Implementing networking for S2D
Arguably the most important part of an S2D cluster is the network. If the networking components of the cluster are not well designed or not implemented properly, you will most likely experience performance degradation, low bandwidth, and high latency, among other issues between cluster nodes.
One of the big advantages of using S2D is the simplicity of networking configuration and the reduction of CPU usage (by as much as 30% or more, given proper remote-direct memory access (RDMA) network interfaces and design). Let’s review the minimum and recommended network requirements for S2D.
The following networking requirements are recommendations from Microsoft:
- Minimum network connectivity for a two to three-node cluster:
- 10 Gbps (or faster) network interface(s)
- Two or more network connections from each node recommended to improve both redundancy and overall performance
- Recommended network connectivity for a high-performance cluster ...
