Have a Cisco UCS C-240 with 12 2TB 6G SAS HDDs, connected through a Cisco 12G SAS HBA (no RAID, LSI based).
64 GB RAM, and 2x 24 core (hyper-threaded) Xeon E5-2670 v3 CPUs at 2.3 GHz.
1 SSD (16GB reserved) for ZIL in the pool.
Setup with LZ4 and no de-dupe as below:
I have 2 datasets on this pool. When I try to copy a large file (~25 GB) from one dataset to the other, I am getting around 75MB/s speed, as reported by rsync.
Is this expected performance? Should I not be seeing higher throughput?
