Secure NAS 2R5

The Secure NAS is a family of storage appliance from Addonics that combines the benefits of RAID storage, Network Attached Storage (NAS), Direct Attached Storage (DAS) and hardware AES 256-bit encryption all in a box. It is an ideal solution for storing a large volume of sensitive data, for securely transporting a large volume of data between different locations or for any application that requires protection against data theft.

The Secure NAS can be directly attached to any system via high-speed eSATA connection, this allows transferring a large volume of data quickly. The same data in the Secure NAS can be shared over a 1 Gigabit network. The entire RAID volume, including the boot sector and partition table, is encrypted. Data written onto or retrieved from the RAID is encrypted and decrypted on the fly by a high-performance FIPS certified AES 256-bit crypto engine.

The Secure NAS has also added new powerful features beginning 6/16/2014 via a new firmware release. There are now full disk sharing and existing folder sharing from drives created by other systems. Shares can be applied to both FTP and SMB for different users and with different READ/WRITE privileges. These new features allow quick set up of sharing information on existing drives through LAN and WAN, making it an ideal tool for setting up a private Cloud storage. It is also a great tool for sharing information on existing drive on a private network such as at home or a temporary LAN without any elaborate administrative setup.

The encryption is simple to operate. There is no software to run or password to enter. Simply insert a correct cipher key into the unit during the system startup, just like starting a car. Once the unit is powered up, the Cipher key can be removed. If the Secure NAS storage unit is stolen, the RAID volume will not be visible on the network or to any system. If the drives are taken out from the Secure NAS storage and directly attached to any system, the drives will appear as blank. There will be no trace of any recoverable data even examined by recovery software or surface scanning of the drive platter.


About this model

The Secure NAS 2R5, model SN1035E1G-S, accommodates up to ten (10) 3.5" SATA hard drives. The ten drives are set up as two RAID volumes for high performance and reliability. By using RAID 5 configuration, each RAID volume up to 16 TB can be created by using five 4TB hard drives. The entire RAID volume, encrypted by a FIPS certified AES 256-bit crypto engine, can be directly attached to any system via eSATA or used as a Network Attached Storage appliance on any 10/100/1000 network.

Additional USB drives, up to maximum fifteen (15) drive volumes when combines with USB hubs, can be shared over the network by attaching to the USB port on the back of the unit.

Cipher Key programming software
For an organization with large deployment, you may consider managing your own keys by ordering the optional RNG software suite

HMAC key: The cipher code in the HMAC key is encrypted and stored in a protected secret area. The code cannot be copied or READ by any mean should the key is lost or stolen.  To program another HMAC key with the same cipher code, the original key file used in creating the cipher code is required.


Direct Attached Storage

  • To configure the RAID of the drives attached to the Port Multiplier (PM) - To set the RAID configuration of each Port Multiplier inside the unit using the PM management software. Please note that when attached to an eSATA port that is not PM compatible or a USB port, only the drive attached to the Port 0 of the PM will be detected by the Disk Management. But under the PM management utility, all the drives attached to the PM are visible and can be configured to different RAID settings.
