Awaiting Windows 2012 Server R2

Its just amazing that Microsoft has significantly improved on the updates and release frequency. We got Windows 2012 Server in Mid of 2012. Its almost an year and Microsoft has announced the Release 2 for Windows Server 2012.

I am also keen to know how well Windows Server 2012 R2 improves specific to HyperV. As per the information posted on Microsoft blog, few of the new features with Windows Server 2012 R2 are

Live migration compression: Compresses virtual machine during live migration to improve migration speed. Yet to get clarity on this. But my assumption is that this will compress the Live Migration traffic so that the data transfer will happen quickly and the overall live migration time will be improved.

Hyper-v Replica:  Hyper-V Replica provides a cost-effective way for SMBs to implement disaster recovery/business continuity scenarios. Extended replication, now add a second replica to add extra protection for your VM at offsite location or hoster. Finer grained control of replication, now choose 30 sec interval or 5 minutes (default) For other scenarios choose 15 minutes.  Windows Azure will support orchestration of recovery using Hyper-V DR replica’s and system center VMM on premise.

Dynamic memory for Linux guests: Automatically reallocates memory between virtual machines that are running Linux as a guest OS on a Hyper-V host. This is one of the feature I wished to have. I am sure that with this feature, the Physical to Virtual ration will improve drastically in an environment where we have Linux VMs.

Online VHDX resize: Online VHDX resize allows a virtual SCSI disk to either grow or shrink the VHDX file whilst attached to a running virtual machine. Simply Great !

More to come soon !

Cheers
