Overview of GSLB domain-level affinity
Users need the flexibility to associate a different set of affinities with different domains. For
instance, user may want to direct all traffic from 199.239.0.0/24 subnet to ServerIron ADX A for
domain www.times.com but not for another domain www.travel.com configured on the same
controller. User cannot implement this using the existing global affinity definitions which apply to all
the domains.
This document describes a feature called domain-l
evel affinity which will allow the user to
configure domain-level affinity groups and associate these with the desired domains. As a result,
user has the flexibility of specifying different affinities for different domains. We will continue to
support global affinity. We will support 128 domain-level affinity groups. Each domain-level affinity
group can contain different number of affinity definitions as needed but the total number of affinity
definitions across all the groups including global affinity cannot exceed 1024. User may also use all
the 1024 entries just for global affinity definitions or domain-level affinity definitions. User can
associate a domain-level affinity group with multiple domains. Only one domain-level affinity group
can be associated with a domain.
