Penguin Solutions Supports Yurindo's Next-Generation Core System Transformation

Penguin Solutions Inc. (NASDAQ: PENG), through its Japanese subsidiary Penguin Solutions K.K. (Headquarters: Chiyoda-ku, Tokyo; President and Representative Director: Sanshiro Shoda; hereinafter 'Penguin Solutions'), announced that Yurindo Co., Ltd. (Headquarters: Yokohama, Kanagawa Prefecture; hereinafter 'Yurindo') has adopted the non-stop server 'Stratus ztC Endurance' (hereinafter 'ztC Endurance'), which provides 99.99999% high availability, as the platform for its next-generation core system responsible for sales and accounting management. The system has been operating stably without any issues for five months since its full-scale launch in November 2025. ■ A Simple High-Availability Platform Solving Complex System Configuration and Operational Load Challenges Yurindo, which operates approximately 40 stores primarily in Kanagawa Prefecture and is actively pursuing digital strategies including its own online store and YouTube channel, had identified the renewal of its information system as a key management issue. The previous core system employed a VMware-based cluster configuration, built in a complex environment with multiple servers, shared storage, and network devices. As hardware approached its renewal cycle, challenges arose including increased operational management burden due to the difficulty of identifying the root cause of system failures, and rising VMware licensing costs. To solve these issues, minimize the management load on IT staff, and ensure business continuity, 'Stratus ztC Endurance', which combines exceptional high availability with configuration simplicity in an on-premises environment, was selected as the new platform. ■ Key Decisive Factors for Adopting 'Stratus ztC Endurance' ● 99.99999% Continuous Availability 'Stratus ztC Endurance' is a platform equipped with fully redundant hardware in a single chassis and non-stop technology based on advanced fault prediction. Even when it detects signs of a failure, it automatically moves workloads from the active module to the standby module, continuing processing without any interruption to the running OS or applications. ● Simple Configuration Significantly Reducing Operational Management Load Despite its high availability, it requires no special scripts or configurations and is recognized by the OS as a single system. By adopting a Hyper-V virtualization platform in this configuration, the previous complex cluster setup was eliminated, resolving the VMware licensing issues. Module replacement is also easy, dramatically reducing the maintenance burden on IT administrators. ● Comprehensive Support and Excellent Total Cost Performance Penguin Solutions' support center provides a system for constant remote server monitoring using approximately 500 health check items. Additionally, support based on a premise of 10 years of long-term stable operation reduces the frequency of system updates and curbs medium- to long-term investment costs.
