Support for Virtualising Exchange Server 2010 SP1 has changed..?

The support stance for virtualising Exchange Server 2010 SP1 has changed significantly over the last few days and seems pretty unambiguous. However you need to be a bit careful about what actually is and isn’t supported. The statement from Kevin Allinson on the Exchange Team blog yesterday reads: “Combining Exchange 2010 high availability solutions (database…

1 AD Site, 1 DAG = no DAC

So as the TechNet article (Understanding Datacenter Activation Coordination Mode) explains you can’t enable DAC mode in Exchange Server 2010 for a DAG where all members are in the same AD site…  So what happens if you lose your primary data centre where your Witness Server is located and you do have a single DAG…

CCR or SCC?

Have had this discussion on many occasions and this 3Sharp whitepaper by Missy Koslosky would have proved very useful as an external reference point… High Availability Choices for Exchange Server 2007: Continuous Cluster Replication or Single Copy Clustering In conclusion…  (this isn’t the only bit I read) “Exchange Server 2007 is a mission critical application….

3 Data Centres and a File Share Witness

What’s the guidance if you’ve got 3 data centres, you’re stretching Exchange 2007 mailbox CCR nodes between two of them and the link speed and latencies are similar between all 3.  Should you put the File Share Witness (FSW) in the 3rd data centre? In my opinion yes I would recommend putting the FSW in…

Crossover cables and CCR…

So can you just use a crossover cable for private cluster communications between CCR (& SCC) nodes.  Well the answer, not very surprisingly, is yes; but there are a couple of caveats… Be careful and test the cable, especially if it’s a DIY job; And make sure you get speed and duplex settings right: “If…

Backup your DPM data into the cloud…?

This is a smart idea…  The DPM UI can be used in conjunction with Iron Mountain CloudRecovery to backup your data into the cloud.  For protecting Exchange Server this means that you could use short term protection of your databases to disk via DPM as you might normally do, but instead of longer term protection…

Stress testing Exchange in a virtual environment..

I’ve been asked a couple of times about stress testing an Exchange server sitting on a hardware virtualisation platform. What would you have to do differently? Well to be honest I haven’t ever done it and a quick trawl of the Internet and internal Microsoft alias’ shows that there still isn’t much experience out there…
