Support for up to 32 x CPUs

The NAS-R3 supports up to 32 CPUs to increase the I/O throughput for heavy duty data requirements.

Uninterruptible Power Supply (UPS) Support

A UPS eliminates the effects of a temporary power outage and provides a safe shutdown, without loss of data, in case of power failure. The UPS device can be connected by Communications Port (COM-port) or Universal Serial Bus (USB) to the server.

Network UPS Support

The NAS-R3 is capable of using the Simple Network Management Protocol (SNMP) interface for communication with other SNMP-enabled servers (e.g. Open-E NAS-R3) for a smooth server shutdown in the event of a power failure. The server with the UPS sends a power failure signal through the network to other servers (in slave mode) and will shut down all servers in the network.


Windows Active Directory / Primary Domain Controller Support

Open-E NAS-R3 supports Windows Active Directory (AD), Primary Domain Controller (PDC), Lightweight Directory Access Protocol (LDAP) and AD & NIS User-/Group ID synchronization to leverage information about users, groups, systems and other resources stored in the Active Directory. The support of Access Control List (ACL) ensures that access rights of users are automatically taken over from the Domain.

Support for Network Information Service (NIS)

The Open-E NAS-R3 supports NIS for easier and consistent access of information stored on any other data storage server using NIS directory service protocol by enabling distribution of system configuration data such as user and host names between computers on a computer network.

File System with Journaling Support

Journaling support makes the file system more reliable and allows easier, faster recovery from unexpected shutdowns.

User and Group Quota Control

Administrators can control users with large disk requirements by assigning a dedicated share or by restricting their individual usage through individual user quotas or to assign a quota to a group to which the user belongs.

Antivirus (server's shares scanning)

Open-E NAS-R3 has an integrated Antivirus software tool for scanning shares on viruses at predefined points in time. The Virus Definition Database can be updated and is stored on the NAS device.

Antivirus (online scanning)

The Data Storage Server also supports online scanning of files transferred via the SMB and FTP protocol.

Tape Library Support

Make backups with use of tape drive libraries.

Internal Database

Maintain all backup files including backup history.

Tape Retention Time

Set schedule for tapes to be rewritten for new backup.


Support for SWAP

SWAP is used to store memory areas on hard drives instead of Random Access Memory (RAM). The NAS-R3 software dumps memory to SWAP in case of additional memory is needed (e.g. repairing the file system after a degraded RAID).

Liquid Crystal Display (LCD) Panel Support

Open-E NAS-R3 supports single, dual, multiple or pyramid LCD display configuration.

One License per Storage Device

Regardless of the number of users connected to the storage device, Open-E license schema is a one license per NAS-R3 and is priced accordingly. Whether you have 5, 500, 15,000 or more, you only pay one price for one Data Storage Server License.

Superuser Function

A “Superuser” account has unrestricted access to all the files and volumes and is an especially helpful feature when certain directories or files are no longer accessible.

Local Backup on Dynamic Units

Through the DDS, a local HDD or a USB drive can be defined as a Dynamic Unit and acts like a normal tape drive which can backup the NAS server and be removed without shutting down the server.

Cross Data Synchronization

Open-E NAS-R3 synchronize files and directories from one NAS server to another. Disaster recovery or Disk-to-Disk backup synchronization utilizes block-based data transfer that minimizes network traffic. NAS-R3 can synchronize data in both directions: the NAS-R3 can be the source and destination of files at the same time, allowing to cross-backup data on several servers.

Target Password Support

Open-E NAS-R3 allows setting up a password for iSCSI targets to protect them from unauthorized access.
