How to aggregate network interfaces to get a higher throughput.
To aggregate network interfaces the G-RACK 12 uses channel bonding. Channel bonding is a
computer networking arrangement in which two or more network interfaces on a host computer are
combined for redundancy or increased throughput.
1. Press the Network option.
2. You will be presented with 4 tabs. (General, Interfaces, Service Discovery, and Firewall)
3. Select select the Interfaces tab.
4. Click the listing for eth0:
5. Click the Plus (+) option.
6. From the dialog box select the additional interface you wish to bond to the primary Ethernet
interface.
7. Complete the needed fields based on your network requirements.
8. Press save. The values will change quickly on the system. It make take a moment before
equipment on your network notices the change.
How to set higher MTU on Ethernet (jumbo frames).
1. To change the MTU value to the Connect menu.
2. Press the Network option.
3. You will be presented with 4 tabs. (General, Interfaces, Service Discovery, and Firewall)
4. Select select the Interfaces tab.
5. Click the listing for eth0 or the interface you wish to edit:
6. Press the Edit button.
7. The MTU value is at the bottom of the edit dialog box. Enter the appropriate data for your
network.
8. Press save.
ATTO configuration to allow Jumbo Frames
You can achieve the best performance out of the ATTO FF NT12 card if the configuration is set to get
Jumbo Frames on the client. In order for Jumbo Frames above 1500k packet length to/from G-RACK
12 it is imperative that all hardware components (G-RACK 12, Switch, All clients) must be made ready
to receive larger packet sizes. This includes the NIC. ATTO offers a Configuration Tool. Once logged
in, navigate to the NIC FF-NT12 and click the Advanced Tab. Change the ATTO card Maximum’s
I/O Transfer size from ‘default’ to the max of 32MB and press the commit button. NOTE: Make sure
all shares and targets are dismounted as this might cause a slight drop in network connectivity.
Additionally, All clients that wish to use Jumbo Frames will have to make this I/O change to their NIC
when applicable.
If you have any difficulty setting these cards on your network please contact our technical support
