The QNAP TS-855EU-RP is a 2U rackmount NAS designed for Small and Medium Businesses, offering robust data storage and management. Its key benefit lies in its expandable 8-bay capacity and the advanced QuTS hero operating system, providing enterprise-grade features like ZFS. A potential caveat is the requirement for users to purchase and install their own storage drives.

Yes, the QNAP TS-855EU-RP is an enclosure and does not come with storage drives installed. You will need to purchase and install your own 2.5" or 3.5" SATA HDDs or SSDs.
QuTS hero is QNAP's advanced NAS operating system based on ZFS. It offers features like inline data deduplication and compression, real-time snapshots, and advanced data integrity protection, making it suitable for demanding business applications.
The TS-855EU-RP comes with 8GB of DDR4 RAM and has two SO-DIMM slots, allowing for expansion up to a maximum of 64GB.
Yes, the drive bays support both 2.5" and 3.5" SATA drives, including HDDs and SSDs. You can mix drive sizes and types within the same NAS, though it's recommended for performance to use similar drives within a RAID array.
Redundant power supplies provide high availability. If one power supply unit fails, the other takes over, ensuring the NAS continues to operate without interruption, thus minimizing downtime.
Yes, the TS-855EU-RP supports Wake-on-LAN (WOL), allowing you to remotely power on the NAS from a powered-off state over the network.
You can update the QuTS hero operating system through the NAS web interface. Navigate to the Control Panel or System Settings and look for the Update or Firmware Update option. It's recommended to back up your data before performing major updates.
Verify that both power supply units are securely connected to the NAS and a working power outlet. Check if the power indicator light is on. If not, try a different power cable or outlet.
Ensure the NAS is connected to the network and has obtained an IP address. Use QNAP's Qfinder Pro utility to locate the NAS on the network. Check your firewall settings to ensure it's not blocking access.
Confirm that your network infrastructure (switches, cables) supports 2.5GbE speeds. Check NAS network settings and ensure jumbo frames are configured appropriately on both the NAS and the switch. Monitor resource usage on the NAS (CPU, RAM, disk I/O).
Ensure the drive is properly seated in the bay. Check the drive's health status in the Storage Manager. If the drive is new, it may need to be initialized. If a drive is failing, back up data immediately and replace it.
Check the health of all drives in the RAID array. Ensure there are no other failing drives. Consult the QuTS hero documentation for specific RAID error codes and advanced troubleshooting steps. Contact QNAP support if issues persist.
