Storage vMotion and Cloning a VM to a different host it going at a rate of 20MB/s. The network is a 10G network with SSD's as the storage. I'm running the latest mid-July release of ESXi 6 and both hosts are freshly installed. I've tried a 1GB network adapter instead and I get the same results. Where should I start looking?
So I pulled the SSD's from the system and it turns out they were both defective. I benched them and here are the results I got.
Are you using Jumbo Frame? If yes, have you verified JF are set up properly everywhere?
I have ESXi 6 in my lab with 10Gb connectivity and SSD storage. Typically clone is at 300-400MB/s speed. vMotion speed varies.
Hi there,
Could you please if the VAAI feature is enabled ? Also confirm if you are trying to copy from local storage of a host to another hosts local storage ? Also confirm if MTU is been set to JF . (9000)
What storage is it?
You can check if VAAI is enabled with the following commands:
esxcli system settings advanced list -o /DataMover/HardwareAcceleratedMove
esxcli system settings advanced list -o /DataMover/HardwareAcceleratedInit
esxcli system settings advanced list -o /VMFS3/HardwareAcceleratedLocking
The "Int Value" output must be set to 1
You can monitor VAAI in esxtop:
check if there is a traffic shaping policy active on your vSwitch that limits the outgoing traffic.

BTW - is HP P822 Smart Array support VAAI?
VAAI is designed for Storage-arrays connected through Fibrechannel, ISCSI and NAS (>vsphere 5.0).
The HP P822 is a raid controller for local Storage i suppose. So no, it's not supported.
thanks!
