We are currently using NetApp and intend to change the storage next year. Our choices are between NetApp and Pure. We are a transport company, so part of the decision will be based on the price.
All storage vendors have good solutions now.
We are not using NetApp AFF, we are using NetApp with the disks and a bit of Flash.
We have a flash pool with our NetApp and we want to go to full Flash next year.
I would rate NetApp AFF an eight out of ten.
