Active/Passive VIP - 2 different DC's
Hey guys,
Just working on a VIP deployment which will see an active passive topology but based across 2 DC's each having their own HA pair. I was thinking about priority groups in terms of having each others members in the pool.
From the VIP perspective what would you advise? Obviously each DC will need it's own VIP(GTM not in place)
Cheers
Suppose you have 2 group Servers. DC1 Servers & DC2 Server. On Priority Group Activation
Commom_pool_DC Method: Load Balancing Method & Priority Group Activation (1) Available Member
1) x.x.x.x:xx Priority 10
2) x.x.x.y:xx Priority 10 3) x.x.x.y:xx Priority 104) a.a.a.a:pp Priority 20 5) a.a.a.a:pp Priority 20 6) a.a.a.a:pp Priority 20
If minimum available member will be lesser then 1 then traffic will move to other DC servers. Assign to VIP.
Other option to create two VIP with respect to DC. Apply iRule to VIP-1
when HTTP_REQUEST { if { [active_members [LB::server pool]] == 0 } { HTTP::redirect "http://VIP2.com" } }
Paste if any problem
