I am testing OVM moving VM local disk to different repository within same Storage array - XtremIO
The array is supporting VAAI operations (XCOPY , ATS , TRIM) however during moving VM disk to different Repository (different LUN in same storage) , the performance is much lower than ATS operations can provide.
I am talking about 500 MB/s when VAAI XCOPY operation is used, the Bandwidth can reach 10 GB/s .
Same storage vMotion operations works fine in VMWare environment.
Thanks and sincerely yours,
