Norris-Oracle Jun 29, 4: The Oracle team knows more about the configuration than the customer who has been delivred the exadata machine does?
According to my blog statistics, a good number of new readers find my blog by being referred to this page by google. The original blog post follows: I expected Oracle Exadata Storage Server to make an instant splash, but the blogosphere has really taken off like a rocket with the topic.
Unfortunately there is already quite a bit of misinformation out there. So consider this installment number one. What does the word programmable mean in the product name Exadata Programmable Storage Server? I have seen this moniker misapplied to the product. Well, it is of course to the Exadata product development organization, but there is nothing programmable for the field.
I think, perhaps, someone may have thought that Exadata is a field programmable gate array FPGA approach to solving the problem of offloading query intelligence to storage. How can Exadata be so powerful if there is only a single 1gb path from the storage cells to the switch?
I saw this on a blog post today and it is an incorrect assertion. This is just a common notation blunder. How does Exadata change the SGA caching dynamic? Everything that is cached today in the SGA will still be cached.
Most Exadata reads are buffered in the PGA since the plan is generally a full scan. That is not to say that there is no Exadata value for indexes, because there can be.
Yes, and the question is what? Of course concurrent queries attacking the same physical disks will introduce seek times and rotational delays. If Exadata is servicing concurrent queries that attack different regions of the same drives then, yes, by all means there will be seeks.
Exadata leverages ASM normal redundancy mirroring which mirrors and stripes the data.
Misinformation will be propagated. Let me see if I can handle this topic in a different manner. In the end, I personally think the demonstrated throughput is more interesting than an academic argument one might stumble upon in an anti-Exadata positioning paper.Oracle Exadata Database Machine system architecture.
There are several software enhancements to Oracle Linux, Oracle RAC, and the Oracle Exadata Storage Server software to remove I/O bottlenecks and enable the extreme performance improvement delivered by this engineered system.
