Yes; The VIO-4000 series appliances are the best price / performance solution for providing servers with very high performance access to iSCSI storage arrays. Servers connect to an iSCSI storage array using iSCSI capable virtual 10Gb Ethernet NIC provided by the VIO-4000. Software based iSCSI initiators are used to connect to iSCSI targets. Newer 10Gb capable iSCSI storage arrays can connect directly to the VIO-4000 appliance's 10Gb Ethernet ports. Legacy 1Gb iSCSI storage units can be attached to a 1Gb Ethernet switch. The 1G Ethernet switch has 10Gb uplink ports that can be connected directly to the 10Gb Ethernet port of the VIO-4000appliance . The Virtensys iSCSI storage access to the server is provided by a high performance, low latency PCI express based link between the server and the VIO-4000 appliances.
