Function Designed for flexible deployment in IT environments and complex virtualization applications, the TS-855eU NAS with a small depth and 2.5GbE interface can easily fit into a compact rack in an office or audiovisual studio. Equipped with an Intel® octa-core processor, it offers superior performance and computing advantages for fast data access, backup/restore, file server operation, and virtualization applications. It comes standard with QTS operating system and can be switched to QuTS hero ZFS operating system based on your requirements. In addition, it will have support from QNAP for an extended period (until 2027), during which the TS-855eU will also be on sale. It is therefore ideal for businesses that need to use identical NAS models during long-term projects.

• NAS TS-855eU-RP with a depth of 297.4mm is ideal for installation in a compact rack or in places with complex cabling.
• It offers two 2.5GbE ports (backwards compatible with 1G/100M). These support port pooling for increased performance and fault tolerance.
• Provides two PCIe Gen 3 slots for installing 5/10/25GbE network cards, QM2 cards or Fiber Channel cards.
• Thanks to two M.2 PCIe NVMe slots, you can use SSD cache, SSD data volumes or automatically tiered Qtier™ storage.
• Centralize your virtualization storage and host multiple VMs and containerized applications.
