Sun Solaris, OpenSolaris Due to me not working for OSNews these past eight weeks, I've been a bit out of the loop, as I didn't really follow technology news. I did notice that a lot is going on in OpenSolaris land, and today, Oracle has outlined what it has planned for Solaris 11 - and according to some, the fears about OpenSolaris' future were justified.

It is not POWER. Mainframes don't use POWER, they use s390x a.k.a z/Architecture. And specialty engines are not required to run Java or Linux. They run just fine on general purpose mainframe engine. Thing is, specialty engines are cheaper, but they have certain instructions disabled. So you can't run z/OS on Linux specialty engine, or on Java specialty engine. But they run Java and Linux same as GP engine and have bigger bang for a buck since they are cheaper. For z/OS you have to buy most expensive engines. Here is more about mainframes.

New mainframes which are coming out this year will use POWER CPUs too, but only as accelerators. Main CPUs will only use s390x.

And about lockin... I know CIOs who got into mainframe game. Believe me, they are not happy. They curse the day they thought about Mainframe if they are ones who made the decision, and those who are inherited that state the union are cursing whichever CIO come up with idea to sell company to IBMslavery.

Good CIOs don't lock-in. Ones who experienced it, hate it. They will accept it sometimes when they perceive there is no better choice, or when they fail to see lock-in trap in plain sight (this is how Microsoft gets its customers: through deception. They say: it is widely used "industry standard" and some people think that means "no-lockin"). Most regret when they see that they put their head in the noose. Then they make efforts to reinvent their whole IT infrastructure and move to open source. But it is hard. It is not called lock-in for nothing.

Free Software looks like some strange ideology at fist, but when you get burned repeatedly by money grabbing proprietary companies, Stallman's ideology starts to make very practical sense and all the sudden starts looking very pragmatic.

From the IBM website:

"The zEnterprise 196 each MCM features six 5.2 GHz Quad Core processor chips" (up to 4 processor books, each containing an MCM)

I assumed they were POWER7 chips

Of course System Z mainframe has also general purpose CPU which coordinates the task distribution.

Anyway if IBM uses mix of different chips in their mainframes, HP atleast is dedicated to Intel Itanium chips that not many find a use for ;) Actually HP Superdone2 seems just a rack of small computers, each containing CPU and memory.

It doesnt matter which CPUs IBM Mainframes use. The Mainframes lag behind cpu wise. They are dog slooooow. As I have shown earlier with links and calculations, you need a PC with 8-way Intel Nehalem-EX cpus, to match the biggest IBM Mainframe with 64 cpus. That is horribly bad performance from the Mainframe. In fact, you can emulate a Mainframe on your laptop with "Herkules".

But the biggest IBM Mainframe with 64 cpus, probably costs a couple of 10s of million USD.

If someone asks me, I can show these links and calculations again. Please, someone ask me to start over again about how slow the Mainframe cpus are. :o)
