Why Use a Clustered HA Storage Pool Configuration

QuantaStor's clustered storage pool configurations ensure high-availability (HA) in the event of a node outage or storage connectivity to the active node is lost. **Needs a little more flushout**

Requirements for a Clustered HA Storage Pool Configuration

Creating a QuantaStor Clustered HA Storage Pool will require:

  • At least 2 QuantaStor appliances
  • 2 network interfaces with separate networks for redundant cluster communication
  • Shared storage available to all systems in the cluster
    • SAS JBOD(s) or SAN-delivered block storage over Fiber-channel (preferred) or iSCSI

QuantaStor's High-Availability Storage Pool solution requires that the QuantaStor appliance cluster members all have access to the Storage Pool devices. Because of this requirement, the storage used for a HA Storage Pool must either be from a SAS JBOD enclosure capable of supporting multiple hosts, or for higher performance configurations, a SAN delivering block storage (LUNs) to the QuantaStor front-end appliances over FC (preferred) or iSCSI.
