i use esxi 6.7 update1
and some vm is configurationed the mscs for physical rdm. for windows 2016
in case of not pRDM , use vmdk with vmware datastore
disk format speed is good
but in case of pRDM , in the MSCS vm
pRDM disk format speed is very slow
same disk is 300GB
one disk(vmdk)format speed is 5~7 second
the other one disk(pRDM) format speed is more than 30second.
i reconfig the vm many times but speed is not good
Is there a way to change the settings to speed up formatting speed?
Changing format speed?
Never saw a question like that.
Formatting a LUN will take the time required for the array, and there are some factors that help to do it or not as VAAI for example.
Also if the LUN you are formatting is zeroed previously or not, disk type, etc.
