5 GbE network expansion card

The 5 GbE network expansion card delivers speeds of up to 5 Gbps. You can easily upgrade the transfer speed in your network environment with existing cables.

Use two 2.5-inch SATA drives in a single 3.5-inch SATA drive bay with RAID support for PC and NAS

The QDA-A2AR can accommodate two 2.5-inch SATA drives within a single 3.5-inch SATA drive bay. No software driver is required for the QDA-A2AR, and it can be installed in a PC/workstation (Windows®, Linux®) or QNAP NAS to flexibly add additional hard drives or SSDs to meet various storage needs.

Use two 2.5-inch SATA HDDs/SSDs (7mm to 9.5mm high) in a single 3.5-inch drive bay. (HDD/SSD sold separately)

Up to 6 Gb/s file transfer speeds. Can be the primary bootable device for PCs.

Choose a hardware RAID group with the disk mode switch.

Supports various RAID levels

The QDA-A2AR supports a variety of RAID configurations. Depending on your requirements, you can use the bundled metal pin as disk mode switch tool to select your ideal RAID mode: Individual, JBOD, RAID 0, or RAID 1. Windows® users can use the QNAP External RAID Manager utility to view the RAID group status and disk health information.

A PC that supports SATA port multipliers can connect two SATA drives to a single SATA port, allowing you to independently access each disk as separate storage space.

Half of the total storage capacity is used to store data, and the other half keeps a copy of this data. This provides high data protection at the cost of only being able to use half the installed storage space.

Data is split amongst the drives. RAID 0 provides the fastest performance but does not protect data from drive failure.

All the drives are recognized as a single drive. This allows maximal storage utilization but provides no data protection.

Install in a PC/workstation for higher performance or data protection

When using two 2.5-inch drives instead of a single 3.5-inch drive in a PC/workstation (Windows® or Linux®) you can create a RAID 0 for enhanced performance, or RAID 1 to add data redundancy for greater data protection. To deal with tasks that require intensive, fast data transmission, you can install high-speed SATA SSDs to achieve maximized performance and lower latency, ideal for on-the-fly video editing and server-grade applications.

External RAID Manager for Windows users

The QNAP External RAID Manager utility allows Windows® users to view the drive status and RAID information of the QDA-A2AR. Firmware updates for the QDA-A2AR can also be managed with the External RAID Manager utility.

Install in QNAP NAS for efficient storage or SSD caching

The QDA-A2AR supports hardware RAID that will not consume CPU resources to help sustain optimal NAS performance. You can install one or more QDA-A2AR in a NAS to maximize the storage utilization of 3.5-inch drive bays. The QDA-A2AR can accommodate two SSDs to create an SSD volume for performance-demanding workflows or work in an efficient tiered-storage environment with Qtier. It can also boost IOPS performance when configuring SSD caching. RAID information and drive health of the QDA-A2AR can be monitored through the QTS Storage & Snapshots Manager.

QNAP's QGD-1600P is the world's first PoE managed switch that supports Virtual Machines (VMs). It features 4-port 60-watt and 12-port 30-watt Gigabit PoE (with two PoE/SFP Combo ports) for highly flexible networking environment deployment. With a dual-CPU design, the QGD-1600P provides both Layer 2 management functions for VM and QTS applications. The QGD-1600P also features Software-Defined Networking (SDN), enabling it to function as a NAS, NVR, router, firewall and AP controller for IP surveillance, network security, storage expansion, and wireless LAN management applications. Therefore, the Guardian series offers SMBs a cost-optimized and centrally managed LAN deployment solution.

QGD-1600P is compliant with the latest IEEE 802.3bt PoE++ and IEEE 802.3at PoE+ standards, and offers 4-port 60-watt and 12-port 30-watt Gigabit PoE capability. QGD-1600P can supply a total power budget of 370 watts to meet the demands of high-powered devices (PDs).

QGD-1600P provides comprehensive Layer 2 management features, such as VLAN, LACP, QoS IGMP Snooping, and Wake-on-LAN for IT administrators to efficiently control the network bandwidth and enhance security via the user-friendly switch management web interface.

QuNetSwitch offers a user-friendly web interface to help IT administrators efficiently control Layer 2 and PoE networks. Additionally, the overview dashboard and graphical statistics analysis show IT administrators all switch information and pored devices at a glance, making central management of high-power devices intuitive and easy.

Supports up to two SATA drives.

PCIe expandability allows for 10GbE network cards, QM2 dual-port M.2 SSD/10GbE cards, USB 3.1 Gen 2 (10Gbps) cards, or Wireless Adapters.

Host containerized applications and virtual machines with various operating systems. Flexibly install virtual router, firewall, or wireless LAN management software for various networking management applications.
