Hi all,
I run two instances of FreeNAS/TrueNAS in my envrionment, both backed by gigabit links. I do have 10gbit switches in place and merely need to upgrade the nics on the hosts to provide a 10gbit backing. Before doing so I wanted to have a discussion on the two systems, the current performance and best ways to test, plus what their expected current and 10gbit performance should be.
The systems are both used for VM storage (which I need to improve) and media (which doesn't matter as much).
System 1
Baremetal R710
System 2
R730XD with virtualized FreeNAS on ESXi7
Before plunging into 10gbit with either of these systems and potentially buying SSDs for one of them, I first want to ensure I am thoroughly testing both and getting the most out of either of these systems now, understand what performance I should be seeing and ensure I will see a difference with 10gbit.
Happy for any input, additional tests, recommendations!
Thanks!
