Is STRASPBAL the command to manage/move hot/cold data, P7 V7R1, with internal disks similar to Easy Tier

1) Is STRASPBAL the command to manage/move hot/cold data, P7 V7R1, with internal disks similar to Easy Tier?
2) What is the difference between STRASPBAL HSM (Hierarchical Storage Management) and STRASPBAL MP (Media Preference), end results appear to be the same?
3) Can very large PF and LF be both hot and cold data? In other words, the old data which may not be accessed be cold data?
4) Does this also apply to IFS data?
5) Does STRASPBAL need to be constantly running?
6) Does anyone have a SSD/HDD mixture and using STRASPBAL?

I currently have 100% SSD, but cost of adding disk is having me look at a SSD/HDD mixed alternative solution.

Thank You
