Bond Mode
Description
 The order of received data is uncertain.
 Low network throughput.
Active-Backup
 Definition: The default bond mode. Transmits data via a specified data NIC,
other data NICs are standby. Only when the specified data NIC fails, another
standby data NIC takes over transmission task.
 Advantage:
 There is no requirement about hardware like network switch.
 Redundant network links.
 Disadvantage:
 Load balance isn’t supported.
 Uses only one data NIC at a time. Other data NICs aren’t fully used.
Balance-xor
 Definition:
 The storage system can figure out the relationship between each data NIC
and clients’ MAC addresses. According to the relationship, storage system
transmits data to clients with corresponding data NIC. If the working data
NIC fails, another data NIC takes over the task.
 It is recommended to use this mode in a local area network. However, if
data is transmitted via network gateway, don’t use the mode.
 Advantage:
 There is no requirement to hardware like network switch.
 Balance the load in the local area network within a network switch.
 Disadvantage: Load balance isn’t supported in different local area network.
Broadcast
 Definition: All the data NICs transmit the same data.
 Advantage:
 There is no requirement about hardware like network switch.
 Redundant network links.
 Data NICs are fully used.
 Disadvantage:
 Load balance isn’t supported.
 Low data NIC usage.
802.3ad
 Definition: The storage system figures out the relationship between each data
NIC and clients’ MAC addresses according to Hash Algorithm. Storage system
transmits data to client via corresponding data NIC.
 Advantage:
 Based on IEEE standard, devices in system can work efficiently if they are
all 802.3ad mode.
 Load balance.
 Data NICs are fully used.
 Disadvantage: Storage system, network switch, and client server are all required
to support 802.3ad mode.
Balance-tlb
 Definition: Storage system allocates output traffic to each data NICs, according
to current load. And transmits data to clients via different data NICs. If the
working data NIC fails, another data NIC takes over the task.
