Evaluation of the Polyserve 3.6.1 is underway.

Recently completed the upgrade of our Development cluster.  All went smooth. 

This is another one of those difficult upgrades that requires multiple outages (though small).  First you have to un-install the software and then install the new software.  So this causes an outage.  The File systems also have to be upgraded, so you have to stop using each file system to upgrade it, this causes another outage. 

So far things have been quick and no issues.

Definetly had we not completed the 3.4 to 3.6 upgrade, this would have been very difficult, as the 3.4 to 3.6 upgrade was more complex.

No word yet on Polyserve support for sql server 2008.  Though based on the sparse and ADS (Alternative Data Streams) file system options in 3.6.1 they are very close, and I'd bet you will have to be on 3.6.1 as both the sparse and ADS seem to be necessary for sql server 2008.
