In this post, I'm providing a reference to the most relevant content related to Windows Server 2012 that is related to the File Server, the SMB 3.0 features and its associated scenarios like Hyper-V over SMB and SQL Server over SMB. It's obviously not a complete reference (there are new blog posts every...

A Scale-Out File Server is a cluster role that offers the same SMB file share (or set of shares) on every node of the cluster. As clients come in, they are spread across the nodes using a round-robin mechanism based on DNS. In the common case of having many clients and just a few file server cluster...

I was visiting the expo area at MMS 2013 earlier today and saw that Iron Networks was showing a private cloud pod there, complete with a set of well-matched layers of compute, storage and networking. They were demonstrating several of the latest capabilities in Windows Server 2012 and System Center...

I have been working with Bob Hunt at the TechNet Radio team to provide a series of webcasts with information about SMB 3.0 and the File Server role in Windows Server 2012. These are fairly informal conversations, but Bob is really good at posing interesting questions, clarifying the different scenarios...

Overview I delivered a demo of Hyper-V over SMB this week at MMS 2013 that’s an evolution of a demo I did back in the Windows Server 2012 launch and also via a TechNet Radio session . Back then I showed a two physical servers running a SQLIO simulation. One played the role of the File...

I delivered an instructor-led lab on Windows Server 2012 Storage at MMS 2013 yesterday (4/8), with a repeat scheduled for tomorrow (4/10) at 2:45 PM. You can find the details on this lab at http://www.2013mms.com/topic/details/WS-IL303 I used a few slides to comment on the contents of the lab, with...

Question via e-mail: I am using blade servers for my Hyper-V cluster and I can only have two NICs per blade in this configuration. I am considering two options on how to configure the NICs: 1) Use one NIC for internal network and one NIC for external network, connected to the virtual switch...

Question received via e-mail: Is it practical use SMB3 storage without RDMA or do we have a use case for production rather than development or test? I thought RDMA would be essential for production deployment of Hyper-V SMB storage. Answer: RDMA is not a requirement for the Hyper-V over SMB...

Question received via blog mail: Jose- I picked up a couple ConnectX-2 adapters and a cable off of ebay for cheap (about $300 for everything) to test out SMB Direct. I followed your blog "Deploying Windows Server 2012 with SMB Direct (SMB over RDMA) and the Mellanox ConnectX-2/ConnectX-3 using...

1. Introduction I have been doing storage-related demos and publishing blogs with some storage performance numbers for a while, and I commonly get questions such as “How do you run these tests?” or “What tools do you use to generate IOs for your demos?”. While it’s...

Introduction Increasing availability is a key concern with computer systems. With all the consolidation and virtualization efforts under way, you need to make sure your services are always up and running, even when some components fail. However, it’s usually hard to understand the details...

Highly available Windows Server 2012 systems using shared, directly-attached storage can be built using either Storage Spaces or a validated clustered RAID controller. Option 1 – Storage Spaces You can build a highly available shared SAS system today using Storage Spaces. Storage...

1. Introduction   If you follow this blog, you probably already had a chance to review the “Hyper-V over SMB” overview talk that I delivered at TechEd 2012 and other conferences. I am now working on a new version of that talk that still covers the basics, but adds brand new segments focused on end...

This post describes a few different Hyper-V over SMB sample configurations with increasing levels of availability. Not all configurations are recommended for production deployment, since some do not provide continuous availability. The goal of the post is to show how one can add redundancy, Storage Spaces...

These are some PowerShell snippets to configure a specific set of systems for Hyper-V over SMB testing. Posting it here mainly for my own reference, but maybe someone else out there is configuring a server with 48 disks split into 6 pools of 8 disks. These systems do not support SES (SCSI Enclosure Services...

There are two blog posts explaining in great detail what you need to do to use Mellanox ConnectX-2 or ConnectX-3 cards to implement RDMA networking for SMB 3.0 (using SMB Direct). You can find them at: Deploying Windows Server 2012 with SMB Direct (SMB over RDMA) and the Mellanox ConnectX-3 using...

One smart MVP was doing some testing and noticed that SMB Multichannel did not trigger immediately after an SMB session was established. So, he asked: How much traffic needs to pass between the SMB Client and Server before Multichannel actually starts? Well... SMB Multichannel works slightly different...

Question from a user (paraphrased): When we access a local file via loopback UNC path, is this the same as accessing via the local path? I mean, is "C:\myfolder\a.txt" equal to " \\myserver\myshare\a.txt " or I'll be using TCP/IP in any way? Answer from SMB developer: When accessing files over loopback...

If you're an IT Administrator, you're likely to use the new SMB PowerShell cmdlets to manage your SMB 3.0 file shares. You can find details about those at http://blogs.technet.com/b/josebda/archive/2012/06/27/the-basics-of-smb-powershell-a-feature-of-windows-server-2012-and-smb-3-0.aspx However, if...

I got a question the other day about one of the scripts I published as part of a step-by-step for Hyper-V over SMB , Here's the relevant line from that script: New-SmbShare -Name VMS3 -Path C:\ClusterStorage\Volume1\VMS -FullAccess FST2.Test\Administrator, FST2.Test\FST2-HV1$, FST2.Test\FST2-HV2$...

There is a new ESG report out that shows the Storage and Networking performance of Windows Server 2012. It highlights the findings around a few key new features, including: Storage Spaces SMB 3.0 File Servers Deduplication CHKDSK Online Scanning Offloaded Data Transfers (ODX) The numbers speak for themselves...

Windows Server 2012 and Windows 8 include a new set of performance counters that can greatly help understand the performance of the SMB file protocol. These include new counters on both the server side and the client side. In this post, I wanted to call your attention to the new client-side counters...

A while back, I showed how to use PowerShell V2 and our old SMB WMIv1 object to explain how to find the free space behind a file share (essentially the free space for the volume that contains the file share). That post is available at http://blogs.technet.com/b/josebda/archive/2010/04/08/using-powershell...

Windows Server 2012 includes a built-in mechanism called Best Practices Analyzer (BPA) to check your configuration and make sure everything is set to the proper values. These set of rules, which come in specific sets for each role you install, can be run through Server Manager or also via PowerShell...

When deploying Hyper-V over SMB (storing your live configuration and live VHD/VHDX files on an SMB 3.0 file share), make sure you don’t use a loopback configuration. A loopback configuration means that the Hyper-V role and the File Server role are on the same computer. While you can actually have both...
