Benefits

High Performance

To facilitate file sharing between different users or platforms, the ZyXEL NSA-2401 network storage

appliance meets the need of small business users with outstanding performance and massive

capacity designed for mission-critical storage management. Its 800 MHz-grade CPU, 256 MB DDR II

memory and dual Gigabit LAN ports empower data reading/writing and network transmission

performance outperforming the competition with the best price/performance ratio.

High Availability

In addition to typical RAID functionalities, the NSA-2401 provides a“hot spare”feature (RAID1 + Spare,

RAID5 + Spare) to reduce down time in the event of driver failure.If any HDD failure occurs, the spare

HDD in the NSA-2401 will automatically take over from the failed one and continue to function

without corrupting the files, or interrupting regular NAS operations.

The NSA-2401 can also collaborate with an optional UPS device to protect files and databases from

sudden power failures or surges.With the NSA-2401 monitoring the power level from the UPS (via

USB) port, the IT staff can be informed of power failure or low UPS power level via e-mail in order to

backup/save important data or shutdown the system safely in time. All these features ensure

maximum device availability.

Easy Capacity Expansion

The IT staff can install cost-effective, low-capacity HDDs on the NSA-2401 for applications that require only a smaller capacity.When demand grows, the

RAID5/JBOD online capacity expansion feature will allow capacity addition through simply installing extra HDDs.

Energy Saving for the Environment

More energy consumption means more carbon dioxide released into the atmosphere.To better protect the environment, the NSA-2401 consumes less

power (only 58 W in access mode, 25 W in idle mode) with no compromise on performance. Compared to traditional NAS and storage servers (normally

consuming 200 W), the NSA-2401 uses 60% less power to save energy as well as the electricity cost.

In off hours such as night time, weekends or holidays with low data traffic, the NSA-2401 can be scheduled to automatically perform power management

according to specific date/time settings or idle time criteria for better power efficiency.

Enterprise-Class Backup Solutions

The NSA-2401 offers an integrated and enterprise-class backup and recovery solution to secure valuable files and databases to run the business smoothly

with less risks of data-loss disaster. It equips with the most popular backup features used by enterprises today,including snapshoot, remote replication,

local backup,instant/scheduled backup, PC client backup and Windows/SQL/Exchange server backup.With Snapshot backup,End-users can instantly

recover a previous version of the file or folder.

To lower the TCO (Total Cost Ownership) an unlimited number of licenses of the Genie Backup Manager Lite software is bundled with the NSA-2401 and

ZyXEL also provides one license for Genie Backup Manager Server software to backup your SQL/Exchange server databases.What used to be considered an

expensive luxury has now been made affordable for small business owners by ZyXEL.

Easy Recovery with Snapshot Backup

The IT staff routinely spends a considerable amount of time and resources dealing with data backup operations; worse yet, the time needed to backup

Terabytes or more of data on traditional tape or disks may becomes a serious headache when facing limited time and resources.To solve this,ZyXEL

presents Snapshot Backup technology.

The Snapshot Backup function creates special“Snapshot” folders in the file system at preset time intervals.The folders allow users to access files of previous

versions anytime when needed, and Snapshot folders can also be browsed and accessed like regular ones.To restore a previous file,simply copy it from the

Snapshot folders. It’s easy and fast.

Most Secure Volume Encryption

Important business files and databases should be securely stored or transmitted to prevent unauthorized access. Hacked or leaked critical information in

the wrong hands may jeopardize confidential information such as financial data, projects in development or sensitive customer information.

In addition to secure FTP/S and HTTP/S file transmission methods, the NSA-2401 also guards the system with Volume Encryption. Volumes or disks can be

encrypted with the robust 256-bit AES algorithm; only authorized personnel with the right password or USB key can access the encrypted data.

Easy Setup, Low Maintenance

Web-based device and disk setup Wizards can help non-technical users setup the NSA-2401 in merely 10 minutes.For first-time installation, the NSA-2401

Discovery Utility also helps with locating and managing the device’s IP address without changing the TCP/IP configuration.

The“S.M.A.R.T.”feature provides complete HDD information.This helps the IT staff pinpoint potential or critical disk issues and to prevent HDD failures or

critical data loss in advance.

Complete logs features, such as event log and Syslog, help the IT staff keep an eye on the system status, access histories and connection status. Should any

critical incident occur, the IT staff will be notified by emails and a buzzer will be activated immediately to warn the on-site personnel.
