Re: mainframe = superserver

Thanks for the info. Linux isn't an option, it is windows or
nothing. How about including other vendors than IBM? Does anyone
make what would amount to a windows mainframe? Something that can run
a couple thousand virtual windows servers doing everything from
authentication, file and print, database, web, terminal services,
etc? Maybe something from unisys?

Thanks,
Jack

Hello,

I realize that this has probably been asked before, but google didn't
give me an answer. Before I asked my question let me state that I
know that windows server 2003 and longhorn won't run on an IBM
mainframe. There is the endian issue and the ascii vs ebcidic
issues. Is there a medium to large IBM box that can run a couple
hundred of virtual windows 2003 servers? And said box can scale up to
approximately 1000+ virtual windows servers? Given that all current
servers are dell and hp servers with 2 intel core 2 duo processors and
a total of 150TB of storage?

I am doing research for the possible replacement of 200+ windows
server in our datacenter. We need to add servers, but there is
literally no more power. My thinking is if IBM can get windows
servers to run on their something like their mainframes it would save
electricity and space. Everyone would win.

Thanks,
Jack

zSeries mainframes can NOT run Windows. That I am aware of, IBM is not
even trying. They can run Linux and a LOT of server functions that you
would use Windows for you can also use Linux.

As for the number of Linux images you can get on a zSeries mainframe,
well it depends. Depends on which zBox you get, and what the Windows
servers are doing. If they are all running in a "cluster" attempting to
predict the weather, well, no I don't think even the largest z9 could
handle replacing 200 "four-way" current speed Intel CPU's.

Now if they are all doing things like database serving, e-mail server,
LDAP server, DNS server, ftp server, and file and print server type
functions, then yes one of the zSeries boxes could replace 200.

You may also save in software costs for software that is licensed by the
CPU.
