Radisys,* Intel Deliver Telemetry Framework for Cloud Services Communications Service Providers Telemetry Introduction Communications service providers (CommSPs) have faced rapid-fire demands on their cloud service infrastructures, to roll out new services, keep up with emerging technologies, and stay ahead of unrelenting growth in user adoption. In response, CommSPs are rapidly deploying systems to grow and scale cloud environments, which is populating their cloud data centers with hardware from multiple vendors. Among other challenges, each vendor solution can bring varying telemetry functions, so that there is no unified reporting of the utilization of the physical and virtual resources. As a new entrant into the cloud systems market, the Radisys* DCEngine* needed to support the latest telemetry standards, including DMTF* Redfish.* The company teamed with Intel to embrace the Redfish open standard and give CommSPs unified tools to manage and rapidly scale their multivendor networks, while gaining the advantages of lowered costs and improved functionality. The Challenge Having a common telemetry is critical to being able to quickly scale pools of compute and storage resources to meet growing service demand. Each piece of network hardware offers different management solutions and different telemetry interfaces, and the lack of homogeneous interfaces impedes the ability for hyper scale-out. Integration requires resources, effort, and experience with the various protocols, tools, operations, and features of each solution. The skillset can be difficult to find, taking years to develop expertise. Previous management solutions based on the Intelligent Platform Management Interface (IPMI) specification were designed for common server features. When servers added differentiated features, IPMI offered only a reduced set of "lowest common denominator" functions (power on/off/reboot, temperature value, text console) that could work on all platforms. The IPMI telemetry for any vendor-specific functionality required expertly programmed extensions. As new hardware systems came on the market and the pace of change related to new features increased, this restriction limited the value of IPMI as a common management information protocol—especially in massive, hyperscale data center environments. The DMTF Redfish open standard was developed to provide a standardized interface that includes a common set of management APIs for a multivendor environment. Redfish can manage scale-out with compatibility across a broad spectrum of servers via its RESTful application program interface (RESTful API). The RESTful interface is based on the Open Data Protocol, which utilizes HTTPS and JSON to transfer data, making it ideal for the large multivendor server environments in cloud and web-based infrastructures. Unlike IPMI, the Redfish API is designed so Radisys* DCEngine* cloud server platform demonstrates support for Redfish* open standard telemetry across multiple Intel® Xeon® platforms. Solution brief
