Hallo LVS-list,
I hope Somebody can Help me :)
I need a Linux System which can run 24x7, can do Loadbalancing and Routing.
All Services (Routing/LB) should keep on working no matter what _single_
component fails. (I know that if 2 components fail I have a Problem. :)
At th moment I have 2 Loadbalancers (LB) and while doing tests 2 Real
servers. I would like to use NAT.
I would prefer RedHat Linux 7.2 (that what is on the LB's at the moment)
On the Realservers I have to use Windows NT 4.0 (the application is only
running on that).
Uptill now i have tested with Piranha but my problem is that the Backup LB
does not always takeover. ex. if one NIC goes down on the Primary LB.
Has anybody got a running System where the Backup LB takeover occurs if only
1 NIC (either External or Internal) on the Primary looses its connection ?
What Software are you using ?
!!! Please do not suggest that i buy RedHat HA 2.1 because I have to get it
running till Monday Evening ;) !!!
Infos to my configurtaion : The LB's each have 2 NIC's which each are
connected to a different Switch on each side - that means i have 4 Switches.
ETH0 (on LB) is on the External side and ETH1 on the Internal. The Real
Servers are each connected to one of the above Switches on the Internal
side.
Looks like this :
_____ _____
|Real1| |Real2|
|_____| |_____|

__|__ __|__
|iSW1 |__|iSW2 |
|_____| |_____|

__|__ __|__ eth1
|LB1 | |LB2 |
|_____| |_____|
| | eth0

__|__ __|__
|eSW1 |__|eSW2 |

Thank you in Advance
