The Synology RackStation RS4021xs+ 16-Bay NAS Enclosure is a reliable and high-performance storage solution designed for enterprise environments. This 3 RU enclosure features 16 drive bays that support both 3.5" SATA hard drives and 2.5" SATA hard drives/SSDs. With the option to expand the capacity by connecting up to 24 additional drive bays using RX1217/RX1217RP expansion units, this NAS can meet the growing demands of data-intensive tasks such as virtualisation, mail services, office collaboration, and surveillance. With 4K random reads of up to 234,698 IOPS and sequential reads of up to 6258 MB/s, it ensures fast and efficient performance.
Equipped with a powerful 2.1 GHz Intel Xeon D-1541 Eight-Core processor, the RackStation RS4021xs+ enables multitasking capabilities. The built-in 16GB DDR4 ECC RAM ensures quick access to frequently used files and programs, and it can be upgraded to a total of 64GB. The NAS also offers two USB 3.2 Gen 1 Type-A ports for connecting external peripherals. Network connectivity is achieved through two 10 Gigabit Ethernet or four Gigabit Ethernet ports with failover support, ensuring high availability. The NAS supports link aggregation for increased connection speeds beyond the limits of a single network port or cable. Additionally, two PCIe Gen 3.0 x8/x8 slots are available for network interface cards and M.2 NVMe adapter cards for SSD caching.
Running on the user-friendly DiskStation Manager (DSM) operating system, the RS4021xs+ simplifies NAS management, data access, and sharing. It supports various RAID modes such as RAID 0, 1, 5, 6, 10, Basic, and Synology RAID F1, providing users with options for data redundancy, speed, or a combination of both. JBOD is also available for those who do not require a RAID setup.
Synology has prioritized energy efficiency in the design of the RackStation RS4021xs+. It features three 80 x 80mm fans to keep the system cool and supports scheduled power on/off cycles and hard drive hibernation to minimize power consumption and operation expenses. The NAS operates on 100-240 VAC at 50/60 Hz and comes with a limited 5-year hardware warranty for added protection.
