DIRECT ATTACHED STORAGE FEATURES
High Performance
Sans Digital DAS rackmounts are built to meet the highest level of storage demands. The rackmounts are dedicated to enterprise environments for performance intensive applications, such as database, mail server, video editing and high performance computing. The rackmounts utilizes various host interfaces, such as 4 Gbps Fibre Channel or Serial Attached SCSI (SAS), supporting up to 850MB/s of performance.
Easy Management
Sans Digital DAS rackmounts are designed with LCDs, RS232 ports, or firmware-embedded web interfaces for simple RAID array configuration, system hardware monitoring, and error alert viewing. The SMTP feature is included, which notifies the administrator via email when critical errors occur. No additional software or plug-in is required, allowing the administrator to manage the unit locally or remotely using any form of operating system.
RAID 6 Mode
RAID 6 array is an extension of the RAID 5 array with additional parity stored across the RAID set. The second parity allows the failure of a second hard drive without causing down time or losing data. RAID 6 is an ideal solution for critical data applications that require minimal down time.
High Availability
Designed for mission critical applications, Sans Digital DAS rackmounts are backed by high available features such as redundant and hot-swappable components, and proactive event monitoring software. The Sans Digital towers and rackmounts support dual-host interfaces, MPIO setup, or clustering server applications to insure further data protection and redundancy.
Highly Scalable
Sans Digital DAS rackmounts series includes models that support both SAS and SATA hard drives, as well as SAS expansion, which are building blocks for high capacity storage infrastructure. SAS drives are faster in performance, where as SATA drives are cost-effective with higher capacities, allowing users to choose the most suitable solution to meet their storage demands. The included Mini-SAS ports utilize SAS expanders, allowing the possibility of expansions where one RAID head-unit could lead up to seven JBOD boxes, or 192TB total capacity. The versatility of the SAS features permit long life cycles where the capacity of the rackmounts could be expanded when needed.
Online RAID Migration & Expansion
Utilizing dedicated high performance IO processors and advanced RAID design, Sans Digital DAS rackmounts are capable of real-time RAID mode / strip size alteration, and hard drive capacity expansions without the need to power off the unit. There is no need to move existing data to a temporary location. All changes are performed in the background, without interrupting data availability.
Modularized Design
Sans Digital’s AccuRAID series utilizes fully modularized designs that replace all interconnecting cables with connectors. RAID controllers, cooling fans, disk drives and power supplies could be easily hot-swapped to eliminate data access down time. Additional rackmount parts and accessories are available for prompt replacement.
Multiple RAID Volumes
Sans Digital DAS rackmounts support multiple RAID volume, where different RAID modes could be setup within a single unit, allowing flexibility for various different environments and applications. A multi-bay rackmount could be divided into smaller volumes that could be operate and administrated individually.
Array Roaming
To provide increased protection and immediate support, each RAID configuration is stored in both the NVRAM and the hard drives. In case of a hard drive or controller failure, RAID configuration is preserved, allowing the administrator to move the complete RAID set to another system without losing RAID configuration and most importantly, the data inside the RAID set.

NETWORK ATTACHED STORAGE FEATURES
Linux Edition
The EliteNAS Linux series is a feature-rich NAS platform that provides the ultimate performance for a mixed network. These unified storage solutions supports both iSCSI SAN block-based sharing and NAS files-based sharing within a single enclosure. The EliteNAS Linux series supports CIFS with Active Directory Service, NFS and Apple Network, where data could be sharing simultaneously amongst various operating systems. Folder replication, snapshot, and iSCSI initiator and target are included at no additional cost.
Windows Edition
The EliteNAS Windows series allows the installation of third-party Windows compatible software for feature expansion. Based on Windows Server technology, Windows edition fully supports Active Directory Server to ensure seamless integration of the Mircosoft Network settings. With built-in Volume Shadow Service, as well as Microsoft management interfaces, the Windows NAS series is the ideal choice for establishing pure Windows network environments.
Easy Management
The NAS series could be easily integrated and maintained via an OS independent Web GUI, where no additional software is needed. Server utilization, log files and system configuration file are available for download. Critical data status and updates could be sent via E-mail to notify the administrator. CLI, SSH and Telnet features are available to further enhance the administration experience. ADS and NFS allow the use of Web GUI to assign user rights. For administrators that do not have access to ADS or NFS servers, local access right control could also help insure file security. Multiple management options allow administrators to integrate, configure and manage the NAS units locally or remotely with ease.
Mixed Network
EliteNAS Linux series supports a mixed network by including NFS, CIFS and Apple Network features. Integration and setup of a mixed network could be easily done via the build-in Web GUI interface. In a mixed network, the Linux based NAS are faster in performance in comparison to Windows NAS.
NAS-to-NAS Folder Replication
Built-in NAS-to-NAS folder replication provides a local or remote backup solution for network storage. A chosen folder within a EliteNAS array could be replicated, or copied, to local folders or remote locations as long as the receiving units are also EliteNAS Linux models. Replications could be performed on demand or scheduled hourly or daily to satisfy the storage need of environment. Block-level, differential replication with bandwidth control, is supported to further reinforce a seamless data replication and backup process when performed from a remote location.
Server Mirroring Failover
Server Mirroring Failover (SMF) is an optional license that allows real-time synchronized block-level data replication between two NAS units. The data between two iSCSI or NAS units are mirrored, where both units contain the same data and storage volume. When the primary NAS unit fails, the secondary NAS unit will take over without loosing data access time until the primary unit is back on line.
Snapshot
Snapshot is a copy of a set of files and directories as they were at a particular point in the past. The snapshot feature provides local file retrieval where users could recover their individually stored data on previous snapshots without the assistance of the administrator. Snapshot could be implemented flexibility as on-demand or scheduled actions.
File-Based (NAS) / Blocked-Based (iSCSI) Storage
The NAS rackmounts support both iSCSI (block-based) IP SAN storage and file-based Network Attached Storage within a single unit. Administrators now have the choice of using iSCSI to support applications that typically require or perform better with block access (such as SQL Server and Exchange), or NAS for better file-level I/O performance.
iSCSI Initiator and Target
The EliteNAS and MobileNAS series is capable of being an iSCSI initiator or target. An iSCSI initiator functions as an iSCSI client, to initiate a block-based storage format. An iSCSI target represents additional storage expansion based on an existing iSCSI initiator. The flexibility to perform both initiator and target allows EliteNAS and MobileNAS to create or expand via IP based Storage Area Network (SAN).
Gateway Option
A one-time gateway license with unlimited storage expansion capability is available. The EliteRAID series is dedicated hardware based RAID 6 storage subsystem supporting SAS and SATA drives with SAS expansions. Adding the EliteRAID series to an AccuNAS Gateway model, along with additional AccuSTOR models, allows the capability of capacity storage in an IP SAN or NAS network environment.
Fully Customizable
The NAS series are customizable by utilizing PCIe or PCI-X adapter cards. Options include installing Fibre Channel cards for additional Fibre Channel storage units to create NAS-SAN hybrids. A 10GB Ethernet card could be installed for 10GB networking, to allow high performance transfer rate of over 600MB/s, or high storage capacity of over 200TB.
