Private clouds offer scalability and self-service benefits of public clouds while allaying concerns about data security, control and reliability. Dell Red Hat Cloud Solutions help transform IT into a highly available, dynamic service-delivery center.
Accelerate IT service delivery with open private-cloud infrastructure

The cloud computing model has become a catalyst for pervasive change, as enterprises continue to develop innovative ways to take advantage of its inherent elasticity and scalability. The use of cloud computing is growing, and by 2016 this growth will increase to become the bulk of new IT spend, according to Gartner, Inc.1 2016 will be a defining year for cloud as private cloud begins to give way to hybrid cloud, and nearly half of large enterprises will have hybrid cloud deployments by the end of 2017. Cloud computing enables organizations to pursue new, dynamic business opportunities with flexible and scalable IT services designed to make IT a direct contributor to business results.

However, some organizations are concerned about data security as well as the control and reliability of public cloud deployments. Private cloud deployments mitigate these issues by helping organizations limit security exposures, eliminate external dependencies on service-level delivery, and provide control over security and audits for regulatory compliance.

Moreover, private cloud deployments have the potential to support a consumption-based chargeback model, providing organizations with built-in metering to measure and bill for the actual cost of delivering IT services. For example, a monthly bill for power, cooling, compute, storage, network and support costs based on consumption allows decision makers to adjust resource utilization and manage budgets with heightened transparency and clarity.

Dynamic, secure open cloud solution

Dell Red Hat Cloud Solutions accelerate private cloud adoption by delivering the infrastructure, software and services needed for quick deployment. The solutions include a certified and tested reference architecture that is built and co-engineered by Dell and Red Hat. The architecture provides configurations tailored for common use cases and workloads and helps support consistency in deployments.

The reference architecture builds upon 12th-generation Dell PowerEdge rack servers with the Intel® Xeon® processor E5-2650 or the Intel Xeon processor E5-2670 v2. These two-socket 2U rack servers provide a cost-effective foundation that is well suited for cloud deployments. The servers are designed with a comprehensive feature set, including the large storage footprint, leading-edge I/O capabilities and advanced management of 12th-generation PowerEdge servers.

The solutions integrate these Dell servers, as well as Dell storage and networking, with the enterprise-hardened Red Hat® Enterprise Linux® OpenStack Platform. The platform combines the industry-leading Red Hat Enterprise Linux operating system with the latest OpenStack® software distribution. The Red Hat distribution pulls together a collection of open-source project components that work together to form the OpenStack cloud-service framework.

The Red Hat Enterprise Linux OpenStack Platform is supported by Red Hat beyond the six-month OpenStack release cadence, making OpenStack easy to consume, deploy and maintain. Red Hat enables long-term stability by including security fixes, bug fixes, performance enhancements and selected OpenStack features that can be back-ported and implemented without disrupting production environments.

Reference architecture and configurations to tailor deployments

The Dell Red Hat Cloud Solutions reference architecture enables IT decision makers to begin evaluating OpenStack software and create pilots. The validated reference architecture offers an operational approach that is based on highly automated solution deployments. The reference architecture provides several configuration options to suit different needs and environments.

Proof of concept. The proof-of-concept configuration is designed for organizations getting started with OpenStack or building applications in a testing and development environment. This configuration provides just enough infrastructure — five servers and a network switch — to exercise OpenStack administration tasks, network configuration and application development.

Pilot. The pilot configuration is appropriate for those who are operating in a proof-of-concept environment with storage and want to perform entry-level testing of applications — essentially providing the beginnings of a production environment. The base configuration is typically capable of supporting more than 220 virtual machines across six OpenStack compute and three storage nodes.

Cluster building blocks for pilot. For additional capabilities, organizations can expand the pilot configuration by adding pre-configured compute, storage and infrastructure building blocks.

Production. If more clusters beyond those supported in the pilot configuration are needed, Dell can help organizations architect a production, or scale-out, deployment.

Additional components for cloud operations

OpenStack provides an infrastructure foundation for hyperscale cloud deployments. However, it is not a total solution. Depending on an organization’s objective, additional components may be required to operate the private cloud. These components help meet software development requirements, integrate with internal systems, provide pre-built templates and extend operational capabilities. Most OpenStack deployments also require customization and development efforts to meet the specific needs of different data centers.

One key component organizations should consider adopting is a cloud management platform to provide uniform operations management. Dell Cloud Manager, for example, enables IT administrators to deploy and manage applications across major private and public cloud platforms. Available as software as a service or as on-premises software, Cloud Manager provides a suite of tools for provisioning, managing and automating applications.

Foundation for private cloud environments

Private cloud deployments help IT organizations respond rapidly to changing business requirements and customer demands. Private clouds also provide agile software build and scale-testing environments for cloud applications. As a result, developers can optimize and deliver mobile, collaboration and analytics applications.

Dell Red Hat Cloud Solutions are well suited for enterprises looking to quickly deploy a private cloud. The solutions enable enterprises to build cloud infrastructures with integrated hardware, servers, storage, networking and enterprise-grade software. In addition, Dell ProSupport and Red Hat offer services to integrate, deploy and support the OpenStack solution throughout its lifecycle.
