Synology RS4021xs+ NAS Server: Powerful Performance with 64TB SSD & 10GbE

The Synology RackStation RS4021xs+ is a high-performance Network Attached Storage (NAS) server designed for businesses that require robust data management, security, and scalability. It features an Intel Xeon D-1541 8-core processor with a base clock speed of 2.1GHz and a turbo boost up to 2.7GHz, ensuring efficient handling of data-intensive tasks. With 64GB of DDR4 ECC UDIMM memory, the system is optimized for reliability and performance in multi-user environments. The NAS includes 64TB of storage capacity using 16 x 4TB SATA 2.5" SSDs, offering ultra-fast read and write speeds for critical business data.

The RS4021xs+ is engineered for service continuity and mission-critical operations. It includes redundant power supplies and hot-swappable fans to prevent downtime in the event of hardware failure. The Synology High Availability (SHA) feature enables active-passive clustering with minute-level failover, ensuring uninterrupted access to data even during disasters. This makes it an ideal solution for businesses that rely on continuous data availability.

The NAS also supports virtualization environments through Synology iSCSI storage, which integrates seamlessly with popular virtualization platforms like vSphere, Hyper-V, XenServer, and Cinder. Features such as VAAI integration, Windows Offloaded Data Transfer (ODX), and the Synology Storage Console simplify storage provisioning and management in virtualized setups.

The RS4021xs+ comes with dual-port 10GbE LAN connectivity, providing high-speed network performance for large data transfers. Additional ports include four 1GbE RJ-45 LAN ports (with support for link aggregation and failover), two USB 3.2 ports, and two expansion ports for future scalability. The Btrfs file system supports advanced LUN iSCSI services and enhances data integrity and performance.

It is important to note that while the hard drives and memory are included in the package, they are not pre-installed and require setup by the user. The system runs on Synology DSM (DiskStation Manager) operating system, which provides a user-friendly interface for managing storage, security, and other NAS functions.
