SPA IO/s question
Please help me understand this.
I have one server doing a large restore to a vMax and it's the only thing running on the array. In SPA, Host IO/s shows ~1,200 which agrees with PowerPath numbers on the host. What I don't understand is FE Reqs/sec which shows ~8,000. and under Snapshot the storage group for this host shows writes per second at ~4,000.
Why don't these numbers match up?

Requests are for 64k cache slots, so one 128k host IO is going to be at least 2 requests.

So can you check the IO size and confirm?
