Chapter 1: Introduction
Overview
Thank you for choosing the Thecus IP Storage Server. The Thecus IP storage is an
easy-to-use storage server that allows a dedicated approach to storing and
distributing data on a network. Data reliability is ensured with RAID features that
provide data security and recovery—over multiple Terabyte of storage are available
using RAID 5 and RAID 6. Gigabit Ethernet ports enhance network efficiency,
allowing Thecus IP storage to take over file management functions, increase
application and data sharing and provide faster data response. The Thecus IP
storage offers data mobility with a disk roaming feature that lets you swap working
hard drives for use in other Thecus IP storage, securing the continuity of data in the
event of hardware failure. The Thecus IP storage allows data consolidation and
sharing between Windows (SMB/CIFS), UNIX/Linux, and Apple OS X environments.
The Thecus IP storage’s user-friendly GUI supports multiple Languages.
Product Highlights
File Server
First and foremost, the Thecus IPstorage allows you to store and share files over an
IP network. With a Network Attached Storage (NAS) device, you can centralize
your files and share them easily over your network. With the easy-to-use
web-based interface, users on your network can access these files in a snap.
To learn about the Web User Interface, go to
Chapter 4: Using the Thecus I P Storage > Web Administration I nterface
FTP Server
With the built-in FTP Server, friends, clients, and customers can upload and
download files to your Thecus IP storage over the Internet with their favorite FTP
programs. You can create user accounts so that only authorized users have access.
To set up the FTP Server, refer to
Chapter 4: Netw ork Service> FTP .
iTunes Server
With the built-in iTunes server capability, the Thecus IP storage enables digital
music to be shared and played anywhere on the network!
To set up the iTunes Server, refer to
Chapter 4: Application Server>iTunes Configuration.
Printer Server
With the Thecus IPstorage’s Printer Server, you can easily share an IPP printer with
other PCs connected to your network.
To set up the Printer Server, refer to
Chapter 4: External Devices Server> Printer I nformation.
Multiple RAI D
7

Thecus IP storage supports multiple RAID volumes on one system. So, you can
create RAID 0 for your non-critical data, and create RAID 1,5,6,50 or 60 (depend
on model) for mission-critical data. Create the RAID levels depending on your
needs.
To configure RAID modes on the Thecus IP storage, refer to
Chapter 4: Storage Management > RAI D I nformation.
iSCSI Capability
Thecus IP storage is not only a file server, but it also supports iSCSI initiators. Your
server can access Thecus IP storage as a direct-attached-storage over the LAN or
Internet. There is no easier way to expand the capacity of your current application
servers. All the storage needs can be centrally managed and deployed. This brings
ultimate flexibility to users.
To set up an iSCSI volume, refer to
Chapter 4: Storage Management > iSCSI
Superior Pow er Management
Thecus IP storage supports schedule power on/off. With this feature, administrator
can set at what time to turn on or off the system. This feature is a big plus for
people who want to conserve energy. Wake-On-LAN enables administrator to
remotely turn on the system without even leaving their own seat.
To schedule system on and off, refer to
Chapter 4: System Management> Scheduled Pow er On/ Off
