Table 2 provides a quick glance at supported and unsupported NIC bonding configuration for StoreVirtual systems
installed with 1 and/or 10 Gigabit NICs. Note: In a mixed 1GbE and 10GbE active/passive bond, it is a best practice to set
the 10GbE NIC as the preferred interface to ensure maximum throughput in a known good state. Bonding of bonded
interfaces is not supported.
