[ILUG] test plan omega - linux on the s/390

[kevin lyda]

ok, anyone here with a fairly large server room filled with linux boxes
(or even solaris/freebsd/etc) will find this of interest.  i don't think
the magic numbers in this quote are 5 digits long, i think they're both
two digits long: 10x10.

    What is Test Plan:Omega and how is it different from Test Plan:
    Charlie?

	We found that we could get 41,400 servers in a partition in a G5
	[machine]. The idea of Omega is to see what we can do with an
	entire machine, and preferably the biggest machine we could
	get our hands on. At the time we ran the test, the biggest
	machine around was a ZZ7, which has 12 CPUs at around 160 MIPS
	per CPU. It's a pretty good sized box. It used to be the top
	of the line -- it's a lot of iron. We were able to get some
	standalone time from one of the outsourcing vendors. They were
	willing to give us two hours on the box just for the coolness
	value of finding out how far we could push this thing. It had
	16 gig of RAM.

	The design point for VM is 99,999 simultaneous logged-on
	users. Our test was to take Test Point: Charlie and just go
	nuts. We've got a huge amount of RAM, all the I/O horsepower we
	could ever want. We got 97,943 images.

	There are recently introduced z900s that are four times that
	size. The largest web facility I know of is around 14,000
	servers. We're talking about several times the size of the
	largest Internet facility in a single box. That box is ten by
	ten square feet.

i hear ibm is doing linux ads.  i think they should do one with
808state's 10x10 and watching a server room with 5000 boxes morph into
a 10x10 foot box.  they could even split the cost with adidas or nike
- you'd need to do something with the space that's left over!  "note:
basketball nets sold separately."
