What does sapmhainstaller do?

Experts:

I see

             HANAAPPINST00_3-20010332.ZIP

             SP00 for SAP HANA MHA INSTALLER 1.1

on SMP and read the related notes for it.

I am not sure what it can do?

I did a google search and it did not yield any info about SAP MHA.

Could you share your knowledge?

Thanks a lot!
