Veritas Flex appliance - network bond layers
We have a flex 5360, and we duplicate to an access 3350
We have been seeing performance issues, and they were resolved by changing the xmit_hash_policy layers
By default it is layer2, needs to be changed to layer3+4!
ssh to flex, run "support shell" command to get limited shell
cat /etc/sysconfig/network-scripts/ifcfg-bond0
BONDING_OPTS="mode=802.3ad miimon=100 xmit_hash_policy=layer3+4"
If you don't have the layer3+4, you are not using all your outbound NICS!
Our flex was setup by Veritas and even after almost a year of calls for issues no one realized this was configured less than optimally!
I am seeing tremendous improvement in throughput after making the change and rebooting my flex.
