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.

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)
