Synology DS1821+ Specification

The Synology DS1821+ is a high-performance NAS designed for data-intensive tasks and business environments. This 8-bay network-attached storage device is powered by an AMD Ryzen V1500B quad-core processor with a base frequency of 2.2 GHz, providing robust computational power for multitasking and efficient data processing. Equipped with 4 GB of DDR4 ECC memory, expandable up to 32 GB, it ensures data integrity and system reliability even under heavy workloads.

The DS1821+ supports a maximum raw capacity of 108 TB with its eight drive bays, which are compatible with both 3.5" and 2.5" SATA HDDs and SSDs, enabling flexible storage configurations. Dual M.2 2280 NVMe SSD slots are available for cache acceleration, significantly boosting access speeds and system responsiveness. For network connectivity, the NAS features four Gigabit Ethernet ports with Link Aggregation and Failover support, enabling high-speed data transfers and network redundancy.

This model is compatible with Synology's DiskStation Manager (DSM) operating system, offering a comprehensive suite of applications for backup, file sharing, virtualization, and collaboration. Advanced features such as Btrfs file system support, snapshot replication, and robust data protection mechanisms are integral to its design, ensuring data security and reliability. Additional scalability is provided through the optional DX517 expansion unit, allowing users to increase the storage capacity as their data needs grow.

The DS1821+ is engineered for energy efficiency with a power consumption of 36.67W during access and 16.71W during hibernation, making it a cost-effective solution for businesses seeking to balance performance and operational expenses. Its compact design, measuring 166 mm x 343 mm x 243 mm, fits easily into various office environments while delivering enterprise-grade features and performance.

Synology DS1821+ F.A.Q.

How do I set up my Synology DS1821+ for the first time?

Begin by installing the hard drives in the bays. Connect the DS1821+ to your network using an Ethernet cable and power it on. Use a computer to access the Synology Assistant software to find your device and initiate the DSM installation process. Follow the on-screen instructions to complete the setup.

What should I do if my DS1821+ is not showing up on the network?

Ensure that the Ethernet cable is properly connected to both the NAS and the router. Try using a different cable or port. Check that the NAS is powered on. If the issue persists, use Synology Assistant to locate the NAS. Consider resetting the network settings if necessary.

How can I expand the storage capacity of my DS1821+?

You can expand storage by adding more hard drives to the available bays or replacing existing drives with higher-capacity ones. After installing the new drives, use DSM to manage and expand your storage pool and volume.

What is the procedure for performing a system backup on the DS1821+?

Utilize Hyper Backup, Synology’s backup solution, to create backup tasks. Choose the data you want to back up, select a backup destination, and configure a schedule. Regularly verify and test your backups for integrity.

How do I troubleshoot if my DS1821+ is not powering on?

Check the power cable and ensure it is securely connected. Test the outlet with another device to confirm it is working. Try a different power cable if available. If the NAS still does not power on, consider contacting Synology support for further assistance.

How can I optimize the performance of my DS1821+?

Ensure DSM is up to date. Enable SSD caching if SSDs are available. Optimize network settings by using Link Aggregation if supported by your network infrastructure. Regularly monitor and manage workloads to prevent resource bottlenecks.

What actions should be taken if my DS1821+ experiences a hard drive failure?

Replace the failed hard drive with a compatible new one. Use DSM to repair the storage pool. Ensure regular monitoring of the system's health status and configure alerts for prompt notifications.

How do I set up remote access to my DS1821+?

Utilize Synology’s QuickConnect feature to access your NAS remotely. Alternatively, configure port forwarding on your router and use DDNS for a consistent external IP address. Ensure security settings are correctly configured to protect against unauthorized access.

What maintenance tasks should I perform regularly on my DS1821+?

Regularly update DSM and package software. Check the health status of hard drives. Clean dust from the unit to prevent overheating. Verify the integrity of backup data and review system logs for any unusual activity.

How can I improve the security of my DS1821+?

Enable firewall and security features within DSM. Use strong, unique passwords and enable two-factor authentication. Regularly update DSM and all installed packages. Limit user permissions to only those necessary and monitor access logs.
