Trying to figure out how having both openvz and drbd on a two-node server set would be useful. In my half-baked scenario, I'm picturing a thin client setup like this:
----------- ----------- -----------
| client | | client | | client |
----------- ----------- -----------
* * *
********network switch **********
* *
-------------- --------------
| app server | | app server |
-------------- --------------
* *
************network switch ************
* *
---------------- ---------------
| drbd primary | ******xover ****** | drbd backup |
---------------- ---------------
My thought was to have OpenVZ on the "app servers" to run freenx servers, and be able to load balance/migrate sessions between the two "app servers".
Would loading openvz right on the drbd machines be able to eliminate my "app server" layer? Or am I barking up the wrong tree here?
