IBM came up with HACMP for AIX in the early 90's.

Linux got DLM and cluster file system (GFS) in the early 00's.

In the mean time the industry moved into another direction.
Application clusters instead of OS clusters.

So instead of having:
- applications X and Y on OS A using foo cluster software
- applications X and Y on OS B using bar cluster software
it was:
- application X using foo cluster software on OS A and B
- application Y using bar cluster software on OS A and B
