Bond Mode Description
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 network interface at a time. Other data network
interfaces aren’t fully used.
XOR

Definition:

The storage system can figure out the relationship between each data
network interface and client MAC addresses. According to the relationship,
the storage system transmits data to clients with corresponding data
network interface. If the working data network interface fails, another
data network interface 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 network interfaces transmit the same data.

Advantage :

There is no requirement about hardware like network switch.

Redundant network links.

Data network interfaces are fully used.

Disadvantage :

Load balance isn’t supported.

Low data network interface usage.
802.3ad

Definition : The storage system figures out the relationship between each data
network interface and clients’ MAC addresses according to Hash Algorithm. The
storage system transmits data to client via corresponding data network
interface.

Advantage :

Based on IEEE standard, devices in system can work efficiently if they are
all 802.3ad mode.

Load balance.

Data network interfaces are fully used.

Disadvantage : The storage system, network switch, and client server are all
required to support 802.3ad mode.
Tlb

Definition : The storage system allocates output traffic to each data network
interfaces, according to current load. And transmits data to clients via different
data network interfaces. If the working data network interface fails, another
data network interface takes over the task.
