    Monitoring Ubuntu Servers with OpenManage Essentials

    Recently, in response to a user question in the TechCenter forum, Dell Linux Engineering's on-site field engineer from Canonical, Kent Baxley, wrote detailed instructions on how to use OpenManage Essentials to begin monitoring PowerEdge systems running Ubuntu Server. The steps he outlines allow OpenManage Essentials to discover and monitor a system running Ubuntu Server 12.04 and OpenManage System Administrator 7.1. Kent's instructions are available on the TechCenter wiki at:

    While OpenManage System Administrator and OpenManage Essentials are not currently supported by Dell with Ubuntu, and it is not currently possible to use them for firmware updates on Ubuntu, I believe that this is still valuable to anyone needing to monitor their PowerEdge servers running Ubuntu 12.04. Together with Landscape from Canonical for managing the OS in addition to wsmancli and wsl for interfacing with the Lifecycle Controller on PowerEdge 12G, there is an ever-growing number of tools for those needing to manage their PowerEdge servers running Ubuntu.

    Back to the Future – London Clouds #SharePoint #spevo13 @cmcnulty2000

    Earlier this month, Dell Software was a proud sponsor, again, for the SharePoint Evolutions conference at the QE2 Conference Center at Parliament Square in London. Despite being across the street from Westminster Abbey, the Houses of Parliament, “Big Ben” (Elizabeth Tower) and the Margaret Thatcher funeral procession (below), there was a lot of fascinating news coming out of the conference. And clouds, clouds, clouds.

    Procession, © 2013 Christopher F. McNulty on Flickr

    Two strong trends emerged throughout the week at sessions and at our booth. First, there’s a groundswell of interest in SharePoint 2013 and Office 365. To sum up, there’s good awareness that Dell Software’s been leading the way with migrations to SharePoint Online and Office 365 using Migration Suite for SharePoint. Similarly, we released one of the earliest management reporting tools for Office 365 over a year ago as part of Site Administrator. Finally, our Dell Social Hub has been a pioneer in apps for Office 365 on the Microsoft Store, helping pave the way for more online customization soon, drawing on our experience with Quick Apps for Sharepoint.

    There was a LOT of interest in moving to SharePoint 2013 this year. And in general, I’d say customers are preparing themselves to move to Office 365 during the next two years, and are working to align their project roadmap with Microsoft and ISVs like Dell. It’s a much more pro-cloud vision than I’ve heard at prior events.

    There is also a lot more interest in custom apps on the SharePoint platform – with in the box capabilities, with custom code, and increasingly with tools like Quick Apps.

    Finally, although web-based file storage has been one of SharePoint’s strong points since 2001, that’s not unique anymore. What distinguishes SharePoint is pairing its strong content management with at least one other workload – apps, social, search, workflow, forms, or business intelligence are frequently mentioned.

    Many thanks to the entire Dell team, especially Jo Radomska for all out event support throughout the week. Special thanks also to Steve Smith and the Combined Knowledge team for another strong event. Our presentation “SharePoint 2013 – Why Migrate, How to Get There, How to Stay There” is also available at

    Phi …, Nodes, Sockets, Cores and FLOPS, Oh, My!

    Intel’s Xeon Phi coprocessor is the subject of this latest blog, which has evolved into a bit of a series of blogs.  In the most recent post, I described how to compute the peak theoretical floating point performance of a system hosting GPUs.  That one followed a general purpose description of computing peak floating point performance of systems containing CPUs such as Xeon processors from Intel.  



    Intel’s Xeon Phi coprocessor, unlike GPUs, is based upon the same architecture as the Intel Xeon CPU, such as Westmere, Nehalem, Sandy Bridge and the upcoming Ivy Bridge.  As such, computing the peak theoretical floating point performance is similar to computing it for CPUs as described in the first blog.

    There are several public references available that indicate that the currently shipping Intel Xeon Phi model 5110 contains 60 cores and that they operate at 1.053-GHz.  Unlike GPUs where all cores are not available for double precision floating point math, all 60 cores of Intel’s Xeon Phi are available and computing the peak double precision floating point performance is as straight forward as it was for regular Intel CPUs. 

    All 60 of these cores can perform double precision floating point math at a rate of 16 flops/clock. Yes, sixteen(16) flops/clock!  The AVX in Xeon Phi is one generation ahead of the AVX in general purpose Intel processors. (Comparing and contrasting these 60 cores at 16 flops/clock to a GPU’s 1000-ish cores at 2 flops/clock may be the subject of a future blog.)   

    Here’s the peak theoretical floating point math for an Intel Xeon Phi 5110:

    GFLOPS  =  60 cores/Phi  *  1.053 GHz/core  * 16 GFLOPs/GHz

    GFLOPS  =  1,010.8

    I have seen this appear as “over a teraFLOP”  and as 1,011 GFLOPS.

    Additionally, the TACC Stampede system uses a special edition of the Intel Xeon Phi called the SE10.  It features 61 cores operating at 1.1-GHz.

    GFLOPS  =  61 cores/Phi  *  1.1 GHz/core  * 16 GFLOPs/GHz

    GFLOPS  =  1,073.6

    For additional information about TACC and the Stampede systems see:

    Hope that helps.  As future Intel Xeon Phi models are released in the coming months, these same type computations should be valid to compute their peak performance.  For a system, compute the CPU performance of the host node as described in the previous blog.  Compute the Intel Xeon Phi performance as described here.  The total system performance is the sum of these.     

    Remember that this is the peak theoretical floating point performance. This is the theoretical performance you are guaranteed to never see.  Expect to see more about real-world performance using Intel Xeon Phi as the Centres of Competence come up to speed:

    If you have comments or can contribute additional information, please feel free to do so.  Thanks.  --Mark R. Fernandez, Ph.D.

    5 Ways #SharePoint 2013 is like a new puppy, including peeing on the floor

    So you're thinking of upgrading to SharePoint 2013. We all know the benefits. Blah, blah, blah I don't need to do Microsoft's job and evangelize what we already know about social, the app store, search, etc. Its all cool. You just get it. But do you just get what it takes to manage this new 2013 environment? Do you know what 2013 provides natively in terms of reporting, security, storage management, backup and recovery and user adoption?

    Let's put it another way, managing SharePoint 2013 natively is a lot like managing a brand new puppy.

      In fact, here are my top five ways SharePoint 2013 management is a lot like managing a new puppy:

    1. Reporting: Puppies pee all over the floor and it dries before you can figure out where it happened, just as SharePoint content gets propagated hither, thither and yon across SharePoint without any good native user or content reporting.
    2. Security: Puppies have never met a stranger they didn't lick and immediately let into the house and neither has your SharePoint.
    3. Storage Management: Puppies put on weight and get lazy when you give in to their cute puppy eyes and feed them table scraps, just like SharePoint packs on the pounds and slows down with increased usage.
    4. Backup and Recovery: Puppies love to hide their bones, but they're loveably dumb and lose track of their hiding places, just as SharePoint loses data and you can't figure out which backup you need.
    5. User Adoption: Puppies don't learn to sit, lay down or speak without assisted encouragement (a.k.a. treats) just like SharePont users can't break the cycle of collaborating via Outlook to collaborate via SharePoint.

    I'm totally a dog lover (in fact the lovable pooch seen in this post belong to yours truly) just as I am a fan of SharePoint 2013. But just like bringing in a new puppy into your house, you need to know what comes natively with SharePoint 2013 management and where third party tools, like those from Dell, come in to assist!

    Chris McNulty (@CMcNulty2000), Dell Software CTO, has prepared an excellent webcast to review what you can expect to get with SharePoint 2013's native management functions and where Dell SharePoint solutions for management fill the gaps. Check it out here and sign up today!

    Choosing the Right Tools for SharePoint 2013 Management

    Type: Webcast Date: Wednesday, May 1, 2013 Time: 2 p.m. ET/11:00 a.m. PT

    Organizations are finding compelling reasons to adopt or upgrade to SharePoint 2013. The platform includes a variety of new and enhanced functionality for end users, but many organizations are still unsure how to manage the new platform. In this live webcast, Chris McNulty, Dell Software CTO, will explore several tools that make SharePoint 2013 management easier than ever before.

    Dell vWorkspace 8.0 Feature Spotlight: User Experience Monitoring (part 2)

      User Experience Monitoring - Part 2

    Welcome to part 2 of the feature spotlight in a series where we will discuss the new User Experience Monitoring feature in Dell vWorkspace 8.0

    As you know, a great end user experience is a critical part of desktop virtualization success. In fact, it can make or break a desktop virtualization project. That having been said, when the user experience is falling short of expectations (i.e., inferior to the experience offered on a physical desktop) becomes very important to resolve the issue as quickly as possible. So, in Dell vWorkspace 8.0 we introduce a completely new feature called User Experience Monitoring. This feature was designed from the ground up to help customers get to the bottom of user experience issues as fast as possible. Not only in real-time, but also for user experience problems that occurred in the past.

    In part 1 we discussed the 'Connection Information' and the 'Connector Information' section of the User Experience Monitoring feature. Now's lets continue with some of the other sections.

    EOP Information

    Dell vWorkspace for more than 10 years has been adding value to Microsoft technologies and in particular RDP. Our technologies that add value to RDP are known as EOP (Experience Optimized Procotol). To effectively troubleshoot any user experience issues, it is of vital importance to know which EOP features are in use. Enter the EOP Information section of the User Experience Monitoring feature in Dell vWorkspace 8.0. The Connection Information section of the User Experience Monitor was specifically designed to provide just that information. See the screenshot below.

    Across the board this section of the User Experience Monitoring feature really shows if the feature actually is in use. For example: if you are have configured EOP USB to be allowed on both the client and the server but you are not redirection a USB device, this means that the status will show as 'OFF'.

    • EOP Xtream: shows you whether or not EOP Xtream is in use. Very important to know if you notice that a customer is connection over a highly latent network. EOP Xtream aaccelerates RDP and EOP traffic on wide area networks (WANs). This provides for an improved user experience by providing faster RDP screen responses and improved performance of all EOP features.
    • EOP Audio: indicates if a EOP Audio is in use. EOP Audio is a collection of technologies that enables support for applications that require the use of a microphone, such as dictation, collaboration, and certain Voice Over Internet Protocol (VOIP) applications such as Office Communicator, Lync or other VOIP application by vendors such as Cisco and Avaya.
    • EOP Graphics Acceleration: tells you if the user is actively using EOP Graphics Acceleration. EOP Graphics Acceleration can significantly reduce bandwidth consumption and dramatically improves the user experience ,especially for older version of RDP.
    • EOP Multimedia Flash Acceleration: this is a so called 'combined metric'. It will show you whether if the customer is using either one or both of our multimedia acceleration technologies (we have one for Windows Media and one for Flash specifically).
    • EOP Text Echo: shows you if EOP Text Echo is in use. EOP Text Echo enhances the user experience when typing if they are connecting over a high latency network connection.
    • EOP USB: this section of the User Experience Monitor will tell you wether or not a USB device is actively being redirected. EOP Universal USB enables the use of virtually any USB connected device, such as PDAs, local printers, scanners, cameras, and headsets to be used in conjunction with VDI.
    • EOP Print : finally, the EOP Print section tells you if EOP Print is being used. EOP Print really is a set of features around printing that we specifically designed for one goal only: to just make printing work seamlessly in a SBC/VDI environment.

    Managed Applications Information

    This section of the User Experience Monitor will allow you to see which Managed Applications are in use on a given RD Session Host.

    It list all of the Managed Applications. If there is a large number of managed applications, the search bar will easily help you locate it. Because of vWorkspace's Session Sharing feature the likelihood is very big that each managed application will be opened on the same RD Session Host. In case this does not happen, the Managed Application will not show up in the same view (because that makes it a different session). The Managed Application section of the User Experience Monitor will also show when the managed application was launched. Only Managed Applications of the type 'Program' are currently monitored.

    CPU and Memory Consumption Information

    Especially on a RD Session Host it is extremely important to have accurate insights into the utilization of the two most important resources: CPU and Memory. That's actually what this section of the User Experience Monitor was designed for:

    On the top we show historical charts of the utilization of CPU and memory - in the context that matters: we show you how the CPU and memory utilization of this user compares to the overall utilization on the server. This is important so you can find out if this user is monopolizing the server because that could have a negative effect on the user experience of other users on the same server. The bottom half of this section of the User Experience Monitor show you the top 5 CPU and Memory consumers. Managed Applications are easily identified with a special icon. So in this example, we can see that Outlook 2013 has the largest working set (the memory metric that counts the most in this context) but it does not even show up in the CPU top 5. Finally, it is worth noting that Managed Application metrics shown in the User Experience Monitor are always inclusive of any system resources consumed by child processes. This is very important because it is not uncommon for Managed Applications to spawn child processes that are a part of the Managed Applications and administrators need to take those child processes into account in whatever they do, especially when monitoring the user experience. If you want to find out which child processes a Managed Application is made up of, it is very easy to do so from the details tab of the User Experience Monitor.

    During the next couple of weeks we will discuss these and all the other new functionality in much more detail right here on our blog, so make sure to stay tuned for that! In the mean time we understand that you will want to have a look for yourself. There’s nothing we’d like more. Here are some things you can do to learn more:

    That’s it for now. We hope that you are excited about Dell vWorkspace 8.0! Please let us know what you think - also using the social sharing buttons on the top right of this post.

    Dell PowerEdge C AMD servers: the most power-efficient AMD servers in the industry

    Dell PowerEdge C AMD servers: the most power-efficient AMD servers in the industry


    Dell has achieved the two highest SPECpower benchmark results for all AMD-based servers! The PowerEdge C6105, a chassis that supports four 2-socket server nodes , has scored 4510 overall ssj_ops/watt, taking the #1 power-efficiency spot among all AMD-based results.  

    Dell’s PowerEdge C6145, a chassis that supports two 4-socket server nodes, is only 11 points behind, with a score of 4499 overall ssj_ops/watt. Both of these results are more than 380 points better than the closest competitor!  

    Dell enterprise servers continue to set power-efficiency records that competitors just can’t match.

    The PowerEdge C6105 is a high-density, low cost, and extremely power-efficient AMD platform that is an ideal solution for dedicated hosting environments, Web farms or price-performance targeted clusters like Hadoop. With its small 2U form factor, the C6105 is perfect for any business, small to enterprise, where power efficiency and high performance are needed.

    The PowerEdge C6145 is a high-core density, high memory density, and extremely power-efficient server that is ideal for HPC (Large Compute, GPU), Engineering Design Assessment (Large Memory) or Film/Entertainment (Rendering) applications. With its compact small 2U form factor, the PowerEdge C6145 is for enterprise customers requiring the highest AMD performance.

    Dell continues to lead the way in power efficiency, and the PowerEdge C6105 and C6145 are the latest servers to prove it. For more information on how these SPECpower scores were achieved, check out the following whitepaper link.

    Dell SonicWALL Hosted Email Security – Initial Setup

    Dell has a new hosted service called Dell SonicWALL Hosted Email Security.  I started a series of blog posts ( and was asked to share them here.  This post will go over the initial setup of the service.

    To setup my mail services to use Dell SonicWALL Hosted Email Security, I need to take the activation key I received from Dell SonicWALL and go to the Hosted web site (  On this site I could have also purchased the service as well.  Since I have my activation key, I will click on the Activate Service button as shown below.

    Clicking this button took me to a login page for the Hosted Email service.  This ties to a account.  I did not have a account so I created one from this screen.  Once logged in, it asked me for an activation key.  This is where I put in my key and then clicked register.

    Next I was asked for a Friendly Name.  This is how your instance will show up in the hosted email security portal.  I entered what I wanted to call this instance and clicked Submit.

    Now it is time to enter more info.

    I entered my domain name:  The inbound mail server will be what my current MX record host name is.  Outbound Mail Server would be the IP that my mail server would use to connect to the hosted email service.  I left this blank for now and will fill it in later as I use Google Apps which uses a ton of IPs.  The email address is filled in for me with the format admin AT I then entered a password and chose a data center location, which in my case is North America.  After I verified the info was correct, I clicked on Activate.  A pop up box asked me to confirm that I wanted North America as my data center so I clicked Yes.

    After a successful activation, I was rewarded with a screen showing me what to change my MX record to and what to change my outbound record to so that all inbound mail will flow through the service.  I went into my web host provider DNS settings and changed my MX record to The solution started filtering my mail within 24 hours once my MX-record change propagated to all the public DNS. The outbound service of the solution is intended for organizations who own their own SMTP servers. Dell is protecting its customer’s email infrastructure with this solution.
