QNAP has also debuted its ultra-high-speed 100GbE network expansion card. With comprehensive enhancements to virtualization, networking, and management functionalities, QNAP NAS can assist businesses and organizations realize the highest performance potential for meeting current and emerging IT challenges.

Key new features in QTS 4.5.2

  • SR-IOV network virtualization
    By installing an SR-IOV compatible PCIe SmartNIC in a NAS, bandwidth resources from a physical network card can be allocated directly to VMs. With traffic bypassing the Hypervisor vSwitch, it helps enhance I/O throughout and network efficiency by 20%, ensuring reliable VM applications and reduced CPU overheads.
  • Intel® QAT hardware accelerator
    Intel® QAT provides hardware acceleration that offloads computationally intensive compression, improves IPSec/SSL cryptography performance, and supports SR-IOV for improved I/O throughput. All can be passed through to VMs on the NAS for optimized performance.

QXG-100G2SF-E810 dual-port 100GbE network expansion card (Available soon)

The QXG-100G2SF-E810 uses the Intel® Ethernet Controller E810, supports PCIe 4.0, and provides up to 100Gbps bandwidth to overcome performance bottlenecks. It supports Windows® and Linux® servers/workstations, allowing users to attain optimal business performance for a wider range of system applications and services. The higher bandwidth density with reduction in links help reduce cabling footprint and operational costs.
