Windows 2012 R2 CTP and SQL Server 2014 CTP1 bits is now available for MSDN subscribers

Several developers reported availability of the new Windows 2012 R2 Datacenter preview , SQL 2014 CTP1 bits and System Center 2012 R2 last night. More news will be available during this weeks Tech Ed conference in Madrid.

Microsoft is said to focus on storage and networking in the new Windows 2012 R2 version and one of the news is automatic storage tiering, which allows the system to automatically decide which files are most accesses and place them on the fastest avaliable storage (SSD) within a Storage Space. Less frequently access files will be keept on normal hardrives.

Deduplication is also new in windows 2012 R2 and could potentially save lots of space, in particular when it comes to virtual hard disk in virtul environments. It might even increase performance for virtual hard drives when streamed servers are used.

On the networking side migration of virtual machines between hosts have been improved by compressing the virtual hard drive before copying. There is also a update to RDMA (remote direct memory access) which allows a server to be copied directly between each hosts memory without touching the CPU in either server, cutting transmission time in half, according to Microsoft.

There are also some updates to the Azure integration, one being the Hyper-V Recovery Service, which operates from Azure but can handle both on site and off site backup/recovery procedures.
