Synology DX517 Specification

The Synology DX517 is a scalable expansion unit designed to seamlessly integrate with select Synology DiskStation NAS models, providing an efficient solution for increasing storage capacity. It features a robust design, housing up to five additional 3.5-inch or 2.5-inch SATA drives, supporting both HDDs and SSDs. This flexibility allows users to choose the right balance between performance and storage needs. The DX517 connects to the main NAS unit via an eSATA cable, ensuring a high-speed data transfer rate to maintain performance consistency across the expanded storage.

Equipped with hot-swappable drive bays, the DX517 allows for easy installation and replacement of drives without needing to power down the system. This feature ensures minimal downtime and enhances the overall user convenience. The unit supports Synology Hybrid RAID (SHR), allowing for efficient disk space management while ensuring data redundancy and protection.

Designed with energy efficiency in mind, the DX517 includes a power recovery feature that automatically powers on or off in sync with the connected DiskStation. This capability helps reduce power consumption and lowers operational costs. Additionally, its quiet cooling system ensures optimal performance with minimal noise, making it suitable for both home and office environments.

The DX517's compatibility is primarily with Synology's DSM (DiskStation Manager) software, which provides a user-friendly interface for managing the expanded storage. Users can easily configure and monitor their storage through DSM, taking advantage of features such as automated backups, file sharing, and comprehensive security options. Overall, the Synology DX517 is a versatile and reliable expansion solution for those seeking to extend their NAS storage capabilities efficiently.

Synology DX517 F.A.Q.

How do I expand storage capacity using Synology DX517?

To expand the storage capacity using Synology DX517, connect the expansion unit to your Synology NAS via the provided eSATA cable. Once connected, the NAS will recognize the additional drives, and you can manage them through the Storage Manager in DSM.

What should I do if my Synology DX517 is not recognized by the NAS?

Ensure that the eSATA cable is securely connected both to the DX517 and the NAS. Check the power supply and make sure the expansion unit is powered on. If the issue persists, try restarting both the NAS and the DX517.

Can I mix different hard drive sizes in the Synology DX517?

Yes, you can mix different hard drive sizes in the DX517. However, for optimal performance and storage efficiency, it is recommended to use drives of the same size and type.

How can I ensure data protection in my Synology DX517 setup?

You can ensure data protection by configuring RAID on your Synology NAS, using compatible drives in the DX517. Regularly back up your data and consider enabling features like Snapshot Replication if supported by your NAS model.

Is it possible to hot-swap drives in the Synology DX517?

Yes, the Synology DX517 supports hot-swapping of drives. However, ensure that the drive is not in use and that you have a redundant RAID setup to prevent data loss during the swap.

What maintenance is required for the Synology DX517?

Regular maintenance for the DX517 includes cleaning dust from the unit and checking the health of the drives using DSM's Storage Manager. Ensure firmware is up to date and inspect cables for any signs of wear.

How do I update the firmware of the Synology DX517?

The DX517 itself does not have firmware to update. Instead, ensure your Synology NAS has the latest DSM version, as it manages the expansion unit's functionalities.

Can I use SSDs in the Synology DX517?

Yes, SSDs can be used in the DX517. They can provide faster access speeds but ensure they are compatible and that your storage plan takes advantage of their performance benefits.

What is the maximum number of drives supported by Synology DX517?

The Synology DX517 supports up to five drives. You can use this in conjunction with your existing NAS drives to expand your total storage capacity.

How do I troubleshoot a drive failure in the Synology DX517?

If a drive fails, DSM will notify you. You can identify the failed drive through the Storage Manager. Once identified, replace the drive with a new one of equal or larger size and allow the RAID to rebuild.
