Package Load distribution

[Sanjiv Sharma_1]

Hi,

I have a two node cluster with 3 LAN Cards each.
LAN 0 for DATA & HB.
LAN 1 for HB
LAN 2 is the STANBY to LAN0.

There are 3 pkg running each node.

Can I distribute the package load on LAN0 and LAN2 and still use it as a failover LAN? If yes how?

I mean to say that LAN0 and LAN2 both will be active. Two packages will be running on LAN0 and one on LAN2. Still LAN0 and LAN2 will be stanby for each other.

Say I am having 5 LAN Cards then can I do it? How? Can I configure LAN0 and LAN4 as DATA & HB with two package running on each and also LAN2 and LAN5 standby for LAN0 and LAN4 respectively. Here LAN1 is HB.

Thanks,
Raje.

Hi,

You configure your LAN cards per node, and not per package, so I don't think you can do what you are asking.

You can get the HP Auto Port Aggregation (APA) software (have to purchase it) and install it. It will aggregate two or more LAN cards together and make them appear as one card. In your case, your lan0 and lan2 would be combined into lan100. If they are 100Mb cards, your lan100 would (pretty much) be 200Mb. The APA software also handles losing one of the cards, so if lan0 dropped out, your lan100 would stay up, just with lan2 at 100Mb.

We use the APA software and it works pretty good. That's probably the closest you'll get to doing what you have in mind.

As john said , APA is your best option . If you don't have APA then you can do something like this :
In subnet x.y.z.0 configure your LAN 0 ( IP x.y.z.1 ) as data and HB . In the same subnet configure your 2 packages with IP's x.y.z.2 and x.y.z.3 . In the same subnet use LAN 2 as standy by for LAN 0 .


In another subnet a.b.c.0 configure your LAN 2 ( IP a.b.c.1 ) as Data and HB . COnfogure the other two packages in this subnet with IP's a.b.c.2 and 3 . Configure lan5 as standy lan .

Use lan1 as dedicated HB .
