Carrier-grade chassis

A carrier-grade chassis is a high-reliability, ruggedized server platform designed for telecommunications and enterprise environments, offering NEBS and ETSI compliance, high availability, and scalable compute, storage, and networking capabilities.

Overview

A carrier-grade chassis is engineered to meet the demanding requirements of telecommunications networks, central offices, and other critical IT environments. It provides high availability, environmental resilience, and integrated management for compute, storage, and networking resources. The Lenovo Flex System Carrier-Grade Chassis is a prime example, designed to support volatile workloads, virtualized networks, and cloud environments while maintaining operational continuity .

Key Features

• Rugged Design and Compliance: Built to NEBS Level 3 and ETSI standards, the chassis can operate in harsh environments, including Earthquake Zone 4 areas, and withstand ambient temperatures from -5°C to 55°C . It also includes dust filters and supports -48V DC power, common in telecom central offices .
• High Availability: The chassis has no single point of failure, supports redundant power supplies (N+N or N+1), and features optimized cooling with thermal ducting to manage airflow efficiently .
• Scalability: The 11U chassis can accommodate up to 14 standard-width compute nodes or seven double-width nodes, allowing flexible combinations of compute, storage, and networking resources .
• Management and Monitoring: Lenovo XClarity management software enables monitoring and automatic updates across multiple chassis, providing centralized control over power, cooling, and system health .
• Energy Efficiency: Power supplies are 80 PLUS Platinum-certified, and the system monitors power usage across all components for optimized energy consumption .

Applications

Carrier-grade chassis are ideal for:

• Telecommunications providers: Supporting central office operations and network functions.
• Managed service providers: Delivering reliable cloud and virtualized services.
• Original equipment manufacturers (OEMs): Integrating into high-performance, scalable infrastructure solutions .

Benefits

• Reliability: Ensures continuous operation in critical environments.
• Flexibility: Supports a mix of workloads and can scale with business needs.
• Environmental Resilience: Operates under extreme temperatures and seismic conditions.
• Simplified Management: Centralized monitoring and automated updates reduce operational complexity . In summary, a carrier-grade chassis like the Lenovo Flex System provides a robust, scalable, and highly reliable platform for telecommunications and enterprise IT, combining environmental resilience, high availability, and integrated management to support critical workloads efficiently.
