ADC Clustering across DC and DR


Recommended Posts

 

Hi there,

We have two SDX-15030 in DC and two SDX-15030 in DR site. Latency will be about 40msec between both sites.

We are using Cisco and formed APIC cluster such that POD-1 is running in both datacenter active-active.

In the similar fashion, we want to run Citrix ADC SDX platfrom so that single instance can run in both datacenter active-active. Is it possible and how do we create ADC cluster in this situation?

 

 

Thanks.

One method is to use GSLB to do active/active to separate VIPs in each site. 

 

40 msec latency is much higher than a typical metro cluster. 

 

Otherwise, see https://docs.citrix.com/en-us/sdx/12-1/configuring-management-service/set-up-a-cluster-of-netScaler-instances.html. To get traffic to the cluster nodes, you'd need Layer 3 ECMP to the VIPs, or Layer 2 LAG across both sites.  ADC supports Layer 3 clusters if you're not stretching Layer 2 subnets. https://docs.citrix.com/en-us/netscaler/12/clustering/cluster-overview/configure-l3-cluster.html
