38 VxFlex Network Deployment Guide using Dell EMC Networking 25GbE switches and OS9
A Troubleshooting SDS connectivity
SDS connectivity problems affect VxFlex performance. VxFlex has a built-in tool to verify all SDS nodes in a
given protection domain have connectivity. From the VxFlex Command Line Interface (SCLI), run the VxFlex
internal network test to verify the network speed between all the SDS nodes in the Protection Domain.
The command below tests all SDS nodes with a payload of 10 GB, using 8 parallel threads.
