Very easy! From the Main Menu, click on Show All (top right corner) to expand the whole menu, under Block Persona, click on Common Provisioning Groups (CPG) and there you'll see the RAID of each array connected to SSMC.

Unlike many RAID arrays, HPE 3PAR physical disks (PD) do not have RAID!

PDs are broken into many many equal-sized pieces called "chunkets". For recent multiple generations of 3PAR, chunklets are all 1GiB.
Each Common Provisioning Group (CPG) specifies a type of disk, a particular RAID, and the data to parity ratio (Set Size). A 3PAR system can have multiple CPGs. When a Virtual Volume (VV) is created, one of its characteristics is which CPG will be used to form it. If snapshots are used, another characteristic is which CPG will be used when creating snapshots. The two CPGs do not have to be the same.

You need to know what the array's CPGs are, then you need to see what CPG each volume uses.

The HPE 3PAR StoreServ Storage Concepts Guide (available at www.hpe.com/info/storage/docs) is worth your time to read.
