Designed for flexible IT deployment and comprehensive virtualization applications, the short-depth TS-855eU-RP 2.5GbE NAS can easily fit in a compact rack in offices or audiovisual rooms. Powered by an Intel® 8-core processor, the TS-855eU-RP packs excellent performance and computing benefits to empower fast data access, backup/restoration, file server, and virtualization applications, while including redundant power supplies to ensure maximum system uptime. Running the QTS operating system as standard, the TS-855eU-RP can be switched to use the ZFS-based QuTS hero operating system based on your requirements. The TS-855eU-RP will be available and supported by QNAP for an extended period (up to 2030) , ideal for businesses requiring matching NAS models deployed for long-term projects.
The TS-855eU-RP has a depth of only 11.7 inches (297.4 mm) and is perfectly suited for installation in a compact rack, or places with a lot of cabling.
Connect TL-R1620Sep-RP / TL-R1220Sep-RP JBOD units to the TS-855eU-RP for adding up to 48 additional drive capacity to match your business growth.
Features two 2.5GbE ports (backwards compatible with 1G/100M). Supports port trunking for enhanced performance and fault tolerance.
Features two PCIe Gen 3 slots for installing 5/10/25GbE network cards, QM2 cards or Fibre Channel cards.
Dual M.2 PCIe NVMe slots enable SSD caching, SSD storage pools, or Qtier™ auto-tiered storage.
Centralize your virtualization storage, and host multiple virtual machines and containerized apps.
Common Fibre Channel Storage Area Networks (SAN) devices are often costly. By installing QNAP dual-port 16Gb /32Gb Fibre Channel expansion cards in the TS-855eU-RP, you have more budget-friendly options to add a NAS to a SAN environment. You can set a Fibre Channel Target using the iSCSI & Fibre Channel app. Moreover, the LUN Masking and Port Binding features provide an additional layer of data security.
