iSCSI storage devices provide a cost effective method to access remote external storage devices over an Ethernet network. After installing a network interface card into a PDomain PCIe slot, and connecting the card to an Ethernet network, the PDomain can access external iSCSI storage devices.
Typically, a network interface card is installed in a PDomain that is cabled to an Ethernet switch on the network. After connecting to the network, the PDomain can access a network storage device, attached to the same network, which supports iSCSI protocols (for example, an Oracle ZFS storage appliance). Alternatively, a PDomain network interface card can be cabled directly to the network storage device using Ethernet cables.
During the server installation, you will configure the PDomain to boot off an iSCSI target (for example, a drive or partition) in the external storage device. Once configured, you can install the Oracle Solaris OS on the device.
Each server PDomain must be configured to boot off of a storage device. Installing and cabling additional network interface cards, especially in different CMIOUs within the PDomain, can provide redundant connections to the Ethernet switch or networked storage device.
