Microsoft Dynamics - Maximum processing power!

 Mar 05, 2015

In today’s blog I will talk about how to distribute the processing load and offer high availability for Microsoft Dynamics CRM servers.

The most common method of distributing the load on the CRM servers is achieved by installation Microsoft Dynamics CRM on multiple computers. Microsoft CRM consists of a full server, front end server, back-end server and deployment administration server roles. It is best to have multiple instances of these roles running on multiple machines.

It is also a best practice to place the CRM server roles and the SQL running on the same network segment. Hardware redundancy is also required and it is offered by having redundant power supplies, hot swappable memory, and multiple network cards and also by having redundant disks.

Windows network load balancing or NLB can be used to load balance the network traffic. You can also use hardware load balancers. A NLB is a cluster of servers represented by a virtual IP address (VIP). Client request received by VIP are load balanced and equally distributed among the cluster members.

SQL server high availability is offered by configuring clusters, log shipping, database mirroring and AlwaysOn availability groups.

SQL servers can be installed in a failover clustering environment. When one server fails, another server provides service.

Log shipping uses transaction log file backups to update the secondary databases.

Database mirroring increases database availability by mirroring the databases on another SQL server. The primary database computer runs SQL server where the CRM organisation databases are located and the Mirrored database computer runs SQL server with connection to the primary database computer.

AlwaysOn availability group was introduced in SQL Server 2012. It requires SQL servers running on Windows failover clustering nodes. They have a set of user databases called availability databases that fail over together.

Apart from the above components, you need to ensure high availability of supporting components such as Active Directory and Exchange Server.
