What's NAS O/S?
NAS(Network Attached Storage) Software
 The NAS O/S is the Operating System installed in NAS. Generally, windows family O/S can be used
for easy application to NAS or when the self-development is not easy, and the customized Linux or
Unix O/S is used to implement a function.
O/S functionality is very important for a NAS. Additional applications as well as Server O/S are
installed in the Server according to the requirements of the user. But NAS is often used standard,
as it was purchased. It is no exaggeration to say that the overall function of the product is wholly
dependent on the NAS O/S supporting functionality.

SPLENTEC NAS Engine Layer
S/W Specifications
- Optimum OS
Based on Linux, Splentec NAS uses a minimized and optimized OS that is booted from 64MB of flash memory, both rapidly and safely. System installation time is less than 15 minutes and safe booting with less than 50 seconds boot time.
- RAID Level 0,1,0+1,5, support
Allows configuring and using RAID in the Stand-alone NAS and between the two NAS units. Supports RAID level 0, 1, 5 and guarantees safe and convenient use with compatible 'Hot Spare' of Hard Disk Drives.
- System Data Backup
System configuration data resides in Flash Memory including network configuration, file system information (RAID, Volume) User/Group Quota, etc. are backed up in HDD. In case of Flash Memory failure, it provides quick restoration to current system environment.
- Security
In the case of Web Interface control, Splentec NAS provides high level of data security by employing encrypted 128bit Secure Socket Layer (SSL) transportation.
- User Quota
Provides User Authorization to access certain volumes and management of capacity allocation.
- Expansion on Demand
Minimized initial investment cost as expansion is possible at any time Expanded units can be integrated with the current volume or it can be used separately.
- Easy management
Control of all disks and NAS units are available through the Web interface. It allows system's surveillance, management and remote area control of temperature, fan and power status. Configuration of volumes, volume resizing, and replication are also available through web interface.
- Storage Virtualization
Other NAS systems supposedly support capacity expansion with clustering of two to a maximum of four units, however, Splentec NAS doesn't limit the number of units to be connected and allows unlimited unit and capacity expansion. In addition, two or more units of Splentec NAS can be connected on both LAN and WAN environments. Additionally Splentec NAS allows configuration of disparate volume sizes of the units in the same area (LAN) and remote areas (WAN). Specifically you can expand the capacity from 0.96TB to hundreds of TBs without the limitation on physical distance as it uses industry standard Ethernet connectivity.
- Dynamic Volume Expansion
Splentec NAS allows resizing of the currently configured volumes. For example, using the User/Group Quota function, the assigned volume of 200GB, 500GB, and 100GB to A, B, and C departments respectively can be resized by simple user operation Dynamic Volume Expansion is also available with the expanded NAS unit.
- iSCSI technology
With the industry's leading technology, iSCSI, Splentec NAS interoperates with other solutions effectively. iSCSI allows Splentec NAS to provide both file I/O (to be used as NAS) and block I/O (to be used as disk array). It is a robust technology that supports configuration of various solutions and functions with Splentec NAS.
- IP Storage & IP SAN
DAS (Direct Attached Storage) or SAN storages that are connected by SCSI or FC(Fibre Channel) reveal some problems in security and has limitation on physical distance. IP-Storage and IP-SAN came along to complement these drawbacks. IP-Storage and IP-SAN provides the following advantages using Ethernet connectivity: - No limitation on physical distance - Interoperable with the existing network environment - Low or none existent maintenance costs - Robust security As 1Gb and 10Gb Ethernet enters the market, it rivals the speed of Fibre Channel. Considering the development pace and interoperability of Ethernet, IP-Storage and IP-SAN are expected to provides new solutions to storage issues.
