I noticed the speed of storage vMotion is quite slow in my config.
I built a lab a small inexpensive lab at home to improve my VMware skills.
I have 2x diskless ESXi 6.5 hosts which are connected to a SAN storage server (ESOS) via FC (4Gbps).
In my storage server I have 3x SATA spinning disks, each configured as their own LUN/datastore.
I've installed vCenter with operations manager (trial).
Now when I move one VM from a datastore to another, it takes quite long, average speed is ~30 MB/s:
I did several tests and it seems the performance issue is at the VMware level:
Looks like something is not optimized in my VMware/ESXi config and I think if i managed to improve iSCSI performance, I'll see the same with FC.
