Hi all,
I got an performance trouble with my iSCSI initiator over bonding interface.
Whenever I use bonding, my iscsi performance decreases.
Here is my environment:
Sun X4150 server with Red Hat 5.5
EMC CX4-480 iscsi target
My servers two onboard gigabit ethernet ports are connected to two different
Cisco Switches
Hi,
Is there a particular reason you are using bonding? is it a CX4
requirement? I have always, without fail achieved higher performance
in my (Equallogic) environment using device-mapper-multipath. There
are a lot of settings to play with re: tunings, and Dell (for example)
is silent on most, but I've been able to achieve both line-rate or
iops saturation with dm-multipath...
This machine is a test machine and also I was testing xen environment
formerly, and this bonding is just NIC bonding not XEN.
I am using dm-mpio for multipath with CX4 on iscsi but I don't trust
one switch for server nic so I connect my two server ethernet nic port
to two different switches. In brief I want a failover NIC bonding mode
1. However, when I use mode 1, iscsi performance decreases. I dig a
little google and read /usr/share/doc/iputils-20020927/README.bonding
file for a clue but I couldn't find anything.
