Clustering, Hyper-V, SQL Server, Storage, VMware

When building virtual clusters under any HyperVisor you need to make sure that all the nodes of the cluster are being hosted on different LUNs on the hosts. If you build the VMs on the same LUN and that LUN fails for some reason then both of the nodes of the cluster will be down, and the whole...

I've submitted a lot of sessions to a lot of conferences over the years.  And while the feedback from some of the conferences is a little cryptic thanks to the review team only having access to canned responses, it'll do.  Now personally I'd love to get specific feedback saying exactly why my...

As hopefully everyone that is using VMware's vSphere in either data center knows VMware's vCenter runs off of a Microsoft SQL Server database (by default).  Now as good as they guys at VMware are at building a virtualization platform there database leave a little to be desired.  I've identified a...

Backup & recovery, SQL Server, vCenter, VMware

VMware's vCenter system uses SQL Server as it's default database platform.  One thing that needs to be looked into for a lot of VMware installations is the backup setup for the vCenter databases.  Often I find the vCenter databases configured in SIMPLE recovery.  Now this doesn't mean that the...
