Adapter Fault Tolerance (AFT)
Adapter Fault Tolerance assures greater reliability by providing a secondary network adapter which automatically takes over if the primary network adapter fails.

Adaptive Load Balancing (ALB)
Adaptive Load Balancing enhances data throughput by automatically routing data through alternative paths as the application changes.

10 Gb Ethernet with TCP/IP Offload Engine (TOE)
To improve the data throughput and latency, the Open-E NAS-XSR Enterprise and supports 10 Gbit Ethernet cards from Chelsio for servers and storage systems. Chelsio provides the highest 10GbE performance available. With the on-board hardware that offloads TCP/IP processing from its host system, the Chelsio card lets its host give more CPU cycles to applications. The result: the system gets increased bandwidth, improved overall performance, and reduced message latency across connections.

InfiniBand Support
You can use InfiniBand cards for connecting servers. InfiniBand is modern, high-speed (up to 10Gbit) serial computer bus.

Proxy settings
With Open-E software you can use proxy server for Internet connections.

Multiple CPU Support (32x)

Backup-Agents (Veritas, EMC Dantz , CA BrightStor)
Open-E NAS-XSR Enterprise backup agents help administrators to back up NAS servers with backup software from Veritas, Dantz , CA BrightStor ARCserve. Using the backup agents, you can administer complete data protection for all data stored on the NAS server. This improves data transfer and provides network security, task monitoring, real-time directory browsing, and cross-platform backup support. Other backup software can do the backup and restore over supported file protocols.

Local Backup on Dynamic Units
In the Enterprise version a local HDD or a USB drive can be defined as a Dynamic Unit. On this Unit you can backup the NAS server and store the backup separately. The Dynamic Unit can be removed without shutting down the server and acts like a normal tape drive.

Cross Data Synchronization
Open-E NAS can synchronize files and directories from one NAS server to another. The data transfer is block- based in order to minimize network traffic. Synchronization can be used for disaster recovery or Disk-to-Disk backup purposes. The Enterprise version can synchronize data in both directions: the NAS server can be the source and destination of files at the same time, allowing to cross-backup data on several servers

Synchronization (Destination)
Open-E NAS-XSR Enterprise can be a destination for data transfer from another Open-E NAS-XSR Enterprise server.

Support for over 2TB physical and logical volumes
With Open-E NAS-XSR Enterprise you will be able to build Logical Volumes greater than 2TB. As well, use physical volumes (e.g. RAID units) greater than 2TB.

Snapshot is an immediate point-in-time image of the logical volume ( LV ). The snapshot image can be used for both consistent and temporary backup, while users still have uninterrupted and complete access to the LV. Also, if a user accidentally deletes or incorrectly modifies a file, that file can be recovered from a previous snapshot image.

Multiple Snapshot with the scheduling function
Open-E NAS-XSR Enterprise supports “Multiple Snapshot with Scheduling” to create snapshots at predefined points in time (e.g. Automatically every hour).

Multiple Logical Volume & Groups
Logical volume groups allow storage administrators to create logical storage pools that span multiple physical disk drives. With its support of multiple logical volume groups, Open-E NAS-XSR Enterprise makes it easier to meet the changing needs of users and applications while making the maximum use of available physical disk space.

Online Logical Volume Expansion
Online logical volume expansion allows administrators to change the size of storage volumes as needed without having to restart the application, recreate the volume, and back up and restore the data to the volume.

Support for Online Capacity Expansion
This feature supports a RAID controllers' capability to increase the size of existing units without removing your data.

UPS Support
Uninterruptible Power Supply (UPS) eliminates the effects of a temporary power outage and provides safe shutdown, without loss of data, in case of power failure. The UPS device can be connected by COM-port or USB to the NAS server.

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

No individual client or server licenses are required
With Open-E NAS-XSR Enterprise, it doesn't matter how many users you have on your network, whether there are 5, 50, 500, or more: You pay the same price for Open-E NAS-XSR Enterprise
