RS1226+

Overview

Synology RS1226+ 8-Bay Rack NAS
The Synology RS1226+ is a powerful 2U rackmount NAS designed to provide dependable, scalable storage for businesses, distributed environments and edge deployments. With an AMD Ryzen V1500B processor, 4GB of DDR4 ECC memory and eight hot-swappable drive bays, it provides a flexible foundation for file storage, backup, collaboration, surveillance and other business applications. The system also includes two 2.5GbE LAN ports, dual M.2 NVMe slots and PCIe expansion capability for future upgrades.

Description

The Synology RS1226+ combines reliable storage with the flexibility needed for growing business environments. Its eight front-accessible drive bays support 3.5-inch SATA hard drives or 2.5-inch SATA SSDs, while an expansion unit can increase the system to as many as 12 drive bays. This allows storage capacity to grow as data requirements increase without replacing the main NAS.

The built-in dual 2.5GbE RJ-45 ports support Link Aggregation for improved network performance, load balancing and network failover. For organisations that require additional throughput, the PCIe expansion slot can accommodate compatible 10GbE or 25GbE networking options.

Two integrated M.2 2280 NVMe slots provide another useful upgrade path. Compatible NVMe SSDs can be used for SSD caching, helping reduce latency and improve IOPS when working with HDD-based storage pools. This makes the RS1226+ suitable for environments where both storage capacity and responsive data access are important.

With Synology DiskStation Manager, the RS1226+ can support a wide range of business applications from a central platform. It can be used for file sharing and synchronisation, endpoint and virtual machine backup, cloud data protection, multi-site synchronisation and IP camera management.

Features

High Performance 2U Rackmount Storage
The RS1226+ is designed to deliver strong networked storage performance, with sequential read and write throughput of more than 2,300 MB/s and 1,500 MB/s respectively under suitable configurations. Its rackmount 2U design makes it a practical choice for server rooms and data centre environments where rack space matters.

Key performance and connectivity points include:

• AMD Ryzen V1500B processor
• 4GB DDR4 ECC SO-DIMM memory
• 2 memory slots for future memory expansion
• 8 hot-swappable drive bays
• 2 x 2.5GbE RJ-45 LAN ports
• 2 x USB 3.2 Gen 1 ports
• 1 x USB Type-C expansion port
• 1 x PCIe Gen3 x8 slot with x4 link
• 2 x M.2 2280 NVMe SSD slots
• Up to 12 drive bays with compatible expansion hardware
• 2U rackmount form factor

Flexible Storage Expansion
Eight drive bays provide substantial storage capacity from the start, while support for an expansion unit allows the RS1226+ to reach up to 12 drive bays and as much as 288 TB of raw storage with suitable drives and expansion hardware. Hot-swappable drive bays also make drive maintenance and replacement more convenient, helping reduce disruption to storage operations.

The two built-in M.2 NVMe slots allow SSD caching without consuming the main front drive bays. This can be particularly useful when large HDD arrays need faster access to frequently used data.

Reliable Network and System Availability
For businesses that depend on continuous access to their data, the RS1226+ provides several options for improving resilience. The two 2.5GbE ports can be bonded using Link Aggregation, supporting load balancing and automatic network failover when configured with compatible network infrastructure.

Two RS1226+ systems can also be paired using Synology High Availability to create an active/passive server cluster. This setup is designed to improve service continuity by allowing workloads to move to the secondary system if the primary server experiences a failure.

Upgrade Networking as Requirements Grow
The built-in 2.5GbE connectivity provides a useful starting point, while the PCIe expansion slot gives organisations the option to move to faster networking later. Compatible networking adapters can provide 10GbE or 25GbE SFP+/SFP28 connectivity, as well as additional Ethernet options depending on the deployment.

This makes the RS1226+ suitable for businesses that want to build a storage platform that can adapt as network traffic, user numbers and application workloads increase.

Private Cloud File Sharing and Collaboration
The RS1226+ can provide a central private cloud environment for organisations that need secure access to files across multiple locations. Users can access and synchronise personal and shared data through desktop applications, mobile devices and web browsers.

Administrators can apply detailed file and folder permissions, manage sharing access and maintain records of file activity. Automatic synchronisation helps keep data consistent across connected devices and locations.

Multi-Site Data Synchronisation
For businesses operating across multiple offices or locations, Synology provides several ways to keep data synchronised. NAS-to-NAS synchronisation can be configured for one-way or two-way workflows, helping keep selected files and folders current across sites.

The RS1226+ can also connect with public cloud platforms such as Amazon S3, Backblaze B2, Dropbox, Google Cloud Storage, Microsoft Azure and OpenStack Swift. Encryption, bandwidth controls and configurable synchronisation options provide additional control over how data moves between local and cloud storage.

Centralised Backup for Business Data
The RS1226+ can serve as a central backup platform for Windows, Mac and Linux computers, Synology systems and supported VMware and Hyper-V virtual machines. Active Backup for Business helps organisations centralise backup tasks and manage recovery from a single system.

Microsoft 365 and Google Workspace data can also be backed up to protect cloud-based information against accidental deletion and other data loss scenarios. Scheduled backups, file versioning and block-level deduplication can help reduce storage requirements while maintaining multiple recovery points.

Data Protection and Recovery
Synology backup applications provide options for protecting system data, applications and configurations. Backups can be stored on other storage destinations, including compatible Synology C2 Storage services.

Depending on the backup configuration, recovery options can include complete system restoration through bare-metal recovery or retrieval of individual files. Features such as scheduled backups, access controls, encryption, deduplication and multi-version retention provide additional flexibility when creating a business backup strategy.

Business NAS for Storage, Backup and Surveillance
Beyond traditional file storage, the Synology RS1226+ can support a variety of business workloads. It can be used for centralised document storage, team collaboration, backup infrastructure, remote file access, synchronisation and surveillance applications. Synology states that the system can manage up to 40 IP cameras when configured with the appropriate surveillance software and licensing.

This broad application support makes the RS1226+ more than a basic network storage device. It can act as a central business data platform while leaving room for additional storage, networking and SSD performance upgrades.

Synology RS1226+ Part Number / SKU
The part number / SKU for this model is RS1226+. This identifies the Synology RS1226+ Plus Series 8-bay rackmount NAS described above.

Who Is the RS1226+ Suitable For
The Synology RS1226+ is well suited to businesses, IT departments, server rooms and distributed organisations that need dependable rackmount storage with room for future expansion. Its combination of ECC memory, hot-swappable drives, 2.5GbE networking, NVMe caching and PCIe expansion makes it suitable for both general storage and more demanding business deployments.

For organisations that need centralised file access, backup, synchronisation, surveillance or private cloud services in a compact rackmount chassis, the RS1226+ provides a flexible platform that can grow with changing requirements.
