Synology RackStation RS4826xs+ 12-Bay Rackmount NAS

Synology RackStation RS4826xs+

High-Performance Enterprise Storage: Scalable up to 48 Bays

The Synology RS4826xs+ is a premier, all-in-one 2U rackmount server designed for centralized data management, secure multi-platform backup, and high-tier surveillance operations. Engineered to scale dynamically alongside your enterprise requirements, it supports up to 48 drives via plug-and-play expansion units, versatile high-speed networking upgrades, and smart automated storage tiering. Operating on the proven Synology DiskStation Manager (DSM) platform, it guarantees continuous service availability, robust physical and data security, and seamless private cloud collaboration.

The Synology RackStation RS4826xs+ arrives as an elite centerpiece of the new 2026 lineup, serving as the direct evolutionary successor to prior-generation high-capacity enterprise units like the RS4021xs+. This next-generation 2U 12-bay rackmount storage powerhouse delivers a massive leap in computing efficiency, upgrading to a highly optimized 8-core Intel Xeon D-1739 processor. Featuring built-in dual 10GbE networking, a dedicated out-of-band (OOB) management port, three Mini-SAS HD expansion ports, and dual redundant power supplies, the RS4826xs+ is built from the ground up for intensive, mission-critical corporate storage architectures.

Choosing a RackStation XS model like the RS4826xs+ over a standard RackStation Plus unit (such as the RS822+) offers clear infrastructure advantages for demanding business deployments. While the Plus series serves as an efficient edge storage layer built around lower-power processors and standard 1GbE ports, the XS family delivers true enterprise-tier processing via multi-core Xeon CPUs, extensive scale-out capability up to 48 drives, and native 10GbE connectivity out of the box. Furthermore, the XS tier safeguards your physical deployment with a comprehensive 5-year hardware warranty (compared to the 3-year term of Plus models) and utilizes advanced ECC RDIMM memory modules to protect against system crashes and spontaneous data corruption.

Key Features:

• High Performance for Intensive Workloads: Driven by an Intel Xeon D-1739 8-core, 16-thread processor, delivering over 135,000 4K random write IOPS and blistering sequential speeds of up to 6,200/3,700 MB/s read/write throughput.

• On-Demand Capacity Expansion: Grows effortlessly with your business by scaling from 12 base bays up to 48 drive bays (utilizing three 12-bay Synology RX1225RP expansion units connected via high-bandwidth Mini-SAS HD ports).

• Versatile Built-in & Expandable Networking: Features dual native 10GbE RJ-45 ports supporting Link Aggregation for automated network failover. Dual PCIe 4.0 slots allow effortless expansion via 10/25GbE NICs and Fibre Channel adapters.

• Remote Diagnostics & OOB Management: Simplifies IT fleet management with a dedicated Out-of-Band (OOB) management LAN port, letting administrators remotely diagnose, review critical logs, and control powered-down devices.

• Intelligent Automated Storage Tiering: Features Synology Tiering to maximize storage economics, automatically offloading colder, infrequently accessed data to lower-cost storage tiers while reserving high-performance arrays for active workloads.

Why Choose the RS4826xs+:

• Flexible Flash & Accelerated Caching: Deploy flexible configurations leveraging all-flash or hybrid storage setups. Use premium SATA SSDs for active storage volumes, or install compatible M.2 NVMe drives via an optional PCIe adapter card to create an ultra-fast read/write cache without occupying primary 3.5″ drive bays.

• Secure Private Cloud Collaboration: Elevate cross-team output with the license-free Synology Office Suite. Concurrently edit documents, spreadsheets, and presentations in real time, map centralized file management via Synology Drive with granular sharing permissions, and maintain full data ownership with an on-premises Synology MailPlus server.

• Generative AI Integration: Accelerate daily business workflows using Synology Office Suite AI to seamlessly draft, summarize, and analyze records. Features a dedicated AI Console that locally masks sensitive identifiers (credit cards, SSNs, names) to protect data privacy before communicating with external AI providers.

• Efficient Multi-Site Synchronization: Simplify global team operations with Synology Hybrid Share, combining cloud storage elasticity with fast local access speeds. Automate site-to-site synchronization using NAS-to-NAS replication or connect to public cloud providers like Amazon S3, Backblaze B2, Dropbox, Google Cloud, Microsoft Azure, and OpenStack Swift.

• Comprehensive Infrastructure Protection: Secure endpoint environments using the license-free Active Backup Suite to centralize physical or agentless backups for Windows/Mac/Linux systems, VMware and Hyper-V virtual machines, and cloud instances like Microsoft 365 and Google Workspace.

• Maximum System Availability Safeguards: Eliminate single points of failure using dual redundant hot-swappable power supplies, hot-swappable system fans, and online volume management. Pair two identical servers using Synology High Availability for minute-level automated failover.

• Advanced Multi-Layered Data Security: Defend enterprise data against ransomware or malicious deletion with full-volume encryption, WriteOnce shared folders, and tamper-proof WORM-powered immutable snapshots triggered automatically by machine-learning-driven Active Insight fleet monitoring.

• Virtualization-Ready Performance: Seamlessly integrate into existing enterprise storage rings with full certifications for VMware vSphere, Microsoft Hyper-V, Citrix XenServer, and native OpenStack Cinder block storage, enhanced by hardware-level Windows ODX and VMware VAAI offloading.

• Scalable Centralized Video Surveillance: Transform the server into an advanced, subscription-free Network Video Recorder (NVR) with Synology Surveillance Station. Manage up to 125 IP cameras centrally across hundreds of physical locations using the Synology Centralized Management System (CMS).
