2 SYSTEM MANAGEMENT Powerful and Intuitive Web-based User Interface The web-based Graphical User Interface (GUI) of the DakotaStor- LX makes remote management of the storage device a simple task. By using a web-browser, the appliance can be easily managed from anywhere within the network over Secured Socket Layer (SSL) Console Tool DakotaStor-LX can also be managed by using the console tool. For security reasons some advanced and critical administrator tasks like removing and restoring volumes and checking and repairing the file system, can only be managed from the console. Through the console tool, an administrator can monitor the status of the network and memory usage, install drivers and hardware and perform other tasks. The operating system supports remote access of the console tool enabling management of the server from anywhere in the network. Superuser Function A Superuser account has unrestricted access to all the files and volumes and is an especially helpful feature when certain directories or files are no longer accessible. Tuning Tools The performance of the operating system can be increased by changing the settings of disk, network, file system or network using Tuning Tools. Multiple Management Levels Three levels of administrative rights are supported: Full Access, Maintenance and Administration. Update System (Local or Internet) Update downtime is reduced with the new Update System feature making it possible to reboot from the old system. NETWORK MANAGEMENT Standard Network Gateway Support DakotaStor-LX can be used with structured networks in business environments and has an optional data access via Intranet or Internet. DHCP Client Assigning IP addresses in a network can be centrally managed and automated through using Dynamic Host Configuration Protocol (DHCP). Multiple Network Interface Card (NIC) Support DakotaStor-LX supports usage of multiple network cards to access separate sub-networks or to increase the bandwidth and allows administrators to select services to be enabled on a specified NIC. Adapter Fault Tolerance (AFT) AFT assures greater reliability by providing a secondary network adapter which automatically takes over, should the primary network adapter fails. Adaptive Load Balancing (ALB) ALB enhances data throughput by automatically routing data through alternative paths as the application changes. 10 Gb Ethernet with TCP/IP Offload Engine (TOE) To improve the data throughput and latency, the Data Storage Server V6 supports 10 GbE to increase bandwidth, improve overall performance, and reduce message latency across connections. InfiniBand Support InfiniBand cards are supported for increased bandwidth, improved overall performance, and reduced message latency across connections. Proxy Settings DakotaStor-LX allows the configuration of the Proxy Server for Internet connections. IP-Sec Secure Internet Protocol (IPsec) is supported for secure data transmitted across a network, preventing confidential and personal information being intercepted or modified. STORAGE MANAGEMENT Automatic Failover for iscsi Volumes DakotaStor-LX provides fault tolerance via iscsi Volume Replication. Data is copied in real time to the primary server and every change is immediately mirrored to a secondary server and in the event of a failure of the primary server DakotaStor-LX automatically switches operations to the secondary server. Automatic Failover for NAS Volumes with NFS protocol (Option) DakotaStor-LX delivers automatic NAS (NFS) failover, based on two nodes of active-passive configuration and provides fault tolerance via synchronous NAS Volume Replication for NFS shares. Once configured, all data written to the primary server is mirrored to a secondary server. In the event the primary server fails, DakotaStor-

3 LX automatically switches operation to the secondary server. NFS locks are also reassigned on the secondary server after primary server fails. This functionality requires the purchase of a feature pack. Volume Replication Both Synchronous and Asynchronous Volume Replication are provided. Asynchronous Volume Replication is also supported over a WAN with both pair to pair support and multiple sources support. Cross Data Synchronization DakotaStor-LX synchronizes files and directories from one NAS server to another. Disaster recovery or Disk-to-Disk backup synchronization utilizes block-based data transfer that minimizes network traffic. DakotaStor-LX can synchronize data in both directions: the DakotaStor-LX can be the source and destination of files at the same time, allowing to cross-backup data on several servers. SCSI-3 Persistent Reservation SCSI-3 persistent reservation commands are supported. This enables support for Windows Server 2008 Clustering. Sys check Enables you to check the performance of your system. Hardware and Software iscsi Initiator DakotaStor-LX supports hardware iscsi Initiators and has a software iscsi Initiator for easily expanding the storage capacity of the NAS server. New units and logical volumes can be added by connecting an iscsi storage system to the NAS server. Notification for RAID Issues alerts are sent to the system administrator in case of issues with the RAID engine. Multiple Fiber Channel HBA Support For higher bandwidth, better latency and performance, the DakotaStor-LX version supports Fiber Channel HBA s from Emulex, Qlogic and LSI. Fiber Channel is the standard connection type for connecting high speed storage devices to computers in Storage Area Networks (SAN). Support for Automatic Session Reassignment (ASR) for Fibre Channel and iscsi protocols Automatic Session Reassignment makes group renaming, removal, and WWN assignment work without interrupting (blocking) other sessions. This functionality makes the iscsi and Fibre Channel services work smoothly while their configuration is being modified. Support for over 2TB Physical and Logical Volumes (LV) DakotaStor-LX supports logical volumes greater than 2TB and a physical size of up to 16TB in 32bit mode. Advanced options for Samba shares DakotaStor-LX supports Inherit owner, Inherit ACL s, Inherit permissions, Map ACL inherit, Locking options. Snapshot Snapshot is an immediate point-in-time image of the logical volume. The snapshot image can be used for both consistent and temporary backup, while users still have uninterrupted and complete access to the logical volume. Files can be recovered from previous snapshots should a file be accidentally deleted or modified. Multiple Snapshots with Scheduling Function Multiple Snapshot with Scheduling is supported 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 or RAID volumes. With its support of multiple logical volume groups, DakotaStor-LX 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 backup and restore data to the volume. Support for Online Capacity Expansion The hardware RAID controllers expansion capability supports the increase of size of existing units without removing data. MONITORING Hardware Monitoring DakotaStor-LX monitors hardware status such as temperature, voltage and fan speed provided by the motherboard s sensors. Simple Network Management Protocol (SNMP) (v2 & v3) DakotaStor-LX uses SNMP for monitoring data throughput, Central Processing Unit (CPU) and Random Access Memory (RAM) usage to name a few.

4 Notification In the event of a technical failure of the storage device, administrators are alerted by . Log Function The DakotaStor-LX log file is an effective instrument in analyzing and solving technical issues. SPECIFIC NAS FUNCTIONALITY Windows Active Directory / Primary Domain Controller Support DakotaStor-LX supports Windows Active Directory (AD), Primary Domain Controller (PDC), Lightweight Directory Access Protocol (LDAP) and AD & 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. Support for Network Information Service (NIS) DakotaStor-LX supports NIS for easier and consistent access of information stored on any other data storage server using NIS directory service protocol by enabling distribution of system configuration data such as user and host names between computers on a computer network. File System with Journaling Support Journaling support makes the file system more reliable and allows easier, faster recovery from unexpected shutdowns. User and Group Quota Control Administrators can control users with large disk requirements by assigning a dedicated share or by restricting their individual usage through individual user quotas or to assign a quota to a group to which the user belongs. Antivirus (server s shares scanning) DakotaStor-LX 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) DakotaStor-LX also supports online scanning of files transferred via the SMB and FTP protocol. USB Storage Support for Dynamic Disk USB Units connected to DakotaStor-LX can be used as a Dynamic Units which can be easily used for local backups. Backup-Agents (Veritas, EMC Dantz, CA BrightStor) Support DakotaStor-LX backup agents help administrators to backup and protect data on NAS servers with backup software from Veritas, Dantz, or CA BrightStor ARCserve thus improving data transfer, network security and real-time directory browsing, monitoring tasks and supporting cross-platform backup support. Supported Network Clients and Network File Protocol DakotaStor-LX supports the file based protocols CIFS (Common Internet File System)/SMB, NFS (Network File System), FTP (File Transfer Protocol), FTPS and Apple Talk enabling Windows, Linux, Unix and Macintosh clients to share data on the same server. External Lightweight Directory Access Protocol (LDAP) DakotaStor-LX supports external LDAP enabling administrators to configure and manage multiple DakotaStor-LX systems from one single point (either a DakotaStor-LX with a LDAP database or any other LDAP server). SPECIFIC iscsi FUNCTIONALITY Multiple Challenge Handshake Authentication Protocols (CHAP) per Target In DakotaStor-LX, CHAP users can be assigned to a specific iscsi target. CHAP is an authentication schema, managed by user name and password, to validate the identity of users to manage the access rights of users to targets. MPIO Support DakotaStor-LX allows you to set multiple connections to one target increasing performance and reliability. Target Password Support DakotaStor-LX allows you to set up passwords for iscsi targets to protect them from unauthorized access. Read Only Logical Unit Number (LUN) This function allows the user to set the LUN as a read-only device (for iscsi Target only). BACKUP FUNCTIONALIY Task Mechanism with Scheduling Management of all the tasks is much easier and convenient using the unified task mechanism with scheduling for data and volume replication, backup and snapshot. Tasks are scheduled as to when to activate and may have many schedules.

5 Virtual Tapes Configure tape drive emulation on share or Dynamic Volume (e.g. dynamically attached hard drive) backup for tape drives is the same as backup on virtual tapes. Worm Worm provides Write Once Read Many functionality for data archiving. NDMP 4.0 Network Data Management Protocol defines a network-based mechanism and protocol for controlling backup, recovery, and other data transfers between primary and secondary storage devices. Tape Library Support Automate backups with use of tape drive libraries. Internal Database Maintain all backup files including backup history. Tape Retention Time Set schedule for tapes to be rewritten for new backup. Local Backup on Dynamic Units Through the DakotaStor-LX, a local HDD or a USB drive can be defined as a Dynamic Unit and acts like a normal tape drive which can backup the NAS server and be removed without shutting down the server. HARDWARE SUPPORT Uninterruptible Power Supply (UPS) Support A UPS eliminates the effects of a temporary power outage and provides a safe shutdown, without loss of data, in case of power failure. The UPS device can be connected by Communications Port (COM-port) or Universal Serial Bus (USB) to the server. Network UPS Support The DakotaStor-LX is capable of using the Simple Network Management Protocol (SNMP) interface for communication with other SNMP-enabled servers for a smooth server shutdown in the event of a power failure. The server with the UPS sends a power failure signal through the network to other servers (in slave mode) and will shut down all servers in the network.
