MacDailyNews - Where Mac news comes first

This is a big deal. A number of articles in the computer trade press over the years have given one reason why enterprise customers are not interested in OS X Server as the lack of virtualization.

Of course, Apple doesn't have a heavy duty sever to go with change. Virtualization usually takes place on 16, 32 and bigger chip systems.

But, maybe this also presages a change there as well. With 4 core chips, just maybe Apple will finally come out with a 2U server with 16 cores. That could use this new license.

2U 16 core servers are cheaper to buy, and run, than two 1U 8 core servers. But, they can't always be utilized fully. That's where virtualization comes in.

Hopefully, Apple will come out with those larger models soon.

I'm all excited now...

er.. why on earth do people want to do this?

Ahhh so the use for this, is for hardware that Apple doesn't even make yet? Is that what you're saying Mel?

Is this something people who use *current* (as of October 31 2007) Apple server hardware would care about?

I know my comment was just posted before yours, so you couldn't have read it, but did you read the actual article rather than MDN's summery?

You should.

"Is this something people who use *current* (as of October 31 2007) Apple server hardware would care about?"

While current machines could use it, it wouldn't make that much of a difference, as current machines, used for the tasks they are normally bought for, are heavily utilized already.

I can't help but think this will lead to the much requested 2U model.

If I paint an Apple label on my Shitbox (Dell), am I allowed to run Mac OS X on it?

This is an incredible turn of events!

Although this is a really limited window of opportunity for virtualization, I think this is Apple's "measured and controlled" way of experimenting with virtualization. Getting more experience and knowledge on virtualization may allow Apple in the future to license VM versions of Leopard server or future server OS X versions to non-Mac servers.

If Apple eventually allows virtualization on non-Macs, Leopard will instantly be "played" with in server rooms around the world, giving sys. admins a taste of what it's like. I believe this could easily be the corporate world equivalent to what the Intel transition and bootcamp have been for consumers.

Is this a sign that Apple is really planning an all out assault on the server market?

Very cool indeed!

'but did you read the actual article rather than MDN's summery?'

You might also read the summary.

Virtualization is a fab, There is no performance improvements with virtualization, in fact just the opposite is true. With VMware you buy a $22,000 VX Server and the VM Server software is installed you can run at most 3 Windows 2003 Server virtualized at once before the system is noticeable slow. Which makes the cost per server about $7,333.00 plus the cost of Windows 2003 server licenses. Foe that much money I can buy a lot of Cheap Windows PC's and get better performance out of them. But, If your company as more money then brains I guess virtualization is the right choice.

You're missing the point. With large, many core servers, all of the cores are often not being utilized. Going virtual, they will be. It's all about load balancing.

Servers that are fully utilized won't be virtualized, that's not it's purpose.

Demon -- I was following your argument until the juvenile "more money than brains" remark."

Good point, will the power of XServers step up to this? I don't think Apple will cave any time soon in letting it be virtualized on non-Apple branded hardware, though I don't think that would necessarily be a bad move for Apple...

Maybe this is prequel to new hardware, 8 core 2U E server
I can smell new supercomputer at VTech.

to XServer, and Mac Pro desktops.

i didn't tell u

This is a prequel to running OS X on a Wintel machine via VMWare...
