QNAP TS-531X-8G-US overview

  • 1Description

The QNAP TS-531X NAS Enclosure lets you create a personalized network storage solution by featuring the QTS operating system and five bays that can accommodate optional 2.5"/3.5" hard drives and SSDs. To access data quickly, SSD cache acceleration is supported, so you can combine the best of both worlds with SDDs and HDDs. Once drives are installed, the data is quickly delivered to connected systems by utilizing its two Gigabit Ethernet ports and two 10GbE SFP+ ports. Furthermore, a PCIe 2.0 x2 slot lets you add an additional 10 Gigabit SFP+ port or two Gigabit Ethernet ports to this enclosure.

The TS-531X is powered by a 1.4 GHz ARM Cortex-A15 quad-core processor and 8GB of DDR3 memory to run the QTS 4.2 operating system, which manages RAID configurations, storage pools, VPNs, and more. You can quickly extract or load data to the TS-531X using its three USB 3.0 ports along with a USB One-touch-backup button. To cool the components, a single 120mm fan is on board. For safeguarding sensitive files, this enclosure encrypts data with a hardware-accelerated encryption engine. Aside from data protection, it supports SMB/CIFS, NFS, and AFP protocols for file sharing across Windows, Mac, and Linux/UNIX networks. In addition, you can meet future data needs by cascading optional QNAP RAID expansion enclosures to the TS-531X NAS enclosure.

Performance with Hardware-Accelerated Encryption
The TS-531X is equipped with a quad-core 1.4 GHz ARM Cortex-A15 processor and 8GB of DDR3 RAM as well as SATA 6 Gb/s interfaces, two 10GbE SFP+ LAN ports, and two Gigabit LAN ports. An PCIe expansion slot is on board for an additional Network Interface Card (NIC). The TS-531X's hardware-accelerated encryption engine safeguards your sensitive business data with AES 256-bit full NAS volume encryption, boosting system performance and security.
10GbE and Gigabit Ethernet
Two inbuilt Gigabit Ethernet ports and two 10GbE SFP+ ports provide fast throughputs for businesses that demand higher bandwidth for virtualization and fast backup/restoration for an ever-growing amount of data. A PCIe slot allows for the installation of a third 10GbE port for flexible high-speed network deployment. Coupled with its large storage capacity potential, the 10GbE-ready TS-531X is suitable for companies that store massive amounts of data and require fast data transmission.
SSD Cache Acceleration
The enclosure supports SSD caching that can boost IOPS performance of storage volumes to increase operational efficiency. It is suitable for improving the overall workflow of IOPS-demanding applications and provides optimal cost and performance by combining SSDs with HDDs.
QNAP VJBOD (Virtual JBOD) is a network-based JBOD, allowing you to expand the storage of a QNAP NAS with multiple QNAP NAS units. The TS-531X lets you economically expand its capacities with other QNAP NAS storage using VJBOD as well as create virtual storage pools and volumes on the virtual disks for operating NAS services.

Simply search "IoT" in Container Station, acquire proper containers, and create your diverse IoT applications.
QmailAgent is an online email client that helps you manage multiple email accounts, allowing you to access all of your emails and easily switch between different accounts. It provides complete functionality for composing, reading, and organizing emails. You can even attach files, photos, and documents when composing emails. iOS and Android users can use the QmailClient app to quickly check multiple email accounts on mobile devices. You can use QmailAgent together with Qsirch, which supports searching through the .eml files stored on the TS-531X, to make searching through and managing massive amounts of emails easier.
Qcontactz helps you centrally store and manage contact information for colleagues, business partners, families, and friends. Other features include: importing/exporting CSV or vCARD 3.0 files, automatic identification of frequently-used contacts, encryption for sensitive/confidential contact information, smart search function, and more. Qcontactz offers snapshot backups that enable you to revert to a previous version of your contacts list according to your needs. A companion app for Android phones and iPhone is also available for easy access to contacts. Qcontactz can also be used with QmailAgent to create an efficient email workflow environment.
Notes Station 3
The revamped Notes Station features an optimized interface for a smoother user experience. Notes Station allows users to collectively write documents and helps users to track changes by keeping the revision history of documents. Notes Station provides useful image-editing tools, helping you create well-designed documents. You can also create links to share documents in real time. Documents can be encrypted to prevent unauthorized access, and snapshot backup is provided to retain different versions of documents edited at different time periods. With its importing/exporting and full-site backup functions, Notes Station supports backing up your documents to local or remote QNAP NAS.
QTS Operating System
With an intuitive user interface, your NAS experience is smarter and smoother. Its modern flat design streamlines loading times, and the intelligent desktop allows you to find desired functions quickly, create desktop shortcuts or group shortcuts, monitor important system information on a real-time basis, and open multiple application windows to run multiple tasks concurrently, bringing working efficiency. QTS supports nearly all devices, platforms, and various locations to bring optimized cloud experiences to you.
Centralized Data Storage
This NAS enclosure supports SMB/CIFS, NFS, and AFP protocols for file sharing across Windows, Mac, Linux/UNIX networks. Data, logs, and ISO images of CDs and DVDs can be centrally stored on the TS-531X and protected by an integrated antivirus solution. The Windows AD and LDAP services enable system administrators to configure user permissions by using an existing Windows AD server, LDAP server, or built-in LDAP service. It supports SAMBA v4 and can act as a Windows domain controller, which manages privilege settings.
Hybrid Backup Sync
Hybrid Backup Sync consolidates backup, restoration, and synchronization functions into a single QTS app (via RTRR, rsync, FTP, and CIFS/SMB protocols) and provides comprehensive data backup and disaster recovery solutions by easily transferring data to local/remote QNAP NAS, remote servers, and to cloud storage spaces. You can synchronize files between the TS-531X and cloud storage in real time. Hybrid Backup Sync supports multi-version backup, flexible job scheduling, file compression, and more.
Comprehensive Security Options
In open network environments, business data may be exposed in a potential hack. The TS-531X provides numerous security options such as encrypted access, IP blocking, 2-step verification, and more. IT administrators can also control the access rights of each user to different folders, preventing unauthorized access to important files. The TS-531X supports AES 256-bit encryption, preventing sensitive business data from unauthorized access and breach even if the hard drives or the entire system were stolen.
VPN Server & VPN Client
The TS-531X can be used as a VPN server with L2TP/IPsec, OpenVPN, and PPTP support, allowing you to securely access data shared within the private local network. It can also be used as a VPN Client to connect to other VPN servers (connecting multiple servers at the same time is possible) or virtual private network through for PPTP and OpenVPN for secure data transmission. You can connect your devices to your NAS and the VPN server at home to access data on the LAN via a VPN Client on your NAS.
The TS-531X supports Qsirch, a proprietary search engine for quick file searching. In addition to previewing files with thumbnails, content abstract, and keyword hints, Qsirch allows you to search through .eml files stored on the TS-531X and to use customized search criteria such as date, size, sender, and recipient. Qsirch even remembers your search history allowing you to quickly navigate to files you've previously searched for. The Qsirch Helper extension for Google Chrome and Mozilla Firefox can also be used to search for files on your NAS when using Google Search.
File Synchronization
Qsync utility turns your TS-531X into a safe, high-capacity data center for file synchronization. Any file uploaded to the TS-531X will be made available for all linked devices such as computers, laptops, or mobile devices. Qsync is useful for frequent travelers to manage files and always have the most up-to-date files on different devices. Qsync provides multiple ways for file synchronization and group file sharing, enhancing the flexibility of team projects and collaboration.
