Dual-port 2.5GbE and single-port 10GbE connectivity. The dual 2.5GbE ports also support SMB Multichannel for up to 5 Gbps! - Flexible PCIe Gen3 expansion
Features two PCIe Gen 3 slots for installing 5/10/25GbE network cards, QM2 cards or Fiber Channel cards. - M.2 SSD caching
Dual M.2 PCIe NVMe slots enable SSD caching, SSD storage pools, or Qtier auto-tiered storage. - Virtual machines and containers
Host virtual machines and containerized apps on one device to optimize resource utilization and IT budgeting. Supports SR-IOV. - All-inclusive data backup and restoration
A reliable backup center for your PC/Macs, virtual machines, containers, cloud data, and SaaS data. - Ultimate 8-core performance with up to 128 GB RAM and Intel QuickAssist technology
The TS-855X delivers exceptional 8-core performance for running multiple concurrent tasks. AES-NI encryption and Intel QuickAssist technology (QAT) are supported to offload resource-demanding compression and improving IPsec/SSL cryptography performance. - Direct 2.5GbE connectivity for up to ten PC/workstations
Your team needs a high-speed environment and productivity boost, and the TS-855X delivers with two 2.5GbE ports. By installing two 4-port PCIe network cards, the TS-855X can directly connect to up to ten PC/workstations - no switch required - for faster large file transfer/backup, video editing, and much more. - Multi-version snapshots mitigate ransomware threats
The TS-855X supports block-based snapshots that record the state of the system at any time. It helps protect data, which can be restored back to a specific point of time, greatly helping in mitigating the threat of ransomware. - Reliable, high-performance storage for virtualization
The TS-855X supports block-based iSCSI LUN as a reliable, high-performance, and affordable storage solution for mainstream virtualization environments. It supports VMware VAAI and Microsoft ODX to increase performance by offloading server loading for ESXi server and Hyper-V respectively. - All-in-one solution for hosting virtual machines and containers
By running multiple virtual machines and containers on the TS-855X, you can deploy multi-tenant environments and applications to increase management efficiency and save hardware costs. Coupled with the Network & Virtual Switch app that boosts interoperability between virtual machines, containers, QNAP NAS, and other physical devices on the network, you can flexibly allocate physical and virtual network resources to simplify network deployment. - Comprehensive security and privilege settings
The TS-855X is loaded with flexible privilege settings and security measures. Besides IP blocking, QNAP Authenticator, HTTPS connection, there are more apps that help ensure optimal NAS protection against threats like malware and hackers.
