OSVault can be used as an archive storage system, as primary NAS storage or as both archive and primary storage.  For those environments where OSVault is used as Primary NAS storage, OSVault can be configured into a highly available storage system. In a highly available configuration, no single hardware failure will interrupt the ability to store and retrieve files stored on highspeed disk storage.

A highly available configuration of OSVault, called OSVault HA, simply requires that two OSVault appliances be installed in close proximity (within Ethernet connection distances) and that a network cable be directly connected between them.  Each OSVault appliance must be of the same model type.

Expansion via iSCSI storage is also supported with OSVault HA, with automatic failover between the two OSVault appliances.  

Failover for access to the tape or optical library requires that the library be Fibre Channel attached, and OSVault fully supports Fibre Channel attachment, with the FIbre Channel Option.

Features and Benefits



Full Redundancy in NAS Services

  • A loss of a disk drive, power supply, input power, network cable link, fibre channel adapter or motherboard will not be noticed by end-users or systems.

Fibre Channel Support

  • Allows for the OSVault server that is taking over to control the tape or optical library and access files that are not stored on highspeed disk.  Also allows for continued copying of new/modifed files to tape or optical storage.

Link Aggregation Support (802.11AD)

  • Allows for network failover without the need for server failover.  Multiple network links appear as one link with higher performance, and loss of one link will only reduce network thruput, not interrupt operations.

RAID-6 Storage

  • Allows for secure storage of recently written data, with the ability of the server to continue operations even after TWO concurrent disk failures. Full redundancy recovery can be done in less than 10 hours while operations continue.
