Genstor HA(High Availability)Cluster Solution

Genstor HA cluster solution is a high availability, business continuous, load balancing solution that allows two servers to be connected together forming a cluster. The function of this cluster is to keep data flowing even if one of the servers fails. To accomplish this failover mechanism, HA Cluster performs functions such as redundant resources management, failure detection, isolation and recovery, logging and notification tasks. Genstor HA based clusters can be configured for one of two operational modes, "Dual Active" or "Hot Standby". In the Dual Active mode both servers share the workload. If one of the servers fails, the remaining server automatically starts carrying the full workload. In the Hot Standby mode, one server is on line carrying the full workload and the other server is in a hot standby mode. If the online server should fail, the standby server will automatically come on line to take over the full workload.

Genstor Systems Inc. now also offers a 'Cluster in a box'. 2 serverboards connected to a common pool of 16 disks. With dual 10GbE connection between the Serverboards via the midplane, if one serverboard fails, the other serverboard is able to take over control and access the HDD's (both controllers can also work as Active-active mode), keeping the system up and running. Storage software is the key to enable this feature, which is available as an option.


  • Automatic Detection: Allows two servers to continually monitor each other for breakdowns and/or irregularities. If one of the servers should fail, the other one will automatically take over.
  • Automatic Switch-over: When HA detects an irregularity, recovery routines are immediately implemented. If the irregularity cannot be resolved locally, operations are switched to other server.
  • Automatic Recovery: Once the failed server is repaired, the administrative person can choose to initiate either an automatic or manual recovery process.
  • Load Balancing: With HA configured for "Dual Active" configuration, both servers will share in the network workload resulting an increase in network efficiency.
  • Automatic or manual failover: In addition to Automatic failover, Genstor HA Solutions can be configured for manual failover. This feature frees up one of the servers to perform functions such as trouble shooting, upgrading and/or scheduled maintenance without causing long interruptions.
  • Automatic Notification: When irregularities or a breakdown occur, Genstor HA Solution will automatically notify pre-selected personal via page or fax messages.

Genstor HPC Cluster Solution

Genstor HPC cluster solutions are customized to customer requirements and budget. They can be based on a 1u with 4 nodes, using Intel® 3000 series Xeon® CPUs or 4 AMD® 6100 series in a 1u for up to 48 cores, etc. With a variety of interconnects allowing low latency for cost-effective performance, the combinations are plenty.

With memory architecture becoming as versatile as it is, and large DIMM sizes being cost-effective, caching and diskmem using memory is extremely appealing. GPU options add to the mix, to give more versatility towards core usage.


  • Host: Intel® or AMD® based, with optimized settings.
  • Interconnect: Gigabit Ethernet, and Infiniband.
  • Memory: Up to 512GB per node.

Operating Systems supported

  • FreeBSD, Linux(various flavors), Windows.


  • Customer spec.
