		<description><![CDATA[Hi Phil,

As Program Director for database software at IBM, I closely track my primary competitors.  Its only natural that I would.  And when the occasion warrants it, I provide my perspective on Oracle claims.  I think its healthy for both sides of any story to be told.  In this specific instance, I found these developments to be interesting, and I knew that many readers of this blog would too.

I agree that we will have to wait until the end of the fiscal year to see if Oracle hit their revised estimates.  Who knows, they may even exceed them.  We&#039;ll see in a few months.  But nonetheless, I still think it interesting to see the significant downward trend in expectation-setting by Ellison and Oracle.  Perhaps they are reacting to their recent poor financial reportings, and playing it safe with their expectation setting.  Again, we&#039;ll see soon.

If we want to cut through the noise being made on earnings calls and the obtuse references to &quot;sales&quot; and &quot;installations&quot;, we should probably look at server share as reported by independent third party analyst firms.

Regards,
Conor.]]></description>

		<description><![CDATA[Conor,
Its nice that you are pointing out the fact that you are tracking Exadata sales so closely. You must be either concerned or amazed by the figures.  Haven&#039;t seen anyone from Oracle blog about Power 795, Netezza or Watson system sales so well but maybe its because IBM doesn’t report out unit #&#039;s like Oracle does, If IBM doesn’t report out expected unit growth, it could never be wrong.  Reporting revenue #&#039;s instead of unit #&#039;s can be really misleading - if you increase system costs, increase margin (lower discounts), you can have unit volume decreases while still showing revenue growth.

But, here, you are mixing actuals versus predictions/forecasts. As you state &quot;In June of last year, during Oracle’s FYQ4 2011 earnings call, Larry Ellison claimed that Oracle expect more than 2,000 Exadata systems to be installed in fiscal year 2012&quot;. Well, FY2012 isn&#039;t over yet so you&#039;ll have to see whats reported after May 2012. 

Till then, its all speculation and not worth the grains of salt remaining on the table.  What I find more interesting is that while Oracle is indeed showing great growth on Exadata/ Exalogic / SPARC SuperCluster, theres no reports from IBM to the contrary. So how are those Netezza, Power 795 or Watson sales going? And last I saw, IBM didn’t do so well on Mainframes during Q4 with a 31% drop in revenue http://bit.ly/Ako0Z7. Not a good sign when Q4 is IBM&#039;s strongest quarter.]]></description>

		<description><![CDATA[Conor and Greg - you&#039;ve both done a great job probing and clarifying the numbers. It would be great to see each of you, on your respective blogs, now post a new piece that lays out the details you fleshed out clearly. What we have now is a great thread that has to be read serially to get the point. You&#039;ve punctured a few of each other&#039;s claims - in an admirably courteous way - and reinforced others. I&#039;d love to see each of your takes on the net effect of the discussion.]]></description>

		<description><![CDATA[When I make purchasing decisions, I look at more than the benchmarking hype that is generated. I can twist any benchmark result to hype it and make it seem like &quot;we are leading the industry.&quot; Surprised nobody went after the TPMC per thread, TPMC per Watt or TPMC per gHZ claims.

Most of the benchmarks do not provide you with any indication of TCA, TCO, reliability, up-time and so on. And, as far as I know, POWER is one of the few that actually use server virtualization as part of their benchmarking process. In today&#039;s environment, server virtualization should be considered a key component of any benchmark that is submitted.

Something that I think is a more important and distinguishing difference between x86, SPARC, Itanium, POWER and the z Architecture actually comes from HP&#039;s Odyssey announcement http://h18004.www1.hp.com/products/solutions/mcci/index.html. If you read between the lines, HP is saying that x86, Windows on x86 and Linux on x86 are not mission critical, do not have the RAS required to run a business and cannot meet business required SLA&#039;s in their current state. 

When I read the announcement, I was just shaking my head. Ouch to trusted partners Microsoft, Red Hat and Intel.]]></description>

		<description><![CDATA[&lt;blockquote&gt;The IBM configuration focused their spending on the servers, whereas the Cisco/Oracle configuration focused their spending on the storage. And the difference is huge. When I get some time, I must dig a little deeper into this to understand the system characteristics…
&lt;/blockquote&gt;

Once you analyze the FDR you will realize that statement is not as true as you would first be led to believe.  TPC breaks pricing into &quot;server&quot; and &quot;storage&quot; but if the storage is actually internal it falls into the &quot;server&quot; pricing, if it is external then it falls into the &quot;storage&quot; category.  In the IBM case the SSDs were part of the &quot;server&quot; category since they are in the I/O Drawers, whereas the Cisco/Oracle result they used Violin storage which falls into the &quot;external&quot; category.]]></description>
