[c-nsp] Cisco CSM, maxconns, backup

[Rubens Kuhl Jr.]

I have some doubts about a CSM (Cisco Content Switching Module) that I
couldn't solve y reading docs or searching CCO. Let's think of a
config file such as:

(config file below adapted from docs)

serverfarm WEBFARM
nat server
no nat client
real name SERVER1
inservice
maxconns 1000
real name SERVER2
inservice
maxconns 1000
probe PING
!
serverfarm WEBFARM2
predictor hash address source
nat server
no nat client
real name SERVER3
inservice
real name SERVER4
inservice
probe PING
!
sticky 1 address both

vserver WEB
virtual 10.20.221.100 tcp www
serverfarm WEBFARM backup WEBFARM2
sticky 60 group 1
persistent rebalance
inservice

!

First doubt: will WEBFARM2 be used when all real servers on WEBFARM
max out connections (2000 in this case), if serverfarm WEBFARM is
still up ?

Second doubt: as WEBFARM and WEBFARM2 have different predictor
policies, what will be used if WEBFARM2 starts answering vserver WEB
requests ? Is this configuration legal for the CSM ?


Thanks for any input.
