Good day everyone. Recently we deployed new file server on 2012 R2 and decided to turn on deduplication. File server is a VM hosted on 2012R2 Hyper-V cluster. After deploying users start complaining about slow responses from file shares. Also we noticed bigger latencies from our domain controller (also a VM) when it processes requests. Is it really a very big overhead on SAN after turning on deduplication? I didn't find any numbers or tests?
