new technology to combine the c/s &mainframe ??

By CrazyGril ·
can we find technology that glue the client/server & maineframe by combining their advanteges (the powerful storage of mainframe plus the flexability,scalability and speed of the client/server ?...

Yes we can

Ahhh the Mainframe.

Years and years ago, when PCs ran on slow processors, the Mainframe was a mythical land where computing power seemed to be unlimited and disk storage seemed to be bullet-proof, unsinkable, and limitless.

Not any more.

For all intents and purposes, the mainframe is dead. You can buy 'mainframe technology' for any platform.

The mainframe today is really nothing more than an alternate OS choice, and the modern mainframe can runs UNIX and even Linux under logical partitions, while using disk subsystems and distributed processing such that it can walk and talk just like any client-server system.

So, for all intents and purposes, you can run an IBM mainframe running 2000 Linux virtual machines, or you can run a cluster of Intel VMWare servers running 2000 Linux virtual machines. Either can interface to a redundant Hitachi Storage Area Network for high-availability storage and connect to the network via multiple GigE interfaces.

In the end, it's more of a cost calculation than the technology decision.

Huh ?

by Tony Hopkinson In reply to new technology to combine ...

Client server is an application design architecture, it has nothing to do with hardware as such.

An example , there was a DEC mini you could buy that could take and handle 128 network cards.
Now you'd cluster 128 machines with 1 network card each....

If DEC were still knocking them out with modern tech it would outperform the cluster. But it would be expensive and give a single and HUGE point of failure.
Even more to the point you might not need 128 nodes ever, or hardly ever, or may be you need more, which is where buying say a blade rack and then plugging more in there as you grow, is far more economically viable.

Lots of people do client server with mainframes and mini's, mainly though because they were already there, with a lot of inhouse software running on them.
Essentially it's a choice between a few pieces of rock solid kit, or a lot of more flakey ones and planned redundancy if anyone of them fails.
I've seen mainframes and minis up and stay up for years. In fact one of the riskiest things you can do is turn them off on account of no one knows if they will come back up and teh guy who set them up died after retiring.
