Exchange 2010

Microsoft Windows server 2008 standard
December 5, 2009 at 20:38:32
Specs: Windows 64
Im buying two Dell computers with 4 320 gig hd's in each. One is a quad and the other is a dual. I was planning on having my dual in the DMZ zone with client access/hub and then inside the network the quad. I wanted to set up the proper raid for exchange. On my quad I was going to have 2-3 virtual machines all on server 2008r2. What is the best way to set up raid and what is the process with dell poweredge's. I have done raid before through the bios with a raid hardware card with 2 sata drives. On my quad should I set up the raid on the host then dont worry about anything on the guest's the virtual machines one having the mailbox role for exchange? Is that the proper way to setup exchange?

I'm not sure I understand your question about the RAID. Since RAID is primarily used to protect against hardware failure or to increase throughput/capacity limited by the hardware, you would just set it up as you have before. It doesn't matter what you are running on the computer.

As to the DMZ idea, I don't quite get why you provided this information. I assume you are using DMZ to mean a completely un-firewalled/un-NATed computer. If that is the case, I would suggest you instead just forward the appropriate ports to the appropriate interfaces. There is no need to have Exchange server or anything else completely open, when the Exchange services you need access to only use a few specific ports.

As to where to install Exchange, that is pretty much up to you. Exchange doesn't really care if it is on a virtual computer or a real computer, provided it has the resources necessary for it's particular application.

PS: Nice website, but be sure to spell/grammar check your writing.

I was curious on how to properly set up raid using dell powerege's with 4 hd bays with 4 320 gig hd's in each. If its something I do in server 2008 disk management or in the bios. I heard you want raid 1+0 and 5 for exchange.


Re: The site which one?

You should definitely set it up as a hardware raid. How you set it up all depends on what you want. There are lots of different ways you could do this. I would imagine you want redundancy (to protect from data loss). So you could, as example, make all 4 drives redundant and therefore be protected from up to 3 simultaneous drive failures. Or you could combine the drives into pairs, and then make each pair redundant. Then you would have double the space, and protection from a drive failure. Or you could use one drive with no RAID and mirror the other three. My point is, there are quite a few ways to do it, and which you choose depends on the level of protection you need from drive failure, the amount of storage space you need, and the performance needed.

I was talking about your busienss site, 562 networks.

Oh Ok. Ive been doing alot of research on 2008R2 and there was some talk of new ways for raid and since nothing is really out on 2010 exchange I was thinking there is more options there also.

I usally do Hardware raid cards with 4 sata drives.

RAID can be setup in hardware of software. If you have the option of doing it in hardware, I can't think of any reason to do it software. If it is done in hardware, the software has no effect. It doesn't matter if the drives have Server 2003, 2008, Windows 95, Google Chrome, or just a bunch of pictures.

Exchange 2010 is robust enough to not care about RAID because of the introduction of DAG storage groups. If you do want to set up a RAID array (which is the best practice for peformance and redundancy) then set up the OS on a RAID1 (mirror) and the data LUNS can be on a RAID5. Essentially you want a seperate LUN (partition) for transaction logs, databases, and the operating system. Note logs are write intensive and databases are read intensive hence why they should reside on seperate LUNS for optimal peformance.

Additionally DO NOT set up the RAID using the built in Windows utilitys. You will want the server hardware to provide the RAID functionality so the processor cycles can be used optimally for system processess.

Note Exchange should NOT be installed in a DMZ. The only component that should be in the perimeter is the Edge transport role that resides in a windows workgroup, or any "smarthost" that relays mail for Exchange upstream. All other roles should be within the secure network.

I would encourage you to do some reading up on Exchange 2010 as unless your familiar with previous versions of Exchange a best practice installation may be outside of the scope of your abilities.
