Copying Files within a datastore from emc VNX 5400?

did you use vmkfstools ?

no through vSphere client.

i've always had very "so so" performance when using the client, it would be curios if you could try vmkfstools ? Otherwise is the array really busy ? It could be that those 15 drives are already working really hard.

vmkfstools –i -d thin

I am monitoring the disks through VNX monitoring and reporting tool. It isnt busy. I havent tried the vmkfstools, never tried it . will check on that. will it be because of spindles being used for reading and writing simultaneously!!

that could be it as well, contention.

Is there some way we can do a fine tuning?? so that performance would be better??

it maybe not a disk issue, maybe it's the vSphere client ...try vmkfstools and see what you get.

There wasnt any big difference when we used vmkfstools.

i have not used VNX monitoring and reporting tool for a while so i can't remember what metrics you can get out of it, do you see IOPS per LUN or anything of that nature ?

an extra enabler ? Isn't it included in Block OE ?

Check VAAI copy offload – you need an Enabler for that

It is a free enabler – called ODXcopy I believe

isn't that for SMB3 offload ?

Hi, How can i check this??

yes we can see IOPS per lun.. reads and writes as well
