New Linux on mainframe
We are about to start exploring the possibility of a Solaris and Linux
consolidation onto a new mainframe.

My current take on it is that it has a HORRIBLE price performance
ratio, but I could be wrong.

Anybody got any questions they want me to pursue concerning this,
since I'll probably have access to some serious big iron equipment
to test?
New solaris on a mainframe? What breed?
As far as linux on mainframes go my (very poor) understanding is that a virtual machine is spawned to load an OS and the underpining frame stuff keeps all the memory and peripheral access separate for each virtual machine. I havnt heard of solaris on a mainframe but would be interested.
thanx,

New Sounds like great big fun

New It's a scam
Or so I think. I'll know more in a couple
of weeks when I get an account on one to play.

I never said Solaris on MF, I said we might
be consolidating a bunch of stuff from Linux
and Solaris boxes on a Linux partition on
the MF.

Here's da deal. I use 2 Sun 450s per client,
along with a 2TB Fibre based array, which
has 4 FC connection. I also use 2 to 4 Linux
compute servers.

Rather than deal with all that for each client,
wouldn't it be nice if we could buy a big
box MF to take care of it for lots of client.

But it's a total crock'o'shit. The MF would cost
at least 1,000,000, and I'd need to add disk
for each client anyway. The performance would
SUCK. I'd only get 1 (ya here that, 1!!!!)
piece of shit MF CPU. The disk IO would be
the same as we currently have, which is MAX about
80MB per second, with single file access hitting
about 10MB per second, as opposed to 300MB per
dual Sun/Xyratex array, and my IO gains every time
I add a client.

In order for me to hope to achive the performane
of $70,000 worth of Sun gear and $100,000 worth of
disk, I'd have to spend about $3,000,000 on the
MF. It would be INSANE!!!!!

So, I'll pitch my alternative:
[link|http://store.sun.com/catalog/doc/BrowsePage.jhtml?catid=61163|http://store.sun.co...?catid=61163]

It's only $600,000. Cough cough.
It's got 12 CPUs (each twice as fast as current 450 CPUs)
and can grow to 24 CPUs. I assume each CPU added would be
about $5,000, so add $60,000, for a total of $660,000.
Which would be the equivelant of 48 450 cpus, which means
it will equal about 16 450s in power. Since each 450
costs me about $35,000, I've LOST money since 16 450s
will cost $525,000. But it is a LOT easier to manage
a single box, right? Also, since the 450s, aren't truly
utilized 100% of the time, they are wasted cycles since
I don't share them between clients. But peak performance
is important, since user wait time is the real measure of
performance, not total throughput. So individual peak
time would be GREAT, which would be a win, unless all clients
hit at once, which should allow at least decent performance,
because I wouldn't attempt to add more than a client per
2 CPUs. Except the perceived performance would SUCK for people
who are used to going solo but sometimes they start fighting
others. So I would artificially limit and given query
(except my own of course) to just a couple of CPUs anyway.


ARRGG!!!
I dunno.
New Dunno me I like distributed
I would get rack mounted netra 420R with attendant disk arrays but I never was muvh for consolidation. The box looks pretty nifty, could play becoup redneck rampage with 12 750's.
thanx,
bill
why did god give us a talleywhacker and a trigger finger if he didnt want us to use them?

New Bloomberg: IBM sells 1000th zSeries 'frame
[link|http://quote.bloomberg.com/fgcgi.cgi?ptitle=Technology%20News&s1=blk&tp=ad_topright_tech&T=markets_bfgcgi_content99.ht&s2=ad_right1_technology&bt=ad_position1_technology&middle=ad_frame2_technology&s=AO66xcRTxSUJNIFNl|Here].

Cost, Savings

IBM's mainframes typically cost more than $1 million, with the price rising as customers add features. Unix-based Web servers start at several thousand dollars and cost as much as several hundred thousand dollars. Consolidating server farms reduces the cost of personnel to manage the servers, the floor space to house the devices and the power needed to run them and associated air-conditioning, Mastrobattista said.

While many customers use mainframes for processing various types of transactions, some have been attracted by the inexpensive Linux operating system and the ability of mainframe operators to partition the machines, Mastrobattista said.

Entire server farms running corporate Web sites, file servers and the like can be consolidated on one mainframe, which IBM has touted in television advertisements that began this month. In one, dubbed ``The Heist,'' a frantic executive calls the police to report the theft of a vast roomful of servers, only to have a carefree underling remind him that all of the data was moved to a single mainframe standing in a corner.

More than 100 zSeries customers bought the mainframe with Linux, and others may have incorporated the software on their own, IBM said.

``It has been a very material factor in the resurgence of the mainframe,'' John Morris, IBM's vice president for zSeries sales, said in an interview. He declined to estimate sales growth for the current or future quarters.

It's very funny.

Sure, it's theoretically possible, but who the hell would actually do such a thing?
