With something like Hotmail I would assume you need some kind of thin provisioning mechanism for disks. I'm not sure if DAS can do that and for something like Hotmail / Gmail you would pretty much have to thin provision your storage design.

IF you were to plan DAS replicas as backups and no long term storage how would your design change?

I am just saying that currently working for an Exchange 2007 migration project for 180K users, I dont see the scalability to 300M users in the near future... especially when you are promising up to 5gb of storage per account with no current sunset of data storage (all message stored for X months, etc) On Wed, Sep 24, 2008 at 12:19 PM, James Kerr <[EMAIL PROTECTED]> wrote: Thanks for the info Kat ----- Original Message ----- From: Kat Collins <mailto:[EMAIL PROTECTED]> To: MS-Exchange Admin Issues <mailto:exchangelist@lyris.sunbelt-software.com> Sent: Wednesday, September 24, 2008 1:24 PM Subject: Re: Hotmail HAHAHAHAHAHA!!!!!! Holy [EMAIL PROTECTED] that is hilarious! I lurve me some Exchange, but there is no way in Hades that Exchange as it stands now or in what I understand for the next 3 generations, could handle the volume, load and uptime requirements of Hotmail. Knowing the backend infrastructure required to support the number of users in Hotmail, I just can't see it. Sorry... :-) On Wed, Sep 24, 2008 at 8:45 AM, KevinM <[EMAIL PROTECTED]> wrote: Kat would know, she might have Ran hotmail for a while or something like that..... The plan going forward with the wave 14 Exchange push is to migrate hotmail to Exchange. This message is coming to you live from a Microsoft hosted E14 server. Not that I can tell you anything more than that, but you can guess that this means that they have the beginning of that move in place. If it will happen or not is in the air still, but I can comment I do know that it was a goal. -----Original Message----- From: James Kerr [mailto:[EMAIL PROTECTED] Sent: Wednesday, September 24, 2008 8:23 AM To: MS-Exchange Admin Issues Subject: Re: Hotmail I did a little research and it seems they maybe still using BSD for DNS purposes.
