Table 2 provides a quick glance at supported and unsupported NIC bonding conguration 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.

Feature Active-passive Link aggregation Adaptive load balancing
Bandwidth Use of 1 NIC at a time provides
interface bandwidth.
Only one interface is active.
Simultaneous use of both NICs
aggregated bandwidth.
All interfaces are active.
Simultaneous use of both NICs
increases bandwidth.
All interfaces are active.
NIC failover protection Yes Yes Yes
Protection during switch
failure in high-availability
conguration
Yes, when NICs are connected to
dierent switches.
No, when all NICs in the LACP group
are connected to a single switch.
Yes, if switch virtualization or IRF
are employed.
Yes, when NICs are connected to
dierent switches.
