Exch2010 DAG - Bandwidth / connection type
Posted on 2013-06-04
We're trying to revisit our DAG setup that is active and passive nodes in two separate state lcoations. GA and NY.
Both active and passive nodes hold the Hub, Client, and Mailbox roles of the five roles.
Each site connect via hw vpn established over 10 m fiber.
4 Dbs(50,55,60,47 gb) with log files ranging from 2,3,5, and 10g presently/at this second.
1. DAG works best over MPLS or VPN hw like Sonicwall or WatchGard or checkpoint? If can do/invest in MPLS should we just default to implementing that.
*when something happens at our passive node site getting the CQL right and db back over to GA is grueling and once we even had to have things sneakermailed bc it just wouldn't seed and/or come back(copy) on line in GA, successully.
2. Do we have the roles necessary for users to actually get their mail from the passive node(NY) during a failover, because as things are (inherited) mail barely works when this happens. OWA doesn't and mail may or may trickle into some users. mostly not.
