Large Capacity Storage and File Sharing
Cross-platform Sharing with Antivirus
The TS-420U 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 TS-420U ensures business continuity by offering detection against the latest viruses, malware, worms, and Trojan horses.
Windows Active Directory (AD) and LDAP Directory Service
The Windows AD and LDAP (Lightweight Directory Access Protocol) directory service features enable the IT administrator to retrieve user accounts from Windows AD or LDAP-based directory server to the TS-420U, reducing time and effort in account setup. Users can use the same login name and password to access the TS-420U. In addition, the TS-420U can also be configured as an LDAP server and allows devices with LDAP protocol enabled to be joined in the directory and share the same user accounts and groups.
Shared Folder Aggregation
Access the shared folders of other servers on Microsoft Networking through the "portal folder" on the TS-420U. This saves the time and effort in logging in multiple servers one by one.
ISO File Archiving and Sharing
The TS-420U supports mounting ISO images of CD and DVD discs as network shares for data archiving, storage, and sharing. This feature saves the space for storing the physical discs, reduces the risk of data loss caused by disc wearing and tearing, and enhances the efficiency of data sharing on business network.
Advanced Folder Permissions
Advanced folder permissions allow users to configure folder/subfolder access to the TS-420U. With this feature enabled, users can manage the folder permissions from Microsoft Windows or the web-based management interface of the TS-420U easily.
