Pooled Resource Clustering

Dear All,

Just downloaded a not too great white-paper (sponsored by HP) called SQL Server Infrastucture Optimaztion and it had a brief but eye catching section on something called 'Pooled Resource Clustering'. See below

Pooled-Resource Clustering
Pooled-resource clustering is a combination, of sorts, of Windows clustering and virtualization.
Essentially, it€™s a means of allowing SQL Server instances to become €œvirtual SQL Servers€? in
the sense of true VMs. They€™re encapsulated and can be easily and quickly moved between
physical computers. It borrows concepts from Windows clustering but does so with a crucial
difference that eliminates the resource management overhead that comes along with Windows
clustering. Another term for this technique is shared storage clustering.
Technology Overview
With pooled-resource clustering, a cluster of servers€”which can all have different hardware
specifications€”are connected to a single, shared storage system (typically a SAN). By
leveraging a Windows-based cluster file system, each of the nodes in the cluster can €œsee€? the

same storage area. That is, they all have (for example) an S drive,


I googled this and can't find any more about it. So my question is simple can anyone provide more info about this method. I tried tried the authors web site burt its all sales info address(

On the surface this seems a bit of a hack to me?

Thanks
