Editor's Corner

In last week's newsletter I mentioned Five Things You Should Know About Windows Server 2012 R2. This week I'll give you Five More Things to think about concerning this new platform. As for the link to this week's comic, you'll find that in the Mailbag.

New Books on Hyper-V

Just a quick personal note--my two latest books have now shipped, and you can read about them in the following two posts on the Microsoft Press blog:

RTM’d today: Optimizing and Troubleshooting Hyper-V Storage
http://www.wservernews.com/go/1374228705227

RTM'd today: Optimizing and Troubleshooting Hyper-V Networking
http://www.wservernews.com/go/1374228709805

Two things you should know concerning these books. First, I was only the editor for these titles--almost all of the content was contributed by experts who work at Microsoft including Support Escalation Engineers, Premier Field Engineers, and experts from Microsoft Consulting Services. And second, these titles are not intended to be systematic guides for optimizing and troubleshooting Hyper-V networking and storage. Instead, they are mostly a collection of different troubleshooting scenarios, optimization tips, and some scripting examples.

Anyways, enjoy.

P.S. In the Tech Briefing section of this newsletter there's a link to an excerpt from my second book on WindowsNetworking.com.

From the Mailbag

A reader named Rob from Athens, Greece, sent me the following short comment concerning last week's issue:

You seem to be in love with R2.

Hey, I can't help it if I think R2 is pretty cool, even kinda hip. In fact, I guess you can call me an R2 hipster.

Now I know in some circles it's not cool nowadays to be called a hipster. In fact, as the following XKCD comic illustrates, it's getting harder and harder every day for us hipsters:
http://www.wservernews.com/go/1374228716274

But seriously, I do get a buzz over server technologies. Things like ODX, RDMA, SR-IOV, even ReFS, turn me on. I can stare for hours at Performance Monitor collecting counters measuring throughput and working set memory. I love building storage pools with different types of disks to see how the IOPS differ. I can be endlessly fascinated drilling into captured traffic using Network Monitor. And when I'm bored, I'll view websites with a Telnet client instead of a web browser.

OK that's an exaggeration. Actually it isn't. My point is that everything server-related turns me on. Whether it's server hardware, operating systems, networking, or storage, I get excited about them all. I try to learn everything I can about the latest server technologies because, well, I don't really know why--I guess it's just the way I am. Maybe it has something to do with the fact that I used to be a Physics nerd. I was originally planning on getting a Ph.D. in Astrophysics, probably because when I was young I wanted to know the meaning of life and all that. Perhaps that's why server stuff interests me--the back end is where the action is and it's usually hidden, unlike the front end.

I guess I'm a back end kind of guy...

By contrast, end-user client type of stuff doesn't nearly interest me as much. Clients are just a tool to get stuff done. I don't play with them or tweak them or customize them, I just use them. Servers are different however--they can be tuned, tweaked, optimized in various ways, and the more effort we put into tuning them the better everything works, including the clients.

To illustrate further, compare my reactions to Windows 8.1 and Windows Server 2012 R2. Windows 8.1 interests me because it changes the paradigm of how end-users will use their computers. What interests me though is not so much the software itself as the question of what today's end-users need in a computer's user interface. So it's the idea of Windows 8.1 that interests me more than the operating system itself. But it's really more intellectual curiosity than actual interest.

Then there are the back end issues associated with Windows 8.1, such as customizing a Windows 8.1 desktop image, deploying Windows 8.1 on UEFI hardware, new Group Policy settings for Windows 8.1, managing servers from an administrator workstation running Windows 8.1, and so on. Those things interest me more than the UI enhancements in Windows 8.1. Why? Because they're admin stuff, not end-user stuff.

I guess it's obvious from this that there's no way I'm half as excited about Windows 8.1 as I am about Windows Server 2012 R2. Not even one-quarter. Maybe that's why I'm the editor of a newsletter about Windows Server instead of one on client Windows? What do you think? [email protected]

But this Mailbag response from me is starting to sound a lot like an editorial, so let me quickly tell you Five More Things You Should Know About Windows Server 2012 R2. And why should you know about them? Because they're cool!

Windows Server 2012 R2 Preview - Part 2

First, a quick summary of the First Five Things from the previous newsletter R2 Preview - Part I (Issue #938):

Now here are Five More Things:

Thing Number SIX: Data dedup on CSV

Data deduplication was introduced in Windows Server 2012 to help enterprises cope with exponentially increasing growth of data storage in their environments and allows Windows Server 2012 to store more data in less physical space to optimize the capacity of their storage fabric.

Unfortunately data deduplication in Windows Server 2012 was incompatible with cluster shared volumes (CSV) so it couldn't be used to optimize storage of virtual machine files stored on a Scale-out File Server (SoFS). But with Windows Server 2012 R2, this limitation has now been removed, and turning on deduplication for CSV volumes can enables space savings as high as 90 percent on them--wow!!

Thing Number SEVEN: Shared VHDX

Hyper-V in Windows Server 2012 R2 now allows guest clustering using shared VHDX files. Yippee!

What does this mean? For hosters, it means they can offer Hyper-V guest clustering to customers while keeping the hoster's physical infrastructure layer (computer, storage, and network) and virtualized resources (tenant virtual machines and the workloads running on them) isolated from one another.

How does this work? Guest clustering using shared VHDX allows the hoster to provide guest clustering to customers without the need of providing direct access from the tenant's clustered virtual machine to a LUN on the hoster's Fibre Channel SAN.

Thing Number EIGHT: Virtual RSS

In Windows Server 2012 a technology called Receive Side Scaling (RSS) allows kernel-mode network processing to be spread across multiple cores in a multicore server system. This can be useful in many environments because today's enterprise-grade NICs can be that a single processor core of the server won't be able to make full use of the NIC's throughput capability. But in Windows Server 2012, virtual machines were limited to using only one virtual processor for processing network traffic. As a result, virtual machines running on Hyper-V hosts were unable to make use of RSS to utilize the highest possible network traffic loads.

But in Windows Server 2012 R2 with a new feature called virtual RSS (vRSS), the network processing for a virtual machine can now be spread across multiple virtual processors inside the virtual machine and also inside the host. The physical NIC can now spread traffic among available cores inside the host, while the virtual NIC distributes the processing load across the virtual processors inside the virtual machine. The result is that vRSS now makes it possible to virtualize network-intensive physical workloads that were traditionally run on bare-metal machines. This now enables a whole new range of virtual workloads that can perform as well as physical workloads. Examples might include virtual network appliances, virtual gateways, and virtual file servers.

Thing Number NINE: Dynamic Site Activation

This one is for IIS geeks. My first book was about IIS and was called Administering IIS 4. You can still buy it used on Amazon Marketplace for one cent:
http://www.wservernews.com/go/1374228725462

One of the key scalability goals Microsoft has for IIS 8.5 in Windows Server 2012 R2 is enabling cloud hosting providers to host more sites on a single IIS server. In Windows Server 2012 and earlier, when IIS starts up on a host the Windows Activation Service (WAS) loads the entire configuration for IIS. This configuration can be very large if several thousand sites are being hosted on the server, which is typical in many hoster environments. Because of this, loading the IIS configuration can consume a lot of memory on the server, which can impact the performance of other options such as initializing worker processes for web applications.

To address this issue, the WAS component has been redesigned in IIS to better handle large configurations and improve the memory efficiency of the IIS startup process. In addition, the HTTP protocol stack (Http.sys) now uses a single catch-all request queue and binding to be used by WAS for initializing the worker processes associated with each of the sites running on the IIS server. The result of this change is that when WAS starts up, it no longer has to create thousands of request queues and bindings in Http.sys—one for each of the thousands of worker processes associated with each of the thousands of sites running on the server. The WAS component can now examine a client request in this queue and determine which site and worker process should handle that request. WAS then creates a queue for the request, registers the binding, and spins up the worker process for the site to start the site.

This new functionality is called Dynamic Site Activation, and it addresses the issue of being "config-bound" which hosters who run large numbers of sites on IIS servers can experience.

Neat, eh?

Thing Number TEN: Shadowing remote sessions

A frequent request from Microsoft customers who use Remote Desktop Services (RDS) is to add the ability for administrators to shadow the sessions of remote users. Such shadowing capability is now included in Windows Server 2012 R2. To see how this works, the figure below shows the connections in Server Manager to a Remote Desktop Session Host running Windows Server 2012 R2. In previous versions of RDS, if you right-clicked a remote session you only got three options: Disconnect, Send Message, and Log Off. But in RDS in Windows Server 2012 R2 there is now a fourth context menu option called Shadow, which enables administrators to shadow the session of a connected remote user:

Image

Selecting the Shadow option opens a dialog box that lets you choose between allowing the administrator either to view only or to view and take control of what the remote user is doing in his session. So if you ever thought that your administrator acts as though he's "the police" for your network, well you're right:

Every breath you take
Every move you make
Every bond you break
Every step you take
I'll be watching you
