7% is the recommended minimum amount of Flash that a technical architect should specify when designing a Dell Unity XT 480 using the System Designer option of Sizer.

"The engineer should design a system to handle all, or nearly all, IOPS in one particular tier"

When sizing a Dell Unity XT 480F using the System Design method, you can select one of four workload types and Drive count and RAID level. This workload type selection will take into account the specific IOPS and capacity requirements of the environment. The drive count and RAID level will determine the overall capacity and level of data protection required.
