VMWare vFabric SQLFire vs memcached vs AppFabric vs ???

VMware vFabric SQLFire is an in-memory distributed SQL-based cache which can work with a traditional database to persist data to disk. Distributed, in-memory shared-nothing fault-tolerant SQL data management system. It offers a JDBC or ADO.NET interface for querying the datastore in a pure SQL manner, but the keys and indexes are stored in memory to provide high scalability, availability and better performance. Leverages the "time-tested", production GemFire technology but adds a SQL interface. SQLFire is being offered as part of vFabric Advanced for $1,800 per VM, but it will also be offered as a standalone product

How to install VMWare Player after Hyper-V role is enabled in Windows Server 2008

Once you enabled Hyper-V role on Windows Server 2008, you will not be able to install VMWare Player or  Server. First will complain that it cannot be installed on Windows 95, 98 or 2000 - fair enough, but totally misleading - latter will give error message noting that you have to disable Hyper-V.

It appears that you cannot run both hypervisors at the same time, but there is a light of hope.
thanks to this posting: http://blog.baeke.info/blog/_archives/2007/12/18/3416738.html

1) run the following "as administrator" in console - it will give you some GUID
bcdedit /copy {default} /d "No Hypervisor"

2) now copy\paste this GUID into the following:
bcdedit /set {GUID} hypervisorlaunchtype off

3) reboot - now you have a "No Hypervisor" boot option

P.S.: I also disabled all "Hyper-V ... " windows services, probably it was an overkill...
