Cisco ANM in HA mode

Team,

I need to install two ANM servers in HA mode. The primary ANM server will be in my primary data-center and my back up ANM server will be located in my back up data-center. Is this possible? Based on what I read in the installation and user manual, the servers are supposed to be inter-connected with a cross over cable. Please let me know if what I am trying to do is possible and how can I make this work?

Thank you,

John...

Re: Cisco ANM in HA mode

You may use common VLANs in the data centers and connect the NICs respectively, and I assume it would work as all communication is IP. However, Cisco TAC probably wouldn't support the configuration and it might have some issues due to the bigger round-trip time. So I would keep to the installation guide and confine the servers in the same DC. You may inquire at Cisco whether they would support a direct dedicated fiber crossover connection by means of fiber NICs or media converters or over DWDM provided you can obtain a inter-DC dark fiber. (I don't think they would.)

Re: Cisco ANM in HA mode

Do you have layer2 connectivity between your datacenters?

A prereq. for ANM in HA to work is that your 2 servers are in the same subnet...

What you could do is install them both as primary, manually sync devices and contexts and then rely on auto-sync for the secondary.

Another possibility is to use the backup file of the primary to manually sync the devices and contexts on the secondary.

Re: Cisco ANM in HA mode

Guys,

Thank you for your replies. I'm thinking of configuring both ANM servers as primaries, create a vip in my core ACE module and put the ANM server in my primary and backup datacenters as a real server in a server farm. I will leave the ANM server in my primary data-center as active and I will configure the real server of the ANM server in my backup data-center as standby. What do you think of this solution?

Regards,

John...
