I’ve met people before who’d rather drink muriatic acid than admit a mistake. I don’t cotton to such folks none too purdy good. This is a post about perfection and imperfection.
Cost Based Optimizer

A question came in about whether it is possible to measure how much data is filtered out when running a query serviced by a Smart Scan in the Exadata Storage Server grid. The following is the long answer.
An Example of SQL Offload Processing Effectiveness Accounting
I’d like to answer this question by taking real information from [...]
In my recent blog post Oracle Exadata Storage Server. Part I., a reader asked:
I wonder if there will be another Appliances with other hardware vendors such as Dell/EMC or SUN?
I’m fairly certain the reader wondered whether the Oracle Exadata Storage Server would be made available on platforms other than HP. However, another reader presumed the [...]
The Pythian Group recently conducted a short podcast interview with me to discuss a few topics related to Oracle Exadata Storage Server and the HP Oracle Database Machine.

This is just a quick blog entry to correct some minor (and some not-so-minor) errors I’ve stumbled upon in blog and Web news media.
Exadata Storage Server Gross Capacity
In his recent Computerworld article, Eric Lai was trying to put some flesh on the bones as it were. It is a good article, but a few bits [...]
As they say, a blog without photographs is simply boring. Here is a picture of a single-rack HP Oracle Database Machine. It is stuffed with 8 nodes for Real Application Clusters and 14 Oracle Exadata Storage Servers with 168 3.5? SAS hard drives. My lab work on a SAS-version of one just like this yields [...]

Bigger Pipes. Infiniband with Remote Direct Memory Access. 5x Faster than Fibre Channel.
More Pipes. Scalable, redundant I/O Fabric.
Yes, it’s called Oracle Exadata Storage Server and it really was worth the wait. I know it is [...]
Where’s Waldo?
As infrequently as I’ve posted over the last few months I’m sort of surprised I even have any readers remaining!
