Update to improve cloud service provider resiliency in Windows Server 2012

Microsoft released an update to improve the cloud service provider in Windows 2012

Note : The KB2870270 roll-up hotfix replaces KB2848344.  This hotfix contains the fix for Trim as well as ODX.  It is no longer necessary to disable Trim or ODX with this fix applied

The following issues are also resolved with this update:

- An Windows 2012 Hyper-V Cluster that uses CSV is moved or is toggled between directed access and redirected access when the performance monitor is running. In this situation, the performance counters no longer function.

- An Windows 2012 Hyper-V Cluster and the Virtual Machines VHD files are stored on a scale-out file share and the server is under a heavy load. In this scenario, the server may crash, and you may receive a Stop error message that resembles: STOP: 0x000000C2 (parameter1, parameter2, parameter3, parameter4) – Notes: The parameters in the Stop error message vary, depending on the configuration of the computer and not all “Stop 0x000000C2″ errors are caused by this issue.

- When you use the Windows thin provisioning feature on a Windows Server 2012-based computer, you experience the same I/O delays or I/O stalls that occur during the volume-unmounting process in NTF volumes.

Plus the issues that are described in the following Microsoft Knowledge Base (KB) articles are resolved:
