Synology DS1621+: 24TB NAS Server with NVMe Storage & Gigabit Ethernet

The Synology DiskStation DS1621+ is a high-performance NAS (Network Attached Storage) server designed for a wide range of server roles, including iSCSI target backup, large file storage, email server hosting, and domain controller management. Built with a Ryzen V1500B quad-core 2.2GHz CPU and 32GB DDR4 ECC SODIMM memory, this device provides robust processing power and reliability for environments with intensive multi-user workloads. It is ideally suited for small and medium-sized businesses requiring scalable storage solutions that can grow alongside their needs.

The DS1621+ features an extensive storage configuration consisting of 24TB of SATA 2.5" SSDs, composed of six 4TB drives, offering high-speed access to large data sets. In addition to the primary storage array, the system includes two M.2 solid-state drives totaling 1TB capacity, arranged as two 500GB units. These M.2 drives serve as a cache for ultra-fast read and write operations, significantly enhancing performance for applications that demand quick data access.

For network connectivity, the DS1621+ is equipped with four RJ-45 1GbE LAN ports that support link aggregation and failover capabilities to ensure reliable and redundant network connections. The device also includes three USB 3.2 ports and two eSATA ports for additional external storage or peripheral connectivity options.

The Synology DiskStation DS1621+ runs on the Synology DSM operating system, which offers an extensive suite of applications tailored for enterprise-level functionality. These include iSCSI target protocol support for block-level storage access, virtual machine management through the Virtual Machine Manager tool, and Synology High Availability to maintain service continuity in mission-critical environments. Additional features such as Synology MailPlus enable the setup of email servers while Security Advisor ensures compliance with security standards through advanced threat detection mechanisms.

Data protection is reinforced with AES 256-bit encryption across all stored data and support for two-factor authentication to prevent unauthorized access. The system also includes Cloud Station Suite for seamless cloud integration, Active Backup solutions for VMware and Windows environments as well as Office 365 and G Suite backups, Surveillance Station role for managing large-scale video surveillance deployments, Collaboration Suite tools to enhance team productivity, and Synology Drive to enable centralized file sharing across devices.

The internal file system uses EXT4 along with Btrfs formats that support advanced LUN (Logical Unit Number) services essential for iSCSI applications. The use of Btrfs also contributes to enhanced data integrity through features like checksumming and snapshotting.

This NAS device comes in a sealed box with all components included separately—hard drives and memory are not pre-installed but are available as upgrades that require installation by the user. It operates on a single power supply unit and is optimized for tasks such as virtual machine hosting, containerized workloads, high-quality video editing due to its substantial processing power and fast disk access speeds.

In conclusion, the Synology DiskStation DS1621+ represents a versatile solution tailored to meet the diverse demands of modern business environments through its powerful hardware specifications combined with comprehensive software capabilities. Whether deployed as a central storage hub or an integrated part of an enterprise infrastructure setup involving virtualization or multimedia processing workflows—the DS1621+ delivers exceptional performance along with flexibility necessary to adapt efficiently according to evolving technological requirements within any organization's IT framework.
