They describe real-world load and I/O experience, NOT hardware maximum-capability specifications or advertised limits: IOPS and throughput are each server's highest reading of the last 60 days (each reading a two-minute average), service time is measured I/O latency, disk utilization is the share of time disks were busy servicing I/O (iostat %util) -- not a percentage of hardware capacity. No totals, server counts, or absolute capacity are published, by design.
