QNAP TS-419U/4TB User Manual

QNAP TS-419U Turbo NAS is the 4-bay, 1U chassis multi-functional network attached 
storage (NAS) server designed for small and mid-sized business who is looking an 
affordable and low-powered network storage solution. The TS-419U can be easily installed 
and maintained in the server room. It is an ideal solution for mass data backup, 
management and sharing. Moreover, the NAS supports excellent hardware design, 
outstanding performance, high system reliability and expandability, and numerous powerful 
software applications. It is undeniably the top-notch model in the 4-bay 1U chassis NAS 
market.

The TS-419U adopts Marvell 1.2GHz CPU and 512MB DDRII memory. It supports 4 
2.5-inch and 3.5-inch hot-swappable SATA hard drives, 2 Gigabit LAN ports for multi-IP 
settings and port trunking (7 bonding modes) modes. The NAS is equipped with 4 USB 
ports and 2 eSATA ports for storage expansion or external data backup.

The TS-419U supports RAID 0/ 1/ 5/ 6/ 5+spare, single and JBOD disk configurations. The 
unique Online RAID Capacity Expansion and Online RAID Level Migration allow the users 
to expand the storage capacity of the RAID configuration and upgrade the RAID level 

without turning off the server respectively. The RAID recovery feature secures the server 
data against accidental removal of the hard drives.

In addition, the TS-419U supports NAS and iSCSI applications to provide a low-cost, highly 
flexible and efficient IP SAN solution for SMB users. Up to 8 iSCSI targets can be created 
on the NAS for storage expansion of the PC or other servers and backup destination of the 
database servers and mail servers, etc. The TS-419U is featured with virtual disk drive 
(VDD) by built-in iSCSI initiator that other iSCSI devices on the network can be added to 
expand the storage capacity of the NAS.

Moreover, the TS-419U can be accessed across Windows, Mac, Linux, and UNIX. The 
NAS supports EXT3 and EXT4 file systems, and numerous management tools, e.g. 
Windows Active Directory (AD), real-time system monitoring, detailed event logs, Simple 
Network Management Protocol (SNMP), instant SMS alert, schedule power on/ off 
management. The users can make use of all these powerful features to manage the NAS 
efficiently.

(Self-monitoring Analysis and Reporting Technology): HDD 

S.M.A.R.T. offers a quick overview of the hard drive status which 

enables you to monitor the hard drives and check potential 

problems. You can also set the schedule for S.M.A.R.T. test (rapid 

or complete) to ensure the health of the hard disks.

Advanced Hard Drive Protection (HHS): The embedded 

HHS (HDD health scanning) technology supports disk checking 

and bad blocks scanning which helps you discover the 

abnormal issue of the hard disks to prevent disaster.

For business, a high-performance and flexible storage expansion solution for the 

existing application servers is required. However, DAS (Direct Attached Storage) is 

not an efficient solution and a Fiber Channel SAN is too expensive and complicated 

to implement.

Batch Creation of Users and Network Shares: The NAS 

supports batch creation of users and share folders to save your 

time and effort in account and folder creation.

Instant SMS & Email Alert: You can configure the SMTP server 

and SMSC server settings on the NAS in order to receive instant 

system warning or error messages by email or SMS.

Smart Fan: The fan rotation speed is automatically adjusted 

according to the server's temperature. You can also define the 

system temperatures to trigger high speed or low speed rotation of 

the fan. By manually setting the fan rotation speed, the fan will 

rotate at the defined speed continuously.

SNMP (Simple Network Management Protocol) : Enable SNMP 

service on the NAS to actively send the information, warning or 

error of the NAS to max 3 SNMP trap addresses installed SNMP 

management tool. Moreover, MIB of NAS can be downloaded and 

imported to your PC with SNMP tool. Your PC can then acquire the 

info of the NAS actively, e.g. cpu-usage, temperature.

1. Hard Disk Standby: You can configure the hard disks to enter standby mode if 

there is no disk access within the specified period.

2. Schedule Power on/ off: The flexible schedule power on/ off feature enables you 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.

3. Power Resumption Settings: The Turbo NAS can be configured to be turned on or off 

when the AC power resumes after a power loss.

4. UPS Support & Advanced Standby Setting: The Turbo NAS supports the majority of 

USB UPS devices (usbhid-ups supported). You can also set the time for the server to 

enter stand-by mode when an abnormal AC power supply is detected. When the 

power resumes, the server resumes to the operation status before the power outage.

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. Up to 8 virtual disks can be stacked. 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.

The TS-419U can act as a NAS and iSCSI target server at the same time. It provides a 

cost-efficient iSCSI solution to set up an IP-SAN. You can make use of the built-in iSCSI 

target service to add up to 8 iSCSI devices. Different iSCSI Target LUNs (Logical Unit 

Number) can be defined as storage expansion or backup destination of the existing 

application servers, such as database servers and mail servers.

The Surveillance Station enables you to configure and connect IP 

cameras simultaneously and remotely manage the functions. The 

Surveillance Station of QNAP NAS supports all the leading 

network camera brands such as AXIS, D-Link, IPUX, LevelOne, 

Linksys, Panasonic and Vivotek, etc.

With the built-in iSCSI target feature, the NAS can be an ideal solution for 

backup or storage expansion. The users can easily create dedicated virtual 

drives on the NAS for their PCs or existing servers. The iSCSI drives on the 

NAS can be formatted as file system and used as local drives.

The Turbo NAS allows you to create user ID and 

password, and define the authority and quota for each 

user.

You can establish your own FTP 

server by using the Turbo NAS and 

share the files conveniently with your 

friends or customers.

Establish the official website 

to publish information over 

the Internet by the QNAP 

NAS.

The Windows AD feature enables you to import user accounts from 

AD domain to NAS to reduce the time and effort for account setup, 

and the users can use the same set of login name and password.

The automatic backup software, NetBak 

Replicator, is provided for you to perform 

real-time synchronization or schedule backup 

from multiple PCs to the Turbo NAS.

The Turbo NAS can be flexibly applied in various 

deployments such as a database server of another web 

server in remote site or as an additional backup 

database server.

The VDD (Virtual Disk Drive) feature is supported on the 

Turbo NAS that you can use the built-in iSCSI initiator to 

connect to other iSCSI targets on the network to expand 

the storage capacity of the NAS.

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.

The data on the Turbo NAS can be backed up to or from another Turbo NAS or 

Rsync server over the network.

Acronis True Image, CA BrightStor ARCserve Backup, EMC Retrospect, Symantec 

Backup Exec, and LaCie Silverkeeper.

The USB one touch copy button can be configured to trigger instant data backup 

from the external USB device to the NAS or the other way round (applies to the USB 

device connected to the front USB port of the NAS only).

Failover allows the NAS to sustain the failure of one network port to provide 

continuous services.

Bandwidth aggregation is supported to boost the file transfer speed (works with 

managed Ethernet switch with 802.3ad configured).

The NAS can be deployed with two different IP settings for sharing among different 

workgroups in two different subnets.
