You can configure SnapDrive for Windows to employ both a Windows cluster and a storage system active/active configuration connected through a GbE switch using MPIO.
The following illustration shows a Windows cluster and a storage system active/active configuration with an optional but recommended dedicated network for internal cluster traffic.
Each storage system in this configuration requires at least two Fast Ethernet (or GbE) NICs to connect to the data-center fabric. (See your Data ONTAP Block Access Management Guide for iSCSI and FC for details.)
