Is it redundant to allocate L2 cache for an SSD drive

Support,
I am using Primo cache with a combination of SSD storage drives and a large 4 TB mirror raid drives. I'm noticing when they share tasks with L1 and L2 cache, that the cache apparently is active when I request data from another SSD drive. So it appears that PrimoCache is using SSD space in the L2 cache to cache SSD data. Is this really happening? It seems redundant.
If this is true then it seems that I should the only allocate L1 memory for my SSDs. Should I allocate L1 and L2 cache space for a 4TB spinning hard drive. Or should I rather just use L2 [SSD] cash for my physical hard drive?
