Prairie DevCon-What's New in Hyper-V in Windows Server "8" Beta - Part 2Damir Bersinic
This is the second of a 2-part series delivered at Prairie DevCon in Calgry on March 15. 2012. The sessions provided a quick overview of the new features of Hyper-V in Windows Server "8" Beta and how these compare to VMware vSphere 5.
This is the deck that I used at the January 2012 Hyper-V.nu event in Amsterdam, Netherlands. It focuses on the Build announced details on Windows Server 8 Hyper-V networking.
In this session we examined the Xen PV performance on the latest platforms in a few cases that covers CPU/memory intensive, disk intensive and network intensive workloads. We compared Xen PV guest vs. HVM/PVOPS to see whether PV guest still have advantage over HVM on a system with state-of-the-art VT features. KVM was also compared as a reference. We also compared PV driver performance against bare-metal and pass-through/SR-IOV. The identified issues were discussed and we presented our proposal on fixing those issues.
The client (or presentation) tier of our applications is taking on an increasingly important role. Users are expecting more compelling user interfaces, but they also want more functionality from their applications. In this ArcReady we examine how to design and deliver well architected client applications that will be easy to maintain and extend.
Session 1: Trends and patterns on the client tier
In our first session we will take a vendor and platform neutral look at some of the trends and emerging technologies that can be used on the client tier. We will look at techniques like Mashups, technologies like Natural User Interfaces (NUI) and the increasing importance of the mobile platform. We will also look at some common patterns that can be used in the architecture of the client tier.
Session 2: Applying Microsoft technology on the client tier
In our second session we will take some look at how we can use Microsoft technologies to create well architected and compelling client applications. We will look at technologies like Silverlight and WPF that can be used to create compelling clients. We will also look at technologies that can be used to make your applications more extensible for future development. We will also examine some architectural guidance developed by the Microsoft Patterns and Practices group.

We implement link virtualization based on Xen. Link virtualization is a basic building block for network virtualizaiton that allows the co-existence of different Internet protocols. To minimize virtualize overhead, we use SR-IOV with Intel 82576
Haodong Tang from Intel gave this talk at the 2018 Open Fabrics Workshop.
"Efficient network messenger is critical for today’s scale-out storage systems. Ceph is one of the most popular distributed storage system providing a scalable and reliable object, block and file storage services. As the explosive growth of Big Data continues, there're strong demands leveraging Ceph build high performance & ultra-low latency storage solution in the cloud and bigdata environment. The traditional TCP/IP cannot satisfy this requirement, but Remote Direct Memory Access (RDMA) can.
"In this session, we'll present the challenges in today's distributed storage system posed by network messenger with the profiling results of Ceph All Flash Array system showing the networking already become the bottleneck and introduce how we achieved 8% performance benefit with Ethernet RDMA protocol iWARP. We'll first present the design of integrating iWARP to Ceph networking module together with performance characterization results with iWARP enabled IO intensive workload. The send part, we will explore the proof-of-concept solution of Ceph on NVMe over iWARP to build high-performance and high-density storage solution. Finally, we will showcase how these solutions can improve OSD scalability, and what’s the next optimization opportunities based on current analysis."

AFDS Keynote: “The Programmer’s Guide to the APU Galaxy.”
Phil Rogers, AMD Corporate Fellow
It’s a well-understood maxim in the technology industry that software and hardware must evolve in parallel, and be well matched, to achieve greatness. With the introduction of the world’s first APU in January 2011, AMD pointed the world toward a new way of computing. This was very much a first step in an architectural journey that is well underway at AMD. APUs combine different processing engines in single-chip combinations to strike a unique balance between the dimensions of performance, power consumption and price. Hear how AMD is working to ease the programmer’s access to this new level of compute horsepower and dramatically expand the processing resources available to modern applications

Xd planning guide - storage best practicesNuno Alves
The Citrix Storage planning guide provides a list of best practices, recommendations and
performance related tips that cover the most critical areas of storage integration with Citrix
XenDesktop. It is not intended as a comprehensive guide for planning and configuring storage
infrastructures, nor as a storage training handbook.
Due to scope, this guide provides some device-specific information. For additional device- specific
configuration, Citrix suggests reviewing the storage vendor’s documentation, the storage vendor’s
hardware compatibility list, and contacting the vendor’s technical support if necessary
This document is an introduction to Disk Storage technologies and its terminology. Within this
document basic disk and storage architectures as well as storage protocols and common fault
tolerance technologies will be discussed. It is not intended as a comprehensive guide for planning
and configuring storage infrastructures, nor as a storage training handbook.
Due to scope, this guide provides some device-specific information. For additional device- specific
configuration, Citrix suggests reviewing the storage vendor‘s documentation, the storage vendor‘s
hardware compatibility list, and contacting the vendor‘s technical support if necessary.
For design best practices and planning guidance, Citrix recommends reviewing the Storage Best
Practices and Planning Guide (http://support.citrix.com/article/CTX130632)
This document describes how XenServer provides and keeps track of the storage supplied to its guests. The first section
is a reminder of how Linux looks at storage and the second section builds on that to explain XenServer storage. Basic
knowledge of Linux is required, as some standard tools are used.
XenDesktop relies on the hypervisor for many core functions, including VM creation, power operations, performance and redundancy. Therefore, it is important that you take the time to design an appropriate hypervisor infrastructure (XenServer, Hyper-V or vSphere). Otherwise, you may experience performance, functionality or even reliability issues.
Most information required to design a XenDesktop deployment on your chosen hypervisor platform is available publicly, but it can be hard to find since it’s spread across a multitude of knowledge base articles or white papers. In order to simplify and speed-up the design process, we’re in the process of consolidating the information that you need into a single document and augmenting it with recommendations and best practices. We’ve just finished incorporating the Hyper-V 2008 R2 and SCVMM 2012 planning section into the latest release of the Citrix Virtual Desktop Handbook, which includes important design decisions relating to this hypervisor, for example:
Selecting and sizing the right physical hardware for virtual machines
Knowing what storage options available for Hyper-V 2008 R2
What type of networks to build on the Hyper-V host
How to size the SCVMM servers
Designing a highly available SCVMM solution
Planning an effective failover cluster
The products covered in this current release of the handbook include XenDesktop 5.6, XenApp 6.5, Provisioning Services 6.x and XenClient Enterprise 4.5. A version of the Virtual Desktop Handbook covering XenDesktop 7.x, Provisioning Services 7, Hyper V 2012 R2 and SCVMM 2012 R2 is in the works with an initial release scheduled later in Q4. As always your feedback is welcomed.

Editor's Notes
The SDX is based on the Netscaler SDX hardware we already have but had been modified to meet the additional requirements of WAN optimization. A single instance of Netscaler VPX is used to Load Balance up to 6 Repeater VPX instances. Additional hardware has been added to the base SDX platform as an example additional memory and SSD drives have been added to meet the requirements of compression and other Repeater processes. A pay to grow architecture continues the trend of Citrix network appliances for flexibility and growth.
Several market drivers have led to a requirement for increased capacity. Leading the charge is the continuing migration to Xen Desktop with it’s increased requirements for BW. Server consolidation in the large enterprise have led to increased WAN Bandwidth requirements as well as an application performance issues that WAN optimization help smitigate . Overall we are seeing a growing demand from the large enterprise for WAN optimization that our current product set cannot address.

The Repeater SDX architecture should be familiar since it is based on the same principles as the Netscaler SDX platforms. The Repeater uses a Netscaler image to Load Balance 3 Repeater VPX images in the 11505 and 6 in the SDX 13505. Policies in the Netscaler distribute traffic evenly among the virtual repeaters ensuring that no single image is over subscribed. There is a service VM for management everything running on the Citrix SDX purpose built Hypervisor. Most management functions can be accomplished through the Service VM but there are requirements for management at the VM level.. This hypervisor enables SDX to take full advantage of the under lying hardware.

Based on the tried and tested Corinth 11500 and 13500 hardware platforms. Significant changes have been made to accommodate the demands of Optimization. Additional storage capacity comprised of 48 GB of ram and 2.6 TB of SSD have been added. The addition of SSD significantly improves the performance of Disk based Compression. The additional available ports and the Netscaler capabilities add some flexibility to the deployment of the Repeater SDX. We now have 10GigE ports as well as Eight 1GigE ports up from 4 ports in the 8000 series appliances. It is important to note that Fail to Wire has not yet been implemented into the SDX but that we can use the HA mode available in Netscaler for Failover. We can also use many of the other advanced features of Netscaler to assist in deployment in complicated network environments environments.

Selling the SDX is a technical sale that requires the right information to not only select the right appliance but to set the customer expectations for success. BandwidthFind out the bandwidth so you can start the process of selecting the right applianceRemember that Bandwidth is just the first step do not stop thereXA and XD have very different BW requirements on average XA uses 45k to 75k per user while XD can use 225k. This is a significant differenceTCP ConnectionsWhile the Repeater on NS SDX has tremendous capacity for TCP connections ICA uses more SDX resources plan accordinglyNetwork DiagramMost problems happen during the installation phase Diagrams leave no doubtApplication ListKnow what the critical apps are it is information that will help set expectations for performanceIn PBR mode the route policy will determine what is sent to the SDX
It is important to counsel with the customer to select the right deployment method this is of particular importance since there are some limitations to remember.There is no fail to wire cardWCCP is not currently supportedCare must be taken to size the deployment correctly. Of particular note is the number of maximum Concurrent ICA connections.A routed installation is preferred for reasons of HA and failure of the data path in case of hardware failure. No FTW means that if the SDX fails then connectivity is lost to the WAN. WCCP is not available in the current release So PBR is the only out of line option. Fortunately there is flexibility for physical connectivity with both 10 Gig and 1 gig interfaces available. Internally the virtual network connections between the Netscaler VPX and the repeaters is one armed and do not directly affect the external connectivity. A fully redundant configuration would include multiple Repeater SDX appliances using the Integrated Netscaler to manage failover. What happens when the capacity requirements exceed the capabilities of a single SDXAlways “one-armed” internally (only one interface required), but the SDX as a whole can be deployed in inline or virtual inline mode.No bypass support. The appliance will not pass traffic until it is fully configured. Production use of inline mode will cause an outage. Routed mode preferred as it is more reliable. Management functions for all VMs use the management port 0/1.
The combination of Netscaler and Repeater SDX give us incredible flexibility regarding capacity. This drawing illustrates the routed mode capability to grow beyond the capacity of a single appliance. A Netscaler can load balance multiple Repeater SDXs. Using Repeater SDX 13505 this simple configuration can Optimize8000 Concurrent ICA connections240,000 concurrent TCP connections2GB of BandwidthUp to 1Gb of CompressionAs an example the same 8000 configuration would only yield 300Meg of compression.
