This post is for them as well as. We value the opportunity these SQL events. However with TCP Chimney enabled, you notice there is a marked delay between a batch completed and the start of the next batch for the exact same series of statements and work. In this example, note how there is approximately a ms. In this scenario with the ms. This type of delay can affect application throughput as well as concurrency. TOE also requires very large changes to a networking stack in order to be supported properly, and even when that is done, features like Quality of Service and packet filtering typically do not work.
Proprietary — TOE is implemented differently by each hardware vendor. This means more code must be rewritten to deal with the various TOE implementations, at a cost of the aforementioned complexity and, possibly, security. Furthermore, TOE firmware cannot be easily modified since it is closed-source. TOE does not increase bandwidth on the network. As hardware performance increases, processes can complete their task prior to TOEs acknowledgment of the receipt of transmission; thus causing communication issues.
A transport-level error has occurred when sending the request to the server provider: TCP Provider, error 0 - An existing connection was forcibly closed by the remote host. Some cluster applications require TCP Offload Engine to be enabled on each cluster node or replica for proper functionality. As such, it is recommended not to edit any TCP Offload Engine settings for servers that are nodes or replicas in a clustered environment without first consulting the cluster application documentation.
If the cluster documentation clearly confirms TCP Offload Engine settings can be changed without any negative effects, then proceed with the changes after creating a plan to roll back the changes if needed. If the NIC teaming documentation clearly confirms TCP Offload Engine settings can be changed without any negative effects, then proceed with the changes after creating a plan to roll back the changes if needed.
