Qnap: QTS 4.5.2 NAS OS With Enhancing SNMP, Adding Support for SR-IOV and Intel QAT

Qnap Systems, Inc. released QTS 4.5.2, the latest version of advanced NAS OS.

Key features of QTS 4.5.2 include enhancement of SNMP for network device monitoring and support for Single Root I/O Virtualization (SR-IOV) and Intel QuickAssist Technology (Intel QAT) passthrough to VMs. The company has also debuted its high-speed 100GbE network expansion card. With enhancements to virtualization, networking, and management functionalities, the firm’s NAS can assist businesses and organizations realize performance potential for meeting current and emerging IT challenges.

Key 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
  It 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 100Gb/s 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.

QTS 4.5.2 is available from the Download Center.
