  • 3. Introduction This document describes the reference architecture for deployment of the VMware vCloud Enterprise Suite on the IBM® PureFlex™ System hardware. The IBM and VMware teams worked together on the architectural vision and joint engineering effort to create this reference architecture. The target audience of this document is IT architects or technical managers supporting deployment of virtual cloud solutions. Business problem and business value The following section provides a summary of the business problem(s) that this reference architecture is intended to help address, as well additional value that this solution can provide for cloud deployment. Business problem Cloud infrastructures are now commonly used to rapidly build and deploy compute, storage, and networking resources to support mission-critical operations. Cloud environments provide an operational flexibility and decrease total cost of ownership (TCO) for investment made in hardware and software by simplifying administration, increasing resource utilization and availability for the services they provide. To increase the ease of virtual data center deployment, it is important not only to provide server, storage, and networking hardware and software tools, but to provide a standardized solution that can offer optimization opportunities for every aspect of virtual cloud deployment, including the functional software, cloud management tools, hardware (server, storage, and networking), speed to infrastructure readiness, and provisioning of cloud services and application deployments on demand. Business value This reference architecture is the result of collaborative work between IBM and VMware and is intended to deliver value for partners and customers considering deployment of a cloud infrastructure. The value of this reference architecture is in providing a footprint for accelerating deployment of cloud environments. This solution design achieves this objective by:    Introducing the VMware vCloud Suite, a software suite that contains the components needed to provide and manage cloud services. The vCloud Suite can provide core services such as self-provisioning of virtual resources and can easily be expanded to include advanced cloud services, such as workload deployment and automation. Introducing the IBM PureFlex System hardware platform, which provides a robust, scalable, and completely integrated computing, storage, and networking facility, with a standard physical footprint contained in a single 14U chassis. Providing a platform foundation for a Cloud Application Deployment Toolkit that enables deployment of traditional non software as a service (SaaS) independent software vendor (ISV) workloads in the production cloud, providing customers with SaaS-like experience (that is, quick access to a deployed application), while enabling service providers to automate and speed up time to deployment for mission-critical applications. IBM PureFlex System and VMware vCloud Enterprise Suite Reference architecture
  • 4. The combination of these software and hardware components and automation provide a distinct advantage for cloud deployment, making easier work of component ordering, simpler setup, configuration, ongoing management, and support. Requirements The following section documents several potential use cases for new cloud deployment, as well as specific requirements that are typical for cloud enablement projects. The component and deployment models demonstrated in this document apply universally to these use cases. Use cases Figure 1: Use case model IBM PureFlex System and VMware vCloud Enterprise Suite Reference architecture
  • 5. Requirements Table 1 provides an overview of the intended behavior of the system.

  • 6. Redundancy Solution components are redundant Hardware architecture ensures no single point of failure (SPOF), VMware vSphere software configuration ensures high availability / clustered configuration and distributed resource scheduling High availability Solution support for dual or multi-site tenancy PureFlex System plus vCloud Suite solution can extend to multiple sites using SRM but is not covered in this reference architecture. Automation Reduce complexity Cloud Application Deployment Toolkit referenced in this reference architecture. VMware vCloud Automation Center is not covered in this reference architecture. Table 1: Functional requirements for a vCloud Suite solution IBM PureFlex System and VMware vCloud Enterprise Suite Reference architecture
  • 7. Architectural overview This reference architecture includes VMware components supporting a software-defined data center (cloud environment) running on the IBM PureFlex System hardware. Some understanding of the individual components that consist of the VMware vCloud Suite is an important prerequisite to undertaking a cloud deployment. The VMware vCloud Suite is a suite of software products designed to enable cloud deployment. This reference architecture focuses on the vCloud Suite Enterprise offerings, highlighted in Figure 2. Figure 2: The VMware vCloud Suite The vCloud Suite reference architecture implementation consists of the vCloud Suite Enterprise software components installed into a vCloud Suite Management cluster, hosted as virtual machines inside a standard VMware vSphere environment. These components can support all aspects of configuration, security, administration, and reporting needed to support the cloud environment. The vCloud Suite components collectively manage access to a pool of virtualized resources available to vSphere. These resources can be used by consumers of cloud resources. The sizing of the resource pool depends on many factors which are discussed at length in a collection of documentation and sizing resources from VMware called vCloud Architecture Toolkit (vCAT). This toolkit is available at: www.vmware.com/cloud-computing/cloud-architecture/vcat-toolkit.html This reference architecture does not provide sizing guidance for vCloud Suite deployment, but provides a general approach for successful vCloud Suite deployment using IBM Flex System™ hardware. IBM PureFlex System and VMware vCloud Enterprise Suite Reference architecture
  • 8. Figure 3 provides a summary view of the VMware vCloud Suite and its interaction with the VMware vSphere hypervisor. Figure 3: The VMware vCloud Suite overview Figure 4 provides a logical view of both the vCloud Suite management cluster and the pool of vCloud Suite consumer resources. This reference architecture focuses primarily on the management cluster component installation, as appropriate sizing and allocation of consumer requires work that is detailed extensively in the vCloud Architecture Toolkit, (in the “Appendix 2: Resources” section of this document). IBM PureFlex System and VMware vCloud Enterprise Suite Reference architecture
  • 9. Figure 4: Distinguishing the management cluster from consumer resources Having discussed the structure of the VMware vCloud Suite of software products and their role in cloud deployment, the following sections address the hardware used in this reference architecture. The IBM PureFlex System platform has been used to meet the hardware requirements in support of this reference architecture. All the components required to support vCloud Suite (including computing, networking, storage, and management interfaces) can reside in a single 14U chassis. If needed, this platform can be easily expanded to multiple IBM PureFlex System chassis, allowing scalability in a common infrastructure platform. This approach ensures a highly standardized deployment of cloud services. Figure 5 provides an overview of the IBM PureFlex system platform. Key differentiators resulting from the IBM PureFlex System chassis and Flex System component designs in the context of cloud services include:  Application density, providing support for more workloads than with a traditional server, storage, or networking footprint  Faster installation time for supporting cloud infrastructure  Increased performance resulting from integration of physical architecture, management interfaces, and optimization functions in every component that serves the cloud.

  • 12. Figure 7: Description of the vCloud Suite components Cloud Application Deployment Toolkit IBM PureFlex System hardware and VMware vCloud Suite have been tested with the Cloud Application Deployment Toolkit created by VMware. This toolkit enables deployment of traditional non-SaaS ISV workloads in the production cloud, providing customers with SaaS-like experience (that is, quick access to a deployed application), while enabling service providers to automate and speed up time to deployment for mission-critical applications. Using this toolkit on the IBM PureFlex System hardware, a service provider can offer non-SaaS multitiered enterprise ISV applications as managed services to its customers. Upon customer request, these applications can be deployed automatically in a production-ready environment and can be tailored for a customer.

  • 15. Systems management IBM Flex System Manager is designed to optimize the physical and virtual resources of the IBM Flex System infrastructure while simplifying and automating repetitive tasks. It provides easy system setup procedures with wizards and built-in expertise, and consolidated monitoring for all of your resources, including: compute, storage, networking, virtualization, and energy. IBM Flex System Manager provides core management functionality along with automation. It is an ideal solution that allows you to reduce administrative expense and focus efforts on business innovation. A single user interface controls the following features:  Intelligent automation  Resource pooling  Improved resource utilization  Complete management integration  Simplified setup The IBM Flex System Manager accelerates cloud deployment by providing the ability to provision compute node, networking, and storage resources to the VMware ESX software layer and supporting vCloud Suite components. These capabilities decrease deployment time significantly. VMware integration features:  Deploying hardware patterns from the FSM to new compute nodes, ensuring that a boilerplate of hardware adapter interfaces are logically assigned to the compute resources, as suitable for a new vCloud Suite compute node.  Installing IBM customized ESXi 5.1 images to the new compute nodes from inside the FSM interface  Providing VMware environment visibility / ESX resource inventory and topology views from within the FSM interface, including the ability to deploy new virtual machine images  Providing extensibility from the native vCenter server to the IBM PureFlex System hardware, using the specialized IBM Systems Director Upward Integration Module (UIM). Capabilities of the UIM include monitoring power and thermals of the IBM PureFlex System components, view and update firmware / software levels for various components in the chassis, and modify settings for predictive failure alerts in the chassis. A view of the UIM tab from the lab environment is shown in the following figure. IBM PureFlex System and VMware vCloud Enterprise Suite Reference architecture

More details about the IBM Flex System x240 Compute Node and available configuration options can be retrieved from: ibm.com/systems/flex/compute-node/x86/bto/x240/index.html Networking Networking components inside the IBM PureFlex System chassis include dual IBM Flex System Fabric EN4093 10GbE Scalable switches (shown in the following figure) connected to the compute nodes using two 10GbE local area network (LAN) on motherboard (LoM) ports. The 10GbE ports are recommended for vCloud Suite deployments. Figure 12:IBM Flex System Fabric EN4093 10GbE scalable Ethernet switch The EN4093 10GbE Ethernet switch in the IBM PureFlex System chassis offers unparalleled flexibility to grow networking capacity for vCloud Enterprise Suite deployments, providing linear scaling of network bandwidth as new compute nodes are added to the chassis. Figure 13 shows the location of the networking devices in the Flex System chassis. Redundant EN4093 10GbE Scalable switches reside in I/O module bays 1 and 2. The I/O module bays 3 and 4 are used for SAN switches (referenced in the “Storage” section of this document). IBM PureFlex System and VMware vCloud Enterprise Suite Reference architecture

  • 19. Recent testing demonstrates a sample bandwidth scaling as additional IBM Flex System x240 Compute Nodes are added to the chassis. Netperf results are provided in Figure 15  . Figure 15: Netperf results for EN4093 and IBM Flex System x240 Compute Nodes For additional details on the IBM Flex System Fabric EN4093 10Gb Scalable switch, view the documents located at: ibm.com/systems/flex/networking/ethernet/en4093_10gb_vf/  Netperf is a benchmark that can be used to measure the performance of many different types of networking. It provides tests for unidirectional and bidirectional throughput and end-to-end latency. For more information, refer to http://www.netperf.org/netperf/ This Netperf example is intended for demonstrative purposes using four 10GbE ports for the compute nodes. The vCloud testing has been conducted using two-port 10gbE LoM. IBM PureFlex System and VMware vCloud Enterprise Suite Reference architecture
  • 20. Network deployment best practices for this solution include:  Ensuring that physical ports on all the hosts in the cluster are associated using the vCenter interface to a single vSphere switch to ensure redundancy.  Creating separate, highly available port groups to support separation of management, VMware vMotion, and IP storage networks, if required. The IBM PureFlex System platform positions Ethernet switch hardware inside the chassis, providing inherent network performance improvement for activities that use network bandwidth (such as VMware vMotion) from traditional top-of-rack network switching.  Adjusting the MTU size from default of 1500 to 1524 on physical and virtual switches in the configuration to accommodate additional header information used by vCloud Director Network Isolation links.  Increasing maximum number of vNetwork distributed switch ports from 128 to 4086, allowing vCloud Director to create port groups, as needed, as part of virtual data center (vDC) provisioning.  Using VMware NetQueue to enable Intel Virtual Machine Device Queues (VMDq) support for the GbE ports.  Improving network performance by using the TCP offload engine (TOE) capabilities of x240 network adapters, by enabling stateless offload of the following tunables, including: o Checksum offload o TCP segmentation offload (TSO) o Jumbo frames (JF) o Large receive offload (LRO) Storage This reference architecture uses the native IBM Flex System V7000 Storage Node (as shown in Figure 16) to meet the storage requirements for the vCloud Suite management cluster deployment. Figure 16: IBM Flex System V7000 Storage Node This storage platform is modular, and designed to be installed and managed as an integrated part of the IBM PureFlex System chassis. As an extension of the IBM Storwize V7000 family of products, the storage node brings valuable functions, such as thin-provisioned volumes, mirrored volumes, real-time compressed volumes, SDD tiering (IBM Easy Tier®), IBM FlashCopy®, and remote copy features including Metro Mirror (synchronous) and Global Mirror (asynchronous). This storage node also has the ability to virtualize other heterogeneous SAN-attached storage devices, extending the life of existing IBM PureFlex System and VMware vCloud Enterprise Suite Reference architecture

The rich set of capabilities native to this disk system make it ideal for cloud infrastructure in single sites or extending into multiple sites for high availability or disaster recovery deployments. For additional detail on the IBM Flex System V7000 Storage Node, visit: ibm.com/systems/flex/storage/v7000/index.html For storage configuration, the IBM Flex System V7000 Storage Node user interface can be accessed through the IBM FSM. The IBM Flex System V7000 Storage Node can also be managed from within the vCenter server environment, using the IBM Storage Management Console for VMware vCenter. An example of the IBM Storage Management plug-in being used to create a new volume in the vCloud Suite lab environment is shown in Figure 17. Figure 17: IBM Storage Management plug-in Connectivity between the IBM Flex System x240 Compute Nodes and the IBM Flex System V7000 Storage Node is achieved using the IBM Flex System FC5022 16GB Scalable SAN switches, as shown in Figure 18.

  • 22. For additional details on the FC5022 SAN switch, visit: ibm.com/systems/flex/networking/fibrechannel/fc5022_16gb_esb/ Storage layout for vCloud Management Cluster The IBM Flex System V7000 Storage Node tested for this reference architecture consists of a redundant control enclosure containing drives allocated to four Redundant Array of Independent Disks (RAID) arrays , referred to as managed disks (MDisks), providing a total of 2 TB of usable capacity to the vCloud Suite environment. Of the available space, 1 TB has been allocated to the vCloud Suite Management Cluster, residing in a single data store. The storage pool hosting the volumes used for the vCloud Suite reference architecture consists of sixteen 136 GB, 15K rpm SAS drives, and six 200 GB SSDs, providing an optimized storage configuration for the vCloud Suite software stack it supports. Details on the storage pool land volume configurations are provided in Table 5 and Table 6. The Easy Tier function inside the IBM Flex System V7000 Storage node is capable of monitoring I/O activity and proactively relocating the busiest disk extents to the faster SSD volumes. This improves performance and maximizes flash storage utilization by ensuring that the SSDs are used only for the workloads that require the faster disk.

With support for 1 TB nearline SAS drives, the single control enclosure used in this reference architecture can provide up to 24 TB of raw capacity. Additionally, storage expansion units can be added to the chassis, IBM PureFlex System and VMware vCloud Enterprise Suite Reference architecture
  • 23. increasing capacity or performance without affecting access to other resources in the IBM PureFlex System chassis. Storage planning considerations  Ensure that all compute nodes in the IBM PureFlex System chassis have redundant paths to storage. This is simplified by the storage provisioning capabilities accessible from the IBM FSM software. Appropriate zoning should be used to provide redundant paths between storage and compute node host bus adapters (HBAs) through dual, redundant FC switches in a PureFlex System chassis. This configuration protects the host from an I/O failure at both: the adapter and switch levels.  All compute nodes in the vCloud management cluster should have access to the same data stores.  Raw Device Mappings are not supported in the vCloud infrastructure.  Consider using a smaller number of larger data stores. When sizing the data stores, the amount of space allocated should scale up to a calculation based on the number of vApps expected multiplied by an average size of those vApps.  An NFS mount will be required for vCloud Director to use as a transfer volume to temporarily store vApps. vCloud Suite sizing considerations There are many factors that contribute to an end-to-end sizing of an entire VMware vCloud environment. This section is intended to provide some high-level guidance for vCloud Suite management cluster configuration sizing, and an estimate of the number of virtual machines that IBM Flex System compute (processor / memory) resources can support. These estimates can be used to scale vCloud Suite design to meet specific customer requirements. Figure 19 outlines the general requirements for the vCloud Suite management components. IBM PureFlex System and VMware vCloud Enterprise Suite Reference architecture
  • 24. Figure 19: vCloud Suite component sizing Sizing for the vCloud Suite consumer resource cluster requires additional detail that is not in scope for this reference architecture, but specifics are available in the VMware white paper Architecting vCloud, available by downloading the VMware vCloud Architecture Toolkit, available at: www.vmware.com/cloud-computing/cloud-architecture/vcat-toolkit.html For comparative purposes, some high-level IBM Flex System x240 Compute Node to VM sizing is included here. These VM consolidation estimates represent the conclusions of IBM from testing and analysis of systems in a controlled environment. Actual performance characteristics can vary depending on individual customer configurations and conditions. IBM makes no representation or warranty that an individual user can achieve results equivalent to the levels stated. Figure 20 provides an estimate of the number of virtual machines that can be consolidated using a single IBM Flex System x240 Compute Node given three different memory configurations (8, 16, and 24 x 16 GB DIMMs). The chart provides a VM consolidation given a conservative (blue), moderate (green), or aggressive (amber) consolidation effort.

  • 25. Using the 3DPC configuration, a single Flex System chassis with 10 compute nodes using 384 GB of memory each (reserving 4U for the IBM Flex System V7000 Storage Node) can host an environment of up to 890 VMs, using an aggressive VM consolidation model.
