Answer

  • The two main factors in throughput are latency and concurrency. Low latency and high concurrency will achieve high throughput
  • Concurrency can be divided into two operations:
    1. Data in flight, or queue depth
    2. Multi-threading
  • NFS nConnect or SMB3 Multichannel can achieve this with multiple TCP streams
    • It is recommened to test SMB3 multichannel on a test vserver prior to enabling it on a production vserver and limit possible impacts due to misconfiguration on clients
    • More about Multichannel
  • Multithreading can be increased with multi-threaded copy tools such as NetApp XCP, robocopy/rich copy in windows, rsync in linux.
