Exchange 2007 SCC - Combining Quorum Disk with Log Disk?

Hi all,

I'm after some advice here really, we presented some new Log drives on some of our Exchange 2007 SCC servers to replace the old ones (faster disks, better IOPS).

One thing we forgot about is that the old Log drive is actually a Raid Group on the SAN, which is split into two LUNs. One for the Log Drive and a small carving for the Quorum disk.

We have in fact already moved the Logs from the old Log LUN to the new one, the only thing that is left to move is the Quorum drive. The New Log LUN is also presented with Maximum space assigned, and is assigned with the maximum partition size in Windows.

I've done some testing in the Lab here, and it seems that the new Log Drive can be the Witness drive, as well as the Log Drive without problem, no adverse effects were encountered during testing.

Can anyone suggest to me any further downsides of sharing the Quorum and the Log LUN together?

The only one I can think of is that the Quorum Disk can't be moved independently of the SCC Exchange Cluster anymore with the Cluster Group "Available Storage" /Move:<NodeName> command.

I can look at getting another LUN assigned if it's considered better practice, or otherwise seeing if the existing one can be shrunk a little to make room for another Disk.

Thanks for reading!

It is always best practise to seperate everything as much as possible. Therefore if you can get another LUN I would do that, as it will make things a lot neater.

In the end we were able to present some small LUNs for the Quorum disl. Problem solved!
