Feature Summary:

Web-based Graphical User Interface
The powerful and convenient Web-based GUI (Graphical User Interface) of the Celeros EZNAS XN  software makes remote management of the NAS server a simple task. By using a web-browser, the server can be easily managed from anywhere in the network.
 
Remote Access of Console Tools
The XN series supports remote access of the console tools, enabling the management of the NAS by the console tools from anywhere in the network.


Secured Administration Access
The Celeros EZNAS XN  server can be accessed and configured by the web-based, password-protected GUI over Secured Administration Access (SSL).

Console Tools
The Celeros EZNAS XN  server can also be managed by using the console tools. For security reasons some advanced and critical administrator tasks like, removing and restoring volumes, checking and repairing the file system, can only be managed from the console. From the console tools, the NAS server can monitor the status of the network, installed drivers and hardware, memory usage and others.

Email Notification
Administrators will be automatically alerted by Email, in the event of a technical failure of the NAS server.

Multiple Management Levels
Administrators can be assigned different rights. The Celeros EZNAS XN supports three levels: Full Access, Maintenance and Administration.

Update via web
With one click the server can check for new updates. New updates can be downloaded and installed remotely on servers at different locations.

Windows Active Directory / Primary Domain Controller
Celeros NAS supports Windows Active Directory (ADS), PDC, LDAP and ADS & 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.

External LDAP
Celeros EZNAS XN  supports external LDAP servers to enable users to configure and administer multiple Celeros EZNAS XN  servers from one single point (either an Celeros NAS server with a LDAP database or any other LDAP server).

Support for Network Information Service (NIS)
The NIS directory service protocol enables the distribution of system configuration data such as user and host names between computers on a computer network. Celeros EZNAS XN  supports NIS for easier and consistent access of information stored on any other Celeros EZNAS XN  server using NIS.

File System With Journaling Support
The support for journaling makes the file system more reliable and allows easier, faster recovery from unexpected shutdowns.


User and Group Quota Control
Users with large disk requirements can be constrained either by assigning them a dedicated share or by restricting their individual usage through individual user quotas or to assign a quota on a group to which the user belongs.

Standard Network Gateway Support
Celeros EZNAS XN  can be used in business environments with structured networks and has an optional data access via Intranet or Internet.

DHCP Client
By using the support of Dynamic Host Configuration Protocol (DHCP) the process of assigning IP addresses in a network can be centrally managed and automated.

Log Function
For technical support and troubleshooting purposes, the Celeros log file is an efficient instrument in analyzing and solving technical issues.

Superuser Function
The “Superuser” account has unrestricted access to all the files and volumes. This is especially helpful if a user has left the company and certain directories or files can not been accessed.

Supported Network Clients
Celeros NAS supports the file based protocols CIFS/, NFS, FTP, Secure FTP and Apple Talk enabling Windows, Linux, Unix and MacIntosh clients to share data on the same NAS server.

E-mail notification for  RAID
Celeros EZNAS XN  can be configured to send Email alerts to the system administrator in case of any problem with the RAID subsystem.

Antivirus (server's shares scanning)
Celeros EZNAS XN  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 for  protocol)
The Enterprise version also supports Online Scanning of files transferred via the  and FTP protocol.

SNMP (v2 & v3)
The Celeros XSR supports the SNMP protocol to monitor e.g. the data throughput, CPU, RAM usage of the NAS storage system.

S.M.A.R.T. Support
The Celeros EZNAS XN  includes S.M.A.R.T. for detecting and reporting the status of the HDDs to anticipate failures.

E-mail notification for S.M.A.R.T.
Due to the S.M.A.R.T. feature, Celeros EZNAS XN Enterprise can be configured to send Email alerts to the system administrator in case of any problem with the hard drive units.


iSCSI Initatior
Celeros EZNAS XN Enterprise supports hardware iSCSI Initiators and has a software iSCSI Initiator for easily expanding the storage capacity of the NAS system. New units and logical volumes can be added by connecting an iSCSI storage system to the NAS.

Backup-Agents (Veritas, EMC Dantz, CA BrightStor)
Celeros EZNAS XN 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
Celeros 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)
Celeros EZNAS XN  can be a destination for data transfer from another Celeros EZNAS XN  server.

Support for over 2TB physical and logical volumes
With Celeros EZNAS XN  you will be able to build Logical Volumes greater than 2TB. As well, use physical volumes (e.g. RAID units) greater than 2TB.

Snapshot
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
Celeros EZNAS XN 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, Celeros EZNAS XN 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-EZNAS XN Enterprise is capable of using the SNMP interface for communication with other SNMP-enabled servers (e.g., Celeros EZNAS XN 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.
