Troubleshoot Virtualization in All Its Guises: Server, Desktop and SDN. The benefits of virtualization are well-known and widely accepted, from cost savings and efficiency, to disaster recovery and flexibility. But it’s probably not until you are firmly on the path to virtualization that you start to think about the operational aspects. Virtualization comes in many guises; the most common is server virtualization. Virtual desktop infrastructure (VDI) – including products such as Citrix XenDesktop/XenApp or VMware View – is a close second. Software-defined networking (SDN), although in its nascence, is also under heavy scrutiny. Each of these virtualization technologies has one thing in common: they are incredibly difficult to monitor and troubleshoot. In this slide show you will learn how Riverbed Cascade 10.0 provides a single, unified interface to monitor and troubleshoot these many virtualization guises.

Hinweis der Redaktion
- This learning module discusses the new features and functionality of Cascade 10.0, includingNew support for VDIand network virtualization that makes Cascade the only solution capable of managing performance across all virtual infrastructure: VDI, server, and network virtualization How new VDI and CIFS monitoring and troubleshooting enhance the joint value between Cascade and Steelhead / GraniteIntroducing Cascade Profiler Virtual Edition and Cascade Gateway Virtual Edition, which, with the previously announced Cascade Shark Virtual Edition (formerly Virtual Cascade Shark), completes the virtualization of the product family,How and why MSPs and SIs should use the virtual solutions to drive new services around application-aware network performance managementAnd lastly, a quick overview of other important enhancements that don’t fall into any of these broad categories
- Virtualization brings with it great promise of flexibility, cost savings, and security. Most importantly it allows IT infrastructure to dynamically adapt to the needs of applications. This value comes with a cost in the form of increased complexity for Network and IT operations. With this announcement, the Riverbed® Cascade® product family extends its leadership in virtualization monitoring. It is the first and only application-aware network performance management (NPM) solution to provide comprehensive and unified visibility across the WAN, LAN, virtualized desktop and server environments, and software-defined networks (SDNs) to meet the rapidly changing needs of IT organizations. The latest version of Cascade products builds upon our announcement last February using Cascade Shark VE to gain visiblity into traffic traversing the virtual switch and adds the ability to monitor and troubleshoot Citrix XenDesktop/XenApp and VMware® View virtual desktop infrastructure (VDI) and also to embrace VMware VXLAN-based software-defined networking without sacrificing operational control. In addition, the Cascade product family is now available as a fully virtualized software solution to enable enterprises, government organizations, public clouds, and other managed service providers to easily deploy and use Cascade products in virtual environments. It enables network operations teams to find and fix network and application performance issues, no matter the architecture or where they are in their virtualization journey, including: Traditional networksVirtual desktop infrastructure (VDI)Server virtualizationFully virtualized data centers using SDNAny combination of the above
- So why is virtualization such a hot topic with us … because it’s such a hot topic with you – network managers and executives…A recent Enterprise Management Associates (EMA) survey indicates that virtualization in all forms is a top initiative with IT executives and staff. Server virtualization is once again the top initiative and virtual/hosted desktop jumped into second place in 2012. Cloud ranks pretty high up there as well.
- The problem is…y’all don’t have adequate visibility to monitor or troubleshoot problems that arise in these environments.Virtual networking deployed as part of server virtualization increasingly affects network managers, their tools, and their practices. Only 62% of respondents indicated that network engineers/operators have access to virtual network elements within virtual server environments for monitoring/troubleshooting visibility, and only 58% have access for configuration and control. As can be seen in this Figure, the situation specific to visibility into these environments has improved incrementally from early 2011 to late 2011; however, 72% of respondents still reported needing better insights.
- Virtual Desktop Infrastructure (VDI) holds the promise of simplifying IT infrastructure, management, and data security. Cascade Pilot now support ICA and PCoIP, two popular VDI protocols used by Citrix XenDesktop/XenApp, and VMware View, respectively. With this release, customers gain visibility into the virtual channels of these VDI protocols, including their bandwidth consumption and priorities. Customers can also see the latency of critical actions such as print, keystrokes, mouse movements, file sharing, and screen refreshes. Having detailed visibility into specific VDI actions is not only critical to troubleshooting issues, but is also essential for optimizing the performance of these applications across both the WAN and LAN.
- Businesses want the promise of dynamic, on-demand cloud based IT. While vSphere abstracts compute capacity from the server hardware to create virtual pools of resources that can be consumed as a service in a matter of minutes, today’s traditional network architecture prevents organizations from reaching the full potential of virtualization. Provisioning of networks and network services such as security are still cumbersome and slow and can take days to set up. Even then, the opportunity to introduce errors is extremely high and changes to shared network services can have unintended consequences.Software-defined networking (SDN) is one of the corner stones of the software-defined data center (SDDC) that is changing the paradigm of data center infrastructure. SDN allows for the quick and dynamic configuration of virtual or overlay networks, which enable the creation of a virtual data center (VDC) –an isolated collection of all necessary compute, storage, networking, and security resources – in a matter of minutes.
- VMware® Virtual eXtensible Local Area Network (VXLAN) is the key to deploying software-defined networks with the same simplicity and operational ease of virtual machines today. Because VXLAN tunnels traffic on top of the physical network, creating an “overlay network”, it separates the virtualization and network layers to enable the following benefits:Ease of network provisioning – VXLAN automatically provisions virtual overlay networks and their associated services as needed for virtual datacenters – with no impact to the physical network or involvement of the network team.Security – Virtual overlay networks are isolated from each other and the physical network, addressing security and compliance requirements while using shared infrastructure, and enabling the cost savings associated with it. Scalability – Enables virtual networks and virtual data centers to span physical boundaries, optimizing compute resource utilization across clusters, pods and even geographically separated datacenters and allowing organizations to build virtual data centers anywhere, anytime based on business needs rather than technical limitations.
- While VLXAN extends the benefits of virtualization from server workloads to entire virtual data centers, on its own it does not address the performance management challenge of virtual environments. While monitoring and troubleshooting network performance with server virtualization has been problematic enough for network operations, the introduction of virtual overlay networks compounds this even further. VXLAN traffic is UDP tunneled, creating a total loss of visibility for the network team, making it impossible to Isolate overlay traffic from physical networkManage the overlay traffic’s impact on the physical networkUnderstand tunnel and overlay network setup/tear downAdditionally, different overlay networks can have overlapping address spaces, further compounding troubleshooting.Left unaddressed, this lack of visibility can create a barrier for the adoption of VXLAN, SDN and virtual data centers.
- Realizing the ability to monitor, troubleshoot and report on network and application performance is a necessary and critical component for the full adoption of VXLAN, Riverbed and VMware have joined together to provide this capability. The two companies have jointly developed the new VXLAN-aware IPFIX format, which provides performance information about virtual overlay network traffic and associated UDP-encapsulated traffic. This new VXLAN functionality extends Cascade’s performance management capabilities from monitoring the virtual switch/VDS within vSphere to encompassing virtual data centers and their associated overlay networks. Riverbed Cascade is the only application-aware network performance management (aaNPM) solution to enable IT organizations to confidently embrace SDN by enabling network operations teams to: Control and understand virtual overlay network performanceMonitor and troubleshoot virtual data centers and the physical network in a single solutionProvide VDC owners isolated views into their virtual data center performance and SLAs
- Other NPM solutions without VXLAN visibility can only see how much VXLAN traffic is tunneled across the physical network, leaving them virtually blind when it comes to troubleshooting problems.CLICK: Cascade can provide details into top applicationsCLICK: How virtual machines (VMs) converseCLICK: How virtual tunnel endpoints (VTEPs) interactCLICK:Top virtual networks from an enterprise perspective, and more…
- In a physical network environment, it is relatively easy to instrument it so you can monitor application performance as the transaction traverses between the web server, the application server, database, etc. CLICK: Virtualization provides significant headaches for IT operations teams. Once an application transaction enters the virtualized server NetOps loses visibility into the transaction. In fact, some transactional traffic never hits the physical network so it can never be monitored. Without adequate visibility into the end-to-end application flow, IT often cannot troubleshooting problems occurring in virtualized environments.CLICK: Compounding this issue, according to Gartner, is the fact that virtual switches today are typically managed by the server administrator, which is challenging the existing separation of duties because of unclear or incorrect network responsibilities and skills related to managing virtual switches embedded within hypervisors on physical servers. Today, almost all hypervisors have limited networking capabilities. But as virtual switches adopt control features similar to physical switches, the risk of inconsistent configuration between virtual and physical switches will increase, unless network policies are managed by the same organization and by people with the appropriate skill set. CLICK: Cascade Shark Virtual Edition monitors all inter-VM traffic crossing virtual switch, providing real-time and historical visibility into virtualize server environments. Itsimultaneously captures and stores packet data on the server or SAN while sending flow data to Cascade Profiler to provide unified visibility into performance of multi-tier apps across physical & virtual network.
- Almost every enterprise big and small is moving very strongly toward a more fully virtualized IT environment. Industry analysts Gartner, Forrester, ESG and EMA all point to this transformation as top priorities for CIOs. Virtualization brings with it great promises of flexibility, cost savings, data and intellectual property centralization and most importantly enablingIT infrastructure to dynamically adapt to the needs of applications that drive a business’ top and bottom line. This value comes with a cost however in the form of significant complexity for the Network and IT operations staff who are tasked with ensuring the performance of applications and the networks they run over. CLICK: With this new release Cascade provides network and IT operations with a complete solution for managing network and application performance issues across all major virtualization areas: Server Virtualization, VDI and SDN.
- Like milk and cookies, Cascade and Steelhead solutions are better together…
- By no means it is required to purchase Steelhead WAN optimization with Cascade performance management, but for those IT organizations that do, they gain addition synergies and additional benefits.First of all, all Steelhead products can send CascadeFlow, an optimization-aware version of NetFlow, to Cascade Profiler, which provides rich details into what applications are using the WAN, response time information, QoS classifications, and optimization-aware reporting.And secondly, nearly all Steelhead products running RiOS 7.0 or greater (with the exception of the EX line at the time of publishing) have on-demand packet capture capabilities built in using the embedded Shark functionality. Embedded Shark functionality provides an easy-to-use and convenient method for troubleshooting performance problems at remote sites. All that is needed to take advantage of the on-demand packet capture on Steelhead is Cascade Pilot (version 3.0 or later). Cascade Pilot, the graphical user interface for analyzing packet data and transactions, functions as the management console, allowing you to schedule,start and stop packet capture jobs remotely. Bottom line: Every customer with Steelheads running RiOS 7.0 should purchase Cascade Pilot! This allows them to take advantage of the built-in troubleshooting capabilities while getting their first exposure to Cascade! Remember you only need one Cascade Pilot license per user not per Steelhead.
- CIFS protocol supportThe Common Internet File System (CIFS) is a network protocol that is commonly used by Microsoft operating systems and applications like SharePoint for sharing files across the network. CIFS is widely used because of its simplicity, but it is very “chatty” and inefficient, especially across the WAN. Cascade Pilot provides visibility into CIFS transactions, enabling customers to measure and analyze CIFS end-user activity; monitor application-level transactions by file, directory, and user; provide metrics on commonly used files, transfer times, and errors. Customers using Steelhead® WAN optimization products to accelerate CIFS will benefit from understanding file transfer times and optimization benefits.Support for VDI applications: Citrix XenDesktop and VMware View Cascade Pilot now also supports ICA and PCoIP, two popular VDI protocols used by Citrix XenDesktop/XenApp, and VMware View, respectively. With this release, customers gain visibility into the virtual channels of these VDI protocols, including their bandwidth consumption and priorities. Customers can also see the latency of critical actions such as print, keystrokes, mouse movements, file sharing, and screen refreshes. Having detailed visibility into specific VDI actions is not only critical to troubleshooting issues, but is also essential for optimizing the performance of these applications across both the WAN and LAN.

- Virtualizing the Cascade product lineCascade (v.10.0) completes the virtualization of the Cascade family that was started with Cascade® Shark Virtual Edition. Cascade® Profiler appliances and Cascade® Gateway appliances are now available as virtual solutions, providing deployment flexibility for managed service providers or enterprises looking to embrace virtualization or SDN.Cascade Profiler Virtual Edition is a virtualized version of the Cascade Profiler appliance for centralized reporting and analysis. Cascade Gateway Virtual Edition is a virtualized version of the Cascade Gateway flow collector. Both are available on VMware ESXi version 4.1 and 5.0.
- Cascade 10.0 also provides a number of additional enhancements95th percentile reporting in Cascade Profiler – New bandwidth-intensive applications such as video, social media, etc. are consuming bandwidth and stressing the network. Network administrators need an accurate way to identify high link utilization. Average and peak link utilization either under state or overstate the real link utilization. 95th percentile is a widely used calculation for evaluating the regular and sustained utilization of a network connection as it better reflects the required capacity of the link in question than other methods (such as average or maximum rate) and is useful for network capacity planning and billing. Although 95th percentile reporting is the most commonly used metric, this feature is easily configurable to support other thresholds.Cascade Pilot View Editor – Cascade Pilot views are rich, visual representations of application and network data that helps to streamline packet analysis and troubleshooting. Cascade Pilot View Editor introduces the ability to customize existing views or build new ones.Pcap-ng support – Pcap-ng is the new default packet capture file format for Wireshark® software. It is more complete and flexible than its predecessor (pcap) and includes support for nanosecond granularity. Cascade Shark and Cascade Pilot products now support pcap-ng files by default, allowing users to better leverage new Wireshark capabilities by storing capture files in pcap-ng format with nanosecond granularity.1GB fiber NIC card that supports both SX and LX transceivers is now available for use with all Cascade Shark appliances.Cascade Shark system diagnostics provides disk status, SNMP polling, and email alerting on the health of a Cascade Shark device, disk, and management interface, letting you know immediately in the rare event of a system problem.
- To summarize what you heard today:Cascade 10.0 provides a single, unified solution for managing performance of the entire virtual infrastructure: desktop, server, and network virtualization (in addition to the physical network, of course)Cascade’s new VDI and CIFS monitoring and troubleshooting further enhances the joint value with Steelhead and Granite The fully virtualized Cascade product family provides deployment flexibility for enterprises and managed service providers/systems integrators
