Hello Exchange Experts,

Planning to Upgrade Exchange 2007 SP1 to Exchange 2010.

------------------------
Our Current Setup in ONE location ( Data Center1 )

Windows 2003 Domain & Windows 2008 R2 AD DSs added into Windows 2003 R2 Domain

Exchange 2007 SP1 on Windows 2003 Ent R2 SP2

Two Mailbaxes ( SCC Node1 & Node2 )

Hub&Client Access (One Box) "OWA page is customized with company profile logo "

Edge Transport ( One Box in DMZ )

No Unified Messaging in Current setup & Upgrade Plan as well

------------------------
------------------------
Upgrade plan ..

2 Datacenters ( DataCenter 1 & Data Center 2 ) One Domain , One Default Site , Only Physical locations are different

every exchange server will be redundant , Mailbox will be Cluster.

One server each Exchange role , One SAN , One Tape Library will be in Data center 1 & One Server each Exchange role , One SAN , One Tape Library will be in Data center 2

Purchased , 2 Quatity of Servers for each Role , 2 Quantity of Tape Libraries , 2 Quatity of SAN Storage

All this upgrade plan made before launched Exchange 2010 as we had decided to use Exchange 2007 CCR setup

But CCR\SCR is no more in Exchange 2010

Which RAID level is Best Practice for SAN Storages to Exchange 2010

-------------------------
Please advise , How to Upgrade from Exchange 2007 to Exchange 2010 and How to use these Hardware Resources in Two Data Centers.

Thanks In Advanced

Regards, Amjuu ..

I will write notes since such project has a lot of To DOs however here are my thoughts:

- Upgrade Exchange 2007 to SP2.

- Configure the 2 locations as 2 AD sites.

- you will need extra servers since you said 2 servers for each server role, since you have 2 sites then you need 4 (or HA in DR site is not manadatory).

- for Exchange 2010 RAID 5 is good but have some write penalties, RAID 10 is optimum but expensive, but keep in mind that youd don't need RAID configuration if you deploy 3+ copies.

- you don't need SAN you can use local harddisks.

- you will need some HW for the DR site.

- use the DR site in passive mode, don't provide email services or active DBs from the DR site.

I agree to what busbar wrote!

And an addition is, DAS storage isn't so expensive either..

here is a nice video:

and a link:

for the storage i have published an article called the consultants' Corner http://eseblog.enowconsulting.com/ you can find it in the first edition, you will find a question about storage similar to yours, basiclly when it comes to storage I always size the exchange deployment and provide the IOPs to the storage vendor, I tell them that those "EXCHANGE COMMITTED IOPS" meaning that those IOPs will be committed at the storage controller, they might be (magnified) due to the storage technology or RAID architecture.

don't worry about what is the best practice the storage guys will provide it to you, as long that they give you the required IOPs with the level of availability and within the budget then you are fine and this is the exchange best practice. at least this is my opinion.
