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

Saisi's global distributed data center PTP solution empowers Alibaba Cloud to accelerate the development of a unified global cloud computing network.

01 Alibaba Cloud, the Global Cloud Computing Network

Alibaba Cloud, a global leader in cloud computing and AI services under Alibaba Group, delivers end-to-end cloud solutions including elastic computing, storage, databases, and large-scale AI models to clients worldwide.

In recent years, Alibaba Cloud has been accelerating the construction of a "global cloud computing network" to support Chinese enterprises going global and the digital transformation of global customers. The core lies in breaking through the spatiotemporal limitations of traditional computing by building a distributed cloud data center network with geographically dispersed but logically unified architecture, thereby achieving key support for seamless cross-regional computing power collaboration.

The core challenge in achieving efficient cross-regional node collaboration lies in the heavy reliance of massive data exchange and computing power scheduling on ultra-precise time synchronization. A nanosecond-level (10^-9 second) deviation can trigger systemic risks, including financial transaction order disruptions, multi-node database state conflicts, and the failure of cross-border AI computing coordination.

02Saisi Global Distributed Data Center PTP Solution

To mitigate risks and deliver optimal services, Alibaba Cloud and Saisi have forged a deep collaboration to launch the Global Distributed Data Center PTP Solution. This initiative seamlessly integrates Saisi's time synchronization technology with Alibaba Cloud's robust global infrastructure, weaving together critical nodes worldwide into a unified computing power grid.

To date, Saisi's global distributed data center PTP solution has enabled efficient collaboration in data exchange and computing power scheduling across Alibaba Cloud's 29 regions and 89 availability zones worldwide.

As the chief architect of clock synchronization solutions for Qingyang's pivotal hub in China's national "East Data West Computing" initiative and a long-term strategic partner of Alibaba Cloud, Saisi has introduced its global distributed data center PTP solution. By deploying ultra-precision PTP time synchronization servers across Alibaba Cloud's worldwide data center nodes, the solution injects precise time signals that eliminate spatial distance constraints through synchronized timing, achieving a transformative leap from resource localization to seamless global collaboration.

The Saisi ultra-high-precision PTP time synchronization server SM2500 in this solution is an IEEE1588v2 compliant clock with 30ns synchronization accuracy. Its fully redundant power, clock, input and output design ensures robust safety and reliability, while also strengthening the computing power network.

03Saisi Electronics, the common choice of leading enterprises

In the global wave of digital transformation, only when time and frequency synchronize can the digital world achieve true resonance.

With over a decade of experience in clock synchronization, Saisi has created world-class PPP cases such as Mexico's subway system, Africa's electrified railway (Subway Jijilat), and Southeast Asia's benchmark high-speed rail (Jakarta-Bandung) through its irreplaceable product technology, deep localization services, and long-term strategic commitment. The company has also established strategic partnerships with leading clients across multiple industries, achieving a leap from China's intelligent manufacturing to an international brand.

As a result, Saisi has become the preferred choice for over 1,000 leading global enterprises, with its partner network spanning more than 10 countries and regions across four continents. Going forward, Saisi will further expand its global footprint, gain deep insights into market demands, and integrate its core technologies into the time-series processing systems of diverse industries, thereby contributing to the development of global infrastructure.
