Copying files using VMWare datastore browser
Hi,
Anyone has got an idea on how the datastore copying / Move works . I would like to know more Technical details like which network is used while we copy files using the Datastore browser. Is it the same as how files are copied between VM's?
Environment : vSphere 6.0 and Software iSCSI to HP P2000 G3 SAN
Eg : I am facing slowness when copying Data from a VM to another VM but its faster while copying from one Datastore to another datastore using the Datastore browser.
Thanks in advance.

If you are using the Client (datastore browser), it copies it from the Host to the Client, and back to the Host!

Thanks Andrew. So basically it uses the LAN to transfer the Data as is the case with VM to VM file transfer? I assumed , when we use the Datastore browser , it uses the dedicated SAN network (iSCSI) to copy the data.
What files are being copied by the datastore browser ?
e.g. isos or vmdks ?

Hi Andrew,
It's ISO files. It's fast while copying from data store to data store but very slow within VM's.

Okay, if you copy an iso file from your workstation (client) using the datastore browser, it copies the ISO over the physical network interface from your workstation to the physical network interface in the host (vmnic0) - (the host is attached to the iSCSI LUN via the storage network).
Within the VM is virtualized.... e.g. virtual nic.
Also the virtual machine disks is also virtualized, so the paths are different.

Thanks again , yeah this is clear now. What about copying an ISO file from one Datastore to another Datastore using the Datastore browser? Will it use the client physical network ( a download to the client machine followed by an upload to the other Datastore) . Is that how it works?
