Flash-based data warehousing is getting ever closer
EMC is rolling out solid-state drives later this quarter. The press release mentions the word “terabyte”, so this is for non-trivial systems. And by the way, 100,000 write/erase cycles before something wears out is several per hour, so that’s a non-problem for data warehousing.
ParAccel and SAP already offer RAM-based appliances. I suspect we’ll see appliances based on solid-state drives before long. I also wouldn’t be shocked if a non-appliance vendor such as Oracle suddenly jumped into this area, trying to use it as a way to leapfrog the appliance vendors.

Intelligent Enterprise’s list of 12/36/48 vendors
I’m getting a flood of press releases today, because many of the companies I write about were selected to Intelligent Enterprise’s list of 12 most influential vendors plus 36 more to watch in the areas Intelligent Enterprise covers (which seems to be pretty much the analytics-related parts of what I write about here and on Text Technologies). It looks like a pretty reasonable list, although I think they forced the issue in some of the small analytics vendors they selected, and of course anybody can quibble with some of the omissions.
Among the companies they cited, you can find topical categories here for IBM (and Cognos), Informatica, Microsoft, Netezza, Oracle, SAP/Business Objects (both), SAS, and Teradata; QlikTech; Cast Iron, Coral8, DATAllegro, HP, ParAccel, and StreamBase; and Software AG. On Text Technologies you’ll find categories for some of the same vendors, plus Attensity, Clarabridge, and Google. There also are categories for some of these vendors on the Monash Report.
Netezza targets 1 petabyte
Netezza is promising petabyte-scale appliances later this year, up from 100 terabytes. That’s user data (I checked), and assumes 2-3X compression, or a little less than they think is actually likely. I.e., they’re describing their capacity in the same kinds of terms other responsible vendors do. They haven’t actually built and tested any 1 petabyte systems internally yet, but they’ve gone over 100 terabytes.
Basically, this leaves Netezza’s high-end capability about 10X below Teradata’s. On the other hand, it should leave them capable of handling pretty much every Teradata database in existence. Read more

The world according to Derek Rodner of EnterpriseDB
If you’re interested in the world of mid-range, OLTP, and/or open source database management systems, Derek Rodner’s blog is worth checking out. His 2007 Year in Review post deserves a look — even though it’s about as unbiased and spin-free as Bill O’Reilly’s TV show, in that combines multiple shots each at Oracle and MySQL with some plugs for EnterpriseDB. I’ve already praised his post a month ago listing large numbers of EnterpriseDB successes. Of course there are multiple heartfelt arguments on behalf of Postgres (too many to link to specifically). And he even has a great set of tips — which I hereby recommend to all my vendor clients — on how best to use Google AdWords.

DBMS2 should now be trojan-free, the feeds should work too, and so should my email
On New Year’s Eve, I got the impression there might be trojans being served up on monash.com. New Year’s Day, Melissa Bradshaw confirmed that there were indeed trojans on both monash.com and dbms2.com. My web hosting company tracked this problem down into the server OS, and recompiled it last night. The resulting planned outage caused our FeedBlitz-based email feed to include broken links.
The malware appears to have been inserted during a Christmas Eve mailbombing, so I can’t be sure how soon trojans first appeared. What I CAN be sure of is that some of my email was lost forever, and that other mail was sent back with bounce messages.
Needless, to say, this has not been fun. And I am very apologetic to any of you who have been inconvenienced. I’d offer you all a refund — but the blogs are already free. 🙂 So the best I can do is try to have great posts going forward, making it worth your while to keep reading here.
At this point, I am optimistic that the technical problems are behind us. My sites are up. My email is working. I’ll be shocked if the feeds don’t work.
