2. Accessing Virtuozzo Infrastructure Platform Clusters via iSCSI¶
Virtuozzo Infrastructure Platform allows you to export cluster disk space outside Virtuozzo Infrastructure Platform bounds to operating systems and third-party virtualization solutions. Using dedicated vstorage-iscsi tools, you can export Virtuozzo Infrastructure Platform disk space as LUN block devices over iSCSI in a SAN-like manner.
In Virtuozzo Infrastructure Platform, you can create and run multiple iSCSI targets per Virtuozzo Infrastructure Platform cluster node. In turn, each iSCSI target can have multiple LUNs (virtual disks). At any given moment, each iSCSI target runs on a single Hardware node. Thanks to high availability, if a node fails, iSCSI targets hosted on it are moved to and relaunched on a healthy node.
The figure below shows a typical network configured for exporting Virtuozzo Infrastructure Platform disk space over iSCSI.
In this example are three Virtuozzo Hardware nodes working in a Virtuozzo Infrastructure Platform cluster. Two nodes host one iSCSI target each while the third hosts two iSCSI targets. Each node has a static or dynamic IP address assigned from the Storage BackNet (created along with the Virtuozzo Infrastructure Platform cluster) and the FrontNet. Each iSCSI target has a static IP address assigned from the FrontNet.
