two exchange 2010 servers, one in office, one in datacenter?

Greetings,

I have two licenses for Exchange 2010. I am building one right now at the data center.

Is there anyway to install one at the datacenter and one at the office and have them communicate with each other? What I would like to do is have the one in the datacenter be the "primary" and simply sync with the one in the office. Users in the office could then retrieve email from the office server and if we ever went down, they could still get email from the datacenter server.

thanks

In this case you need site resiliency. I guess Datacenter will be a DR site only. If you have users in datacenter site also, then design would be different. In that case, you need to look for High Availability for non mailbox roles too. Like CAS/HUB.

Thanks for the quick replies.

The datacenter has no users but would actually be primary production, not DR, since we trust it more regarding uptime.

I'll check out the links. I've yet to find a step-by-step for setting this up. I'm new to 2010 so need good directions.

You better hire a consultant or you can check with MS too. They can help you to put a right design.

I would recommend reading some exchange 2010 book "like exchange 2010 inside out" before installing it on production. msexchange.org is also good place to start with.

Sounds to me like you want to have the e-mail continuity setup with the office being the fail over site.  This can be a very complicated undertaking - you are essentially deploying a database availability group (DAG) and creating mailbox database copies, which replicate across your WAN.  Are you migrating from an existing exchange environment?  If you are just interested in email continuity I would look into something like geminare http://www.geminare.com/Products/cloud_recovery_auto-failover

that would / would've been an additional benefit. I plan to replicate to another SAN / host at the datacenter. what I was really trying to do was alleviate some of the traffic across my wan when users access the exchange server at the datacenter. I have a 50 Mb e-line from TW but that is also used for replication. here they use outlook / exchange as a file server / FTP, constantly attempting to send attachments that exceed the 50 Mb limit.

Yeah the email as a file server is a constant worry.  If traffic across the WAN is your main concern, having the mail store and hub connector in the office will help some, but only for in house email circulation.  Sending large attachment to outside users will still put pressure on the WAN.  I guess you would have to look at where are the biggest offenders and build around that.  The technet video series is a pretty good resource for seeing different configurations in action.  I would watch a few on the DAG operation  http://technet.microsoft.com/en-us/exchange/ff963526

thanks. I'll check out the videos. I need to at least get the 2010 server into production before the end of the month, so this may be a secondary project now. Just wasn't sure if I needed to do anything special in the initial install to later implement DAGs or set up the second server in the office.

thanks again everyone

I know this question is a few days old, but if you are deploying Exchange 2010 then don't make the common errors that will make the DAG hard to implement:

- Create an RPC CAS array.
- Install Exchange 2010 on to either Windows 2008 R2 Enterprise edition of WIndows 2012. You cannot change the Windows version later and the DAG requires either of the above.

Remember that the DAG only provides database high availability, not client.
I would also question having the "primary" in the data centre. Lose your internet connection and you have no email. Keep it local. By all means use the data centre as the primary delivery point for email, so if your main office is down email comes in to the server correctly.

thanks for the tips Simon. I just found out that some of the partners are going to Bermuda so I don't want anything to interfere with them getting emails. You stated in another of my Exchange 2010 install questions, regarding SSL certs, that there should be no downtime if completed within a 24-hour window. I am skeptical since I am new to 2010, and with a few of them being out of the country, so I may wait until next weekend to finish it to avoid any potential issues with them losing email.

I was also concerned about losing the internet connection in the office, which has happened before. The data center has never lost TW internet service. However, that isn't to say they won't or that my equipment won't fail. I just think it is more likely we would lose the office connection before the data center, at which time email would still flow and be received to mobile devices over 3G / 4G and to outlook via the terminal server at the data center. Additionally, we have two internet circuits in the office. One is a TW 50 Mb e-line and the other a cable business class DSL at 15 Mb. Users go out over the DSL but access email over the e-line. I am about to configure a VPN between the data center and office over the cable line so if the e-line goes down, users could still access the email server over the cable VPN. I am working with SonicWall and a local firewall guy on this set up. Hopefully it'll work. Anyway...

I am a little confused where you question the "primary" in the data center, but then state "By all means use the data centre as the primary delivery point for email, so if your main office is down email comes in to the server correctly". Would you explain that, if you have time? Seems that if the office is down, DNS will still point to the office so mail would not reach the server. Now, we use Spam Soap and they allow editing the IP address which points to our server and our mail.domain.com DNS entry. So it may be as easy as changing that IP to point to the data center server and then waiting for it all to update so email flows again. This is on my list of questions.

thanks again

If you use a DAG to have copies of the email in two locations, then only one of those can be live at at time. If you lose the internet connection then one of those servers will be down.

Therefore you will have two options.

1. The FSW (Which manages which server is live) is in the data centre, the data centre server stays up, the local server fails.
2. The FSW is local, the local server stays up, but only users in the local site have access to email.

Now, if you have multiple internet connections then you could run with the server local for maximum performance. In the event of a failure of the connection have a method to use the second connection. Exchange doesn't care how the link is made, as long as it is there. I have had clients run a DAG over a 3g connection during an outage.

Furthermore, what you could do is have all email delivered to the server in the data centre, and even if you have an outage, you just need to get a link between the two to keep email flowing. This is exactly what I do with a client right now - we have a cheap DSL line for backup, in the event of a failure of the primary I will run everything over that second connection.

Simon.

thanks for the info, as usual, Simon. I will look this over and share it with the people I am working with on the networking side of this.

It has been requested (read ordered) that the primary / live email server be in the datacenter. I am going to investigate setting up a DAG in the office, while taking into consideration the bandwidth and networking requirements involved, as well as the steps needed to have email delivered to the office (where DAGs would be) if the datacenter email server is inaccessible for any reason.

thanks all for the info.
