- Designed for heavy business workloads, the TS-855eU-RP delivers exceptional 8-core performance for running multiple concurrent tasks. AES-NI encryption and Intel QuickAssist Technology (QAT) is supported to offload computationally-intensive compression and improving IPsec/SSL cryptography performance. Up to 64 GB ECC RAM is supported and redundant power supplies are included to ensure 24/7 system stability. Combining high performance, reliability, and capacity, the TS-855eU-RP is an all-round budget-friendly storage solution for diverse applications, such as file servers, high-speed storage/backup/recovery, and virtualization.
- Affordable 2.5GbE meets high-bandwidth demands
- With two 2.5GbE RJ45 LAN ports (backwards compatible with 1G/100M), the TS-855eU-RP allows businesses to easily upgrade network speeds from 1 Gigabit to 2.5 Gigabit using existing CAT5e cables. Port Trunking and failover also reinforce applications demanding higher bandwidth and reliability, including virtualization, large file transfers, high-speed backup/restoration, and real-time applications. QNAP also offers numerous managed/unmanaged 2.5GbE/10GbE switches, assisting organizations in implementing high-speed, secure, and scalable network environments without going over budget.
- M.2 PCIe slots for SSD caching and accelerated AI-powered image recognition
- The TS-855eU-RP comes with two M.2 PCIe Gen 3 slots that allow for installing M.2 2280 NVMe SSDs or Edge TPU (sold separately) to boost NAS performance.
