Hi Storage experts,

My vms on Xenserver are very slow on booting up, all of this vm's are hosted on the storage which is QNAP TS809-U RP.

Question is, am I having some storage performance issues with I/O judging from the hdfarm & iostat below?

hdfarm from XenServer to Storage

hdparm output - from Xenserver to QNAP
iostat from the QNAP shell/terminal
