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…

3 into 4 can go…

Once you’ve determined the number of Exchange Server 2010 mailbox database copies you’re going to use it makes sense to deploy a complimentary number of mailbox servers in the DAG.  If you decide to go with an odd number of database copies go with an odd number of nodes; if you use an even number…

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…

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…

Archive v Big Mailboxes

Ok so this may not be a straight choice for most and an archive solution can complement Exchange for many environments, but there are some who have not yet deployed an archive solution and who can look at it as a straight choice – small mailboxes and an archive solution or big mailboxes and no…

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…
