HP MSA 2040 Perf Auto Tiering LTU
Paper (physical) license MSA 2040 Performance Auto Tiering
Before firmware GL200 tiering was possible only by manual creation. Tiering needed careful planning applications that required the highest performance, were placed on a tier made up of SSDs. Applications with lower output were placed on Tier generated from Enterprise SAS drives.
From firmware GL 200 or later, MSA 2040 supports automated tiering.

Performance first tier of SSDs - part of this license
Frequently accessed to the data are automatically moved to the fastest SSD tier (layer)
Standard second tier with SAS Enterprise SAS HDD - part of this license
Here they are placed applications with lower output.
Archive third tier benefit Midline SAS HDD - works without charge within the GL200 firmware or later
Not very often accessed to the data is automatically transferred to the layer with the lowest performance.
