XtremeData update
I talked with Geno Valente of XtremeData tonight. Highlights included:
- XtremeData still hasn’t sold any dbX stuff (they’ve had a side business in generic FPGA-based boards paying the bills for years). Well, there may have been some paid POCs (proofs of concept) or something, but real sales haven’t come through yet.
- XtremeData does have three prospects who have said “Yes”, and expects one order to come through this month.
- XtremeData continues to believe it shines when:
- Data models are complex
- In particular, there are complex joins
- In particular, two large tables have to be joined with each other, under circumstances where no product can avoid doing vast data redistribution
- XtremeData insists that all the nice things Bill Inmon – including in webinars — has said about it has not been for pay or other similar business compensation. That’s quite unusual.
- XtremeData is coming out with a new product, codenamed the Personal Data Warehouse (PDW), which:
- Is ready to go into beta test
- Should be launched in a month and a half or so
- Will have a different name when it is launched

February 2010 data warehouse DBMS news roundup
February is usually a busy month for data warehouse DBMS product releases, product announcements, and other real or contrived data warehouse DBMS news, and it can get pretty confusing trying to keep those categories of “news” apart.* This year is no exception, although several vendors – including Teradata and Netezza – are taking “rolling thunder” approaches, doing some of their announcements this month while holding others back for March or April.
*I probably have it worse than most people in that regard, because my clients run tentative feature lists and announcement schedules by me well in advance, which may get changed multiple times before the final dates roll around. I also occasionally miss some detail, if it wasn’t in a pre-briefing but gets added at the end.
Anyhow, the three big themes of this month’s announcements are probably:
- Integrating different kinds of analytic processing into databases and DBMS.
- Taking advantage of hardware advances.
- Playing catchup in areas where small vendors’ products weren’t mature yet.

TwinFin(i) – Netezza’s version of a parallel analytic platform
Much like Aster Data did in Aster 4.0 and now Aster 4.5, Netezza is announcing a general parallel big data analytic platform strategy. It is called Netezza TwinFin(i), it is a chargeable option for the Netezza TwinFin appliance, and many announced details are on the vague side, with Netezza promising more clarity at or before its Enzee Universe conference in June. At a high level, the Aster and Netezza approaches compare/contrast as follows: Read more

Intelligent Enterprise’s Editors’/Editor’s Choice list for 2010
As he has before, Intelligent Enterprise Editor Doug Henschen
- Personally selected annual lists of 12 “Most influential” companies and 36 “Companies to watch” in analytics- and database-related sectors.
- Made it clear that these are his personal selections.
- Nonetheless has called it an Editors’ Choice list, rather than Editor’s Choice.
(Actually, he’s really called it an “award.”)
Comments on the Gartner 2009/2010 Data Warehouse Database Management System Magic Quadrant
At intervals of little over a year, Gartner Group publishes a Data Warehouse Database Management System Magic Quadrant. Gartner’s 2009 data warehouse DBMS Magic Quadrant — actually, January 2010 — is now out.* For many reasons, including those I noted in my comments on Gartner’s 2008 Data Warehouse DBMS Magic Quadrant, the Gartner quadrant pictures are a bad use of good research. Rather than rehash that this year, I’ll merely call out some points in the surrounding commentary that I find interesting or just plain strange. Read more
Netezza Skimmer
As I previously complained, last week wasn’t a very convenient time for me to have briefings. So when Netezza emailed to say it would release its new entry-level Skimmer appliance this morning, while I asked for and got a Friday afternoon briefing, I kept it quick and basic.
That said, highlights of my Netezza Skimmer briefing included:
- In essence, Netezza Skimmer is 1/3 of Netezza’s previously smallest appliance, for 1/3 the price.
- I.e., Netezza Skimmer has 1 S-blade and 9 disks, vs. 3 S-blades and 24 disks on the Netezza TwinFin 3.
- With 1 disk reserved as a hot spare, that boils down to a 1:1:1 ratio among CPU cores, FPGA cores, and 1-terabyte disks on Netezza skimmer. The same could pretty much be said of Netezza TwinFin, the occasional hot-spare disk notwithstanding.
- Netezza Skimmer costs $125K.
- With 2.8 or so TB of space for user data before compression, that’s right in line with the Netezza price point of slightly <$20K/terabyte of user data.
- That assumes Netezza’s usual 2.25X compression. I forgot to ask when 4X compression was actually being shipped.
- I forgot to ask, but it seems obvious that Netezza Skimmer uses identical or substantially similar components to Netezza TwinFin’s.
- Netezza Skimmer is 7 rack units high.
- In place of the SMP hosts on TwinFin Systems, Netezza Skimmer has a host blade.
- Netezza (specifically Phil Francisco) mentioned that when Kalido uses Netezza Skimmer for its appliance, there will be an additional host computer, but when it uses TwinFin for the same software, the built-in host will suffice. (Even so, I suspect it might be too strong to say that Skimmer’s built-in host computer is underpowered.)
- Netezza also suggested that more appliance OEMs are coming down the pike specifically focused on the affordable Skimmer.

Reports of perfectly-balanced hardware configurations are greatly exaggerated
Data warehouse appliance and software appliance vendors like to claim that they’ve worked out just the right hardware configuration(s), and that a single configuration is correct for a fairly broad range of workloads. But there are a lot of reasons to be dubious about that. Specific vendor evidence includes:
- Teradata ascribes considerable importance to a Virtual Storage technology whose main purpose is to allow mixing of heterogeneous storage devices in a single system. And the discussion rarely suggests that these parts will be in a rigid fixed relationship.
- Netezza — as Teradata keeps reminding me — often sells boxes with the expectation that they won’t be filled with data, so as to increase spindle count and hence performance.
- Oracle/Sun have dropped some comments about Exadata being more flexibly configured going forward.
- Kickfire’s new “high-end” appliance lets you attach fairly arbitrary amounts of external storage.
- And of course, software-only analytic DBMS vendors run their software in all sorts of hardware and storage environments.
What’s more, the claim never made a lot of sense anyway. With the rarest of exceptions, even a single data warehouse’s workload will contain different queries that strain different parts of the system in different ratios. Calculating the “ideal” hardware configuration for that single workload would be forbiddingly difficult. And even if one could calculate it, it almost surely would be different than another user’s “ideal” configuration. How a single hardware configuration can be “ideally balanced” for a broad class of use cases boggles the imagination.

Oracle Exadata 2 capacity pricing
Summary of Oracle Exadata 2 capacity pricing
Analyzing Oracle Exadata pricing is always harder than one would first think. But I’ve finally gotten around to doing an Oracle Exadata 2 pricing spreadsheet. The main takeaways are:
- If we believe Oracle’s claims of 10X compression, Exadata 2 costs more per terabyte of user data than Netezza TwinFin — $22-26K/TB vs. TwinFin’s <$20K — but less than the Teradata 2550.
- These figures are highly sensitive to assumptions about Oracle’s hybrid columnar compression.
- Similarly, if Netezza or Teradata were to significantly upgrade their own compression, the price comparison would look quite different.
- Options such as Data Mining or Oracle Spatial add 12% or so each to Exadata’s total system price.
Longer version
When Oracle introduced Exadata last year it was, well, expensive. Exadata 2 has now been announced, and it is significantly cheaper than Exadata 1 per terabyte of user data, based on:
- Similar overall pricing
- Twice the disk capacity
- Better compression

Facts and rumors
- Vertica is putting out a press release today touting its 100th customer, and talking of triple digit growth last year.
- Multiple sources have told me that the DATAllegro system is being thrown out of Dell, so evidently Dell is telling this to one and all. If that goes through, this would presumably leave TEOCO as DATAllegro’s single happy customer. (I haven’t checked with Microsoft for its view.)
- A rumor has it that Infiniband technology vendor Voltaire, Ltd. privately claims triple-digit sales of switches for Exadata 1 (I think that one would be one switch per Exadata installation, not per rack). Based just on a quick glance, this is far from confirmed by Voltaire’s earnings conference call transcripts or SEC filings. However, the most recent transcript does seem to indicate Voltaire got multiple Exadata deals in the telecommunications sector, and suggests some Exadata penetration in other sectors as well.
- I was told of a classified-agency user that has >1 petabyte of data on Exadata 1 and 600 terabytes or so on Netezza. My not-obviously-biased source says the agency is distinctly happier with Netezza than Exadata.
- Like ParAccel, Oracle just got dinged for TPC-related misbehavior.
- Rumor has it that Sun has no intention of helping ParAccel rerun its withdrawn TPC-H benchmark.
- ParAccel has withdrawn the claim from its home page to be the “CERTIFIED” price-performance leader. This seems to confirm that the claim was a reference to the TPC-H. In my opinion, that was a gross misrepresentation of what the TPC-H shows.
What Nielsen really uses in data warehousing DBMS
In its latest earnings call, Oracle made a reference to The Nielsen Company that was — to put it politely — rather confusing. I just plopped down in a chair next to Greg Goff, who evidently runs data warehousing at Nielsen, and had a quick chat. Here’s the real story.
- The Nielsen Company has over half a petabyte of data on Netezza in the US. This installation is growing.
- The Nielsen Company indeed has 45 terabytes or whatever of data on Oracle in its European (Customer) Information Factory. This is not particularly growing. Nielsen’s Oracle data warehouse has been built up over the past 9 years. It’s not new. It’s certainly not on Exadata, nor planned to move to Exadata.
- These are not single-instance databases. Nielsen’s biggest single Netezza database is 20 terabytes or so of user data, and its biggest single Oracle database is 10 terabytes or so.
- Much (most?) of the rest of the installations are customer data marts and the like, based in each case on the “big” central database. (That’s actually a classic data mart use case.) Greg said that Netezza’s capabilities to spin out those databases seemed pretty good.
- That 10 terabyte Oracle data warehouse instance requires a lot of partitioning effort and so on in the usual way.
- Nielsen has no immediate plans to replace Oracle with Netezza.
- Nielsen actually has 800 terabytes or so of Netezza equipment. Some of that is kept more lightly loaded, for performance.
