slow quick migration

[koala04]

hi

i need to hot migrate a 1,3tb vm machine to new datastoere.
old datastoer are a raid5 hdd, new datastoer are raid10 ssd.
all datastore are in the same server, so no lan transfer.

if i make a quick migration i have a 14mb/s transfer speed... not exactly quick...

the machine with B&R 9.0 are in a vm machine in the same server.
on bootleneck statistic say: 14mb read , 9mb/s wirte

Hi, whatever you're quoting is not a bottleneck statistics. The latter should have 4 components with percent values. Thanks!

where i must search?

Double click a job, check an action log on your right. There should a full bottleneck statistics: Load: Source > Proxy > Network > Target. Thanks.

So it states the target datastore is the bottleneck, is it involved in any other parallel activities?

On your screenshot, can you select VM to the left and see in action log to the right what transport mode is used for each virtual disk?

By the way, this VM-specific action log is where you will see average bottleneck statistics I was talking about (once the job ends). You can also see real-time statistics by hovering over the corresponding UI label in the top left area of the form.

Do you have a virtual backup proxy on the host where this virtual machines are located?

It’s safe to assume that the transfer mode is network so the processing rate looks about right. To be honest power the VM down and use the VMware storage migration tool if you want to stick with migrating the data at the vm container level.
