Synology RS4021xs+ NAS Server: 64TB, Xeon CPU, 2x10GbE

The Synology RackStation RS4021xs+ is a high-performance rackmount NAS server engineered for growing businesses that require robust data management solutions in multi-user environments. Designed as an adaptable 16-bay system, it delivers substantial performance and reliability to handle rigorous workloads efficiently. This server is equipped with a Xeon D-1541 8-core processor running at 2.1GHz, ensuring powerful computational capabilities for demanding tasks such as data processing, virtualization, and application hosting.

The system includes 64GB of DDR4 ECC UDIMM memory, which enhances stability and performance under heavy workloads by reducing the likelihood of memory errors. This capacity supports smooth operation in environments where multiple users access shared resources simultaneously. For storage, the RS4021xs+ features a total of 64TB of internal storage, composed of sixteen 4TB SATA 2.5-inch SSDs. This configuration provides ultra-fast data access speeds and high throughput, making it ideal for applications requiring rapid data retrieval and processing.

Network connectivity is extensive and versatile, featuring four RJ-45 1GbE LAN ports alongside two RJ-45 10GbE LAN ports. Both sets support link aggregation and failover capabilities, ensuring reliable and redundant network connections critical for business continuity. Additional connectivity options include two USB 3.2 ports for direct device integration and two expansion ports for future scalability or additional hardware integration.

The file system utilizes Btrfs alongside EXT4 to provide advanced data integrity features such as snapshots, checksums, and efficient storage management. These capabilities enhance security and simplify backup processes while maintaining performance efficiency. The Btrfs file system also facilitates advanced iSCSI LUN services for flexible storage virtualization options.

The server operates using Synology DSM (DiskStation Manager), a comprehensive operating system designed specifically for Synology NAS devices. DSM provides an intuitive interface that enables users to manage data storage, security protocols, user permissions, and network settings with ease. It ensures reliable data security through encryption mechanisms and centralized management tools that support large-scale deployments across multiple users.

The RS4021xs+ comes with a rail kit included in the box, facilitating easy installation into standard rack enclosures without the need for additional mounting accessories. The unit is supplied in a sealed box but does not include pre-installed hard drives or memory modules; these components are available separately and require installation by the user.

In conclusion, the Synology RackStation RS4021xs+ offers a compelling solution for small to medium-sized businesses seeking scalable storage infrastructure with high performance and reliability. Its combination of powerful hardware specifications, robust networking capabilities, advanced file systems, and user-friendly software makes it an ideal choice for environments that demand secure, fast access to large volumes of data across multiple users without compromising on performance or scalability.
