Hi
I added new nodes to my cluster I was using cisco servers add new nodes with dell servers but I faced performance issue during writing data on new
volumes
To be consider I didnt change anything in configuration or network side.
The only difference in hardware vendor can this impacted on performance.?
Thanks

Performance depends on the hardware being used, so yes if you have different hardware configuration serving the same pool, the performance of the pool will bottleneck at the lowest performing hardware. Always best use similar performance hardware, at least within the same storage pool.
It is also possible the performance impact is due to the re-balance traffic when you added new nodes, you can lower the backfill speed in the maintenance page or make sure it is not set too fast.
