’re located in an eligible region. This service eliminates downtime and ensures uninterrupted business continuity.


The FS2017 contains four 1GbE RJ-45 ports, and it also has two 10GbE RJ-45 ports. It has two USB 3.0 ports, and it’s also equipped with a console port for peripherals. In addition, this NAS has a PCIe 3.0 slot, and it has two ports that can admit expansion drives. The FS3017 has two 10GbE RJ-45 ports, and it also has a console port. It has two USB 3.0 ports, and it has two PCIe 3.0 slots. It is also equipped with expansion ports.

Application and Use Case

The FS2017 and FS3017 are enterprise-class NAS solutions that are best equipped for the needs of medium-sized enterprise applications with 200-1,000 employees. Since these high-end Synology NAS systems are optimized for SSD drives, they work best when they are paired with traditional NAS systems that contain HDD drives, which means that the FS2017 and FS3017 should generally only be used as supplemental NAS solutions and not as primary storage and backup targets. Since these NAS systems are designed to provide lightning-quick read I/O speeds, they are best applied in scenarios where large teams need to rapidly share high-definition video projects or server administrators need to be able to deliver dozens of simultaneous virtualization environments. The FS2017 and FS3017 are also ideal for mail server and database applications. The FS2017 costs $6,299.00 without any drives installed, and it costs between $9,153.00 and $15,949.00 when equipped with 8TB-48TB of SSD storage capacity. The FS3017 costs $9,975.00 without any drives installed, and it costs between $13,058.00 and $20,455.00 when equipped with 8TB-48TB of SSD storage capacity.
