Sounds like the database being large is a red herring. Exchange 2010 supports up to 64TB databases and the max recommended is 2TB. I've seen a lot of really large databases that haven't had stability problems. So your issues may be related to something other than large database size.

You can use the default or a named instance. In the Topology Builder when defining SQL Backend, it'l have a radio button to use the default instance and another radio button to enter the name of the instance.

If you perform step 5 and DAC is enabled on the DAG before you simulate the failure, when the Primary Site comes back up, those servers will not mount databases since DAC is enabled and cannot contact the rest of the DAG Servers.

Because that's the wrong -Identity. Look at my original post and you'll see the format.

Sounds like firewall rules to the VPN segment are blocked. Peer to Peer audio calls will use ports 1024-65535 TCP/UDP. VPN segments to FE for Conferencing should have 49152-57500 open for MCU Audio/Video/Conferencing.

Tue, 31 Jan 2012 15:05:44 +0000

You won't be using the FSW since you'll have an odd number of nodes. You can see in the Visios (and I do mention it in the text) that there is no FSW due to there being an odd number of nodes. You would still specify a FSW though as you only temporarily use the FSW as you build the DAG when having the even number of nodes or during failback as you add the primary site's DAG members back into the DAG when restoring service to the Primary datacenter. Once you add that third node back, the cluster automatically switches to Node Majority instead of Node Majority with Witness when you only had 2 nodes.

No, don't use a hidden share. I've had another person try this and I had to fix it as there were a ton of issues with it.

That's after you have Lync deployed. You merge topology and then import configuration.

Did you do the following? 1. Install Topology Builder Tools 2. Definite Enterprise Edition Front End Topology including the File Share and SQL Server it talks to 3. Publish Topology which creates the Central Management Server Databases and Front End Databases on your SQL Server? The above must be done in an Enterprise Deployment to allow you to run Install Location Configuration Store on a Front End Server which installs SQL 2008 Express on the local Front End Server and creates a copy of the CMS (xds database) on the local server's SQL Express install.

Lync Standard Pool or Lync Enterprise Pool?

Elan Shudnow's Blog : Exchange 2007 UM to Exchange 2010 UM Partial Upgrades and Redirects

Wed, 25 Jan 2012 22:10:54 +0000

OCS 2007 R1 you must create a new UM Dial Plan and re-integrate a new OCS Dial Plan with a new UM Dial Plan. So OCS 2007 R1 Location PRofile integrated with old UM Dial Plan with 2007 UM Servers. And a new OCS Dial Plan with a new UM Dial Plan with 2010 users. Then as users are migrated to 2010, you move them into the new OCS and UM Dial Plans. If using OCS R2 with CU5 + and Exchange 2010 SP1, OCS 2007 R2 CU5+ Lync can do Mailbox Version Lookups and route to the proper UM Servers whether it's 2007 or 2010 in the same Dial Plan. In this case, it's as easy as just adding 2010 SP1 UM Servers in the same Dial Plan that has 2007 UM Servers and OCS 2007 R2 CU5+ and/or Lync will route to the correct UM Version.

You said you don't see anything with get-clientaccessarray. Yet you say you checked and the CAS Array with the FQDN does exist for the AD Site. What you're not telling me is how you saw that so not sure how I can help you since you just said that you cannot see it and then said you can see it. I need more information before I can help.

The official documentation is here: http://technet.microsoft.com/en-us/library/dd3510... There is a section entitled, "Restoring Service to the Primary Datacenter" It discusses on how to go back to your original FSW.

There can only be one CMS Master "Pool" in the environment. So if your Front End Pool is highly available, so is your CMS. If you first deployed a Standard Pool and then a HA Pool, you would want to move CMS to the Enterprise Pool so CMS becomes Highly Available.

Well part of the failover process is to remove the primary site from the cluster so that you maintain quorum with just your failover DAG members. So to the DAG members in the failover site, they are the only servers in the DAG now and that's why you can maintain quorum. The only potential problem is these DR servers still think there is a copy maintained in the primary site. Because of this, if you have backups occuring in the DR site, logs will not be truncated since there is a copy maintained in the primary site. You could, however, break the copy to the servers that were in the primary sites and now log truncation will occur. When the primary site comes back up, you will need to reseed the databases back to the primary servers.

Without knowing much about your business requirements and what the conceptual design is, it's hard to be definitive. But typically, if you have a Primary Site and a Failover Site you would use the same DAG for both locations so you can replicate databases from Server in Primary Site to Server in Failover Site.

I haven't seen anything saying that it is unsupported. I would probably advise against it. Keep in mind that the usage from a drive space will be very minimal. In OCS 2007 R2, a 100,000 user pool would use approximately 10GB of space. I have not seen any metrics in Lync but it would be about the same and the usage was so minimal the above statement wasn't carried over to Lync. So personally, I would just make sure you have a few GB free for the Standard Edition databases on C:\\ and you'll be covered.

There's no real guidance. An SBS handles up to 5,000 users in a branch and I would say that the guidance has you deploying the same hardware that you would for a typical Front End. Since you're only using 30 users, I would say a couple cores and 4-8GB of memory would suffice.
