Hi,
Thank you for the repsonses. I've checked the DelayedACK and it is Selected.
I have now contact DELL regarding this. We have SC Series SAN with all the datastores on there. I will wait for there response.
From what I've read, It's a case of putting each ESXI host into Maintenance Mode and then deselecting this option. I take it this can be done one by one assuming DELL come back and advised this option needs deselecting?
Many Thanks
