i have clarifications regarding exchange 2010 High availability.
the current environment two sites, site A and site B connected through 1Gb link.
2 edge Load ballanced
2 CAS servers (cas array)
2 HUB servers
High availibilty will be configured as below:
Cas array on site A, in case of site failure we should point the cas array to site B cas server
two send connectors will be created on the edge servers with different cost.
send connector A: will have the 2 HUB servers on site A with cost 1
send connector B: will have only the HUB server on site B with cost 10
incoming Email and owa:
creation of two MX records, so two A records should be there for the same name, for example:
for site A: SmtpA 10.10.10.10 TTL 1h
for site B: SmtpB 10.10.10.11 TTL 1h
site A: MXA smtpA priority 0
site B: MXB smtpB priority 10
Site A OwaA smtpA
Site B Owa B smtpB (manually created after site a fails)
1- is there a way to make cas servers failover automatically?
2- this is the way to configure Hub servers failover?
3- how long does it take to start using MXB in case of site A failure and is it automatic
4- how to configure OWA failover, is there a away to makes it automatic?
