Exchange 2010 – The real driver to virtualized Exchange environments
Filed Under Exchange, Virtualization | Leave a Comment
With Exchange 2010, there are so many new features and capabilities from management, performance, HA, and more!
E2k10 is a lot of information, and I’ve been slowly “ingesting”.
One of my favorites is the new Database Availability Groups “DAGS”.
The Exchange Engineering Team has completely re-engineered the capabilities for HA. Hats off to them definitely!!
Yes, there are is no more Exchange clustering, SCR, LCR, CCR and all of those things you might have heard me speak about in the past.
These were such touted follow ups (from Exchange 2003) in Exchange 2007.
The new features in Exchange 2010 offer great benefits and build a great case to further the virtualization of Exchange deployments.
With Database Availability Groups (DAGS), Exchange Admins will be able to replicate and failover databases instantly whether locally or remote.
There are no more restrictions on the Exchange roles that can be installed for HA purposes. With Exchange 2010 you have the ability to get your environment going now and adding DAG capability later with little restrictions. This is concept is known as incremental deployment and breaks down the barriers that Exchange 2007 has with its HA and recovery features. Also, you can failover a single or multiple databases without having to failover the entire Exchange Server and much more!!
Not to mention, the great performance and I/O reduction in Exchange 2010 will definitely be a virtualization case builder for transitions and migrations to Exchange 2010. I believe these new capabilities will yield fast benefits, facilitate, and further drive virtualized Exchange environments.
Here is a video performing a database switchover using DAGS.
Enjoy!
