Saisi x Alibaba Cloud | Saisi PTP Time Synchronization Solution: 30ns Precision Weaves a Boundless Global Computing Network

Saisi Global Distributed Data Center PTP Solution: Empowering Alibaba Cloud to Accelerate the Construction of a "Unified Global Cloud Computing Network"

01 Alibaba Cloud: A Unified Global Cloud Computing Network

As a world-leading provider of cloud computing and artificial intelligence services under the Alibaba Group, Alibaba Cloud is committed to delivering a full-stack portfolio of cloud services to global customers, spanning elastic computing, storage, databases, and AI large models.

In recent years, Alibaba Cloud has been accelerating the development of a "Unified Global Cloud Computing Network" to support the overseas expansion of Chinese enterprises and the digital transformation of global clients. At its core lies a geographically distributed yet logically unified architecture, which breaks through the temporal and spatial constraints of traditional computing. By building a distributed cloud data center network, it serves as a critical underpinning for seamless cross-regional computing collaboration.

However, enabling efficient coordination among cross-regional nodes faces a core challenge: massive data exchange and computing resource scheduling rely heavily on ultra-high-precision time synchronization. Even a nanosecond-level (one-billionth of a second) time deviation can trigger systemic risks, such as disordered financial transaction sequencing, multi-node database state conflicts, and the failure of cross-border AI computing collaboration.

02 Saisi Global Distributed Data Center PTP Solution

To mitigate such risks and deliver optimal services, Alibaba Cloud and Saisi have forged a deep collaboration to launch the Saisi Global Distributed Data Center PTP Solution. This initiative integrates Saisi’s cutting-edge time synchronization technology with Alibaba Cloud’s robust global infrastructure, weaving key nodes around the world into a unified computing grid.

To date, the Saisi Global Distributed Data Center PTP Solution has successfully empowered efficient collaboration across core businesses—including data exchange and computing scheduling—across 29 regions and 89 availability zones of Alibaba Cloud’s global footprint.

As the chief designer of the time synchronization solution for the Qingyang hub, a key node of China’s national "Eastern Data and Western Computing" project, and a long-term strategic partner of Alibaba Cloud, Saisi has deployed its ultra-high-precision PTP time synchronization servers across Alibaba Cloud’s global data center nodes as part of this solution. These servers inject precise time signals, erasing spatial distances through accurate timing and enabling a transformative leap from geographical constraints of resources to seamless global collaboration.

The Saisi SM2500 ultra-high-precision PTP time synchronization server, a core component of the solution, is a synchronization clock compliant with the IEEE 1588v2 protocol, boasting a synchronization accuracy of 30 nanoseconds. Its fully redundant design—covering power supply, clock, input, and output modules—ensures exceptional product safety and reliability, further fortifying the stability of the computing network.

03 Saisi Electronics: The Preferred Choice of Leading Enterprises

Amid the global wave of digital and intelligent transformation, only when "time and frequency" are synchronized can the digital world achieve "harmonious resonance".

With over a decade of leadership in the time synchronization sector, Saisi has leveraged the irreplaceability of its product technologies, robust localized service capabilities, and long-term strategic commitment to build a portfolio of world-class projects. These include iconic cases such as the Mexico City Metro (one of the world’s top 10 PPP benchmarks), the Addis Ababa–Djibouti Railway (Africa’s first electrified railway), and the Jakarta-Bandung High-Speed Railway (a flagship high-speed rail project in Southeast Asia). Moreover, Saisi has established strategic partnerships with leading enterprises across multiple industries, achieving a remarkable leap from "Made in China" to a globally recognized brand.

Building on this foundation, Saisi has become the preferred choice of over 1,000 leading enterprises worldwide, with its partner network spanning more than 10 countries and regions across four continents. Looking ahead, Saisi will continue to deepen its global footprint, gain keen insights into market demands, integrate its core technologies into the timing backbone of thousands of industries, and contribute to the development of global infrastructure.
