![]() We standardized on deploying servers with at least four (4) network adapters – In my previous life as a data center engineer, Private communication traffic to the production network or, even worse, cause unexpectedĭepending on how your network is designed, you can have several networkĪdapters for different purposes. Will not overly saturate the network or you run the risk of redirecting the WSFC The amount of transaction log records generated on your primary replica databases You can leverage the dedicated WSFC private communication networkįor the SQL Server Availability Group data replication traffic. (about 134 bytes) and will use all the available network paths to the different Besides, the WSFC private communication packets are very lightweight Want just the WSFC private communication traffic to be the only traffic going thru Own network devices for the WSFC private communication traffic. Let’s say you’ve configured a dedicated network adapter with its You still have a single point of failure. On the network adapters when they are all plugged in to the same network switch – Provide redundancy in terms of an additional network with its own switches and routers.īecause it doesn’t make any sense to provide high availability and resiliency I would go beyond the concept of configuring network adapters in a teamed pair and ![]() System might see it as a single network adapter although, in reality, you have several. I know some serverĪdministrators would argue that you can have multiple network adapters that areĬonfigured in a teamed pair to address high availability and resiliency. While this may be specifically for the networkĪdministrators, it affects how SQL Server deals with meeting recovery objectivesĪnd service level agreements for highly available databases. Goal for building a WSFC is high availability and resiliency. You to build a WSFC with a single network adapter, I don’t recommend it. While Windows Server 2008 and higher server operating systems allowed Having a dedicated network for internal cluster (also known as heartbeat or private)Ĭommunication.
