The Storage Networking Industry Association (SNIA) hosted the 10th Storage Developer Conference (SDC) in the Hyatt Regency in beautiful Santa Clara, CA (Silicon Valley) on the week of September 16th 2013. This week, the presentation slides were made publicly available. You can find them all at http...

Introduction This blog post focus on the new SMB Scale-Out Rebalancing introduced in Windows Server 2012 R2. If you haven’t seen it yet, it delivers a new way of balancing file clients accessing a Scale-Out File Server. In Windows Server 2012, each client would be randomly directed via...

Windows Server 2012 R2 introduced a new version of SMB. Technically it’s SMB 3.02, but we continue to call it just SMB3. The main changes are described at http://technet.microsoft.com/en-us/library/hh831474.aspx . With this new release, we made a few changes in SMB PowerShell to support the new...

1. Overview In this document, I am sharing all the steps I used to create a demo or test environment of a storage space with storage tiers on Windows Server 2012 R2 Preview so that you can experiment with some of the new technologies yourself. You need only a single computer with one SSD and one...

This post is a part of the nine-part “ What’s New in Windows Server & System Center 2012 R2 ” series that is featured on Brad Anderson’s In the Cloud blog. Today’s blog post covers Windows Server 2012 R2 Storage and how it applies to the larger topic of “Transform...

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 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...

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...

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...

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...

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$, FST2.Test\FST2-HV2$...

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...

1. Overview 1.1. Introduction Windows Server 2012 provides Windows PowerShell cmdlets and WMI objects to manage SMB File Servers and SMB File Shares. These new tools are aimed at both System Administrator and Developers. 1.2. Benefits SMB PowerShell cmdlets allow an IT Administrator...

One of the preferred methods for creating VMs in a shared environment is to have one or more base VHDs that you use as a template for new VMs. While having a base VHD is a constant, there are a few different methods to choose when you implement your provisioning process for new VMs. This post looks at...

1. Overview Some time ago, I was automating a few tasks with PowerShell and needed to set NTFS permissions on a folder. I was tempted to use the good old ICACLS.EXE command line, but I wanted to keep it all within PowerShell. While there are a number of different permissions you could want to set...

I recently blogged about the PowerShell cmdlets included with the Microsoft iSCSI Software Target 3.3 . That included the details on all the 10 cmdlets available, including the one used to create VHD files, which is New-IscsiVirtualDisk. If you’re paying close attention to the list of new features...

1. Overview One of the new features in the Microsoft iSCSI Software Target 3.3 (included in Windows Storage Server 2008 R2) is the inclusion of PowerShell cmdlets for management. In this blog post, we will examine the details of the cmdlets available to manage targets and their associated virtual...

One of the interesting things about PowerShell is how easy it is to discover its cmdlets and parameter. In PowerShell itself or in the ISE, you can just start typing a command and then press the <TAB> key complete it. One other interesting bit is how you can use the Get-Command cmdlet to discover...

Last week I was testing Visual Studio 2010 to write a C# application to export all my blog posts to a file. I described that in some detail at http://blogs.technet.com/josebda/archive/2010/03/21/experimenting-with-visual-studio-2010-and-backing-up-the-entries-on-my-blog.aspx I am performing the exact...

If you haven’t seen it, take a look at http://blogs.technet.com/josebda/archive/2010/03/31/experimenting-with-powershell-v2-remoting.aspx . In that post, I mentioned three different ways to gather...

As I continue to experiment with PowerShell v2 in Windows Server 2008 R2, I will share some of what I learn here on the blog. This time I am focusing on PowerShell Remoting. If you never played with PowerShell before, please start by reading http://blogs.technet.com/josebda/archive/2009/07/25/experimenting...

A while back, Microsoft announced the release of PowerShell v2 for Windows XP, Windows Server 2003, Windows Vista, and Windows Server 2008 (see http://go.microsoft.com/fwlink/?LinkID=151321 ). However, it is not clear to everyone that Powershell v2 is already part of Windows 7 and Windows Server 2008...

Powershell is a command line interface for Windows that offers a very powerful and flexible model. It is now a feature included with Windows 7 and Windows Server 2008 R2, not an optional download as before. In this post, I show some sample commands that can help you understand some of the basic features...
