QNAP TS-451 Turbo NAS Features

As the volume of personal digital data continue to rise, individuals and families need higher-capacity storage solutions which are secure, reliable, and easy to manage. Most households have several different tiers of data that they need to manage. Financial records need the highest level of redundancy and security. Less critical personal data, like the family recipe archive, and the kid’s homework from last year, can get by with slightly lower redundancy and a whole lot less security controls. The combined family archive of multimedia files, videos and music for the most part probably warrants the lowest priority, as it is the easiest data to replace if it’s lost due to failure of a storage system. I’m not saying that you don’t want to back up your music library, but you may not want to pay a yearly or monthly fee to store it in the cloud.

NAS + iSCSI/IP-SAN Solution for Server Virtualization

The QNAP® TS-451, which serves as both IP-SAN (iSCSI) and NAS, can also be easily utilized in different business and enterprise applications such as backup center, disaster recovery, file sharing, virtualization, and video editing storage. The TS-451 offers class-leading system architecture matched with a wide range of configuration options and native apps. There is precious little that the modern NAS box cannot do, in either the home or business environment. The ability to run an independent virtual machine on the second core of the CPU also brings new capability and performance options to the table.

The Feature-rich and Integrated Applications for Business

The NAS supports file sharing across Windows, Mac, Linux, and UNIX platforms. Versatile business applications such as file server, FTP server, printer server, web server, and Windows AD support are provided. The dominant features, such as WebDAV, Share Folder Aggregation (also known as DFS), IPv6 and IPv4 dual-stack, Wake on LAN, schedule power on/ off, HDD S.M.A.R.T, comprehensive log systems, and policy-based unauthorized IP blocking are all included features of a QNAP NAS server.

Secure – Data might seem insecure being open in a network, but the QNAP® TS-451 offers a variety of security options such as encrypted access, IP filtering, policy-based automatic IP blocking, and more. In addition, full control of the NAS is offered down to the user and folder access rights to determine who can access the NAS and what can or cannot be accessed. The TS-451 is packed with security features to stop all unauthorized data access such as AES-256 volume-based encryption. The AES-256 volume-based encryption prevents sensitive data from unauthorized access and data-breach even if the hard drives or the device is stolen.

Reliable – The TS-451 is reliable with built-in safety precautions to safeguard all data from any unforeseen problems. With multiple built-in features to guarantee no interruptions to the work flow of a business, the TS-451 is an efficient asset. The advanced RAID configurations and hot-swap capabilities are included to give RAID performance, protection and reduced rebuilding time. Moreover, the dual OS embedded on the DOM architecture ensures the system will boot up. If one of the two operating systems fails, the healthy operating system will boot up and operate normally while repairing the failed operating system. The two Gigabit LAN ports can also be configured for failover which allows the NAS server to sustain the failure of one network ports and still provide continuous services.

Simple – Setting up local or remote access with the TS-451 is painless and does not require any IT skills in order to get the basics right. All setup processes have been simplified so that most of the process is either automatic or can be completed by an installation wizard. The user-friendly web GUI allows administrators to easily manage the NAS so there is no need for an extensive knowledge of complex commands. Simple management tools such as instant SMS/Email alert, the hard drive S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) feature, and system resource monitor are provided to keep administrators up-to-date on their NAS at all times.

High Network Bandwidth – The TS-451 does not offer a network expansion option, but it includes dual-port 1 GbE network ports, which can be aggregated to boost network performance.

Blazing Fast Data Backup via USB 3.0 – The TS-451 features USB 3.0 ports for high speed backup to external hard drives. EXT3, EXT4, NTFS, and HFS+ file systems are supported to ensure compatibility with Windows, Mac® OS X, and Linux operating systems.

Cross-platform Sharing with Antivirus – The TS-451 supports SMB/CIFS, NFS, and AFP protocols for file sharing across Windows, Mac, Linux/UNIX networks. User accounts and shared folders can be created via the user-friendly web-based interface without IT expertise. The integrated antivirus solution for the Turbo NAS ensures business continuity by offering detection against the latest viruses, malware, worms, and Trojan horses.

iSCSI for Virtualization Deployments The Turbo NAS provides flexible and secure storage server deployment with the following enhanced iSCSI features:

NAS + iSCSI storage solution The Turbo NAS can serve as a NAS for file sharing and iSCSI storage concurrently.

Flexible multiple LUNs management The NAS supports multiple LUNs (Logical Unit Numbers) and iSCSI targets. The LUNs can be flexibly mapped to, unmapped from, and switched among different iSCSI targets.

Secure IP SAN environment deployment Designed with CHAP authentication and LUN masking, the advanced ACL (Access Control List) offers you the capability to block unauthorized access from the initiators.

Advanced RAID Management with Hot-swap Design The TS-451 NAS offers advanced RAID 0, 1, 5, 6, 10, Single, and JBOD disk configurations. It also supports hot-swap design that a failed drive can be replaced by hot swapping without turning off the server.

Online RAID Capacity Expansion The storage capacity of a RAID configuration can be expanded by replacing the hard drives with larger ones. All the data will be kept and seamlessly moved to the newly installed hard drives. There is no need to turn off the server during the process.

Online RAID Level Migration You can upgrade the disk configuration to higher RAID level with the data retained. There is no need to turn off the server during the process.

Virtual Disk Drive (VDD) adds flexibility to storage expansion along with ease of management The unique “Virtual Disk Drive” adds flexibility to expand the capacity of NAS. By using the built-in iSCSI initiator, the NAS can connect to other iSCSI targets on the network and turn them into virtual disks, which become multiple single volumes on the NAS. The NAS serves as the storage stack chaining master. The user only needs to connect to this single entry (QNAP NAS) and is able to reach and use all the iSCSI target storages on the network.

S.M.A.R.T & Advanced HDD Health Scanning (HHS) The NAS supports Hard Disk Drive S.M.A.R.T (Self-Monitoring Analysis and Reporting Technology) for monitoring the hard drive status. Moreover, the NAS is embedded with HHS Technology which supports disk checking and bad blocks scanning.

UPS Support The NAS supports the majority of USB UPS devices which enables the users to store the data in time and avoid critical data loss when power outage occurs during data transfer.

QNAP Backup Software – NetBak Replicator The backup software, NetBak Replicator, is provided for the NAS users to perform real-time synchronization or schedule backup from multiple PCs to the NAS.

3rd Party Backup Software Ready The NAS works well with other backup software, e.g. Acronis True Image, CA BrightStor ARCserve Backup, EMC Retrospect, Symantec Backup Exec, and LaCie Silverkeeper.

Encrypted Remote Replication The data on the NAS can be backed up to or from another Turbo NAS over the network securely.

Sharing Files across Windows, Mac, Linux, and UNIX The NAS is designed for users to share the files across Windows, Mac, Linux, and UNIX environment.

Windows Active Directory (AD) and LDAP Directory Service The Windows AD and LDAP (Lightweight Directory Access Protocol) directory service features enable the system administrator to retrieve user accounts from Windows AD or Linux LDAP server to the TS-451 reducing time and effort in account setup. Users can use the same login name and password to access the TS-451.

Web File Manager The NAS provides Web File Manager for you to easily download, upload, and manage the files on the server by web browser.

Ease of User and Share Folder Management The NAS supports batch creation of users and share folders to save the time and effort of the server manager in account and folder creation. For the security of Windows network environment, server managers can hide or show network share folders.

Hard Disk Standby You can configure the hard disks to enter standby mode if there is no disk access within the specified period.

Schedule Power on/ off The flexible schedule power on/off feature is now provided on the NAS for IT administrators to manage the NAS server’s up time according to the working hours. You can set the time for automatic system power on, power off, or restart on any days of the week.

Secure data storage, access, and sharing

  • Comprehensive event logs: Detailed logs of file-level data access to the NAS via samba, FTP, AFP, HTTP, HTTPS, Telnet, and SSH, and networking services accessed by online users are all recorded.
  • SSL security (HTTPS): The NAS can be accessed and configured by web browser securely.
  • Remote login to the NAS by SSH (secure shell) or Telnet connection is supported.
  • Secure FTP: The data can be transmitted with SSL/TLS (explicit) encryption. Passive FTP port range setup is also supported.
  • Write-only access right on FTP server: The third party partners are allowed to upload data to the NAS but not able to read or edit the data on FTP server.

Policy-based Automatic IP Blocking To prevent the NAS from malicious attacks, the server manager can create an IP filter policy to allow, deny, or auto-block the IP address or network domain which attempts to connect to the NAS via SSH/ Telnet/ HTTP(S)/ FTP/ samba/ AFP.

The most comprehensive support for numerous brands of IP cameras The Surveillance Station of QNAP NAS supports over 1400 models from all the leading network camera brands such as AXIS, D-Link, IPUX, LevelOne, Linksys, Panasonic and Vivotek etc. Each of the supported cameras has been put through stringent tests with the NAS series in QNAP’s laboratory to guarantee 100% compatibility and reliability with all these camera brands.

    If I’ve read the screenshot of ATTO correcty, you’ve just measured your C drive on SSD 🙂 1Gbit interface is exactly that – 1Gbit = theoretical 125MB/s. With the overhead it will max out on 110-180MB/s which you got in other softwares. I would suggest fixing that part of otherwise great review 😀

    Well, that might explain the very strange results I got….. Thank you so much for pointing that out. I will redo that test and post the true results.

    QNAP suggest 3 possible usb tv tuners for use with this model….namely UPMOST DVB192A HD; Hauppauge Win TV Nova_T Stick (Device: 70019;HW rev DiF4) or Asus My Cinema U3100 Mini. I mistakenly bought a QNAP USB tv Stick when I originally acquired the above unit, thinking that it would naturally be compatible. Some of the above sticks are difficult to either isolate or acquire in UK and I was wondering if anyone else with similar NAS has had any luck with any other usb stick.
