Greenplum uses ZFS
Ok, so it seems that Oracle has a new competitor, that uses... Oracle ZFS:
EMC is getting into the data warehousing / business intelligence (DW/BI) area by buying Greenplum. This takes it into direct competition with Oracle and its Exadata product line.

Greenplum's takeover by EMC is a major victory for open source software, and PostgreSQL in particular. The fact that one of world's largest IT vendors will now be selling software based on PostgreSQL will definitely encourage companies to adopt the database.

IBM got Ilustra decade ago, did that help someone adopt Postgres?
I fail to see how you benefit when someone steal your code and make money, giving nothing back in return. It is fine if you like to give to big companies, but don't paint it like you got something. EMC is going to compete with Postgres, not help it.
