I like it when people tell you "the facts, and just the facts".
That is why it is refreshing to read Jeff Browings' blog entry's on storage. Today, I noticed that he clearly described the current fad of 'Thin provisioning" in an Oracle environment. Link
"This makes thin provisioning completely useless nonsense for Oracle data. Anyone who tells you otherwise should be viewed with deep suspicion. I say this without any bias whatsoever, since my employer sells arrays that provide thin provisioning too. I am simply telling you the way it is here."
The trade press just regurgitates the press releases provided by the storage manufacturers, and does not seem to challenge the assumptions that the manufacturers make very often. Let's give people the facts and let them make rational decisions on their strategic storage purchases.
