VAAI UNMAP - reclaim-unit for a netapp storage

[binoyrc]

Hi,

I am using "esxcli storage vmfs unmap" command to reclaim the deleted blocks from datastore. There is a parameter -l reclaim-unit to be mentioned in this command if we don't want to use the default value of 200. I would like to know what will be the suitable reclaim-unit value for a Netapp storage? Is there a easy way to find this value?

Regards

Binoy

Did you ever manage to find the answer for this? I want to run this against my NetApp storage as well but have read the vmware KB article and advises to speakt to storage vendor about what is the best practise value.
