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: http://www.raidinc.com/file-storage/gss-ess Also, this is now a "mature"

I'd like to hear about performance consideration from sites that may be using "non-IBM sanctioned" storage hardware or appliance, such as DDN, GSS, ESS (we have all of these). For instance, how could that compare with ESS, which I understand has some sort of "dispersed parity" feature,
