Average servers don't tend to have much. Storage servers do tend to do stuff to dampen vibration, but then it's a question of storage density. When you've got something like a backblaze pod that's 60 drives in 4U of space. It'd be more unusual to have 60 drives in total in a rack full of normal servers. Now consider 60 drives / 4U, and you'll have multiple of these storage pods in a rack. It adds up.
