• Teradata execs wondered if the device has a mixed architecture, with a shared-nothing approach on the Exadata Storage Server side (for fast, massively parallel processing) but a shared architecture on the Database Machine side? If so, the database optimizer has to be very sophisticated to maintain performance.
• Oracle says the HP Oracle Exadata Storage Servers deliver "10x or more performance improvements in data-intensive query processing," but the question is, 10 times what exactly? Are benchmarks available?
• One question just for HP: How do you reconcile the HP-Oracle device with HP's Neoview offering? Isn't that a competitive overlap?
Interviews with Oracle and HP are pending, so I'm hoping to share answers by Monday. On the competitive front, IBM has declined to comment on the announcement.The whole concept of the data warehouse appliances has gone from "an interesting niche in the market to something that's smack dab in the middle of the mainstream market." That's how Jim Baum, president and COO of Netezza, sized up the HP Oracle Database Machine announced earlier this week, but it's clear that competitors, as well as analysts and potential customers, are still struggling to size up the actual product.
