There are six Object Storage service Controllers (OSC) in the Huawei Universal Distributed Storage. Each server is a 2U Huawei RH2288 V2 server, equipped with 2x quad-core Intel Xeon E5-2609 CPUs (2.40GHz), 64 GB memory, and 2x 1TB SATA HDDs configured into a RAID-1 group (managed by an LSI SAS2208 RAID controller). There are 4x Gigabit Network Interfaces and 2x 10-Gigabit Network Interfaces on each server.

Network Configuration

The 4x Gigabit Network Interfaces, eth0 – eth3, are unused on each OMS.

The 2x 10GbE NICs, eth4 & eth5, are bonded together into a channel bonding interface bond5. The IP addresses of bond5 are 172.16.1.11 – 13 & 172.16.2.11 – 13, on OSC01 – OSC06 respectively: 

OSC01:~ # cat /etc/sysconfig/network/ifcfg-bond5 
BONDING_MASTER='yes'
BONDING_MODULE_OPTS='mode=balance-xor miimon=100 xmit_hash_policy=layer3+4'
BONDING_SLAVE0='eth4'
BONDING_SLAVE1='eth5'
BOOTPROTO='static'
BROADCAST=''
IPADDR='172.16.1.11'
NETMASK='255.255.255.0'
STARTMODE='auto'
USERCONTROL='no'

OSC01:~ # cat /etc/sysconfig/network/ifcfg-eth4
STARTMODE='hotplug'
BOOTPROTO='none'
ETHTOOL_OPTIONS='-K eth4 lro off'

OSC01:~ # cat /etc/sysconfig/network/ifcfg-eth5
STARTMODE='hotplug'
BOOTPROTO='none'
ETHTOOL_OPTIONS='-K eth5 lro off'

Two VLAN interfaces, vlan3076 & vlan3078, are then created on bond5: 

# cat /etc/sysconfig/network/ifcfg-vlan3076
BOOTPROTO='static'
ETHERDEVICE='bond0'
STARTMODE='auto'
USERCONTROL='no'

# cat /etc/sysconfig/network/ifcfg-vlan3078 
BOOTPROTO='static'
ETHERDEVICE='bond0'
STARTMODE='auto'
USERCONTROL='no'

A bridge interface br1 is created on vlan3078. The IP addresses of br1 are 128.114.126.244 – 249, on OSC01 – OSC06 respectively: 

OSC01:~ # cat /etc/sysconfig/network/ifcfg-br1     
BOOTPROTO='static'
BRIDGE='yes'
BRIDGE_FORWARDDELAY='0'
BRIDGE_PORTS='vlan3078'
BRIDGE_STP='off'
IPADDR='128.114.126.244'
NETMASK='255.255.255.224'
STARTMODE='auto'
USERCONTROL='no'

A bridge interface br2 is created on vlan3076. The IP addresses of br2 are 172.16.6.5 – 10, on OSC01 – OSC06 respectively: 

OSC01:~ # cat /etc/sysconfig/network/ifcfg-br2
BOOTPROTO='static'
BRIDGE='yes'
BRIDGE_FORWARDDELAY='0'
BRIDGE_PORTS='vlan3076'
BRIDGE_STP='off'
IPADDR='172.16.6.5'
NETMASK='255.255.255.0'
STARTMODE='auto'
USERCONTROL='no'

NOTE the setup (by Huawei) is unnecessarily convoluted! The 2 bridge interfaces, br1 & br2, are superfluous. One can simply assign an IP address to a VLAN interface. See:
