RE: Oracle to acquire Sun

Well, check this out for a new approach to servers:

I've a funny feeling it may be a niche machine at best.

Subject: RE: Oracle to acquire Sun



Niagara/T2 is horrible for any cpu-intensive, single-threaded
processing, like a large query or update, exp/imp, datapump, etc.  Don't
be fooled by the marketing material.  We were recently burned badly by
trying to migrate a system from old V440 to a new T2000 - performance
was awful.  We ended up moving to Linux on Dell 2950s instead, with just
one quad-core Xeon, and it blows away the T2000.  The T2000 gives you 32
virtual processors/threads, but each process you run is strictly limited
to only one of those threads, and the throughput of that individual
thread is about the same as an old 300MHz CPU.  Oracle even confirms the
same problem in Metalink Note 781763.1.  We just had a lot of discussion
on this very topic a couple months ago - here's the thread for more
detail:

This brings up another topic I've been wondering about - I see a lot of
talk about Oracle on AIX, HP and Sun, but not much at all about Oracle
on Dell and I'm just curious why it seems to be overlooked.  We run
Oracle on just about everything in our data center - AIX, HPUX, Solaris,
Windows & VMS, but lately we've been doing a lot of Oracle Enterprise
Linux on Dell 2950s with quad-core Xeons and the performance and
stability have both been great - for a fraction of the cost of a Sun or
HP x86 box.  Does anyone have a good reason for avoiding Dell or paying
extra for Sun or HP x86 boxes instead?

Why would it not be the Niagara line of processors? T2 runs databases
like a dream and Oracle gives a very nice discount on the cores you have
to license. In many cases that makes for a fantastic ROI on an extremely
potent database server. It is also where SUN put a lot of R/D dollars
over the last few years. T3 or whatever they'll name the next processor
on the same technology ought to further advance the threads and cores
and make it even more fascinating as a computing platform for Oracle.
