is having problem, on the other hand the stats that i have showed with
command "rsync" was the proof of concept that the file transfer b/w Proxmox
and Storage is doing fine. but the problem part is inside VM. which is
Windows 2003 server.

Here you're showing that you don't have a problem with your storage.

i will share the diagram of results.

the connectivity is like this. i have 3 servers all in 1 broadcast domain
(Samba storage server, Proxmox Server and OmniOS server). all can ping each
other. means OmniOS server is not behind the Proxmox they all are in same

i have a 700MB ISO image which i demonstrated in the graphics that was
attached to my last email. i copied that 700MB file to that Samba box and
then i copied that same file from Samba box back to VM and use windows
share/SMB for copy and pasting the file.

NOPE! i am not using virtio neither disk nor in Ethernet. is it important
to use virtio when using storage box? because i have never used External
boxesbefore i only used local storage with RAID1 (mdadm) and used same old
RAW and QCOW images. and they were perfectly fine for me.

Please advice.
