Hi Folks -
In my previous post, I listed my favorite storage improvements in Windows Storage Server 2012 R2. In the next few blog posts, I will focus on providing a bit more detail on these storage improvements. This post covers the protocol layer changes, exploring the improvements we’ve made to SMB and the iSCSI Target Server. SMB
SMB 3.0, which was delivered with Windows Server 2012 in September 2012, included enhancements such as SMB Direct, SMB Multichannel, and SMB Scale Out. These improvements made SMB a compelling means of storing Hyper-V VMs and SQL Server databases on cost-effective, easily deployed file shares, thereby reducing the need for more costly and complicated Fibre Channel storage.
The newly refined version of SMB 3.0 that is included in Windows Storage Server 2012 R2 builds on many of the innovations we introduced a year ago to provide an even better protocol for the storage of application data. New and improved features in the latest version of SMB include:
More information on what’s new for SMB in Windows Server 2012 R2 can be found here.
Microsoft began including the iSCSI Target Server as an optional add-on for Windows Storage Server 2003 and included it in-the-box with Windows Unified Data Storage Server 2003. After eight years of continuous improvements, the iSCSI Target Server is mature, stable, and reliable.
Now that the iSCSI Target Server is included in all editions of Windows Server 2012, it’s a great way to provide raw block storage for application servers. The iSCSI Target can also be used to boot an entire farm of diskless HPC servers or diskless datacenter servers, with a regular network adapter from a single master operating system image, leveraging differencing VHDs to create hundreds of iSCSI boot images on the fly.
Enhancements to the latest version of the iSCSI Target Server include:
A great blog article that goes into more depth on enhancements to the iSCSI Target Server can be found here.
With SMB 3.0 and the iSCSI Target, whether you need file or block access, Windows Server 2012 R2 is ready to deliver. The new SMB storage enhancements make it a top-tier storage protocol—and make Windows Storage Server 2012 R2 a great storage solution for hosting your VMs and SQL databases. The iSCSI Target is just as easy to quickly deploy and configure, without advanced skills in storage management. I can’t wait to see new storage solutions based on these technologies come to market later this year!

With the new SMB, Have you seen issues with server 2012 r2 connecting to a buffalo terastation nas, that is running SMB 1.5?
I am trying to deploy these units, on my network, and my 2012 server can connect to the NAS but none of the 2012 r2 severs can connect to it.
