I recently installed the new System Center Virtual Machine Manager 2012 RC, part of the private cloud products released by Microsoft.
For this installtion, I used a server on which I installed Active Directory first to make it a domain controller, followed by the installtion of SQL Server 2008 R2 Enterprise edition on the same server for use by SCVMM 2012.
Here are the screenshots for the SCVMM 2012 RC installtion that followed SQL Server installtion:
The Pre-requisites check failed here showing a missing Windows Automated Installtion Kit (WAIK) that it requires to proceed with the installtion. I then downloaded and installed WAIK for Windows 7 as follows before proceeding with the SCVMM 2012 installtion:
ReFS stands for Resilient File System. Although it is designed to be better in many dimensions, resiliency stands out as one of its most prominent features.
Maximum size of a single file
Maximum size of a single volume
Format supports 2^78 bytes with 16KB cluster size (2^64 * 16 * 2^10). Windows stack addressing allows 2^64 bytes
Maximum number of files in a directory
Maximum number of directories in a volume
Maximum file name length
32K unicode characters
Maximum path length
Maximum size of any storage pool
Maximum number of storage pools in a system
Maximum number of spaces in a storage pool
In Windows 8 there is no way to convert data in place. Data can be copied.
ReFS cannot be used on removable media or drives. This is not implemented or supported.
• Named streams
• Object IDs
• Short names
• File level encryption (EFS)
• User data transactions
• Extended attributes
ReFS is supported on the fault resiliency options provided by Storage Spaces. In Windows Server 8, automatic data correction is implemented for mirrored spaces only.
Support for Clustering
Failover clustering is supported, whereby individual volumes can failover across machines. In addition, shared storage pools in a cluster are supported.
Capabilities of striping, mirroring, or other forms of RAID
ReFS leverages the data redundancy capabilities of Storage Spaces, which include striped mirrors and parity. The read performance of ReFS is expected to be similar to that of NTFS, with which it shares a lot of the relevant code. It will be great at streaming data.
ReFS does not itself offer deduplication. One side effect of its familiar, pluggable, file system architecture is that other deduplication products will be able to plug into ReFS the same way they do with NTFS.
Second Level Caching between DRAM and Storage
ReFS does not explicitly implement a second-level cache, but customers can use third-party solutions for this.
ReFS and VSS work together to provide snapshots in a manner consistent with NTFS in Windows environments. For now, they don’t support writable snapshots or snapshots larger than 64TB.
Hyper-V has been an built-in role on Windows Server 2008 and later versions of Windows Server platforms. This capability has always been missed on a client platform like Windows 7. However, Microsoft attempts to fulfill this gap by introducing Hyper-V now as a built-in Windows feature on the new Windows 8 client operating system, to be released.
In order to use Hyper-V to host virtual machines on your Windows 8 PC, this feature first needs to be enabled from the Control Panel.

More Insight into New Windows 8 features….coming soon….
So I installed the new Windows 8 Developer Preview on a seperate volume on an existing computer that already had Windows Server 2008 R2 installed on the C:\ volume.
The first step as usual was to insert the Windows 8 DP DVD and start the installtion from the Windows Server 2008 R2 system in which I was already looged on as an admin.
Here is the series of screens that you get as you proceed with the installation:
Since I already had an NTFS formatted volume with enough disk space, I chose to install Windows on that volume. However, if you need to delete, recreate or format new volumes, you must start the installation by booting from a bootable Windows 8 Dev Preview installtion media.
More to come on New Windows 8 features for the IT Pros…
