But c'mon. The 10th largest database in that survey was under 18 TB of user data. Do you seriously believe that all of eBay, Wal-Mart, Sears, Bank of America, or Chase were under 18 TB at the time of the survey? Do you seriously believe that any of them were under 18 TB? Do you seriously believe that any of them were under 50 TB? CAM Edit: Wait. I just looked at the survey, and you're talking about more than user data -- indices and aggregates as well. And you still got numbers that low. Wow. Richard,

The opinions on modular expansion and resilience were made over several months of involvement with Oracle in the benchmark tests and with Oracle customers who had participated in the beta program. The WinterCorp studies on database size, which have been conducted every few years since 1995, are open to all users. The data is vigorously validated by WinterCorp approved scripts run by each user and reviewed by WinterCorp tech staff. The process is the same regardless of vendor. We separately measure user data, indexes, summaries, free space and work space. The 100 TB database you mention in your article was measured to contain 89 TB of user data. The data, as noted on our website,was accurate as of September, 2005, when the survey closed. We look forward to providing updated data, and when it is available, it will be published. If you heard of larger databases at that time, chances are that you heard a figure based on total disk, not data.

I missed that. When I do a sponsored paper, there's a big vendor logo on the front page, and one or more paragraphs disclosing the the sponsorship. I guess that dulled my reading skills with respect to Winter Corp's more subtle disclosure. Sorry. CAM Thanks, Ken. I missed that.

Just one comment ... there is nothing sneaky or underhanded herer and there is no lack of clarity regarding disclosure in the Winter Report. I thought I would mention this, since the bulk of your commentary is not about the findings of the report or the technical merits of Exadata and thus leaves the wrong impression. The second paragraph of the executive summary reads ... "This paper presents the results of the first independently validated tests of the performance of Exadata for data warehousing. Winter Corp, an industry expert in large scale data management, was retained by Oracle to review the design of the tests; audit the test process; analyze the results; and, provide an independent technical assessment of the product." In case you don't see it on second reading, it says, "Winter Corp ... was retained by Oracle". Nuff said. Ken Hi Curt.

Nuff said.
