8. 2x 10GbE SFP+ ports

Dual 10GbE connectivity optimizes high-speed data transfer and VMware virtualization with iSER

The TS-883XU provides two 10GbE SFP+ ports that use the Mellanox® ConnectX®-4 Lx SmartNIC controller. They support the iSCSI Extensions for RDMA (iSER) protocol, allowing data to bypass general network drivers, the socket layer, and to directly enter memory buffers of the ESXi server and storage to offload CPU workloads. When both the VMware® server and the TS-883XU support iSER, it can provide up to 60% increased random read/write performance and 50% decreased latency, providing an essential tool to optimize demanding virtualization applications.

Recommended usage of PCIe slots

The TS-883XU provides multiple PCIe slots. To ensure that the SATA drives have sufficient bandwidth, it is recommended to only use low-end expansion cards, (such as a 1GbE NIC, USB 3.0 card, or Wi-Fi adapter) with the PCIe Gen2 slot (Slot 1) as this slot is connected to the PCH. For high-end expansion cards (including 10GbE/40GbE NICs, SAS cards, Mustang-200 acceleration card, and graphics cards), it is recommended to use PCIe Gen3 slots (Slot 2, 3, 4) as these slots are connected to the CPU.

Empower GPU-accelerated computing with graphics cards

Graphics cards are optimized for graphical calculations and transformations. The TS-883XU provides PCIe slots for installing an AMD Radeon™ or NVIDIA® graphics card to boost data-intensive AI machine learning, while also providing benefits for imaging processing and virtual machine performance (via GPU passthrough).

Note:
1. 3U/4U models support high-profile graphics cards that require external power; 1U/2U models support low-profile graphics cards that do not require additional external power (For example, the NVIDIA GT1030).
2. GPU support for QTS only applies to NVIDIA graphics cards. GPU Passthrough for VM is supported by AMD and NVIDIA graphics cards.
3. When Virtualization Station uses graphics cards, the NAS will temporarily stop hardware transcoding acceleration for QTS (and vice versa).
4. Always consult the Compatibility List for supported NAS and graphics cards before purchasing a graphics card for the NAS.

SSD caching and auto tiering enable 24/7 optimized storage efficiency

By enabling Qtier™ auto-tiering on the TS-883XU, organizations can just buy the amount of SSDs needed, and attain the highest value/performance and optimal storage efficiency for data storage and sharing.

Improve random data access speeds with an SSD cache
SSD caches accelerate IOPS performance and reduce latency for storage volumes. They are perfect for IOPS-demanding applications (including databases and virtualization) and can significantly improve overall workflows. The TS-883XU also supports write-only SSD caches to greatly boost write-intensive applications and also RAID 5/6 SSD caches for higher performance and caching space.

Maximize the value of SSDs with Qtier Technology
Qtier™ Technology empowers the TS-883XU with auto tiering that helps continuously optimize storage efficiency by automatically moving data between 2.5-inch SSDs and high-capacity HDDs based on the data's access frequency. Qtier™ 2.0 features IO-awareness that empowers SSD-tiered storage with a cache-like reserved space to handle burst I/O in real time, greatly maximizing the advantages of SSDs.

Up to 128 monitoring channels in QVR Pro for well-rounded security surveillance

The TS-883XU supports QVR Pro surveillance solution with 8 license-free channels for surveillance monitoring, which can be expanded up to 128 channels* with additional channel license purchase for a more extensive security deployment. QVR Pro supports over 5,000 IP cameras, including all of the standard fisheye cameras available on the market. There are more advanced features for fully unleashing the potential of fisheye cameras: allowing a single fisheye camera’s image to be simultaneously viewed in nine channels from different angles, and cross-platform hardware-accelerated decoding for fisheye camera images. QVR Pro ensures higher surveillance performance for greater security while providing deployment flexibility and budget-savings.

Flexibly allocate physical and virtual network resources to simplify network deployment

The Network & Virtual Switch application allows you to leverage limited physical network resources for unlimited virtual applications and centrally manage the entire network structure with a brilliantly-visualized network topology map. Flexible manageability enables you to reorganize physical and virtual network connections with greater ease, so you can allocate adequate network resources to the TS-883XU, virtual machines and containers whenever needed. The network deployment is greatly simplified while your network management efficiency is greatly improved.
