Hyperscale Ecosystems and VIAVI
VIAVI Solutions is an active participant in over thirty standards bodies and open-source initiatives including the Telecom Infra Project (TIP). But when standards don’t move quickly enough, we anticipate and develop equipment to test evolving infrastructure standards. We believe in open APIs, so hyperscale companies can continue to write their own automation code
The complexity of hyperscale architecture makes testing essential during network construction, expansion, and monitoring phases. Decades of innovation, partnership, and collaboration with over 4,000 global customers and standards bodies like the FOA have uniquely qualified VIAVI to address the unique test and assurance challenges faced by Hyperscalers. We guarantee performance of optical hardware over the lifecycle of the hyperscale ecosystem, from lab to turn-up to monitoring.
What is Hyperscale?
Hyperscale refers the hardware and software architecture used to create highly adaptable computing systems with a large quantity of servers networked together. The definition provided by the IDC includes a minimum threshold of five thousand servers on a ten thousand square foot or larger footprint.
Horizontal scaling (scaling out) responds to demand quickly by deploying or activating more servers, while vertical scaling (scaling up) increases the power, speed, and bandwidth of existing hardware. The high capacity provided by hyperscale technology is well suited to cloud computing and big data applications. Software defined networking (SDN) is another essential ingredient, along with specialized load balancing to direct traffic between servers and clients.
- How does Hyperscale work?
Hyperscale solutions optimize hardware efficiency with massive server arrays and computing processes designed to promote flexibility and scalability. The load balancer continuously monitors the workload and capacity of each server so that new requests are routed appropriately. Artificial intelligence (AI) can be applied to hyperscale storage, load balancing, and optical fiber transmission processes to optimize performance and switch off idle or underutilized equipment.
- Hyperscale Benefits
The size associated with hyperscale architecture provides benefits including efficient cooling and power distribution, balanced workloads across servers, and built-in redundancy. Hyperscale solutions also make it easier to store, locate, and back up large amounts of data. For client companies, leveraging the services of hyperscale providers can be more cost-effective than purchasing and maintaining their own servers, with less risk of downtime. This can significantly reduce time demands for in-house IT personnel.
- Hyperscale Challenges
The economies of scale that hyperscale technology provides can also lead to challenges. High traffic volumes and complex flows can make real-time hyperscale data monitoring difficult. Visibility into external traffic can also be complicated by the speed and quantity of fiber and connections. Security concerns are heightened since the concentration of data increases the impact of any breach. Automation and machine learning (ML) are two of the tools being used to improve observability and security for hyperscale providers.
The ability to precisely match memory, storage, and computing power allocation to changing service requirements is a characteristic that sets hyperscale apart from traditional data center models. Virtual machine (VM) technology allows software applications to be rapidly moved from one physical location to another. High-density servers, parallel nodes to improve redundancy, and continuous monitoring are other prevalent features. Since no single architecture or server configuration is ideal, new models are being developed to address evolving operator, service provider, and customer needs.
- What is Hyperscale Cloud?
The internet and cloud computing have reshaped the way applications and data storage are accessed by users. By transferring these functions from local servers to remote data centers managed by large cloud service providers (CSPs), businesses can ramp up infrastructure on demand without impacting in-house operations. Hyperscale cloud providers add a supersized level of data center capacity and elasticity to traditional cloud offerings such as software as a service (SaaS), infrastructure as a service (IaaS), and data analytics.
- Hyperscale vs Cloud Computing
Although the terms are sometimes used interchangeably, cloud deployments do not always reach hyperscale proportions, and hyperscale data centers support much more than cloud computing. Public clouds used to deliver resources to multiple customers over the internet (cloud as a service) often fall within the hyperscale definition, although private cloud deployments can be relatively small. When an enterprise data center built and operated by an organization to meet its own data processing and storage needs incorporates hyperscale size and orchestration properties, the result is known as enterprise hyperscale.
- Hyperscale Cloud Providers
Hyperscale cloud providers invest heavily in infrastructure and intellectual property (IP) to meet customer requirements. Interoperability becomes important as customers look for portability across standardized platforms. Synergy Research Group data shows that the three largest players: Amazon Web Services (AWS), Microsoft, and Google, account for over half of all installations. These three providers are also leading planning and development efforts for hyperscale edge data centers needed to meet evolving 5G and IoT requirements.
- Hyperscale Colocation
Colocation allows a business to rent part of an existing hyperscale data center rather than building a new one. Hyperscale colocation can create useful synergies when related industries, such as retail and wholesale vendors, are under the same roof. Overall costs for power, cooling, and communication are reduced for each tenant while uptime, security, and scalability are markedly improved. Hyperscale companies can also improve their efficiency and profitability by leasing excess capacity to tenants.
- Hyperscale Architecture
Although there is no set definition for hyperscale architecture, common characteristics include petabyte level (or greater) storage capacity, a discrete software layer performing complex load balancing and data transfer functions, built-in redundancy, and commodity server hardware. Unlike servers used by small private data centers, hyperscale servers typically use wider racks and are designed for easier reconfiguration. This combination of features effectively removes the intelligence from the hardware, instead relying on advanced software and automation to manage hyperscale data and scale applications quickly.
- Hyperscale vs Hyperconverged
Unlike hyperscale architecture which separates computing from storage and networking functions, hyperconverged architecture integrates these components within pre-packaged, modular solutions. With software-defined elements created in a virtual environment, the three components of a hyperconverged building block cannot be separated. Hyperconverged architecture makes it easier to scale up or down quickly through a single contact point. Additional benefits include bundled compression, encryption, and redundancy capabilities.
As hyperscale models become more distributed, edge computing and multi-cloud strategies are increasingly common. Connectivity must be assured for physical connections within the data center as well as the high-speed fiber links that seamlessly integrate hyperscale locations.
- Data center interconnects (DCIs) are used to link massive data centers to one another as well as intelligent edge computing centers around the world.
- DCI connection testing eases installation by quickly verifying throughput and accurately pinpointing sources of latency or other issues.
- PAM4 modulation and Forward Error Correction (FEC) add complexity to ultra-fast 400-800G Ethernet DCI connections.
Automated MPO connector inspection completed in seconds, simultaneous testing of multiple 400G or 800G ports, and virtual service activation and monitoring are some of the test capabilities required to keep pace with evolving hyperscale interconnect architecture.
Hyperscale Testing Practices
Many hyperscale testing practices for fiber connections, network performance, and service quality remain consistent with conventional data center testing, only on a significantly larger scale. Uptime reliability becomes more important even as the testing complexity grows. DCIs running close to full capacity should be tested and monitored consistently to verify throughput and find potential issues before a fault occurs. Automated monitoring solutions should be used to minimize resource demands.
The customization of data center hardware and software makes interoperability essential for premium test solutions. This includes test tools supporting open APIs to accommodate the hyperscale diversity. Common interfaces like PCIe and MPO that enable high density and capacity have grown in popularity and require solutions to efficiently test and manage them.
- Bit error rate testers like the MAP-2100 have been developed specifically for environments where little or no personnel is available to perform network tests.
- Network monitoring solutions intended for the hyperscale ecosystem can flexibly launch large-scale performance monitoring tests from multiple physical or virtual access points.
- Testing best practices defined for elements like MPO and ribbon fiber can be applied on a massive scale within deployments.
New hyperscale installations continue to add size, complexity, and density. Test solutions and products originally developed for other high-capacity fiber applications can also be used to verify and maintain hyperscale performance.
- Fiber Inspection: The high volume of fiber connections within and between data centers require reliable and efficient fiber inspection tools. A single particle, defect, or contaminated end-face can lead to insertion loss and compromised network performance. The best fiber inspection tools for hyperscale applications include compact form factors, automated inspection routines, and multi-fiber connector compatibility.
- Fiber Monitoring: The increase in fiber optics within the hyper scale data center industry has made fiber monitoring a difficult yet essential task. Versatile testing tools for continuity, optical loss measurement, optical power measurement, and OTDR are a must. This applies throughout all phases of construction, activation and troubleshooting activities. Automated fiber monitoring systems like the ONMSi Remote Fiber Test System (RFTS) can provide scalable, centralized fiber monitoring with immediate alerts.
- MPO: Multi-fiber push on (MPO) connectors were once used primarily for dense trunk cables. Today, hyperscale density constraints have led to rapid adoption of MPO for patch panel, server, and switch connections. Fiber testing and inspection can be accelerated through dedicated MPO test solutions with automated pass/fail results.
- High Speed Transport - 400G and 800G: Emerging technologies like the IoT and 5G with high bandwidth demands have made cutting-edge, high speed Ethernet standards like 400G and 800G essential to hyperscale solutions. Scalable, automated test tools can perform advanced error rate and throughput testing to verify performance. Industry standard Y.1564 and RFC 2544 service activation workflows also assess latency, jitter, and frame loss at high speeds.
- Virtual Test: Portable test instruments that once required a network technician on site can now be virtually operated through the Fusion test agent to reduce resource requirements. The software-based Fusion platform can be used to monitor networks and verify SLAs. Ethernet activation tasks such as RFC 6349 TCP throughput testing can also be virtually initiated and executed.
- 5G Networks: Distributed, disaggregated 5G networks bring more demand for hyperscale solutions and virtual testing of network functionality, applications, and security. The TeraVM solution is a valuable tool for validating both physical and virtual network functions and emulating millions of unique application flows to assess overall QoE.
