The document you referred to https://h20195.www2.hpe.com/v2/getpdf.aspx/4aa4-7060enw.pdf on page 24 (and the "Best Practice" on pg 25), HPE recommends to use a RAID 6 VDG for pools A and B, and use a single SSD drive for read cache for each of those. So there is no tiering recommended for vSphere virtualizaton environments!
I envisage that most buyers of the MSA 2052 would be using it for virtual environments, so would these buyers be better off just buying a 2050 along with it's read cache functionality.
I'd love to hear of some real world users of the 2052 with virtual workloads and what their disk setup is like.
You mentioned "In ideal system you should have Performance, Standard and Archive type of drives", but you must be referring to non-virtual workloads right?
