Dell Technologies recommends that you:
- Set the minimum number of nodes for production workload to seven for a PowerFlex two-layer configuration.
- Ensure that all the compute nodes and storage nodes have the same hardware configuration for predictable performance. Homogenous node types are recommended.
- Set the number of SDS threads is set to 12 for all the SO nodes.
- Separate the management and data traffic from production application traffic. This separation can be done by using VLANs.
- Use the Noop I/O scheduler for all the SSD devices discovered.
- For each SDC set the number of operating system threads for the network to 12 by using the following parameter:
scli --set_performance_parameters --all_sds --tech --sds_number_os_threads 12
