An all-flash storage pool utilizes SSDs as data devices and optional log devices, but does not contain read cache or meta devices. All-flash pools are suitable for virtualization environments or backup workloads.
Before You Begin
Follow the cabling guidelines for all-flash shelves described in Cabinet and Cabling Guidelines in Oracle ZFS Storage Appliance Cabling Guide.
For recommendations on how many drives to select per pool, as well as other considerations and guidelines, see Storage Pool Concepts.
To understand the different data profiles, see Data Profiles for Storage Pools.
If any devices are missing or malfunctioning, make the necessary corrections.

hostname:configuration storage verify> set 1-data=3 2-data=3 1-data = 3 2-data = 3
This example assigns 3 devices from chassis 1 (1-data=3) and 3 devices from chassis 2 (2-data=3) to the pool.
