This article examines the difficulties of building non‑blocking services with Java NIO, compares blocking and non‑blocking pipelines, and presents practical designs for handling partial reads, dynamic buffers, message framing, and efficient write management to scale servers to millions of connections.
This article explains the Model Context Protocol (MCP), its components, and how to integrate MCP servers with Alibaba Cloud Observability 2.0, offering practical design experiences, tool simplification tips, default parameter strategies, output size control, and future AI‑driven observability insights.
Unlike traditional one‑request‑per‑process servers, Nginx uses a fixed number of worker processes with a non‑blocking, event‑driven model that reduces context switches, leverages epoll/kqueue, and handles thousands of connections efficiently, making it the preferred high‑performance web server.
This article presents a comprehensive reference design and performance evaluation of a 2U four‑node high‑density server employing full liquid‑cooled cold plates for CPUs, memory, storage, NICs, and power supplies, detailing system architecture, flow design, CFD validation, and future optimization directions.
This white‑paper presents a 2024 reference design and performance evaluation of full‑liquid‑cooling solutions for CPUs, memory, SSDs, PCIe/OCP cards, power supplies and IO boards, detailing architecture, advantages, implementation methods and deployment scenarios for data‑center and telecom applications.
This article details the architecture of a 2U four‑node liquid‑cooled server, explaining its component layout, serial flow design, heat‑capture calculations, and the engineering of CPU, memory, SSD, PCIe/OCP, IO, and PSU cold‑plate solutions that together remove about 95% of heat directly via liquid and the remaining 5% through a rear‑mounted air‑liquid heat exchanger.
The article examines the rise of chiplet technology, the UCIe interconnect standard, and CXL‑based memory expansion, analyzing technical specifications, scalability challenges of CPU memory channels, and future prospects of CXL 2.0 and 3.0 for server and cloud architectures.
Alibaba embeds lithium Battery Backup Units (BBU) directly into servers, creating a distributed power system that boosts efficiency to 99%, cuts PUE by up to 15%, reduces capital costs, and simplifies battery management for massive data‑center operations during events like Double 11.
