Sun partners with Greenplum to launch open source data warehouse appliance

Ed Sim of Dawntreader Ventures let me know about this (Greenplum is a portfolio company). The product referenced below is "Bizgres MPP" which Greenplum describes as PostgreSQL for Data Warehousing. They market another product "Bizgres" as PostgreSQL for Business Intelligence. My sense is that Greenplum plays in a similar space as Netezza, DATAllegro and even SAP's BI accelerator product.

Sun Microsystems and open-source database maker Greenplum, July 26 introduced a data warehouse appliance built from open-source software and general purpose systems that the companies claim is much faster and cheaper than comparable proprietary systems...Called simply the Data Warehouse Appliance, the new product is powered by Greenplum's own distribution of the open-source PostgreSQL database, Bizgres MPP and Sun's open-source Solaris 10 operating system.

ZDnet's Open Source blog has this as well:
Open source compresses data warehouse margins by ZDNet's Dana Blankenhorn -- The knock on open source databases has always been that it doesn't scale. With this new offering, users can scale from a few megabytes to multiple terabytes, without changing the underlying database structure.
