I plan to install a traffic management software on HPE Proliant blades. They are in the middle of the traffic path, (the traffic path being: clients + access network + HPE blades + NAT + Internet). I need to load balance the traffic with layer-4 flow affinity: all traffic with the same IP addresses and ports will go through the same blade in both directions.
I was thinking to use HP 6127XLG Blade Switch, which has a flow-sharing functionality. There seems to be a command to do just that. From page 118 of Layer 3 - IP Services Configuration Guide:
ip load-sharing mode per-flow [ tunnel { inner | outer } | algorithm algorithm-number | [ dest-ip | dest-port | ingress-port | ip-pro | src-ip | src-port ] * ] [ slot slot-number ]
(See http://h20565.www2.hpe.com/hpsc/doc/public/display?sp4ts.oid=8732034&docLocale=en_US&docId=emr_na-c04763596)
Has anyone used this switch in this scenario?
To keep the affinity on both directions, do I need two switches (one with rules based on destination address/port and the other one with rules based on source address/port)? or can it be done with one single switch playing with the undocumented algorithm-number?
An finally, how will that work in the event of a blade failure? Will the traffic be distributed to the remaining blades?
Thanks in advance!
