Exchange 2013 and High Availability
Shawn presented on Exchange 2013 and High Availability at Tech Talk Live on May 6, 2014. In this presentation, Shawn examined some of Microsoft’s improvements to Exchange 2013 High Availability. Many of these are the continuation of ideas implemented in Exchange 2010 and have been further refined. He chose a few that he finds interesting to share. Below is a short synopsis of what is covered.
- Exchange 2013 has greatly reduced the amount of IOPS required for passive copies. This allows for more efficient balancing of server resources. The allowance for multiple databases and types of databases per a single volume is also aimed at balancing server resources.
- AutoReseed allows for an almost RAID like automatic disk reseed in JBOD environments.
- Managed Availability constantly monitors critical Exchange functions and can notify administrators as well as perform automatic recovery options.
- Lagged database copies have been much improved and can now automatically play themselves down and recover missing mail from Safety Net.
- Maintenance Mode is a continuation of setting DAG members offline, but has been rewritten for the newer Exchange architecture.
Together these improvements show great work being done to keep Exchange up and running at all times. Whether you use all the features or just a few, this will give you a primer to start looking into the features further.
