Storage & Volumne Management

  • Large Capacity Volume Support - Supports up to 24TB per single volume for LA models
    Supports over/beyond 24TB per single volume for LG models (note #3)
  • Multiple Volumes - Supports up to total of 80 volumes per NAS; and 33 volumes per physical LUN. Total capacity can be divided up between iSCSI volumes and NAS volumes.
  • Flexible & Powerful RAID Configuration - Remote email notification for disk failure, plus alert by audio alarm RAID controller supports S.M.A.R.T. monitoring and remote notification
    • For LB models: internal hardware RAID controller with RAID-0, 1, 3, 5, 6, 0+1, and + Hot-Spare
    • For LG models: external hardware RAID boxes with RAID-0, 1, 3, 5, 6, 0+1, and Hot-Spare
    • For LG models: RAID-on-RAID feature supported. Volume-Manager can select one of the following RAID configurations for volumes from external RAIDs or iSCSI targets:
      • RAID-0 to aggregate external volumes/LUNs for high data throughput.
      • RAID-1 to mirror two external volumes/LUNs for extra redundancy.
      • One-on-One just simply create One NAS volume on each external volume/LUN
      • Spanning/Pooling/LinearRAID just simply create a big volume
  • Capacity Scalable - LG models natively support external RAID boxes via interfaces of: U320 SCSI, 4Gb Fibre FC, iSCSI. LB models support LG-Enabling with optional license upgrade.
  • Quota Assignment - Supports storage quota assignments to individual group or to individual users.
  • Volume Snapshots - Supports multiple Snapshots for ‘point-in-time” user data image against accidental user file deletion and data corruption or virus attack. Snapshot can be scheduled or on-demand.
  • Multiple NAS Aggregation - Existing NAS can also grow its capacity by utilizing its iSCSI initiator, and make the new NAS as an iSCSI target, then mount it into the existing NAS as if it is part of the local storage, and then grow the existing volume.

Easy Deployment, Setup, & Maintainance

  • NAS-Finder, the included NAS discovery tool will automatically discover any and all NAS units in the local network, and allow Administrator to manually add an entry for remote NAS unit over internet/VPN/WAN.
  • Use Web Browser for Admin to open the Administrator Web GUI page, no need to know any thing about the OS itself. Supported Web Browser: IE6 and up for Windows, Firefox/Mozila for Linux
  • “One Click” on-line OS upgrade and patch installation
  • Incorporated Web GUI for the hardware RAID controller setup and management
  • Detail and Intuitive Event Log
  • Downloadable System Log can be saved and email to manufacturer for analysis just in case.
  • NAS resource utilization status can be viewed from the administrator Web GUI
  • On-Line Users and Folder-being-accessed  can be viewed from the administrator Web GUI

Data Protection & Backup

  • NAS-to-NAS Folder Replicator included for NAS-to-NAS Folder/File Replication over LAN, WAN or VPN/Internet for remote data redundancy. It is Scheduled and Block-Level/File-Based with Versioning, or Full Replication with Compression, Throttle Control and Bandwidth Control.
  • NAS-to-NAS Mirroring/Failover is an optional function that allows two(2) NAS units to be mirrored in the same LAN and provides one virtual IP to clients for data accessing. In case the primary NAS has failed, the secondary NAS will automatically take over. The mirroring and failover is automatic and transparent, so data accessing to clients is uninterrupted.
  • NAS-to-NAS Remote Volume Async Mirroring  is an optional function that allows a volume of the local NAS to be mirrored to another volume in a remote NAS over LAN, WAN or VPN/Internet.
  • RAID-on-RAID  function on volume manager allows you  to mirror(RAID-1) two LUNs from external RAID storage boxes to provide extra redundancy
  • Volume Snapshot allows Admin to automatically create multiple and scheduled “point-in-time” Snapshots of a NAS volume. The copy of the snapshot can be transferred and stored elsewhere for backup/restore purposes. Snapshot-on-demand is also supported.
  • System Configuration Backup & Restore. NAS system configuration includes: volume configuration and user info. It can be saved to Admin’s computer and stored elsewhere. In case of hardware failure, a new NAS unit can replace an old one, by using the “Restoring” option on the admin web GUI. (system configuration can easily restored from this backup)
  • USB Backup allows backup to USB attached disk devices.
  • Local Tape Backup. Rackmount models allow installation of optional PCI SCSI HBA for external SCSI Tape drive/auto-loader/library to support local tape backup.
  • 3rd Party Backup Agent Support. The NAS includes RPM as part of the OS, so most of the 3rd party backup agents should be able to install, such as: Netbackup, Backupexec, Amanda, BRU, Legato’s Network client, etc.

Fully Interoperable

  • All models of Sans Digital Linux NAS product line are fully interoperable for folder replications.
  • Can be deployed across multiple remote offices & locations.
  • A major building block for a  total enterprise solution from Sans Digital Linux NAS.

iSCSI – Target & Initiator

  • iSCSI Target function allows a certain portion(s) of the storage to be partitioned as iSCSI volume(s) and assigned to specific host computer, appearing as if a local disk to that host computer and provides block device services instead of file services.
  • iSCSI initiator function allows the NAS to mount remote iSCSI target volume as its local physical storage, and then create NAS volumes or iSCSI volumes on top of it.
  • Combination of iSCSI Target and Initiator support between multiple NAS units can be used as one of the method to do Multi-NAS-Aggregation for capacity scalability.
