Altostratustraffic load balanced to CAS server very unevenly
Customer has a pair of ISA to terminate HTTPS connections for the 3 backend CAS servers. LTM is located between ISA and CAS. So below setup.
client -------> ISA --------> LTM ----------> ...

AltostratusThanks for all reply.
From the command I can only see this.
root@BIGIP01(Active)(tmos) show ltm persistence persist-records
Sys::Persistent Connections
source-address 10.0.0.40:80 10.0.0.49:80 0
source-address 10.0.0.40:80 10.0.0.49:80 1
source-address 10.0.0.40:80 10.0.0.49:80 0
source-address 10.0.0.40:80 10.0.0.49:80 1
Total records returned: 4
10.0.0.40 is the VS ip address, 10.0.0.49 is the heavy loaded server ip address. I do not see the ISA ip address.
When I look at the persistence records statistics in WebUI, I found these records.
Persistence Value Persistence Mode Virtual Server Pool Pool Member Age
10.0.0.29 Source Address Affinity VS_HTTP HTTP_POOL 10.0.0.49:80 0 seconds
10.0.0.29 Source Address Affinity VS_HTTP HTTP_POOL 10.0.0.49:80 0 seconds
10.0.0.30 Source Address Affinity VS_HTTP HTTP_POOL 10.0.0.49:80 1 seconds
10.0.0.30 Source Address Affinity VS_HTTP HTTP_POOL 10.0.0.49:80 0 seconds
10.0.0.29 and 30 are ip address of ISA servers.
However, since similar problem happened before and I made a post here, someone told me that as long as the source address persistence is configured ( although as backup method), the persistence records will still be created even if not used.
