Randomly coming across stuff on Twitter I didn't know was going on it appears UK based infrastructure software company Clearpace brought in a Gen4 Centera and attached their NParchive data pump.
From their blog post on the topic here's the money shot..
The headline is that across the board, NParchive on Centera proved to be as efficient as NParchive on DAS/NAS/SAN, importing up to 13B records/day on a single 8 core server while providing excellent query performance. In terms of scale up, NParchve on EMC Centera also really shines — near perfect scalability for both query and import across multiple servers, with no sign of slowing down. When comparing query performance against a well known OLTP database using local storage, the results were broadly similar, ranging from a 2X slowdown to a 10X speedup.
