Introduction

IBM® Flex System™ is a new platform technology that was introduced for organizations that are deploying IT for emerging data center applications, such as cloud computing, Big Data, Analytics, Technical computing, and Smarter Planet®. IBM Flex System combines advances in processor, memory, networking, storage, and management technologies such that they are integrated into a single, cohesive system. This system provides an efficient platform for addressing data center challenges for capacity, flexibility, scalability, reliability, and IT acquisition and maintenance costs.

There are several solutions available in the marketplace today for people who want to create private cloud infrastructures. Starting from the infrastructure layer, some vendors are providing “fully integrated” solutions with preselected components for almost all layers in the cloud.

2 Choosing IBM Flex System for Your Private Cloud Infrastructure

For example, IBM provides the BladeCenter® Foundation for Cloud1, which is reference architecture for creating a private cloud infrastructure by using the IBM BladeCenter, Intel processor-based BladeCenter servers, disk storage for virtual image repositories, integrated networking with 10 Gbps Ethernet and Fibre Channel over Ethernet (FCoE) switches, and the IBM SmartCloud™ Entry software stack for virtualization and platform management.

Although fully integrated solutions might address the needs of certain customers, the other end of the market segment is interested in creating their own private cloud infrastructures by integrating the piece parts. The IBM Flex System provides all of the components that are necessary for creating the cloud, including compute, networking, storage, and management software. In this paper, we describe how to integrate a custom private cloud infrastructure solution by using the IBM Flex System.

This IBM Redpaper™ is intended for customers and IBM Business Partners who are creating custom private cloud infrastructures and looking for various hardware and software options that are available from IBM. This paper also provides a technical overview of the IBM Flex System components for cloud infrastructure architects and hardware integration specialists.

Private cloud requirements

In constructing a private cloud infrastructure, you must look at the full stack of requirements and address them individually. You also must ensure that all the individual layers of the stack are well-integrated to create a seamless cloud system.

The different layers of a typical cloud environment are shown in Figure 1. A more fine-grained view of the cloud shows other layers. These layers include the platform virtualization layer that is used for storage and networking, the middle-ware application layer that sits between the virtual images, and the management layers. However, from a high level, Figure 1 shows the important layers that almost every cloud environment features.

At the physical infrastructure layer, we have the compute nodes, servers, networking, and all the other necessary support hardware (for example, management appliances). This layer is the fundamental layer of the cloud and is where people who are creating private clouds must spend the most time to select the correct hardware components. This selection process is critical because the choices that are made at this layer drive the choices for the other layers farther up in the stack.

For example, selecting x86 based servers versus POWER® based servers drives the choices for the hypervisors and the virtualization management tools and affects the application choices.

In addition, key characteristics of the cloud environment, such as the performance, scalability, upgradability, serviceability, and manageability, is determined by the physical infrastructure layer. The per-VM metrics, such as the number of virtual CPUs, amount of virtual memory, disk capacity, and network bandwidth, also are influenced by the choices for the hardware components at the physical infrastructure layer.

Most often, the hardware choices also are driven by the layers that are above the Physical Infrastructure layer, as shown in Figure 1 on page 2. For instance, applications that require much compute capacity and memory, such as database servers, force you to choose a robust, high-end platform with multiple CPU sockets. Also, support is needed for large memory (for example, a four-socket server with 64 memory DIMMs).

In 2012, IBM introduced a new hardware platform, IBM Flex System, which is a set of technologies that are designed to address many challenges. These challenges include IT complexity, growth, deployment, acquisition, and maintenance costs. The new platform also was designed to address the IT infrastructure needs of emerging markets, such as cloud computing, Business Analytics, Big Data, and Smarter Planet.

IBM Flex System enables new integrated solutions that are optimized on the hardware platform to take advantage of the full system capabilities for performance, scalability, robustness, and Systems Management. IBM Flex System provides an efficient platform to customers for addressing some of these challenges. It is an ideal platform for organizations that are creating their own solutions, such as custom private cloud infrastructures.

Advantages of PureFlex over Flex System

Although IBM PureFlex System is based on the Flex System building blocks, PureFlex provides the following advantages over Flex System:

� Infrastructure Solution

PureFlex provides an infrastructure platform solution by combining the Flex System chassis elements with the other necessary components at the rack level, such as top-of-the-rack network or SAN switches, external storage enclosures, and power distribution.

� Factory Integration

PureFlex is delivered as a fully integrated platform solution. When you order one of the PureFlex offerings (Express, Standard, or Enterprise), the system is fully assembled by IBM manufacturing. The system includes the hardware assembly, racking, and cabling, and is shipped as a single unit.

However, Flex System is not delivered as a fully integrated system. When the Flex System and the respective parts, such as switches, storage, and power distribution units (PDUs) are ordered, these elements are not integrated by IBM manufacturing. The elements are shipped as stand-alone items to be integrated by the customer or an IBM Business Partner.

Page 8: Choosing IBM Flex System for Your Private Cloud Infrastructure

8 Choosing IBM Flex System for Your Private Cloud Infrastructure

� Flexibility

PureFlex is offered as predefined configurations, which are pre-built bundles of hardware and software. However, within these configurations, there is much built-in flexibility for the various choices. For example, customers can add compute nodes or storage capacity that is based on their application needs in any of the configurations within the allowed limitations to keep the key aspects intact. PureFlex configurations can be customized but still benefiting from the integration and delivery principles. PureFlex also is designed so that a customer can start with any of the three offerings (Express, Standard, or Enterprise) and scale that environment to the next level (for example, Express to Standard, or Standard to Enterprise).

� Built-in expertise

PureFlex incorporates the best practices of IBM in architecture, integration, test, and deployment to create a robust platform solution. The choices of the hardware components, such as compute nodes, network switches, storage, and management are influenced by various factors that include typical customer technical needs, application demands, and solution cost versus functionality trade-offs. Hence, PureFlex System is optimal for a broad set of applications and still allows sufficient leeway for customization and tuning for specific applications.

� Simplified configuration and ordering

IBM configuration tools allow easy configuration of the PureFlex bundles. IBM trained sales people and IBM Business Partners can create PureFlex configurations by using either of the build-to-order configurations of IBM, x-config or e-config. The tools provide a simplified interface to build PureFlex configurations that start from the base offering building blocks and allow further customization according to the built-in rules to preserve the solution integrity.

Depending on the specific sales channel that is used, you can order PureFlex through one of the ordering systems: AAS, XCC, or HVEC. Although Flex System also can be ordered through one of these channels, it is up to the sales person or IBM Business Partner to choose the options to configure. They make these choices by using the configurator tools to ensure that the solution is valid and is not missing any critical components.

� Deployment services

PureFlex System bundles before the November 2012 announcement included lab services days for on-site integration at the customer site. Post the November 2012 announcement, this implementation service is optional, although customers or partners can include the services for an additional price.

The advantage of lab services is that the IBM trained professionals ensure the deployment and integration of the PureFlex solution into the customer environment. The Flex System BTO does not include services by default. A custom services agreement should be negotiated with the lab services that based on the specific customer needs.

A comparison of Flex System and PureFlex System is shown in Figure 3 on page 9.

Cloud reference architecture with Flex System

In this section, we describe sample configurations of a private cloud system that uses the Flex System components and the various hardware options that are available in Flex System.

Sample configuration

The rack-level diagram (without cabling) of a private cloud system that uses Flex System hardware is shown in Figure 4.

Figure 4 Front and rear view of a sample cloud that uses IBM Flex System hardware components

The configuration that is provided here is for reference only. The specific hardware choices are described at a high level to illustrate the different components that are available in the Flex System for building a custom cloud. The actual hardware choices, such as the number and type of compute nodes, type of processors, amount of physical RAM, disk storage capacity, and networking and SAN switches, are largely dependent upon various factors. These factors include the virtual machine (VM)-specific metrics, system performance requirements, scalability, redundancy, and environmental restrictions (power, cooling, space). Detailed requirements analysis and planning should be conducted to design the system and make the component selections that meet the requirements.

The example system that is shown in Figure 4 consists of a single Flex System Enterprise Chassis that is populated with compute nodes, redundant scalable chassis switch modules for Ethernet and SAN, and chassis management modules. The rack also includes a disk storage system with an entry storage controller and an expansion module. In addition, the rack consists of top-of-rack Ethernet switches for management and data networks.

Networking architecture

Often in a cloud environment, there are multiple network fabric types for various functions. Figure 5 shows these different fabric types and their purpose. From a virtual machine standpoint, there are three types of fabric: service management, storage access, and user/data.

Figure 5 Network fabric types for private cloud

These fabric types are described in the following subsections.

Service management networkThis network fabric is used for managing the physical and virtual resources. This network fabric often is physically isolated from the other fabrics for better isolation, security, and reliability of the management fabric. This same fabric is used for in-band and out-of-band management, although some customers prefer to isolate the in-band management from out-of-band.

The in-band fabric is used for managing the operating systems and hypervisors. For example, communicating with the VMware ESXi server from the management node for deploying virtual images on the compute node. At the same time, the same fabric is used for monitoring the operating system resources in-band by using platform agents, for example, IBM Systems Director agent.

Physical hardware resources, such as the compute nodes, network switches, and storage controllers, are managed via the out-of-band network fabric. For example, managing the Intel x86 compute nodes by using their Integrated Management Module (IMM) interface via the Flex Chassis Management Module (CMM) is done via the out-of-band network. The service management network fabric often is 1 Gbps Ethernet because of the low-bandwidth service traffic.

Page 12: Choosing IBM Flex System for Your Private Cloud Infrastructure

12 Choosing IBM Flex System for Your Private Cloud Infrastructure

User access/data networkThis fabric is used for communication from the client network to the virtual machines. This fabric also is used for data access to and from the VMs. This fabric is also used for remote access of the VMs. For example, if the VM is running a desktop environment, this access fabric is used for remote login to the desktop. This fabric often is 10 Gbps Ethernet. Optionally, it can be 1 Gbps Ethernet if the fabric is not to be used for heavy traffic.

The compute nodes should have the appropriate network interface cards to support the data fabric. The compute node of Flex System (for example, Intel x86 based x240 server) should have the embedded on-board 10-Gbps daughter card or a separate PCIe adapter installed. In addition, the Flex System chassis should have 10 GbE switches that are installed to support the 10-Gbps network to the nodes.

Storage networkThis fabric is used for providing access to the attached disk storage, which often is used in a private cloud environment for storing virtual image templates library. It also provides storage for the VM file system data storage for applications that run inside the VMs.

An entry-level or mid-range disk storage system, such as the IBM DS3000, DS5000, or IBM Storwize V7000 series storage controllers, are attached in a storage area network (SAN) type configuration as the storage solutions for small-scale private cloud environments.

For larger-sized clouds that require storage for large volumes of data (hundreds of thousands of VMs or mission-critical environments), a high-end storage solution such as the IBM XiV can be used.

Page 13: Choosing IBM Flex System for Your Private Cloud Infrastructure

Choosing IBM Flex System for Your Private Cloud Infrastructure 13

Figure 6 shows how the different types of network connections are made in the sample cloud configuration.

Figure 6 Network connections for sample cloud configuration

Depending upon the performance, scalability, protocol support, administration preferences, and cost considerations, various SAN interfaces can be used. These interfaces include the traditional Fibre Channel (8 Gbps or 16 Gbps speeds), Serial Attached SCSI (SAS) (6 Gbps speed), iSCSI (1 Gbps or 10 Gbps speeds), or Fibre Channel over Ethernet (FCoE) (10 Gbps speed).

The different Flex System component choices that are available for building a private cloud system are summarized in Table 1 on page 14.
