Multipath I/O on DSS V6 with Windows 2008

Example configuration of Multipath I/O on DSS V6 with Windows 2008

Hardware Requirements:To run the Multipath I/O on DSS V6 with Windows 2008 server a minimum of two network cards in both systems are requiredTo run the Multipath I/O on DSS V6 with Windows 2008 server, a minimum of two network cards in both systems are required.In this example the DSS V6 system has two NICs with IP addresses: 192.168.5.220 and 192.168.6.220 and on the Windows 2008 system the addresses are 192.168.5.221 and 192.168.6.221. Below is the configuration example.
