IBM ESS, GSS, GNR, and Perseus refer to the same "declustered" IBM 
raid-in-software technology with advanced striping and error recovery.

I just googled some of those terms and hit this not written by IBM 
summary:

Also, this is now a "mature" technology. IBM has been doing this since 
before 2008.  See pages 9 and 10 of:
