If I turn off FT, the file copy takes 2 seconds.  If I turn on FT, the file copy takes 50 seconds.  I can understand the impact of NOT using 10G for a busy VM. There would be a lot of stuff to copy to the second VM.  This is an idle VM.  There's nothing running on it.  It's just a generic Red Hat install.  I would think 1G would be enough to handle the copy of a 200MB file.
Not currently but I will be in production.  I'm just not sure why that would be a factor.  Is it because the test file I'm copying has to be copied to 2 machines?  If that's the case, I would exp... See more...
Not currently but I will be in production.  I'm just not sure why that would be a factor.  Is it because the test file I'm copying has to be copied to 2 machines?  If that's the case, I would expect the copy to take twice as long not 25 times longer. To add more details, the cluster I'm using has 3 hosts and there's 3 VMs running across these hosts. So, there's really no other network traffic going on.
I'm in the process of testing FT in a newly setup vSphere 6 environment.  What I'm noticing is that file copies from an NFS share across the network are MUCH slower when FT is enabled.  With FT ... See more...
I'm in the process of testing FT in a newly setup vSphere 6 environment.  What I'm noticing is that file copies from an NFS share across the network are MUCH slower when FT is enabled.  With FT on, a 210MB file copy takes 50 seconds.  With FT off, it takes about 2 seconds.  This is a Red Hat 7.1 VM.  The NFS share is on another VM on a different host in the same cluster.  Has anybody else seen this?  I don't have a 5.5 environment to compare this to. I haven't even tested fail over yet.  If this is the performance I can expect, I'm not sure it's worth it.
