Problem with SvMotion on vSphere 5.5u2 | Nutanix Community
Skip to main content
Hi,



On a new install (nx6020) ; during a Storage vMotion, the ESXi CPU increases up to +80% of the total physical CPU ...The Storage vMotion is very long ...

A vMotion is ok, no problem, very fast.

Any idea ?



Info :

- Cluster version v4.1.2.1

- RAM CVMs : 32GB



I think that there is not enough RAM on CVMs ?... 32GB its a best practices.



thks guys !

Thanks for asking YCASTILLO



Can you add any insights here dlink7 DonnieBrasco cbadami



Thanks 🙂
Can you please run following command and check if VAAI plugin is enabled on the ESXi Hosts



esxcli software vib list | grep vaai



Time taken by Storage vMotion will also depend upon the size of the VM. Also are you performing storage vMotion from some third-party presented datastore to nutanix NFS datastore ?



As far as 32GB RAM is concerned, it is enough for the CVM.

the command result : "nfs-vaai-plugin 1.4-10e909fa Nutanix CommunitySupported 2015-05-13"

The VAAI are OK on ESxi.



The Storage vMotion is between two Nutanix NFS datastore on the same cluster.

The VM is not a big monster ! :o)



Thks !

For information, i tested a clone with a VM, the problem is the same.... So its not the ESXi kernel vMotion.

I noticed that during a Storage vMotion or a clone, the physical CPU utilization was increased by + 50% on the ESXi hosts providing the VM, but also on other Nutanix cluster of ESXi, the CPU increased by + 20% ...



This information can be help ...



Thks !Sig'
